- เผยแพร่เมื่อ 26 ส.ค. 2022
- In this video I'll go over why the Theta II engines that include the famous 2.4L and the 2.0L fail. These engines are in the Hyundai Sonata, Hyundai Santa Fe, Hyundai Genesis and the Hyundai Tucson but also in Kia Optima, Kia Forte and the Kia Sportage. I'll cover how they fail causing rod knock, seized engines, damaged cylinder walls, spun bearings, seized bearings, damaged timing chain, stretched timing chain, damaged piston rings, I'll also go over how you can diagnose and narrow down where the failure has taken place as well.

I had a 2010 Hyundai Accent and when I bought it the salesman told me to change the oil every 7-8,000 miles. I knew that was too many and instead did it every 4,000 miles. It ran great and I never had a problem with it during the entire time I owned it. I think these long oil change intervals recommended by the manufacturers are killing these engines.
Exactly, these car manufacturers want are cars to go to shit as soon as possible, so we buy new cars more frequently
Friend has a 2012 Sonata that caught on fire while her mechanic was driving it after a maintenance schedule.
Its long change intervals combined with both POOR quality engine oil (think bulk dums from Jiffy Lube) & also their poor quality oil filter made just for the oil change place. U cant buy such a filter that meets low specification at auto zone or walmart. AND then that same cheap owner uses poor quality regular unleaded that lacks the proper octane & detergent additives. The MFR rarely duplicates that scenario in their testing.
@@opinionsvary Well said! That’s why API created the “SP” specification to minimise LSPI and timing chain issues. Here in Europe, Tucsons come with the 1.6 DI Turbo engine which requires 0W-20 API SP oil. Their normal oil change states for 9300mi while the severe for 4600mi. Better stick with the severe though…
I just got a, 2023 Hyundai Sonata N-Line 2.5l turbo and I couldn't care less about engine problems as the warranty is, 10 year/100k mile warranty. Lol. So....I don't care if anything fails....I get it fixed/replaced for free. Ha also....I ALWAYS change the oil on a new car after the first 500 miles. Some engines just don't last as long as others. It happens....not a single engine and or car maker has an engine that has never had a issue or issues. Millions are sold and odds are, some will have issues, especially with some people driving em hard as all hell and not doing proper maintenance. Again, new hyundais now have a 10 year/100k mile powertrain warranty. So, couldn't careless about issues. Lol also, when buying a new hyundai, you can purchase a lifetime pwertrain warranty for around 2k.....so.....couldn't careless about issues.
My Thete 2.0 died right at 145,000 miles. Rod knock followed by seized engine. Brought to the Kia dealership and they said "nothing we can do, looks like negligence", and they offered me $500 as a trade in. I found out about the class-action lawsuit, and the warranty was raised to 150,000. I went to a different dealer, brought the settlement paperwork with me.... and they dropped in a reman for free.
Was that a hybrid?
As a tow truck driver from the auto club, I’ve picked up most cars with dead batteries, alternator issues and minor repairs needed, but kia and Hyundai are definitely the worst ones with blown engines.
Especially because people neglect to change the oil, or check fluid level 🫤
We hope to see you at Mollison OReilly’s!
Combine that with the way the owners drive. A lot feel they are driving a race car.
It's a manufacturing defect according to the video.
Hi Marco, good to see you here. The way I am buying cars that need work I'll be down there a bunch of times. Cheers
Well unfortunately these engines tend to burn through oil like crazy, I've had to replace oil 100 to 1000 miles after an oil change due to bad O rings, valve cover seals and oil pan gaskets...
We are lucky here in Australia. Our Kia and Hyundai cars come straight from Korea and we dont seem to have the problems your cars have in the USA. Also we change oil regularly here in OZ. I change my turbo Tucson`s oil twice a year with full synthetic oil...because I can. Never needed oil between services despite regular 2500km trips in hot weather.
This is why I do all my own oil changes, it's at least done right.
Done right?

@@nexpro6118 That is one good warranty. Will probably never have to use it.
Our 2012 Sonata suffered rod bearing failure at around 85,000 miles. This occurred right before Hyundai officially started their recall/repair program for those engines, but they investigated briefly and replaced it free of charge anyway. No issues since--great reliable car.
@Ratz Patootie They're the biggest auto manufacturer globally, they're nowhere near going out of business lol.
@Ratz Patootie Maybe you know something I don't, but as far as I know the companies are still pretty financially healthy. The Sonata still sells like crazy, as do the small and midsize SUVs. I'm sure these recall issues cut down their margins but they still seem to move a lot of units.
@Ratz Patootie how'd it go? Dropped mine off for diagnostic today. Rod knock and limp mode at 90.8k miles. I think I'll have to get a rental out of pocket and pray kia reimbursed me in the meantime.
@Ratz Patootie good lord. It's my only car too and I have work and not a ton of money saved up for a rental. I sure hope it goes well. It's kind of sadistic for Kia to not have done a true recall on these vehicles. I can't describe how lucky I was to not have broken down in rush hour traffic when it would have been much more dangerous. That's like 90% of my drive time. It's a shame too because I really liked my optima ex until all of this.
@Ratz Patootie thanks Ratz. Can we just communicate here? I'll email you if you want I suppose but I get notifications when you reply to this thread. I'm going to call the dealership shortly and see what's going on. It should have been sitting there for about 24 hours now so hopefully I'll at least have a positive diag code by now. He said they have 4 cars in for engine replacement right now and if I was a positive diag then he'd order the engine same day and probably 3 week overall wait for me 🤞 I also need to figure out a rental today so I'll be calling Kia consumer affairs beforehand to see what they'll do for me
The underlying problem is severe engine oil dilution which eats away the rod bearings and wears the timing chain. In addition, these drivetrains cruise at very low rpm (1000rpm) which causes cylinder ovaling. If you do mostly short drives, change oil no longer than 4000 miles/6 months and downshift manually so you don't cruise at 1000 rpm.
Why does n engine at medium to high load at low RPM cause cylinder ovaling? Are the side loads very high on the piston under those conditions?
I like your videos as they have a mixture of technical details, real life costing and discussion of the realities of the weak points of certain car brands. (Also the possible opportunities for profit if a person learns how to repair a known problem related to a certain model) You are a very productive guy building your own shop, landscaping, buying and selling vehicles and making good how to videos all at the same time! Thanks
glad you like the videos, cheers.
Same!
Wow, as a 50-year-plus mechanic I can tell you that the oil in that engine was not changed at regular intervals, hence the brown cooked look on the internal parts which will cause internal failures. All these small engines run at higher rpm's and higher temps so change your oil. In the 60s-70s, Fram filters' slogan was"You can pay me now or pay me much more later".

will do thanks for watching.
WOW, I haven’t checked into this site in a while. I learned how to do my Elantra timing belt here. That was when there were only maybe 20,000 subs. Now it’s 1,000,000. Good work!
You did good. My experience with no compression engines that have jumped time is to then pull all the cam caps and do a leakdown on all the cylinders. Your engine may have good valves. You might not have to pull the head. You are doing a timing chain/tensioner/water pump at this point no matter what. You know what you are doing. Great video.
I have missed your old mechanic videos, forgot how enjoyable they are.
Agreed. They’re almost therapeutic. :)
2.4 is rubbish. Wife had a 2017 Optima purchased with 26k miles. Spent more time in the shop and Kia were terrible to deal with. Yet my neighbour had exactly the same car and had zero issues and is still running strong.
yup 2.4L is terrible the 2.0L is much better but still you have to watch out for some years/make/models. cheers
I had a '17 Sonata 2.4 theta II and it was flawless up to the time I traded for '21 Sonata 2.5 smartstream.
The '17 Sonata had 60k when I traded it in.
@@dougn2350 my 2017 had issues with burning oil, a faulty knock sensor wire, an oil pan gasket that needed replacing and a valve cover gasket that needs to be replaced. It burns oil like crazy even after the oil changes.
Should have taken it to a mechanic before buying it. Probably wanted to get rid of it because they didn't do their scheduled maintenance and started having problems.
@@ronyoung9251 faulty knock sensor was the issue on my wife's Optima. Was a nightmare and left her stranded at least 3 times.
Good to see you post again. Congrats on one million subs!
In my Kia Rio I change the oil and filter every 5000km, with full Castrol synthetic oil. Runs like a dream. My philosophy with modern engines is, they only need good oil, early changes, and good coolant. I use Kia coolant, as used by the factory. Kias are good..
@@tessalcazaren 🐵🐒🦍🐵🐒🦍🐵🐒🦍
So you think owners of other car brands just take better care of their cars and Kia owners don't get oil changes? lol
What year your kia rio is? I just bought an 06 kia rio with 56k on it for $600. In good shape. Just changed timing belt, air filter, water pump, oil change, plugs, coil pack 4 new tires, alignment and service transmission.
@@retiredsnowbunnyhunterx5106 ...its a 2008...
Lots of varnish in there. My Ford Contour SVT has almost 300k, synthetic oil every 5000 miles. I changed the valve cover gasket at 275k and the engine looked new. It’s all maintenance, which most people don’t do.
Yep. Modern Synthetic/synthetic mix oils changed every 4/5k miles keeps internals looking new at 200k. Those cheap ass Korean engine’s definitely can’t handle that abuse😬!!!!
I'm changing my oil in my 2020 Tacoma 3.5L v6 every 5,000 to 6,000 Miles to in hopes that it will last and stay clean. With these new modern engines that have variable valve timing, small tolerances and small oil passages I feel like Toyota's 10,000 mile recommendation is too long to keep everything good.
@@steveo601 Are these Korean made, or from the American factory?
@@DrakeN-ow1imAmerican.
I had consistent maintenance and the records to back it up and I took care of my car and the engine is failing at 90k so I'm in the middle of oil consumption test to get a new engine. And my coworker said his niece has had to replace her engine twice. So absolute b*******
I own a 2012 KIA Sorento, with the 2.4L engine. Recently it turned 100,000+ Miles. My son, who gave it to us as a present, was very loyal with the oil changes--I taught him that! It's burning oil (about 1-and-a-half to 2 quarts between changes, which I do every 6 months or 5,000 miles, whatever happens first.) Until the financial situation eases off, that's our ride, period!
Kia spec is 1 qt per 1000 miles. But regardless if you have good maintenance records there should be a engine recall to cover failyre

Love Hyundai. My Elantra has 375k miles on it and still rips. That said it seems between 2008 and 2018 they had major engine issues. I'm not going anywhere near their theta engine.
Yup I consider some of the Elantras very reliable cars. Problem is their Theta II engine is terrible.
What year is your car?
I had a 2017 Elantra with the shitty Atkinson cycle engine. I babied it and still needed a new engine at 12,000 yes 12K miles due to excessive piston slap traded it in for a Mazda at 45K and will never ever again invest in Hyundai

Good to see you back on. Haven't seen any of your videos for awhile
I'm a new subscriber. Congrats on your 1.1M fan club. I'm not a mechanic but I appreciated very much how you explained things regarding the dead Hyundai engine. You have an accent but I still think you are in the states. There is no grass, so you must be out west. I just ran it through KBB and you are a little low. It is worth between $8,900 - $11,000. I had to fix my earlier quote because you want the private party value not the trade-in.. I ran it with standard equip and I wasn't sure if it was a manual or automatic, I also listed it as "Excellent" condition. I am amazed at how perfect the wheels are.
P.S. There is one recall on it.
I bought our 2011 Hyundai Santa Fe new, changed oil and maintained at all intervals. It has 143,000 miles and still seems very reliable. I had to have the starter replaced at about 90,000, thats it.
My wife has a 2016. She loves it and has been very reliable.

The bottom end failures are likely from failed journal hardening and/or machining swarf left behind. The other things that go wrong are in line with what Toyota, Honda, VW-Audi, BMW, and almost everyone else has seen: too long oil change intervals and sludge sticking low tension piston rings. A lot of stuff mentioned in these comments is not based on facts from car repair shops. Kia and Hyundai are replacing engines with little investigation way past their 10 year powertrain warranty. The other brands are not nearly so cooperative much past warranty expiration that is much sooner.
Ex-Kia mechanic I talked to before buying a 1.6 CRDi said that if I changed the oil every 10-12k miles instead of the 20k in the book I'd be very unlucky to have a failure. He said that pretty much all the common faults on them were caused by oil sludge buildup, including timing chain issues, because they use hydraulic chain tensioners driven by oil pressure. He also suggested using a good flushing oil about every third or fourth service. I would guess that the chain driven gas engines would probably benefit from a similar routine, ie- more frequent changes and an occasional flush.
That sounds logical.
At Finland most car "guides" recomend oil change around 10-15k km, and some cars have maintenance only at 20-30k km. Interval
10k miles is 16k km, so even 10k miles exchange rate is kind of long compared to what is seen as standard at here.
Oil change is pretty cheap, so it is cheaper to do every 10k km/ 6-7k miles than replace thr engibe.
20k miles is 32k km, and if someone would sell car with that long oil change interval, most buyers would be really suspicious here, as it is way too long in our eyes
@@Haawser My kona N has a change interval of 8k miles and I am not going anywhere near that.I do not know why KIA gives such long extensions on oil changes.BTW a tech reported on the forum literally every car that caught fire had gone a long time without an oil change.Also In the united states we have 6 months of decently hot to very hot weather and hot weather and turbo cars--esepcially in stop and go traffic destroy oil.
We had a 2015 Kia Sorento with the gdi 4cyl my wife always had it maintained by the Kia dealership every 4k and at 70hk it siezed up, Kia tried to play that lack of maintenance and charge us 7k for the motor after research and they opened our maintained motor that had no sludge they covered the whole motor. It is 100% a design flaw. I recently did some HVAC maintenance at our local KIA dealership and there still having engines fail with low miles now the V6 engines are have an overheating issue. Yes they are covering the failures and yes the cars are extremely nice for what you pay. But they need to redesign the engines. I will say the gdi turbo 4cyl is usually lack of maintenance
@@rollandsaxton Had a friend of mines just had the engine replaced last year on his 2014 Sonata 2.4, no turbo. Engine light was flashing and code was for knock sensor. He took it in to Hyundai and they found the bottom end to be shot. Oil change was done at 3,500miles. He got a brand new motor. Happy guy. Only 46k miles O_O
Looking forward to part 2. Well done as always.

The best mechanic on YT, period! Glad you are back posting mechanical videos.
Not the best mechanic at all. I'd trust an Autozone parking lot mechanic over him. Bad timing doesn't cause a loss of compression, bad piston rings or other issues with the piston/cylinder walls do. Also as @BenzTech said the "small amount of compression" that he "felt" was definitely the cam lobes interacting with the lifters in the head.
You've obviously never watched South Main Autos channel.
I believe these trouble started soon after Hyundai decided they wanted to make their cars more like the Germans. I guess they really did

Question:
If you were to buy or can suggest a "most reliable car/truck" to purchase.
New or Used?
What would it be? If there is such a model and motor and transmission.
Meaning I want to have it all maintained 100% and safe driving, good mpg and cost effective comfortable and where I can put on many miles per year. And just drive and drive.
I am tired of new vehicles with monthly payments, insurance and vehicles that need constant weekly detailing and cleaning all the time.
I just want 100% reliable transportation to and from each day and not worry about breakdowns and high repair costs.
I know there are a lot of variables out there and nothing is 100%
Just curious on your thoughts.
Thanks for your videos!
Glad to see your new content. Made my day. 🙏
I don’t think any modern engine can go without proper maintenance any more. Particularly oil changes are critical. Hyundai did produce some bum engines though. I’ve got the 2.0 in my Kia and I do 5000 miles full synthetic oil changes. Interestingly, Kia sent out a recommendation for 3750 mile changes but didn’t specify for what type of oil. The factory service agent I called seemed to not know the difference.
I have a Hyundai I30N Performance with a 2.0 litre Turbo Theta II GDI engine in the U.K and have had no problems with it, here in the U.K the Theta II engine is a very reliable engine. I know a the owner of a taxi company and his two Hyundai's on his fleet with a Theta II engine one has done 279,000 miles and the other is on 207,000 miles but he is fastidious about changing the engine oil every 6,000 miles without fail.

Good to see you back
Good video and information that wasn't known about these engines
The sad thing with these engines is that they were originally making the 3.3L V6 Lamda II engines and the Theta engines at the Montgomery engine shop, for use in Sonata, Sorento, Santa Fe, etc. But they had enough issues with the 3.3L they decided nope we are gonna stop making that V6 and focus entirely on the Theta 2. And then those sucked worse. The Montgomery engine plant was just a disaster house, not entirely all their fault. The designs were bad. I'm on my third vehicle with a Lamda II V6 and I actually like this engine. Shrug.
We have a 2020 Kia Sorrento EX-V6 Sport (last year for the V6 in the Sorrento) we love, love, love this SUV and especially the engine. 35,000 miles currently no problems.
We had one of these. It handled like a cruise ship and was comically unstable. Gearbox (manual) went after 100k km.

149K miles on my 2011 2.4L... going strong and smooth. 3500 miles OCI since new on the dealer's advice (I'm in a what is considered "extreme conditions" area). But I doubt it will remain this way to 200K miles like my 2000 4cyl Accord did (let it go when the transmission started acting up... but the engine was perfect)
Yep. Just change the oil often and they'll be fine. I'm not a fan of these 15k mile or once a year oil change intervals. They recommend that in my Mercedes Benz but I still change the oil every 5k miles versus that 15k crap.
@JaretKade Agreed I run a catch can on our 2020 Tucson 37,000 miles still runs better than new also absolutely no oil burn off . The dealership uses 5w-20 Quaker state,I change myself now and use 5w-20 Pennzoil platinum as it was the only one Available it is a world of difference from the Quaker state especially in this Florida heat. 4,000 miles interval . That Quaker state looked like water at 5,000 miles still protecting but didn’t trust it, so far I’ve gone I think 2,500 miles on the pennzoil and it’s still holding up nicely with mostly city driving.
One question. what mileage is considered ‘normal’ for a passenger car in your area? here in korea if the car reached 125k miles, we deemed it as almost the end of the car’s lifespan.
@@powershin12 That’s just getting started in the US. Because North America in general is so large it’s not uncommon to acquire high mileage on a car/truck pretty fast especially if they drive for work or live in a rural area. I work at a dealership and we regularly take cars on trade with 250k or more miles on it and most run nicely if maintained.

2012 Hyundai santa fe crdi, runs smooth. Been well taken care of during its 201000km. Its how you take care of the car is the secret
Reading all of the comments, I guess I am really lucky? I have a 2013 Hyundai Sonata GLS 2.4. It is 215k miles. I bought it brand new. The only issue I ever had as the transmission coolant sensor, which was covered under warranty at 92k mikes. Other than that, no other issues at all. I do oil change at every 15k mikes with Mobil 1 and changed out the oil filter at every 7,500 miles. It has been working out for me so I am just sticking to the same routine.
I just got a, 2023 Hyundai Sonata N-Line 2.5l turbo and I couldn't care less about engine problems as the warranty is, 10 year/100k mile warranty. Lol. So....I don't care if anything fails....I get it fixed/replaced for free. Ha also....I ALWAYS change the oil on a new car after the first 500 miles. Some engines just don't last as long as others. It happens....not a single engine and or car maker has an engine that has never had a issue or issues. Millions are sold and odds are, some will have issues, especially with some people driving em hard as all hell and not doing proper maintenance. Again, new hyundais now have a 10 year/100k mile powertrain warranty. So, couldn't careless about issues. Lol also, when buying a new hyundai, you can purchase a lifetime pwertrain warranty for around 2k.....so.....couldn't careless about issues.
I have an 07 Sonata V6 with 213k miles. Still going strong!!

My mom had the turbo sonata...90k miles and it spun at least one bearing...maybe 2. It could idle but that was it. I had blown a volvo 850...my error, but even though it spun a bearing and had bad rod knock, it drove a total of 30 miles before it finally locked up.

2010 Sonata 2.4l Theta I engine @ 70.000 Miles no problems with engine or tranny ever so far. Oilchange every 3.500 miles with normal oil. Runs like new! Alternator went @ 60k or so but they seem to be a problem anyways, but cheap to replace. Good thing we opted for the "last years body/engine type in January 2010, we even got a great deal because the new models were just arriving at the stealerships and they wanted to get rid of this old style model 😄. Best decision/purchase ever!
Check the camshaft phaser too, they are known to be a trouble spot on Hyundai/KIAs. Good luck.
I’ve been building engines for 40 years. The failure that this one experienced is not a Hyundai problem, this is a previous owner negligence problem.
My friend is a service manager at a large So CA Kia dealer. These motors are replaced regularly, even with regular maintenance. It's a known problem with the Hyundai/Kia engines. He bought a Honda for his kid.
@@tvdinner325 The problem is that people today don’t even know what “regular maintenance“ is. Most owners manuals these days suggest running 10,000 miles between oil changes. All that is is a marketing tool. If people think they can get 10,000 miles out of an oil change then they think it’s going to save the money. It’s all a scam.
@@tvdinner325 The fact that this engine made it 108,000 miles before this happened tells me that it’s not a design problem. I have no doubt in my mind had it had more frequent oil changes that this would’ve never happened.
Have you ever seen a 17-18 yrs old drive one of these?
The i30 diesel that I bought, from a dealer had a handful of receipts in the glovebox from the previous owner. This lemon had manufacture/faulty parts problem, but the company would not admit it.
Clearly this guy knows his way around engines. Fun channel. Best car I ever had was a 1991 Hyundai that had a Mitsubishi engine and 5 speed.
Good luck with you new shop you will do good you will get lots of subscriber's. Because you all was have good videos from long time a go. till then have good one
Over the last 12 years all our cars were Hyundai's. IX35, Grand i10, i10, Atoz. Secret is change the oil at 5000 miles. Air filters and cabin filters at 10000 miles is fine. Never had a problem with any of them. They are all going strong. Ee also have a 1993 Camry. Gets oil changed every 3000 miles.
How come i had a forte that had 200K on it before i sold it, and was still running great, and i presently have 2 Kia Borrego with over 250K on each of them, one of them i bought 11 years ago, and there are still running like a champ and don't burn any oil, they have been Toyota like reliable.
Borregos are built like tanks and your Forte was probably well maintained.
Hey bro I've been a huge fan since about 2016. Glad to see you still doing what you love. Hey man idk what part of California your ship is in but I could really use your help I have 2007 honda accord and it's got some issues. Nothing with engine thank god or the trans. Please let me know if you can help me out.
Hi Nefi, unfortunately I can't work on customer cars right now. sorry
I would guess He's somewhere in East San Diego county , i hope he replies cause id like to know as well.
Neglected oil changes will cause the oil to loose its cooling and lubricity and burn up the plastic timing change guides causing a loss of tension on the timing chain. This damage was strickly owner caused. I bought a new 2012 elantra limited in September 2011. Changed the oil every 4 to 5k. Changed plugs at 75k and normal filter changes. Sold it at 120k. Never burned a drop of oil and ran like a top. Now you want to talk about a crap car. Bought a 2006 chevy aveo in oct 2005. Ran it for 14 years and 175k miles. Changed oil every 3 to 4k. Never burned a drop of oil. Only reason I got rid of it was because it was rotting out from our winter salt. If an aveo can go this long, hyundais will if maintained properly.
I have a 2007 sonata with a 3.3 v6 and a 2008 sonata with a 2.4 v4. 07 has 190k and the 08 has 230k. Both cars have had zero engine issues, very minor other issues, and the engines just purr on the highway. No transmission issues either. Proper maintenance, that's it.
I also have a 2007 Sonata, 2.4l auto. It developed a rod knock on #2. Dropped the pan and oil pump/balancer. Removed all con rod bearings, cleaned, scraped and flushed out all oil passages, polished and checked crank, installed new con rod bearings. Checked all main bearings. Buttoned it all up. Have added almost 100,000kms since, still strong. Total cost - $284.00.
V6 are awesome I’ve seen many at 350 k with no oil changes 😂
19 years and 200,000 miles and still running fine!
Had a 2000 Hyundai Elantra drove it 12 years till I hit a deer going 60 totaled the car. But zero issues not a bad car at all.
Friend had a 2009 sonata sold it last year again zero issues. I do believe around 2010 with direct injection they started having all kinds of problems.
Congratulations 🎉 man for your one million subscribers, I'm one of them.
Probably ten years ago, Hyundai/Kia came out with a TSB regarding aftermarket oil filters. It said some aftermarket spin-on oil filters would not flow oil properly when used on Hyundai/Kia engines. This would result in oil starvation issues with the engine. It was recommended that Hyundai/Kia oil filters only be used. I know this was a big issue for many years and Hyundai/Kia did little to inform customers about this issue.
The engines are junk. Oil filters didn't cause the problems.
Common spin-on oil filters have an internal bypass valve in case the paper element gets clogged. If the element was clogged with metallic bits, then the bypass will open and oil with metallic bits will flow throughout the entire engine, and of course that is bad for the rod bearings, which have a very tight clearance and require clean oil to flow.
Not all of them were bad. I work with a lady who has a Sportage with 250k miles zero problems
Strippers and Blow. Love it and Congratulations!
Thank You for this VIDEO!!
Hyundai's likes other brands have good and bad models and good and bad years. I bought used a Santa Fe 2008 3.3 and a Veracruz 2007 3.8 and are strong, reliable, comfy and fun to drive. If you keep doing normal DiY maintenance and know their flaws the car last. Of course are not the best but are pretty awesome for the price. The thing about Hyundai's they improve with failure faster than other brands but struggling because they trying to keep price low increasing performance. If you want the best on reliability Toyota/Lexus should be you aiming... but the price 😬
yes you have to do research on the model within a brand. cheers
Agree 100%. I think a lot of the comments are just from people reading the worst case scenario stories.
I’ve gone 315k miles on a 3.8 and it’s still going.
Chain stretch was common on these, fix is to replace with a upgraded 2012 timing set.
Oh, boy, does this ever bring back memories!
Looking forward to next instalment...
My parents have a 2015 kia Soul with 220k miles and have never had any issues other than a dead battery. It was part of the motor recall but the dealer said the motor wasn’t effected.
My Hyundai Santa Fe just hit 300,000 Miles yesterday. Still going strong. You need to change gear and oil change makes very big differences. I see many drivers don't change gear. Especially Ferarri drivers.
Dont tell me your Santa Fe has the Theta II engine
Yep. When my kia was still under warranty and had about 50000 km on it, I asked the kia service people to change the gearbox oil and stick some new spark plugs in it, as wellas the normal service. Guy looked at me as if I was crazy. He eventually said ok. Haha. Strange times we live in...
Well, not all hyundai engines are junk, thats for sure. I have a 2009 Azera with the 3.8 v6 and its the quietest, smoothest engine Ive ever had. Over 160,000 miles - nearly perfect car.
I have a Santa Fe with the 3.3 V6 Lambda. It has 160,000 with no issues. I have heard things about the 2.0 though. Keep us posted.
I got a 2018 in December. It has less than 7k miles on it and has been back twice for dropping to limp mode from a knock sensor code. That's once before they changed the sensor and once after. The car can't handle rpm load when passing or merging onto the highway. Both times the car dropped to 40mph almost immediately, almost causing pileups. DO NOT BUY A THETA II EQUIPED HYUNDAI OR KIA.
I'm 63 years old. The only engine failure I've ever had was an 07 Silverado that looked great, had 93K miles on it when purchased, but was purchased with a title indicating true mails unknown. At 104K miles engine would not develop any oil pressure. After a new oil pump with still no oil pressure a rebuilt used engine was installed with a new oil pump. I am convinced that this truck was a company truck because of a sticker placed on the door jam with 6 numbers indicating it was a fleet vehicle. Bottom line? The money that I saved purchasing it originally was spent with the engine install.
I know that these engines from Hyundai have had issues just like the lifter issue with GM in the 5.3's and 6.2's. I think that in most cases if the owner takes care of them and changes the oil at 5K or once per year they are fairly reliable. Not a fan of GDI engines but that is my personal preference. 10K or 15K mile oil change intervals is insane in any gasser IMHO.
My mom just traded her 2017 Santa Fe sport because it burned 2 Quarts every 1.5k miles. Only had 80k miles. It was ridiculous. She got a 2019 rav 4 with 17k miles. I’m happy she listened to me and got a Toyota.
Did you take a true oil pressure reading with a test guage ?? GM V8 engines in the late 2000's to mid 2010's had issues with the oil pressure guage on the dash. You may have replaced the engine unnecessarily.
@@charleskosyjana1295 Yes. Two different mechanics. No oil pressure. Finally put in a new oil pump. Still no pressure. Purchased a used unit with verified 90k miles and installed the new oil pump in it.
My 2010 Sonata with the 2.4 engine has been a great car. The one thing to be carefull with is the oil filler cap is located in a recess. Sand and road debris collects in the recess. I always blow the cap off with compressed air before opening. If you don't do this the sand will fall onto the #1 cylinder valves and timing chain.
I just turbo’d an old 99 Elantra. I took it out on its first little rip only on 5psi and broke the transmission 😂
Ive got another one on the way. Hopefully I have better luck with this transmission.
Encouraging that Hyundai came clean and honored their warranty. GM would still be fighting with customers and chiseling everyone. A fast look w/ a borescope would be nice.
My 2005 Hyundai Tuscon GLS has 143,000 miles on it and I have never had engine problems with it. Still drives like new.
I came across a 2012 sonata at a job I was doing and I asked the customer what happened to it and he said it just died on him while driving it.he said his mechanic told him his engine blew out. I kinda expected fluids and didn’t see any oil coolant mixture . The car was in good condition interior and exterior so I asked how much and I believe it had 135,000 miles , he said $1,000 but after researching those engines had recalls and was past warranty, so I passed on it
My 2013 Kia Optima 2 lt Turbo had a recall and they put a new computer chip in at about 190,000 km. They guaranteed me that if I had any engine issues it would be covered. Sure enough about 20k later the engine went out in a very rural area in the mountains of BC. I called the nearest dealer and they advised me I was
"Covered". In the end they paid $500 for vehicle recovery, supplied me with a U Drive and put in a factory new engine... all at no charge. I use full synthetic oil and change at about 5000 km as Turbo oil lines can clog with dirty oil. I now have
220,000 km and it runs great. I will watch Turbo as it's original .
I just got a, 2023 Hyundai Sonata N-Line 2.5l turbo and I couldn't care less about engine problems as the warranty is, 10 year/100k mile warranty. Lol. So....I don't care if anything fails....I get it fixed/replaced for free. Ha
Smart man. Although if you are a scrap metal recycler, it may have been worth the $1000🤔
@@DavidMScott-cs8pp And I believe you....😂
My 2013 Hyundai Santa Fe with 3.3 died at 99,000 Miles. I can't even get a Hyundai dealership to find out exactly problem, they don't do engine work anymore. They say it might be a bearing.
They will be glad replace the engine for about 10,000$
Awesome Dude !
As a kia master mechanic for 8+ years I have never seen a timing chain issue. Please show us the bottom end rebuild as we never do that at the shop. Only short blocks

I own a 2010 forte sx with the theta 2.4L. It was hands-down a build quality issue. Then when you mix in lack of maintenance 🤦♂️…I am technically on the 3rd engine during my ownership. First one was in the car at 175k, drove it home with a bottom end knock. 2nd engine had a bad wrist pin and luckily was warrantied out. The current engine has been good but was low mileage at 63k out of a totaled koup. These engines are poop. And they’re in so many vehicles….it’s a damn shame

@@goffthomas2554 wrist pin essentially holds the piston and the conn rod together
@@Noahinthe802 Good after noon Sir! Yes as I said it is a gudgeon pin! I was Rolls Royce trained apprentice, 50 years in the motor trade have never heard a gudgeon pin called a wrist pin. Different expressions for different parts in other countries! We call fuel petrol you cal it gas.

@@Noahinthe802 thank you for your reply, so many American terms different to ours. I have learnt from this, take it easy buddy good to talk. 🙂
The “small amount of compression” you think you feel is simply the camshaft lobe resistance as the lobes move the valves.
he's and experienced mechanic. im sure your calibrated eyeballs are superior
I have a 2.4 L Hyundai Tucson. There is a recall on the engine in mine (2019) that suspected there was an oiling issue during crankshaft milling at the factory. I do mostly highway driving and the dealership mechanic told me that if there were a problem, I probably would not see it...stop and go ?...perhaps.
I drove my 2005 Hyundai Elantra until it had 265k miles until recently. I bought it brand new for $12k back in 2005. I sold it cheap. There was nothing wrong with with it. I took care of it. Great reliable car. I did MAINTENANCE on it, and that's why it lasted.
Mostly because people dont change the oil in half the time the manufacturer says. Those numbers are for perfect conditions. I would cut the interval by 30-50% to play it safe. So if your manucacturer gives you a 10k mile interval. You should change it in about 6k
The thing is, the manufacturer does give the right intervals for maintenance. It’s under the “severe” maintenance schedule, it’s owners not fully understanding the owners manual maintenance section.
@@BeyondLumination Yeah. Most people assume they aren't doing severe driving. But I always follow the severe driving plan. It seems to have helped the most to stay ahead of issues.
@@TheoriginalBMT yeah i have always followed the severe interval myself. Even though i drive about 75%highway and 25% city in mostly mild weather. It does get times where it is really humid out and the winters get a little extra salty. But other than that MD is pretty chill climate.
Ideal condition is like 95% highway driving. Severe is like 70% city miles or higher. I usually change every 5k with full synthetic.
@@2010ngojo yeah i do mine every 4k and do all my transmission, diffs and brake fluid every 3 changes
The Theta 2s that have the oil starvation problem are the ones built in the U.S.; the GenCoupé was manufactured in Korea. Nevertheless, my GenCoupé gets Pennzoil Platinum High Mileage 5w30 and a dealer filter every 6000Km (3500 miles), per Hyundai’s maintenance schedule, and never further. My short experience as a service advisor at a Hyundai dealership taught me that stretching maintenance intervals leads to expensive problems. Oil is cheaper than engines!
Awesome video
It's not oil changes, people have been documented that they changed oil every 3,000 miles and Kia/Hyundai engines still blew up at pretty low mileage.
Any engine that blows up before 300,000 miles is crap.
