2023 Audi Q4 E-TRON Sportback

While driving, the car lost power, stalled, and rolled backwards down an incline. Fortunately, the brakes worked allowing me to bring the car to a safe stop. The dealer has been trying to repair the car for 40 days (the repair is not complete). The repair included replacing the front motor. When I went online to the Audi forums, it appears many drivers have experienced the same problem. Some type of refrigerant leak causes a failure of the front electric motor which causes the car to lose drive power (stall). I can't tell from the online forums how prevalent (or rare) this problem is, but it is clear that I am not the only Audi Q4 owner who has experienced the same sequence of events.

On September 22, 2023, I was parking the car in a parking garage and I had my foot on the brake. I was about to shift to reverse when my car suddenly accelerated on its own into a cement wall. My foot had remained on the brake the entire time.

As I was starting to make a right hand turn into a parking space in a parking garage, the car suddenly accelerated. I slammed on the brakes, but the stopping distance was not long enough. The car crashed into the steel cabling and concrete pole. The airbags deployed and the damage was significant enough to total the car. I sustained bruising and back muscle pain from the force of the impact. I only had the car for 11 days when this happened. I requested black box data for the car from the collision center and insurance company - neither would provide. I also reported the incident to my Audi dealer. Had there been a car in the parking spot next to me or directly in front of me, there would have been significant damage to other vehicles.

On April 14, 2023. I was driving west bound on Warner Road in Tempe. I bypassed the shopping enter and turned into the church parking lot - to drive through so that I could change the direction to go East on Warner Road. While driving through the parking lot - only doing about 10 miles per hour, the vehicle sensors "Adaptive Driving" feature - motioned the vehicle which case the right front to hit the base of the concrete lamp post. The parking lot surface consist of hairline cracks - which the sensors obviously picked up and caused the impact to the concrete base.
