2020 AUDI A3 — Problems, Recalls & Safety Data

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. •The first occurred in 2022 at just under 7,000 miles and caused the vehicle to fail PA state inspection. Continental covered 50% of the replacement cost after I submitted a warranty claim. •The second bubble appeared in June 2025 on the front passenger tire. At that point, I replaced all four tires out of safety concerns and disposed of the Continentals. The vehicle is in excellent condition, lightly driven, and is not exposed to potholes, curbs, or harsh use. I work remotely, so mileage is extremely low. Both tire failures were from normal road use and developed without any impact or external damage. I contacted Continental again in June 2025 with a full explanation and referenced my prior case. They refused to offer any goodwill or further investigation, stating that I had already disposed of the tires. ⸻ Why This Matters: Experiencing two identical sidewall failures within 13,000 miles on different tires under light driving conditions suggests a potential design or manufacturing defect. I’m reporting this in the interest of safety and awareness, as a sidewall failure at highway speed could be far more dangerous.

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. Code for the P173600 known issue by Audi, went into mode while merging onto freeway and a lost control of vehicle.

The contact owns a 2020 Audi A3. 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 vehicle was not yet repaired. The manufacturer was not contacted regarding the failure. The failure mileage was 17,525.

As of October 25, 2022, the manufacturer (Audi) continues to not provide a solution to Recall Number 69BY / NHTSA Recall Number 21V198, stating that parts are still not available.

The passenger occupant detection system has permanently failed and causes my passenger airbag to be off at all times including when a passenger is seated in the vehicle. 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.
