general problems of the 2020 Chevrolet Malibu - part 2

Vehicle lost power after trying to go around a truck on the highway. Car will decline in power and traction light and engine light blinks for a period of 60 minutes some times longer. While in traffic you can not press the gas to go, leaving your car to decline in speed on the highway. Please recall the 2020 Malibu before someone get seriously hurt. Dealerships are aware. Do I need to get the news people involved? mine has been happing since my purchase. ( new car purchase) service departments dont understand it either. Had my first cylinder and injectors replaced February 2022 , second cylinder and all injectors replaced April 1st. 2022. Horrible car.

Engine loses power while driving. This happened the first time on 8/24/21 I was on the NJ parkway in highspeed traffic . The vehicle would not drive over 25 miles an hour putting all occupants in the car at risk. The dealership repaired the vehicle the same loss of engine power re-occurred on 3/12/22 while driving at over 50 miles an hour. The car just slowed without warning, and I was unable to increase speed on a busy roadway.

This issue started at approximately 19,500 miles. While accelerating to enter a highway or to pass a vehicle going less than 55mph on a two-lane, service esc light appeared on dash. Loss or power was also immediate and if I tried to accelerate to maintain speed, engine was very rough in responding with no acceleration. Engine continued to run. Within 30 seconds or so, acceleration is restored, and check-engine light was flashing. Check-engine light stopped flashing after a minute or so. Initially, this only occurred occasionally during fast acceleration as mentioned above. Lately this has happened during continuous acceleration, such as using cruise control, while climbing a low incline hill (~15?). Over the past year or so, chevy dealer has replaced, pistons, fuel injector, and did a carbon cleaning of engine. No solution yet.

Sometimes when I drive my car it loses power especially when I’m turning into on coming traffic it will lose speed and I’ve almost been hit on numerous occasions. I’ve taking the car to chevy dealership 4 times already the last time they discovered transmission issues they repaired it. They tell me they don’t see anything else wrong. I have read reviews from other owners and they are experiencing the same exact problem.

While driving down a mountain in monterey tenessee from visiting a friend the car started blowing white smoke and all dash lights flickered before car shut off no brakes or steering while coasting down mountain almost got rear ended by pickup this was around 9pm it was dark I coasted into a gas station after a few attempts to start car . I called roadside assistance that night and got towed to dave kirk chevy dealer next town over after having issues with car I encountered issues with manager of dealer ship and roadside assistance neither could help til I started raising my voice I was stranded there in town for 2 days my friends felt bad the paid for my motel since I was so stressed out they didnt want to look at my car that manager said he knew nothing about after diagnosing my car they found a bad fuel injector that he said was open 100 percent so after 2 days I was on my way back to florida bad experience all the way around.

Was traveling at about 58 mph down the highway when all my warning gauges starting going off. My digital dash went blank and the car started accelerating on its own. I kept hitting the brakes trying to make it slow down and I could hear the abs function and feel it thru the brake while trying to slow down. After about a 1/2 mile of fighting the car the dash turned back on the check engine light stayed on and the car stopped trying to accelerate but wouldn’t change gears and was stuck at 3500 rpms when I limped it off the road and had a tow truck come get it.

Why driving on the interstate with some congestion I made an attempt to accelerate from behind a slow moving truck and in doing so my car slows down as if it stalls in the middle of road. Engine light and traction comes on. During this I cannot apply acceleration until my car is ready. Normally I’d have to pull over but if I’m in traffic I can not. This has been reported to the dealership starting at 900 miles. I was told it’s probably bad gas. I continue to report and was advised nothing is wrong. I have noticed a change in applying acceleration. Its more a force to go. This has been going on since the purchase. I am now at 19, 273 miles.

Engine light came on before a full year of having the car. Started August 23 2021 the car will take forever to move like engine was lock up or something then when you put the car in drive it was go backwards and when you put it in reverse it will go forward. Car has a head of its own. I am pregnant I don’t feel safe in this car and this car is not safe for my baby to be in I spoke to different people who has the same car as me they experiencing the same thing 2019 and 2020 . .

Car lost power when passing a truck on the highway, hard start,immediately contacted dealership. They have had the vehicle for going on three weeks tomorrow. They haven't been able to diagnose the problem. I have contacted gm and the service representative at the resolution center said the dealership was not answering e-mails and he could not give us any information. The service manager at the dealership said he and the master tech had both driven the car and both said that they detected a problem. The service manager said the diagnostic computer showed excess, or unburned fuel in the #2 cylinder. The master tech said he put a bore scope into the #2 cylinder and saw a burned or discolored spot on the piston. The service manager said that a regional engineer had come down from spokane wa. And driven the car with another diagnostic computer. They still have not diagnosed the problem, and the dealer says that gm wants us to take the car back and drive it. We feel the car is unsafe and we are refusing to drive it. They are not coming up with a resolution to this safety problem.

My 2020 chev Malibu promised on the web site and on the msrp that it would get "29 miles per gallon in the city". This was also promised on the 2021 model. I have only gotten 24 mph or less in the city. The car is one year old. I have had three meetings & service check outs with the dealership and they tell me that that there is nothing that they can do. So, I need government intervention to fix my vehicle so that it gets what was promised.
