Additionally when it’s off it will auto break when I’m not close enough to hitting and it’s loud and yanked me. This has been an issue for some time and I’m seeing a significant amount of my models have this issue and it’s not safe.
SERVICE BRAKES — 11/20/2021
While driving the emergency parking brake engaged itself without warning or cause. This caused the vehicle to come to an abrupt stop. Luckily I was in a parking lot but if I had been in a high traffic area or intersection, it could’ve caused a collision. I had 2 passengers who witnessed this sudden bizarre event. There was nothing that could’ve caused this to happen. It scares me & now I’m worried this could happen again without warning. The sensor screen was beeping with a message to put
