“On five separate occasions across two separate drivers, we have experienced a partial brake failure in this vehicle. We strongly believe this to be a software defect and not a mechanical fault. On the e-Tron, the first portion of the brake pedal swing typically activates the regenerative braking. About mid-way through pressing the pedal, it changes to real mechanical brakes. …”
NHTSA complaint #11639800, filed 2025-01“Car turns on but won’t move. Take it to dealership as it happens for the second time and turns out the brakes are sticking to the rotors. Audi says it’s perfectly normal just put force to the accelerator. When you do that in fact, it sound like the car is about to split in half. Dangerous as they could stick while driving anywhere. Scared for my life in the car.”
NHTSA complaint #11488720, filed 2022-10“Moisture build-up in the high-voltage electrical system through a faulty seal on the charging socket, which can cause a short circuit and significantly increase the risk of a vehicle fire. If you get a warning light saying electrical system: fault, you should stop driving immediately, park outdoors away from structures, and not charge the vehicle. Braking problems caused by sub-standard welding within the ABS rotor and shaft. High-voltage battery modules that may overheat, also increasing the risk of fire. …”
