2022 Audi e-tron Brakes Problems

Brakes were replaced by Audi with genuine Audi parts and within 2 months, the brake rotors became warped, requiring a resurfacing. After driving another 2 months, they once again became warped, making the entire car lurch and shake during braking.

Brakes do not work when there is a precipitation. You need to press the brake 3 times before you can feel the brakes engage. This occurs anytime it rains or snows for the entire time we’ve owned the car and Audi refuses to acknowledge the complaint

My drive motors keep failing (so far 3 times) and my emergency braking abruptly stops my vehicle when no true danger is present and I’m in complete control of my vehicle. Currently my vehicle has a constant shuddering while braking which doesn’t feel safe because it’s not braking properly. Audi regional and the dealership refuses to take ownership of the issue. Dealer has confirmed issue and replaced drive motors three times. Each time my braking system has gotten worse. The part was replaced each time under warranty but Audi has not confirmed that a fix has been found and corrected. This means it can occur again and abruptly which can absolutely be a safety hazard as it was each time it failed on me.

On 3 separate occasions brake pedal went all the way to the floor without stopping the vehicle. Pumping the brake pedal did not help as brake pedal went to the floor each time. After a few panic pumps all of sudden brakes worked as if nothing had happen. This was not a gradual regain of pedal force but full force as if nothing had happen. Did not see any indications on dashboard at the time and none were present after any of the events listed below. Note - Each event was after car sat in parking lot for at least 4 hours. First time was Jan 23, 2023 at ~ 12,300 miles leaving parking in the morning onto main road. Fortunately no traffic. Second event Feb 8 ~12,900 miles leaving parking lot onto main road in the morning. Fortunately no traffic. Third event Feb 9 ~ 12,940 miles leaving business parking lot in the afternoon and was approaching the exiting gate which rose out of the way in time for car not to hit the barrier. Car was taken to Audi Service on Feb 13, 2023 to be evaluated. Audi Service could not duplicate issue and kept the car for 11 days. Audi technical team advised replacing the brake booster module (PN 4KE-614-100-AG-BEF) which was done by Audi Service in South Burlington, VT. Original Brake Booster removed from car was kept at Audi Service.

1. The brakes all of a sudden failed. We were at an elementary school in carpool line - near children- the brake pedal did not work at all, nothing. Warning message to stop driving brake failure. The Audi-Sense alert did at least put on the emergency parking brake before hitting a car ahead of us. Turned off and on, checking if computer vs actual brake issue (see below, computer issues as well). The car lurched forward, then warning, got out of line onto side of parking lot. After turning off and on again, it worked to drive again. Unclear right now if brakes actually gone but European recall Sept 2021 suggests this is really a brake issue and recall exactly as described here (I bought this car three months later, which suggests gross negligence on part of Audi here). 2. Tire sensors do not work, wrong readings on pressure. Safety issue. Similar e-tron recalled, but not mine - again, Audi negligence not properly recalling all impacted vehicles. 3. Additional computer errors. The screen goes black when in use and cannot be accessed while driving. Not a safety issue, but controls and visibility are lost. As I can only list 3 problems here will open a second issue for remaining failures on this 9 month old vehicle. Thank you, this model should not be sold in US. Unsafe.
