2018 CHEVROLET TRAVERSE Complaints

The contact owns a 2018 Chevrolet Traverse. The contact stated that while parked or stopped at a traffic light, after releasing the brake pedal the vehicle failed to move. The contact had to wait approximately twenty to thirty minutes and restart the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to NHTSA for assistance. The approximate failure mileage was 35,000.

Transmission fails at low speeds (school zones) reengages once stopped. Possible rear end collision due to defect. It’s been happening since the vehicle was new and it’s been repaired numerous times by the dealer to no avail

My 2018 Chevy Traverse started to have a "shift to park" issue at 49,000 miles. I can not turn the car off because the vehicle states that it is not in park. I have to sometimes literally sit in the vehicle for 10-15 minutes waiting for the car to agree that its in park. Very dangerous. Dealer says it is not covered under warranty at I have to pay for it out of pocket.

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.

Even though the car was shifted to "park" there was an "action needed" message saying shift the car to park. The lights and radio stayed on as well as the Warning bells indicating something needed attention. Even after repeatedly restarting the car and aggressively shaking the shift mechanism, I couldn't get the car to turn off. I wasn't able to lock the car doors. I went inside the grocery store and shopped. The car was still "on" when I returned. I was afraid I would run the battery down as everything was still on. I drove home (9-10 miles) and parked in the garage. After switching off the ignition (yellow light still on), I still got the action needed message and the radio, lights were still on. I went inside and returned 20 minutes later and the car was off. This is the fourth time I've had this problem.

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.

Shift to Park message displays on the Driver Information Center (DIC) when the vehicle has been shifted to Park and the ignition has been turned to the Off position. This causes alarm chimes to go off when door is opened and the battery to drain.

Vehicle does not turn off...gives a "Shift To Park" notification even though the vehicle is in park. Play with the shifter and sometimes it will turn off. Restart engine and turn off again sometimes helps but usually has to be done multiple times. If left as is the issue will drain the battery. Cannot leave vehicle in this condition. Late for appointments. Reported issue to dealership on day the 36 mo. warranty was up and they said not in and diagnosed. This is a known issue from multiple Traverse owners yet the car was not in the shop and diagnosed. Issue began 2/27/21 and was reported to dealer 3/1/21 first available open time of dealership service department. The want $207.xx to fix the problem...if the fix helps.

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.
