You're the best Jose! Awesome video! I've got to say that although I had a general understanding of everything you spoke of I still can't totally get how the fluid goes into the electric motor, nor how the clutch throw out bearing works in the first place? I just can't picture the insides in a way that makes me understand, but maybe if you have time and you think it would add value you can draw a diagram? That'd help me understand a lot! Thanks again for your awesome content!!!
Take a look at the previous video and you will see the level of flooding inside and the also you will see that in time that more fluid adding the more higher level until it reaches the electric motor shaf that does not have any seal hence fluid will pass through...
@@hybridsolutiondiagnostics I've just watched it and, again: great video!!! (i didn't expect it to be any less!) I understand the leak comes from the clutch slave cylinder components inside the clutch compartment and not from the actuator, and if you see the fluid level dropping in the reservoir and keep filling it up, rather than spilling from the actuator it will accumulate in that space where the slave cylinder sits and eventually reach the slave cylinder itself and therefore the shaft connected to the electric motor, which is not sealed, hence the electric motor may receive clutch fluid. Is it correct? And do we know what exactly is done in the recall to prevent this from happening?
@@hybridsolutiondiagnostics So even though there is a recall, it won't solve the problem long term, right? Cause replacing the slave cylinder without any further upgrade/improvement (eg. seals/gaskets) still leaves the problem liable to occur?
The dealership wants $10,000 to replace it. It’s a $2300 battery with a $2500 core charge, so why double the price? Can’t order a new battery without an RA number from an authorized dealer. So, only option is a used battery. EBAY has a couple for around $1500 plus shipping. I’m going to check the 12v battery first though. I don’t trust that the dealership actually checked anything for the $170 fee to inspect. The hardware doesn’t look like it’s been touched, so asides from putting the key in and saving “yes, it’s dead” , I think they greedily want to sell a new car… 🤔
@@DKTek0710k is too much, you can get it online for around $2k and install it yourself if you have time and not mechanically challenged. But yeah, check the 12v battery first to see if it is good, while you are taking out the battery anyway, also check the main battery see if there are cell that can be salvaged
Hi Firstly thanks for your videos. I have a Hyundai Ioniq Hybrid 2020 unfortunately it jolts or clunks heavily apon moving off from a standstill. Also unfortunately it is an intermittent fault , but as a taxi this happens once or twice a week. It is enough to alarm customers. Any advice welcome . Please
Do you think you could make a video for diagnosing the 2011-16 Kia Optima/Hyundai Sonata issue that starts w/ the Hybrid System Warning on the Dash that directs the driver to pull over park the vehicle for Safety? The reason I ask is because once you turn it off it won't restart w/o some diagnostics which if you bring it to a dealership mechanic 99% they will at a minimum diagnose a faulty Power Relay Assembly & more often than not also tell you your Hybrid Battery Module needs to be replaced as well ($2500 - $6500 for parts & labor) when the truth will almost always lead to the Hybrid Safety Plug 125A/150A Fuse or the even easier & so much cheaper fault of the 12v Battery needing to be charged or replaced (parts & labor $50-$250 @ the most). It would be greatly appreciated & extremely helpful for so many people. Thx 👊🏼
This engine clutch is the weak link in this car on the 3rd gen Prius it’s the pcv that plugs the egr system up and makes head gaskets fail very few independent shops here in the US have the proper software to do the fluid exchange for that engine clutch I will definitely keep an eye on the engine clutch fluid level now
theses cars a ticking time bombs, 3 clutches, thats just more things to fail, It has 4 park up in my area to fix and the owners don't have the cash, theses cars are nice new but it isn't long term vehicles
@@Emdsd45T once a year, but draining and fulling doesn't make sense because the old oil would still be in the actuator chamber, its best to vacuum it out
Hello. I have an Ionic plug in 2018. 75,000 km. In second gear it starts perfectly, but in 2nd gear it slips. Do you think it could be from the actuator ? or something else, I just can't believe that the clutch has to be replaced at these kilometers and I'm looking for the problem somewhere else. Thanks for the nice videos!
I wish the paddle shifters did not have Soo much control over the amount of regen braking I prefer that function be done through the brake pedal instead as it has super smooth modulation.
Thank you - I have a PHEV 2019 Niro - with major issues - (currently under 16k miles) - right afer braking - there is a follow up grinding noise as if some fan propeller brushes/rubs against something on the underside of the car below the driver seat. Further more recently the steering wheel has become harder to turn. The dealer has not fixed the issue - did some recall add on that tends to muffle the sound a bit - however the sound has become more frequent now. On Repeat visit - the Dealer refused to even acknowledge that there is an issue and said it is normal for the car. Will be taking the car to another dealer soon - will update this - if they fix it or might get hold of a local lawyer.

Hello Jose my brother I have ask this essential question from your expertise. I have an engine code right now about clutch actuator P0901 and I don’t know if it’s the only thing need replacement or also my slave cylinder or master cylinder also. I have noticed my engine fluid went out after I smell a burning fowl smell when all of a sudden I step on the gas and rpm was going up and my car wasn’t moving at all but eventually it drives and moves. So should I also replaced my slave or master cylinder when I only have P0901 code of clutch actuator? Thank you in advance.

I am halfway thru my lease on a 2020 Kia Niro and it has had constant issues since around 1,000 miles. I’m now at 12,000 and the car jerks, sputters, feels like it’s going to stall and the check engine light comes on. I have taken it to the dealer multiple times and they keep telling me “that’s just how it drives!” I have a 20 mile commute to work and I’m afraid to drive my car. What do I say to them so that they will fix the issue? This is my first Kia and will definitely be my last.
It seems you're having issues with DCT Module, possibly specifically Engine Clutch and Slave Cylinder. Better have it diagnosed with someone who knows about hybrids and DCT transmission, and have the specific tools to fix it. Mine was presenting the same issues and it turned out this was the problem, however it still is under repairing, hoping this will fix everything.
Good morning, could you help me? I have a 2017 hyundai ioniq. It is giving me problems with the gears, so the 2, 4, 6 does not fit and the retro one, they tell me it is the speed sensor. Can you help me where the sensor is located?
I have 2020 hyundai kona and when the engine is hot (running for 30 mins and more), when accelerating around 2500 HP and 3500 Hp it makes my car sound like race car and its loud even though its a base model. Is this normal? Or is there an issue?

My 2020 Hyundai Kona was at Reliable Hyundai in Springfield Missouri for over 1 1/2 years. It only had 6500 miles on it and under full warranty. The dealership experience was horrible. The excuse, week after week, month after month, was that the couldn’t get approval from Hyundai Customer Care. Only after getting an attorney involved, did they finally take the car back. During that time, they didn’t give me a loaner vehicle. I spent over $16,000 for 1 1/2 years of rental car expenses. I was expecting full reimbursement, but they only reimbursed $4000. What a scam! I finally went down the street and bought a Toyota Camry. I learned a lesson. I hope you avoid what I experienced.
Same as in MX. I only paid for the diagnose and took it to another mechanic that has some knowledge in hybrids and transmissions and bought the spare parts in eBay.
I have a 2012 prius c, the battery is new but when the a/c is on it drains the battery quickly, and cuts off the hybrid system. Error P0A80. Is the a/c compressor bad?
most times with gdi when you getting a rough start then it drives normal is carbin buildup on the intake valves, you can't prevent it, its only a matter of time, you can use a good quality oil and install a catch can in the pvc system, this only slows down the process of the buildup, there is a reason why companies put the intake mainfold in front on cars theses days, so it would be easier to clean the intake valves
Check the injectors. I can’t stress this enough… even if no codes are coming up. The misfires in my ‘19 Niro was blamed on anything from “cost*o” fuel, to short trips, to high winter humidity, to being in the “driest” part of the country. Not until two injectors coded, and warranty replacement was granted 🙄, did the misfire/ rough idle/ black spark plug mystery get solved.
