Attempted to park vehicle in level parking lot. Vehicle appeared to go into Park. Driver Information Center indicated that vehicle was not in Park and provided warning bells. When exiting the vehicle was providing warning more warning sounds and would not stop. Vehicle was in Park, but would have run warnings until battery discharge. Tried cycling vehicle, contacted On-Star and began troubleshooting with them. I was unable to resolve with them and GM support. Took to dealership and after troubleshooting was resolved by following steps in TSB 19-NA-206 which was performed outside of any warranty coverage.

On January 9, 2022 I was unable to release the parking brake. When I turned the car on, an alert popped up saying -��service parking brake-��. When I tried to release the parking brake, it would not release. It still made the sound as if it was trying to release but the parking brake was still engaged. I turned the car off and went back into my house for 10 minutes and then came out to try it again. Again, when I turned on the car, it said -��service parking brake-��. I tried to disengage the parking brake and it wouldn-��t release. I pulled the button up as if I was setting the parking brake and pushed it down to release 3 times, with no change. On the 4th try, the parking brake disengaged. I received an email from OnStar Notifications informing me of the issue and directing me to take it to a service center. (Pic of email attached) This component has not been inspected by anyone. I would be willing to make the vehicle available for inspection upon request. This issue compromises safety because I have to set my parking brake, as I park on an incline and my truck rolls back a little each time I put it in park, or release the parking brake. It would be dangerous to leave my truck parked without the parking brake, but I can-��t have my truck stuck with the parking brake on when I need to leave.

Electrical ground problem affecting transmission control is evident by a Shift to Park warning that displays on the driver information center and prevents vehicle from being turned off. GM has this problem so we-��ll documented that a TSB exists and is on file with NHTSA. The inability to turn off the vehicle when this is encountered is a significant safety issue. We paid out of pocket to have the fix recommended in the TSB applied to our vehicle.

When driving on a right hand curve with traffic in the opposite direction lane, the forward collision warning system flashed a large red warning flash on the instrument panel near the speedometer. This was alarming and caused me to put on the brakes immediately, although there was no impending crash. This cause the cars behind me to take evasive action and apply their brakes in an emergency fashion and almost cause several collisions.

- Magnolia, TX, USA

The car does not recognize when the vehicle is in park. It will ding an error at you so you are unable to leave your vehicle. This error will continue to go off until you can find a trick to shut the car down. I work downtown and need to park in a garage. I was left sitting with an alarm going off for several days while I searched for tricks on my phone to get the error to turn off. I am a single female and I was put at risk because my car would not turn off. I had to sit in the garage alone until I could find a way to be able to leave my car.

When my vehicle has been shifted into park (the transmission shifter shifted into P for Park) and the engine has been turned off a "shift into Park" warning message is displayed on the dashboard and a warning chime sounds. My vehicle's ignition remains ON and the audio system does not shut off. The transmission shifter shows the P (Park selection) P as red indicating the transmission is in park and the transmission shifter is locked in the park position. I must restart my vehicle and re-shift the transmission selector back into park multiple times before my vehicle turns the vehicle's ignition to OFF.

When shifting into park and attempting to turn off the car, 80% of the time the vehicle would not register that the car was in park and allow the vehicle to turn off. It would alarm & charm with a message to "shift to park". this is a known manufacturing issues with the Chevrolet Traverse, GMC acadias, and possibly other models of Chevy/GMC. This is a major safety concern as there is no way to know if the vehicle is truly in park and can leave you in scary situations when you cannot turn off the car. We have also been stranded with a dead battery because the "shift to park" chime and message drained the battery. Chevrolet has provided their dealerships with bulletins in how to add a jumper harness and add/replace a switch in the gear shift assembly to correct the issue, but refuse to take accountability. I have had multiple service advisors admit they have had to fix numerous gear shifters and that this is a known issue. A recall needs to be issued on this problem as it is a safety concern for anyone affected. Please address! I am including my receipt on the service I had to pay for to fix this problem. Also an example of one of the technical bulletins Chevrolet has sent their service department.

Shortly after purchase, my car would not acknowledge being put in park. I would shift the control to park but would get warnings park was not engaged. I took it in for repair. Now I am getting a message to service parking brake. This seems to be a problem with this vehicle. I do not use the parking brake, so I can't understand why service is needed. Both problems were when car was in park. The 'service parking brake' warning stays on while driving.

Bought 2018 new. Two days after driving off lot passenger seat melted electrical connection causing seat failure. GM fixed four days later driver seat same thing. Week later headlight connection melted and had to be fixed spent a week in shop. Started claim at GM to take car back after a month of run around and stalling they offered me $250 in accessories and dropped the problem as it is all fixed under warranty. The diagnostic block under the dash melted so they couldn't use it and had to be replaced. Most recent the left brake light failed and it was because the connection melted and the light had to be replaced. A week after that I was driving on I75 and heard an explosion and the right brake light was blown out of the car. I took it to the dealer and he connection was melted and the car has been in the shop since 29 Sept 20 and today is 7 oct20 the car has only 21700 miles on it. I have again called GM and started again that this electrical problem is dangerous as those lights are led low voltage so what is causing this surge of high voltage and no answer. All repair records are at the dealer and this is not normal to have 6 electrical issues in two years but GM has decided to look the other way. It's been a week since calling GM and I have not gotten this resolved as yet.
