The TRUTH About Auto Stop-Start System (Nobody Talks About)
Learn why auto start-stop systems in modern vehicles are causing serious concerns among professional mechanics and vehicle owners. In this comprehensive guide, you'll discover the hidden costs and potential damage these fuel-saving features can inflict on your engine, starter, and battery.
A start-stop system is a feature in modern cars that automatically shuts off your engine when you're fully stopped - like at a red light or in traffic - and then fires it back up when you're ready to move. Think of it like your car taking a quick power nap to save gas whenever you're not moving.
The engine turns off when you hold the brake, and springs back to life when you let off the brake or hit the gas. It's supposed to help with fuel economy and emissions, especially in city driving where you do a lot of stopping and starting. To handle all this starting and stopping, these cars need beefier starters and special batteries, which is where some of the problems start coming in.

    I bought a 2014 Civic LX for $6000 cash with a CVT. Car could barely move when cold. A week later, watching TH-cam, I learned that the transmission plug might have fallen out and all the fuild poured out because of a clogged breather valve. YUP. Cleaned out the breather hose; then I ordered 8 quarts of Honda CVT oil, a new plug and put in 1 quart of trans oil. Civic ran great then after I added the one quart. Then I got the new oil, plug and found the old plug sitting on top of the transmission; just like the TH-cam video said it would be (WOW)! I drained the transmission and found there was only one quart of oil? That was the quart I put in a week ago. Refilled the trans til it came out the check oil level hole and that was that. I called the used car lot and told them the car was running great!! He paused for a moment and replied: "How is that possible?" So I told him. He was very mad and slammed the phone down and hung up on me. He sold me a lemon - for a third of its value. I'm just saying.

    The third method describes doing something different than what's shown, which makes it confusing. Do we depress the brake pedal or not? The verbal instructions don't mention the brake pedal. I hope something works on my '20 Impreza. Feels like it's dipping into a hole in "second" and have to give it more gas, and I've lost like 3mpg over the last couple months. It wants to stay at lower RPMs all the time and doesn't want to downshift unless you step on it.

    unfortunately, some manufacturers (Audi for one in 2025) no longer allow the car driver to turn the start/stop off. Others require the star/stop to default to on every time the engine is turned off. So the driver has to hit the button to turn it off each time he/she starts the engine. So if start/stop is bad for that Audi turbo engine, will Audi cover the engine failure under warranty after the warranty expires? I think not.

    Another option which was working for our Hyundai Santa Fe 2024 MY25 it was to inflate the tire with the engine running and watching at the TPMS screen. For the tires which were showing pressure with yellow fonts, we inflate at 37psi and it became white. We have used 37 psi as the petrol station was maybe 2km away from home and the other 2 tires were hot. TPMS alarm was gone and also the Service alarm. After I reached my destination and let the car rest for 2 h, when I restarted the car, tire pressure was 35. Which is the recommended pressure for my 21R tires. Problem solved and lesson learned!

    In March 2013, I bought a 2003 Odyssey with a broken motor and a full tank of gas. I didn't get around to fixing it until September 2016. I drove it for weeks and when it got close to empty, I started carrying a gas can with me so I would have something to put in when it completely ran out of gas as I didn't want to mix the old gas with new. It ran PERFECTLY on that 42-month old gas. PERFECTLY. I'm not saying that gas will last indefinitely, but I can tell you that it will last at least 3-1/2 years.

  • @claiborneeastjr4129

    There's a lot of controversy about changing ATF or not at all. It seems the consensus is that, if you plan to change it, do so about every 60K miles - or don't change it at all. Also, consensus seems to be do NOT flush the trans. A family member has an F-150 with 440,000 miles, and the ATF has never been changed. It still shifts normally. Also, check tire pressures cold. As far as engine oil, I would never exceed 5000 miles. No engine ever suffered from too-frequent oil and filter changes. It's cheap insurance.
