NHTSA complaint #11758372

Owner complaint summary

We live in [XXX]. We own a 2021 BMW X5-45e. It has about 85,000 miles and has always been serviced by the BMW dealer here in [XXX] – Pierce BMW. On the evening of XXX I drove the vehicle home at 6:30PM after a 30 mile drive and parked the car outside in the shade of our house. The temperature at the time was approx. 95 degrees F. At 6:45PM we left the house and drove on the freeway and city streets of [XXX] about 8-10 miles to see a concert in downtown [XXX]. The temperature at that time was about 90-92 F. There was no wind. We then parked outside the venue for about an hour and watched the concert. We came out of the concert at about 8:30 and started the car. I drove about 200 feet to the corner and stepped on the brake. As the car slowly came to a stop the emergency/parking brake suddenly engaged at about 2-3 miles per hour. The car jerked to a very sudden and violent stop. To get the car going, I had to disengage the parking brake which was on with the indicated brake light. The engine was still on and there were no warning lights flashing. I turned the corner and accelerated again to about 15 miles per hour and touched the brakes to bring the car to a stop. The same thing happened. The car jerked to a sudden stop. To get the car going, I had to disengage the parking brake. The engine was still on and there were no warning lights flashing. It also happened a third time. That time, my elderly wife complained of pain in her back. After the third time, I turned the engine off and waited about one minute. I then restarted the car and drove it home with no problems. We have had no further issues, but this is a big concern as we no longer trust the car to perform as expected. This is a very worrisome issue and would like some answers, but apparently none are forthcoming. I took the car to Pierce BMW and they could find no fault code or problem.
