2017 AUDI A4
Filed Oct 16, 2026
I am reporting a recurring safety defect involving the interior speaker trim assemblies on my 2017 Audi A4 Prestige. The affected speaker trim was previously repaired under an Audi safety recall by an authorized Audi service provider. This recall repair is documented in Audi’s service records. Despite the completed recall remedy, the same component has failed again. The deterioration affects multiple locations in the vehicle, and sharp edges are now exposed, creating a potential laceration…

I am reporting a serious vehicle safety incident involving my 2018 Audi A4. On XXX, while traveling from [XXX] to [XXX] with my [XXX] son in the vehicle, all four tire valve stems failed during a single interstate journey. The first failure occurred on the front-left tire, causing nearly instantaneous tire deflation. After an emergency repair, I continued driving, but the remaining three valve stems subsequently failed in succession. Each failure created a potentially dangerous situation…

Date: [XXX] Time: Approximately [XXX] Location: Street in front of [XXX]. At approximately [XXX], my wife was seated and properly belted in the front passenger seat of our 2020 Audi A4.

I was going from one section of the parking lot to another section. I was slowly making a right turn into that area as there were a lot of empty parking spaces. As I turned, suddenly I felt that I could not control the car. I tried to steer and tried to stop the car. I was alarmed, thinking why the car won’t stop. Then my car slammed into a parked car, and spun it around. My car finally came to a complete stop. I don't know if the same problem has been reproduced. The vehicle is now at…

2014 AUDI A4
Filed Aug 28, 2026
I am reporting severe vehicle safety defects and merchant safety non-compliance regarding a 2014 Audi A4. The vehicle was financed with severe, undisclosed engine defects, specifically extreme oil consumption and catastrophic coolant leaks. When I requested warranty repairs, a dealership representative named Stephen explicitly instructed me in writing via text message to intentionally operate the vehicle with active oil and coolant failures until the engine suffered a total mechanical blowout.…
2020 AUDI A4
Filed Aug 12, 2026
My 2020 Audi A4 has an open safety recall campaign. Audi Corporate and my local dealership are formally refusing to perform the recall remedy unless I pay over $2,000 out-of-pocket to replace a broken J949 SOS Telematics Module. The manufacturer claims the module is separate from the recall, but its total failure physically blocks their diagnostic tools from applying the mandatory safety update. Conditioning a federal safety recall on a customer-paid repair violates recall compliance…

The contact owns a 2020 Audi A4. The contact stated that while driving at an undisclosed speed, the message SOS module no longer connected was displayed on the instrument panel, and the vehicle failed to shut off. The contact believed that the failure was a safety issue due to the loss of communication, including the hands-free features, mobile phone connectivity, and the regular safety features failing to operate as needed. The vehicle was taken to a dealer to be diagnosed, and it was…

Oil consumption is extremely high this vehicle burns way to much oil in short amount of time. Oil has to be added every 300 to 400 miles and there are no leaks present
