What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated that while driving at various speeds, the vehicle would independently come to a complete stop as the brake, air bag, and seat belt warning lights would appear on the instrument panel.
At 70,000 miles with only one owner, it develops transmission problems, making it unsafe to drive and control the car; control of the car is lost. Here is the link from the Dealer [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Tire Brand: Continental Tire Line / Model: ProContact TX Tire Size: 225/40R18 What Happened: This is the second tire failure I’ve experienced on Continental ProContact TX tires (OEM on my 2020 Audi A3 S Line). At only 13,000 total miles, I’ve had two separate instances of sidewall bubbles on different tires.
Car has 50,000 miles and vehicle has a bulletin on the vehicle from Audi, where the vehicle goes into limp mode and only shift through certain gears, rendering the vehicle, unable to drive and creating a safety hazard due to the fact that it can’t drive at Highway speed and or jolt and skips gears.
The contact stated that while operating the vehicle, the transmission malfunction warning light was displayed, and the vehicle failed to shift into reverse. The vehicle was driven to the local dealer who diagnosed that the transmission mechatronics had failed and needed to be replaced.
The seatbelt sensor also goes off when no one is in the seat. Audi dealership said this is an Audi issue and the parts are not in stock. This is a huge safety issue.
Our vehicle was purchased new a year and four months before the tires were considered completely "dry rotted" out by the Audi technician. The vehicle has 35, 737 miles on it, but it was all highway commuting driving.
The dealer informed the contact to latch the front passenger’s seat belt latch at all times. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was approximately 7,000. Parts distribution disconnect.
