Owner report 11495253 · 2022-11-29 (November 29, 2022)
Audi Presense kicked in so violently on the 280E freeway towards NYC from Northern NJ, that my 15 y/o son now has a significant cervical spine injury, necessitating medical evaluation and treatment. The brakes were so abruptly applied by Presense that we thought we had been hit by a car, but had not been in an accident. This is very dangerous, and now my son is injured, despite no accident occurring.

Owner report 11702852 · 2025-12-03 (December 3, 2025)
As I was pulling into a parking spot, traveling at a low speed I naturally applied the brakes but the car accelerated instead jumping a concrete curb and hitting a wall. In that moment I realized I had no control of the vehicle. This sudden unintended acceleration was accompanied by a loss of braking. Pressing on the brakes harder did not stop or slow the car. Brake and accelerator failed. The vehicle is available for inspection. Thankfully the car hit a wall, and there was no injury to myself or others. The parking spot is positioned in front …

Owner report 11418824 · 2021-05-27 (May 27, 2021)
I am filing a complaint concerning my recent experience with the Audi service department located in San Rafael, California. On May 24, 2021 I brought my 2019 Audi A4 in for service due to an error message stating, "Front parking aid: malfunction! Obstacles cannot be detected".
