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…

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.

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…
