The vehicles dashboard lit up with a service emergency brake, and then the brakes locked up while the car was in motion on the roadway.

When I turn off the vehicle, there is an audible dinging that does not stop and a message "shift to park" on the screen. This warning and message does not stop and therefore would run down the battery if left. I googled a solution before taking to the dealership and it turns out, this is a common failing in many Chevy vehicles. It is a small part located in the shift control, literally a 1 inch strip of flexible metal, that isn't making a good connection to a sensor. Chevy should fix this or replace for free since it is clearly a defect, but instead service departments charge a diagnostic fee ($169) and I was told it would be a $777 fix on top of the fee. With the "shop fees" it would cost $1,000.

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.

When the vehicle is in park the -??shift to park-?? error comes up on the dash board and the car can not be turned off. This appears to be a common issue and a recall needs to happen.

- 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.

- Grayslake , IL, USA

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.

My vehicle will not always go in to park allowing the vehicle to move and not to be locked if it doesn-??t roll when -??parked-??. GM knows this is an issue and refuses to do anything to correct the issue.

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.

Auto will not shut off when put in park. Message indicates 'put in park'. tried several times. Engine will go off, electronics stay on. Would drain battery if left on. Also, bluetooth continues to disconnect. Brakes squeak constantly, from the time it was driven off the lot. Car stutters when you attempt to accelerate. Car has been to dealer many times, supposedly 'fixed'. I was told to try higher octane gas. This should not be necessary. Electrical problems are increasing. We have purchased several Chevrolet, this is the absolute worst vehicle as far as problems which, after 2-1/2 years, have not been repaired. Why is there not a recall"?" car is currently at the dealer, again.

I had purchase a 2018 Chevy Traverse from curry Chevrolet in the same year, I notice a little slipping with a little jerking sometimes a few months later and the shift to park was acting up. I called curry and asked them is there any problems or recalls with this model, service dept said no, then I had called a deferent dealership they said the same, and I had call curry about three times regarding my this problem, so I kept checking my VIN# on Chevy.com nothing comes up. So I went on line to find out I wasn't alone regarding these problems even with later models. Then I called customer care twice to make sure the info I was giving was the same, I had explained my problems with them, she said there are no recalls under my VIN# at this time, I went over my warranty with both customer reps, both were accurate that my vehicle is still covered. I also received info there is a bulletin out #18-na-121. I am hoping there wont be any problems correcting these issues, I am prepared for a fight getting a lawyer and going to many news stations, I don't understand why would you put a defective part not only in my model but others with out solving the problems first according to other owners that had posted the same problems with the powertrain. I am truly disappointed with Chevrolet, and to think I left Ford & Dodge.

Power steering failed on vehicle while in motion. Electric power steering module failed causing extreme difficulty getting the vehicle parked. Steering rack had to be replaced and computer re-programmed. Vehicle is back at the dealer with a similar trouble code for a follow up to the original repair. It took GM over 4 months to get the replacement part making us drive our vehicle with a faulty steering rack never once providing a loaner vehicle or buyback opportunity.

When you put the car in park and go to shift it off the car doesn't senses that it's parked. Will not shut off completely and can't lock or arm car. Restarted car several times and still signals the car is not in park.

- Hyattsville, MD, USA

Shift to park error message while the vehicle is in park. This prevents turning the vechicle off, locking the doors, etc. This problem has been well documented on several thousand vehicles. However, GM has only quietly fixed problem case by case and will not cover under power train warranty. A national recall should be issued asap to fix and replace the shifter. Poses a safety issue as well since it involves a faulty gear shifter.
