The engine only has 78K miles on it. I took it in because I received a notification that said stabilitrack. First I had a mechanic change the spark plugs, then I was told I had to take it in for a bigger issue with the engine. I was told it would cost $2500 just to break down the engine and diagnose it. Then I was quoted 11k on top of that to completely replace the engine. 78k miles and the engine needs replacing for more then the car is worth. The diagnosis was that I had a piston crack and the whole engine was ruined.

What component or system failed or malfunctioned, and is it available for inspection upon request" The engine oil pressure control circuit is stuck. How was your safety or the safety of others put at risk? I was driving when all of a sudden my car would not let me speed up to the speed limit and almost caused someone to rear end me. Has the problem been reproduced or confirmed by a dealer or independent service center? Dick Allen's in Meadville as well as AutoZone who read the code Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No warning until the light came on and the car slowed down. This is the 3rd time this has happened. Previously I was told to put Cataclean into my fuel to help which it did but it seems to only be a temporary solution.

I was driving down the interstate when all of a sudden my information center on my was driving down the interstate when all of a sudden my information center on my 2016 Chevy Malibu popped up a warning, reduced engine power and drop me down to 20 mph without warning. I barely made it to the side of the road before being run over by 18 wheelers all around me. Once I got it home I read the code, and it shows there-??s not enough power going to the turbo in the engine that-??s caused by the accelerator sensor. When I start at low speed or from a stop in attempt to accelerate the car hesitates to the point I can-??t pull out with any cars around because I will be hit. I-??ve been told this is a known problem for the vehicle and it-??s a $500 part to fix. It-??s extremely dangerous and I am so shocked there has not been a recall for this, it is putting everybody that is in one of these vehicles in danger

automatic transmission shifter assembly is out of specifications and needed to be replaced by removing the center console to gain access with all other related new seals gaskets and non-reusable hardware and reinstall all components for repairs in the reverse order of removal. cleared all diagnostic trouble codes. the system is NOW operating as designed. Before the repair was made the car kept telling me that the shift was NOT in park, when it was. I am uncertain as to my safety or risk but was afraid to drive the vehicle as is. The repair was made on 8/17/23 by Richard Lucas Chevy, 1077 Rt.1 S, Avenel, NJ 07001 732-634-0100 at the cost to me of $435.42. My claim with GM is #9-10454143101. I was notified that this was a common problem with my specific vehicle and yet there has been no recall.

I bought the car brand new. Periodically the doors will not lock or unlock, only one at a time. I have had it in the shop on numerous occasions to get it repaired. It's fine for a while then it does it again, it changes from door to door. Now I can not get the driver's side back door to lock. My dash lights up to let me know the door is unlocked. I am afraid when i go to a public place, that someone will get into my car. I am so aggervated with this. I have an appointment AGAIN with the dealership for 8/16/23 for them to look at it and try to solve the problem. I have no idea when this started as it's been ongoing. The dealership is Wantz Chevrolet in Taneytown

In November 2022 my vehicle (2016 Chevrolet Malibu) experienced a vacuum pump failure resulting in the brake system being inactive. Once the brake pedal was pressed, it remained locked and further stopping was not possible. Luckily I wads able to stop onto the shoulder, however it was on a busy highway where I was nearly unable to stop as we were merging from an exit ramp with no emergency area. Both myself and my girlfriend safety were at risk of injury had we not been able to safely pull over. After being towed to an auto repair shop the vacuum pump was replaced with no issues experience until 4/2/2023. As of April 2023 this same error occurred once again after entering a busy area. A second time I was lucky enough to have been away from traffic, however it could have resulted in personal injury or the injury of another individual had I not been able to pull off into an emergency lane. The car has since been towed to a certified Chevrolet dealership where I am awaiting an estimate on repairs. Initial review from the mechanics state damage has been done to the brake boosters as well as to the cars cam. Estimates on repairs could be as high as $5,000 or more including labor, diagnostics, and parts. Prior repairs done in November were nearly $700

I-€™ve noticed this issue a couple weeks ago but now since it-€™s been constantly raining I-€™m having water inside my car every single day.

Numerous times my vehicle has not allowed me to shut it off, start it, or move the vehicle because it says that the vehicle is not in park when it very clearly is. I googled the issue and found that numerous other owners have had this issue, and the tech advisor at the dealer confirmed numerous people have had this issue as well. The issue was a faulty switch in the transmission control. 2 different major safety concerns resulted because of this. First, I was unable to start my car in a very bad neighborhood for over a half hour because it kept saying shift to park to start vehicle. Second, I could not shut the car off while parked in the garage because it said shift to park to shut off the vehicle. Both times I was fully in park. This problem is widespread as a simple google search will confirm, however, GM continues to deny it is a problem.

I have had several issues with my 2016 Malibu. 1st: Putting my vehicle in park sometimes it does not register that it is in park. I have to turn the car on again and try moving the shifter until it registers. 2nd: when accelerating at times i get a stabilitrak error and a check engine light that causes a loss of power. This can happen in the middle of the highway which will cause an inevitable accident. 3rd: saving the best for last. Thw vehicle has recently lost power while driving and won't allow acceleration. Once i stop the vehicle stalls out completely and won't register the gears so i can't out it into park or anything. I was stuck at an intersection and couldn't move. It wouldn't turn fully off because it didn't register it was in park. And it won't turn on or start because it isn't on or off. I maintain my vehicles and correct all fixes recommended. Brought it in to have the issue looked at and was told that there were A LOT of error codes. They cleared them. But this has gotten ridiculous. GM needs to figure their stuff out..

- Houston, TX, USA

When I was driving to work, a light appeared on my dashboard stating that my "Engine Power Reduced". When I was in the left lane passing a vehicle, my car slowed down to 40pmh instead of accelerating when I had pressed the gas pedal. The car behind me almost re ended me in the process. This has happened now on a couple of occasions afterwards.

All of a sudden my Pistons just went in my car the whole engine block actually. There was never any warning or anything I got an oil change and after the oil change the check engine light came on plus it said service stabilitrak. Without the stability track you can get into an accident because the car is not in control the way it's supposed to be. The Pistons being worn in the engine block going. Without any notice of anything being wrong. Causes bad emissions leaks etc. The dealership knows about it. They can't give me a reason why the Pistons and the engine block went. Or why this service to stabilitrak came on. They're trying to say it's a pipe that has a dent in it. But the entire system is rotted out it only has 34,418 mi on it.

Reduced engine power on my display for the 3rd time since I purchased the vehicle. This is ridiculous and needs to be addressed. Good thing it never happened on a highway.

My 2016 Chevy Malibu Premier continues to show a -€œShift to Park" message-€ even when I put the car in park! When this -€œShift to Park" Message-€ is on, I cannot turn off the vehicle. In order for the message to go off, I have to either back up, or pull the car forward a little in order to make the message goes off. This is starting to happen daily with this car. This is very frustrating.
