This is ongoing. Originally got trouble code p0239 after check engine light, cleaned throttle body. It went away. Then i got the same symptoms as a result of the throttle position sensor. I replaced that as well. Then i got a code for the turbo boost sensor. So i replaced that. Now I'm getting similar symptoms and the check engine light isn't turning on at all. I suspect maybe a catalytic converter, ecm issue, or transmission issue. I've repaired all problems that have given me a code. The car accelerates very slowly, while the rpms go up normally, then the car bolts off almost normally for a while. And becomes jerky. So I'm unable to safely pass others if needed or accelerate normally both from a stop and while moving. While driving at low speeds with the window down I can hear a sound that could be the turbo spooling up or maybe a fan. Also, the cooling fan will stay on for a while after turning off the engine. I contacted the dealer and they said the only recall is a CAC retainer and told me there were no other TSBs open for my VIN but i believe by car is eligible for multiple including but not limited to 19-NA-058.

GM 2019 Chevrolet Malibu - Report Shift to Park Issue - Mileage 13,784. I would like to report a Shift-to-Park problem I had with my 2019 Chevrolet Malibu. Approximately two weeks prior to this service call I started experiencing a problem with Engine Start/Stop button and “shift to park” message on instrument panel. Pressing Start/Stop button would not turn off engine. It took several attempts to completely turn off engine. Two weeks and issue was getting progressively worse. Finally on Wednesday, March 29th and having started driving errands, I could not turn off engine at all. I could not get out of the car without warning beeps going off. I immediately drove to Dealer Service as I felt unsafe to drive. Dealer Service performed and I picked up car on Thursday, March 30, 2023. They replaced shifter switch and installed jumper harness. Again, I do want to report issue as this car has only 13,784 miles. Thank you,

Before my car gave out I was having braking issues and my car wouldn’t accelerate when I pressed the gas. Then later that night I was driving home with my mother and fiancée when my car illuminated “engine power reduced” and my check engine light came on. When I tried pulling over I noticed that my brakes were very hard. So I had to roll from the speed of 45 mph until my car eventually stopped. I was not able to stop at the stop sign so I just had to blow my horn to alert other drivers. Whenever I took it to the dealership they told me my brake vacuum pump exploded and blew shards into my camshaft. The repair was 1700 for the replacement of the brake vacuum pump and the camshaft. I talked to the mechanic afterwards and he said that this problem has a good chance of happening again because the part itself is defective and there are no other aftermarket parts to replace it. Then I go to pick up my car three weeks later, and was told that my engine should be replaced because a cylinder had no compression. The price of that was around 5000.

Numerous times while driving my car both my son and I have experienced the same issues. Trying to get on the highway and pressing the gas pedal the car isn’t responding appropriately to the level of which the gas is being pressed. It isn’t accelerating appropriately. Than at stoplights or just trying to make a left hand turn from a stop position. You take your foot off brake and press the gas to go and it rolls a bit and you’re pressing the gas to go and the car isn’t responding. It’s just sitting there. Like paused. Then all of a sudden the car engages and takes off. It is very dangerous to not have the car respond to pressing the gas. And I don’t want to get into an accident because I’m trying to make a turn and get hit cause I’m just sitting there. Rather than it going when I’m pressing the gas. I am not getting any codes popping up on the dash. So the dealership has nothing to look at other than me saying this is happening to me and my son. I’m finding issues similar to this on previous models. But nothing on the 2019 that I can find. And with no error codes registering. But the issues occurring is highly concerning to me. There isn’t just one date this has occurred. This has happened now many times over the last 6mos.
