| May 2022 | POWER TRAIN | my 2018 malibu premier with 12600 miles on it, parking sensor, and wiring harness is defective. The shop tells me gm knows about it and recommends replacing them. when you park the car and turn it off it does not go into park, you can not lock the car, and the radio keeps playing. If you do not shake the shifter it stays that way. If you do not have the radio on and you get out and close the door and walk away you do not know it. They want $450 to fix it as long as all goes well.I feel there should be a recall on this since they put in faulty parts and have notified their dealers. | Crash: No Fire: No | Unknown |
| May 2022 | ELECTRICAL SYSTEM,ENGINE | The contact owns a 2018 Chevrolet Malibu. The contact stated while driving 20 MPH and coming to a complete stop, the brake pedal was depressed and the vehicle Stop feature engaged independently as designed, causing the engine to stop running. However, upon releasing the brake pedal, the vehicle stalled and shut off. The contact was unable to veer to the side of the road. The contact shifted into the park, depressed the pedal, and was able to restart the vehicle. The contact stated that the failure reoccurred twice. The vehicle was taken to the local dealer where it was diagnosed that no issues were found. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the dealer. A case was opened. The failure mileage was approximately 58,000. | Crash: No Fire: No | 58,000 |
| May 2022 | POWER TRAIN,ELECTRICAL SYSTEM | I got the error message, "Shift to Park" after putting my car in park. Thus, my car would not fully turn off, affecting the battery. This is a known issue with various make, models, and years of Chevrolet vehicles. If this had happened anywhere but home, if would have left me stranded. The dealership confirmed it was a known issue as they have had to fix many of these vehicles. The bill was extremely pricey. | Crash: No Fire: No | Unknown |
| May 2022 | POWER TRAIN,ELECTRICAL SYSTEM | Component/System: Transmission shift control not correctly sensing vehicle has been placed in parked condition. Symptom: After parking and shutting off engine, message is displayed "Shift to Park" and car dings and lights and electronics will not turn off. Started about a week ago and was intermittent. Jiggling the transmission shift handle would always cause message to go away and electronics to turn off. Today, no amount of manipulating the transmission control handle will shut off the message. Tried to leave car in garage but lights and radio kept running. Decided to manually shut off lights and radio/info system hoping system will time out and shut down on its own. Finally got in contact with dealership who recommended I disconnect the battery cable until I can get the car into the shop. Safety concern: Though transmission can be verified as being in park, electronics will not shut down, thereby potentially allowing the electrical system to drain battery and not allowing car to be started when needed. Also, a bit concerned it was suggested by dealership I disconnect battery cable to eliminate power drain while "Shift to Park" error is occurring. Problem reproduced/confirmed by dealer: Not yet as the problem had a rapid onset from intermittent to full time over the course of a week. Having a bit of difficulty getting appointment scheduled that will get problem investigated and fixed. Loaner cars were discontinued last December and I live too far from dealership to be driven home. Inspection: No inspection has yet occurred; however, I have taken picture of "Shift to Park" message while transmission control handle is in the park position. Prior indications: There were no other signs of a problem. "Shift to Park" simply started and was intermittent over the course of a week. Jiggling the transmission control handle would quickly resolve the issue, then today, it has no impact. | Crash: No Fire: No | Unknown |

| Mar 2022 | POWER TRAIN,ELECTRICAL SYSTEM | The harness and shifter solenoid went bad in my car. When I was on the highway, it stalled causing me to have to pull over onside the road. I nearly got hit in the rear by an 18-wheeler. There was an TSB on the make, model, and year of the car, but GM did not inform their customers of the issue and the dangerous situation one could be in if the car decided to malfunction in the middle of traffic. I was almost rear-ended from behind by an 18-wheeler while on the highway going 60 miles per hour. I also was stranded on the side of the road because they said they could not send anyone out. Malcolm Cunningham Chevrolet, a local Chevy dealer is aware of the issues with the vehicles, but when I bought my vehicle into the shop to get fixed, they lied and said I had wasted something in my car. They provided no pictures of the spills or pictures of the parts with the contamination that they claimed it had on it. The only person that inspected my car was Logan and the other technicians at Malcolm Cunningham Chevrolet in Augusta, Georgia. No, there was no warning lights indicating my harness and solenoid needed to be checked. | Crash: No Fire: No | Unknown |
