This Traverse is the Redline Edition. Beginning in November 2022, the Right Passenger quarter LED tail Lamp stopped working. it operates the turn signal and stop light. It is unavailable since that time. It is now 6 months I have been operating this vehicle which is unsafe. It is the whole assembly and I cannot replace it with the regular taillamp due to the wiring harness. I was told from Chevrolet to go to the dealer and the dealer tells me that the part has been on National Backorder for months.

I placed my car in park & an alert went off stating, -??shift to park.-?? My car would not turn off, after multiple attempts, until I turned it on & off & drove the car a short distance. This has happened several times this month, with no warning or symptoms. My car is currently in for service & the dealership mentioned there-??s a shortage in the switch, requiring a $400 repair. I feel my safety & that of others, is at risk, as my car currently does not know if it-??s in park or drive. What-??s to say this issue won-??t arise, when I-??m driving down the interstate at 70mph" Or I am having a medical emergency & can-??t turn my car off to place it in park" I did a google search & apparently this is a very common issue with this type of car. The dealer mentioned it would have been covered under a 3 year/36,000 mile bumper to bumper warranty, but my car is 4 years old with 37,000 miles on it.

Shift to park error. Happens often when the car is in park, the error states that the car is not in park and has an alarm that goes off. I am unsure if the car is safely in park and not sure my car will lock if I do not try to cancel out the message by continuously starting the car back up and shifting the gears to ensure it is in park. It happens very frequently. I was told by the dealership that they have replaced a lot of these parts and they are not sure why a recall has not been issued yet.

Rear taillight has moisture inside which can cause an electrical shortage. Upon Google search, there are tons of other 2018 Traverses with the same issue. I contacted the dealership about a GM service bulletin about the same issue but they stated we would have to pay out of pocket for this issue.

- Jacksonville, NC, USA

The driver information display indicates the vehicle is not in park when it is shifted in park and engine is turned off. A warning chime goes off and will not stop until the button on the shifter is flipped multiple times. I talked to the service manager and he indicated that many vehicles are showing this fault. The entire shifter assembly would have to be replaced to fix the issue. There is a microswitch on the assembly that is the cause of the problem. My concern is this false indicator could lead to a safety issue for drivers who don't understand the issue. Also why isn't a recall issued by GM since many vehicles have displayed this problem. My other concern is the daytime driving light is intermittent on this vehicle but what else is next to fail electrically.

- Stow, OH, USA

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.
