There was not warning lamps, messages or other symptoms of the problem prior to the failure.

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. Relying on this directive, I operated the vehicle, resulting in a sudden engine seizure inside a high-traffic 4-way light intersection placing my safety in immediate jeopardy.

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 regulations, and has left my automatic emergency crash reporting and vehicle communication systems completely disabled.

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 determined that the communication module failure was the same as the SOS module failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 54,000.
