My vehicle accumulates moisture and has done so for the past three years or more. As a result there was mildew in the vehicle which was covered under the manufactures warranty and the vehicle was cleaned. Now fast forward a few years there-??s a problem with the electrical system as a result of the moisture accumulating in the vehicle. I believe there is a manufacture defect with the Chevrolet model that is causing moisture to accumulate in the vehicle does causing electrical issues with the car

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.

Reduced engine power alert. Ongoing issue since 2019

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..

It is currently an intermittent problem on my 2016 Chevy Malibu with 27,880 miles on it. Once shifting the vehicle into park, the gear selector is indicating the vehicle is in park, but the dash board reads "shift to park" and does not allow you to turn off vehicle, it remains in accessory mode. You do not know if the vehicle is really in park because the dash board warning reads "shift to park". If you try several times to put it in park or jiggle the gear selector, the warning will go out and then you can shut down engine. This is unsafe as you don't know when this happens if your vehicle is really in the "park" mode. If you vehicle is not, it could roll or injure someone standing near the vehicle or it's operator or passengers entering or exiting (if it should move unintendedly). I was informed that this is a known issue This defect should be deemed to have "special coverage" and not be an out of pocket repair and a recall campaign should be initiated as it is a safety related concern.

I was sitting at a stop light and all the sudden my car just died in the middle of the road. I to tried to restart and my brake pedal was very hard to push down and on the dashboard it said Engine Power is Reduced. I was not able to start my car at all and had to be towed. Lights and radio were still working.

When shifting into park a dash message appears saying shift to park. The gearshift is in the park position but the message still appears and some electrical devices remain on and you cannot lock the doors.

1. The car when s parked the electronic system does not recognize this and the electronics of the car remain on. Draining the battery and sometimes taking several attempts or more at having to restart the car, shifting through gears in order to get the car to properly turn off. 2. I have been driving down the highway doing approximately 65-75 mph and the car out of no where, with no other cars around has slammed on the breaks and decreased in speed instantly. This has happened twice. 3. Stabilitrak light has come on several times, car violently shakes while ideling. I have already had to replace a piston in the engine. At the time the car was at about 50,000 miles. It is now at 75, 000 and still happens every so often.

I was driving on the freeway at about 65mph, and the car shut down on me. It was extremely dangerous to get over on the freeway with no power. 2 warning lights came on. The Stabilatrak, & the check engine light. I pulled over & called for help. I had the car taken to the service department at the dealership. They contacted me & informed me that a piston was cracked, & the ECM had to have a software update. They are charging me $5,389 to repair it. The car only has 8,000 miles on it. There are recalls for this exact problem, but do not apply to my specific VIN#. My car is a 2016, so I am out of warranty, but this should not happen with a vehicle with this low of mileage.

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.

When I turn my ignition button off, the dashboard on my vehicle will have the letter P showing that it is in Park, but will have a message pop up on the dash that says "Put in Park". I have to wiggle my transmission lever around while it is in park until it finally clears the message.

I was driving to the clinic I go to everyday in the mornings I was in the freeway going about 70mph when suddenly I get a msg saying -??engine power reduced-?? also engine light came on and the car starts slowing down and it-??s not letting me go more than 20mph on the FREEWAY! I could have caused an accident, (this is very unsafe specially since my 2 and 4 year old were in the car with me) I got off on the next exit and pulled in to a gas station and turned the car off and waited about 10 mins I turned the car back on and the msg was gone but the engine light was still on about a minute or 2 later the msg comes back on so I have to pull over again, it did it about 5x before I can make it to my destination not to mention the way back home I had to stop about 3x more. This is very unsafe and something has to be done as it is not only my car with this problem.

- Sacramento , CA, USA

I can be driving and "drive assistance system" and "engine reduced power" comes up and then the car starts to slow down even on the highway and that is ridicoulous.

- Henderson , NC, USA

I was driving my car home from work and all of a sudden my car starting showing in the dash engine power reduced. My car literally couldn't go anywhere. So I pulled over and shut the car off for a minute started it back up and it was running great and then I happen again a few minutes later. So I took it to the dealership were i purchsed it and they replaced the gas pedal they said a sensor was bad and that was causing the problem.So picked up the car a couple days later and it happen again about two weeks later...

The contact owns a 2016 Chevrolet Malibu. The contact stated that the shift to park warning message would illuminate on the instrument panel while attempting to park and shut off her vehicle. The contact would be forced to repeatedly move the gear shifter back and forth from the park (P) position until the system recognized the gear shifter in the park (P) position.

The morning I started my trip. My back up camera stayed on. I stopped turned the car off and back on. It was still on. Turned it off again. This time the camera went off. I was going up the cajon pass. No warning light or anything. Was coming up to my exit. Tried to slow down to exit. Couldn't press my brakes. They were rock hard to press. Took my foot off gas. Slowed down enough to get to the shoulder of the road. Once I was able to stop. My brakes were hard to press they made a clunk noise. I noticed the check engine light was on. I could of been killed had someone been in front of me and stopped. Or I could of killed someone. This is not the first time these brakes have done this. They did it earlier this year I wasn't able to press my brakes as and when I was it made the same noise. I had it towed to dealer to be fixed. They said they fixed it. This could of killed me or someone else as I was traveling on the freeway at faster speeds than the streets
