What 268 owners told NHTSA about the 2015 Chevrolet Malibu Eco

have a 2015 Chevy Malibu that is randomly trying to start itself. The key fob is the original when I bought it. It has the auto start on the fob but is the kind that requires the key in the ignition to drive.car completely off (not in aux) but the key is in ignition, could be for 2 minutes or hours, and randomly it will try and start, but not fully turn the engine and actually start, just that little half second of a start and then go right back off. Today it did it 3 times in a row. Obviously I won’t be leaving my key in the ignition any longer as it does seem to require that,

When driving at highway speeds the car will show “Engine reduced power” and will either drop to 20-40 mph or shut off completely. Engine codes show as cam shaft sensor, crankshaft sensor and fuel pressure regulator. I had the cam shag and crank shaft sensors replaced and it stopped for a few months. It started doing it again this week and today it did it then shut off completely and won’t restart

There is an electrical issue with the vehicle, causing bad computer readings related to the O2 sensor, VVT valve/rocker arm solenoid. It causes shaking and bad acceleration. These parts were already replaced and within days of the “repair”, I am still having issues. If driving and I start to accelerate, it gets shaky and almost stalls the vehicle completely. If that were to happen while driving in the middle of the road then that could easily cause a wreck.

When it rains the driver side fills up inside with water causing a puddle behind the driver in the rear of the car. This causes mold inside the car and also creates condensation while driving. I googled it and many blogs have been discussing the problem. I brought it to 2 different shops and the air vents were blown out to no avail. I also called the dealer and they were not aware of any problems. I have allergies and this makes my car trigger attacks.

When I come to a stop my auto stop engages and when i accelerate to continue driving my car won’t turn back on and stays dead for up to 20 minutes. I have almost been rear ended numerous times. It does this every single time. So now when I’m coming to a stop I put it in neutral before being at a complete stop.

On multiple occasions since July of 2022 my vehicle has had a reduced engine power warning and caused dangerous situation where the speed limit was 70 and I couldn’t go over 25 and I was miles from an exit. Took it in had throttle body replaced, and it happened again. Took it in again replaced the gas pedal position sensor. Happened again replaced the throttle body again and this time we broke down in Nashville on our way to Florida. Then 10 miles away from Nashville same issue. I took it to the nearest dealer and here I wait, thousands of dollars into it and not knowing how to proceed.

I bought my 2015 Chevy Malibu in 2016 at 36k miles. No wrecks, 1 owner before myself. No warning lights on when driving from the lot and the car was just what I wanted… tho always a little doubtful because it was pre owned 1) there was always this random, unusual, indescribable smell from the vents where I couldn’t breathe but no one else could smell or experience it. I just kept getting sick. 2) I thought “MY” first 30k miles or so was rolling too fast and 3-5 months in, the ENGINE light popped on. Immediately took it to Chevy who said my engine light was on due to an “airbag” but wouldn’t tell me which unless I paid 70$. 3) Still, driving was not affected so I kept taking it to the Chevy dealer every 3-6 months for the proper maintenance. About 2 years in I go for an oil change at CHEVY: one guy pours RADIATOR fluid in my OIL compartment during the oil change. Just before he realizes it’s the wrong thing and looks to see if I saw, I alert the manager who immediately drains the oil and says it won’t be affected.. and assures me everything is fine. ??? 4) 4 years ownership, the service stability track message started appearing and the ENGINE POWER REDUCED SPEED LIMITED TO 25 MPH starts popping up on the screen and simultaneously the car DANGEROUSLY goes from highway speed to 25mph. ONLY Jesus mercy! That’s a death trap in itself. Still no recalls and no help. Temp fix (get to safety, turn off vehicle, wait 30 sec-1 min and restart) 5) At 150k miles, I returned to get transmission flush.change.check whatever the best procedure was. Chevy says, I wouldn’t because it doesn’t have to be serviced on these vehicle. yet they send me coupons for trans services. 6)JUST put on new tires, oil, oil cabin, and engine filters changed. Car riding smoothly then 4 days later I start it and up pops a message about SERVICE POWER STEERING: drive with care! No Gearshift lights. And it’s an EPS system! Something is WRONG with these cars. 7) Paint defects along pass. side

I was almost to work on the highway and my car dashboard said Engine Power is Reduced. It quickly started powering down from 74 directly to 50 then 40, then 35 and finally to 26 before I could safely pull off to the side of the road. This issue is getting worse it takes at least 10 minutes of waiting and turning my car off and on before it is back to normal. Others have said that they have gone to the garage and had it replaced and it just continues to happen. This needs to be a recall and not just a change of parts every few months.

I was driving to Harrisburg, PA on the highway traveling at around 68 mph and my car dashboard said Engine Power is Reduced speed Reduced to 45 mph and it instantly slowed to that speed. Then it counted down very quickly to 35 and then 25 before I could find a safe place to pull off to the side of the road. I turned off my car, waited for a bit and then turned it back on, it still said Engine Power is Reduced, so I turned it back off and waited again. I turned it back on and it still said Engine Power is Reduced so I had to turn it back off again and wait. Sitting along side the road on the highway is not pleasant. I turned it back on and it was fine again.

I was driving back home from Harrisburg, PA on the highway traveling at around 72 mph and my car dashboard said Engine Power is Reduced speed Reduced to 45 mph and it instantly slowed to that speed. It took quite a while to find a place to pull of to the side of the road because of the area I was in. It was quite frightening because everyone else is going the actual speed limit of 70 mph or over. By the time I found a place to pull over my car was reduced to less than 25 mph. As usual, I turned off my car, waited for a bit and then turned it back on, it still said Engine Power is Reduced, so I turned it back off and waited again. I turned it back on and it still said Engine Power is Reduced so I had to turn it back off again and wait. I turned it back on and it was fine again.

I was on the highway traveling at around 68 mph and my car dashboard said Engine Power is Reduced speed Reduced to 45 mph and it instantly slowed to that speed. Fortunately I was able to pull of to the side of the road quickly and I turned off my car, waited for a bit and then turned it back on, it still said Engine Power is Reduced, so I turned it back off and waited again. This was at night, in the dark and it was not a pleasant experience to be pulled to the side of the road with your hazard lights on while traffic just buzzes by and your vehicle is disabled. This happened three times in one day during one trip. It's absolutely ridiculous and numerous other people have the same issue.

My dad was driving my car when the car dashboard said Engine Power is Reduced Speed reduced to 25 mph. He pulled off to the side of the road and turned off my car. He waited for about 2 minutes and turned it back on, but it still said Engine Power is Reduced. He turned it back off and waited for 5 minutes and turned it back on and it was ok again.
