NHTSA Complaint #11446809 — 2018 CHEVROLET TRAVERSE

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.
