NHTSA recall 21V874000 · Nov 10, 2021 · 208,332 vehicles

Dec 1, 2025 · crashService brakes 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 of a concrete wall. The problem has not been confirmed by the dealer as of yet. No warning lamps, message or other signs of malfunction were evident.

Dec 9, 2023Electrical system Owner of 2019 A4 recently purchased from dealership after lease expired in Feb.2023.

Nov 16, 2022 · 1 injuryForward collision avoidance › Automatic emergency braking 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.
