Purchased 2018 Chevy Malibu with 4,200 but new due to it being a dealer courtesy car on 12/18/18, on 1/7/19 the car would not accelerate while stationary in a parking lot attempting to pull out of the parking spot. I put the car in park and when shifting back to drive the transmission slammed into gear and the accelerator barely responded and the car revved to over 5,000 RPM's. I took into superior Chevrolet on 1/8/19, on 1/11/19 they still did not know what the issue was and were unable to duplicate it. On 1/4/19 the dealership said they were connecting the car to a machine that would supply the smallest specs of the car to send to GM engineers, on 1/16/19 the GM engineers advised to replace the tcm (transmission control module). Tcm was replaced and the car was picked up on 1/18/19. On 5/22/19 while driving through an intersection the accelerator failed to respond again and revved to 5,500 RPM's. it took approx one minute for the accelerator to respond in the meantime I was almost rear-ended by the car behind me. I took the car back to superior Chevrolet on 5/23/19 reporting the accelerator did not respond again as it had in January. The techs were unable to duplicate the issue again and the service manager drove the car home to see if it would duplicate, it did not. On 5/24/19 I was advised they updated the computer and that should resolve the problem this time. The first failure happened at approx 4,700 miles. The second occurring at approx 11,700. The consumer stated upon the 3rd failure the onstar diagnostic stated that there was an issue with the engine and transmission system.

The vehicle loses power after warming up. Vehicle sputters during acceleration and sometimes will not accelerate at all. This almost caused me to get into an accident as I pulled out and pressed the accelerator and the car would not move. There are no lights or codes present. According to online forums there is a tsb for this (19-na-32); it needs to be a safety recall...this is very dangerous.

At any given time, when vehicle is stationary and shift lever set to 'park', the instrument panel screen displays a 'shift to park' message even with the lever set to the 'park' position. The vehicle seems to be in 'park' however, battery power to the vehicle remains and will not shut off. Car electrical system remains on and honks three times if the key fob is not in range. It is concerning that the vehicle is never fully in 'park' mode or that the vehicle is never fully turned off and can cause an accident if unattended.

Bought this car brand new in August 2018. When I drive it sometimes it looses power when I'm driving from a stop or while picking up speed and it doesn't matter if it's on the freeway or on the street. The only way I can describe it is it's like the transmission gets stuck in a high gear and slowly builds speed up. It is very dangerous to drive it like this.

I bought this car brand new 9/28/2018 with 2 miles on it. Every once in a while the car will stick at 3400 RPM's, making almost no power, while trying to accelerate. The car will do this from a stop or trying to pass a car. Brought to dealer for 4 days, they couldn't duplicate the issue as it doesn't happen all the time(eye roll) it is a major safety concern as it will give you a false sense of security when moving into or around traffic and is very dangerous. Monitoring the car thru the obdii port I personally found it not building boost from the turbo when it's having this problem, unfortunately the dealers can't see this problem...
