The issue is with the Traverse Stabilitrak system. The Stabilitrak system controls, includes traction control, emergency brakes, tire monitoring, etc. as I understand it. The Stabilitrak lights has been intermittently coming on for several months. I took the truck to the manufacture and was charged over $1,700 to fix the problem. After the repairs, I picked up the vehicle and within three miles of the dealership the issue manifested itself again. The Stabiltrak system light usually indicates as the vehicle waits at a traffic light, and just as I accelerate for the signal change. The vehicle frequently stalls at that point, creating a rear end hazard, and a dangerous situation for me and other commuters. Upon returning the vehicle to the dealership, they claimed not to be able to identify the issue, that they initially charged me over $1,700 to fix. The said they could not recreate the problem, although it is a persistent problem that occurs within minutes of the vehicle operation.

Shift to Park Issue. Other years have been recalled for this issue but not 2018 (specifically this vin#). Car doesn't recognize when parking gear is engaged and asks for parking to be engaged. Issue is happening more often and it's becoming harder to park the car. Dealership says nothing can be done unless out of pocket.

Shift assembly has failed twice - April 2021 and April 2024. For both occurrences, the vehicle spontaneosly stops registering when I shift into park. When I shift, the vehicle sends a warning to shift into park. There is a safety concern because I cannot determine whether or not the vehicle is actually in park. The GM dealer determined that the issue is a faulty shifter switch and harness and a faulty shift knob. Both were replaced. In April 2021 transmission shifter (part #84698649) and jumper harness (part #84733196) were replaced.

Switch is all messed up and alot of people have hte same issue an ddealer/manufactrurere refuse to do anything... they will fix it, at owners cost, for 700 bucks, which it only took me 30 minutes, not 2.5 hrs like they said.

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.

Electric Park Brake Malfuctions frequently. Park brake will not set or release properly which is dangerous and could allow vehicle to roll out of park on a hill. This problem is well documented online from other owners of 2018 Chevy Traverse but Chevy had not formally addressed this problem.

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.

We parked and exited the vehicle (turning it off) on a slight grade as we normally do in the front of our house on a public street. We awoke the next morning to discover that the vehicle had advanced or slid forward approximately 15' coming to rest against a telephone pole adjacent to our corner property. If the telephone pole was not in the path of the vehicle it would have crossed a side street and come to rest in our neighbors front yard. Upon viewing the vehicle after the drift forward, before entering the vehicle we could see that the vehicle was clearly in park and turned off. The vehicle has approximately 40,000 miles on it and has had (1) previous service by a dealer for transmission slippage from 1st to 2nd gear.

When applying the brakes the vehicle feels like gears are grinding and the car is breaking harder than I am applying pressure on the brake pedal, and I can feel the vehicle shuttering and grinding to a stop through the pedal. The vehicle does stop, but a warning then displays on the dash "brake assist activated". this warning displays everytime the brakes are used. Only have disabling the forward collision break assist does the vehicle then drive normal. This issue has occurred twice now once in town driving 30-40 miles an hour and another stopping coming up to a light at intersection.

Reported brakes squeaking in December of 2019. Now both the front and rear brakes squeaking. Took it to the dealership 3 times now. They state it's noise, not a brake wear issue. Our neighbors also have a 2018 arcadia which does the same squeaking as ours both when you first start the vehicle or apply any traction such as going down the driveway, slow breaking or driving and brakes on a low mph speed.
