My vehicle randomly throws on the parking brake while driving. I have almost been rearended because of it. In order to get the parking brake to release i have to shut off the vehicle and wait 30 seconds then when I restart it, it releases. I get a message on my dashboard when this happens that says Auto Emergency Braking (AEB) limited functionality service required. This has happened multiple times and the dealership has no clue how to fix the issue. This is a safety hazard to not only me, my unborn baby and my family, but also to others on the road because there is no warning before it sets the parking brake. I will list the most recent time this has occurred.
