NHTSA Complaint #11469251 — 2021 GMC ACADIA

My emergency parking brake keeps engaging on its own, as I come to a stop, jeeking me forward. I never even put it in park, but it just engages the parking brake in a forceful manner. At a couple different times, while going at about 40 mph, the car starting shaking terribly, slowing the vehicle. The check engine light came on as well as both parking brake lights on the dash (the indicator light saying the parking brake was on and the indicator light saying there was a problem with the brakes). It felt light the vehicle had engaged the parking brake with I was driving and was dragging the parking brake. I have been having problems with the brakes with the vehicle and have taken it to the dealership a few times for this issue. They only kept it overnight and told me there was nothing they could do because it didn't happen while they had it. I have a fractured back and am disabled, and this issues actually hurts me when it does it.
