Audi A4 Quattro

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 scan also showed U112100, described as “Data bus message missing,” with status listed as active/static. This is being reported as a safety concern because body-control module, gateway, and data-bus communication faults can affect vehicle electrical…

A vehicle diagnostic scan dated 04/15/2026 at approximately 88,502 miles showed a stored transmission electronics fault: P084100, described as “Transmission fluid pressure sensor/switch A range/performance,” with status listed as passive/sporadic. This indicates a transmission / powertrain control concern involving the transmission fluid pressure sensor, transmission electronics, wiring, control logic, pressure monitoring, or related powertrain components. The vehicle also has prior…

An Audi dealer installed 245/40R18 93H tires on this 2018 Audi A4, while the vehicle placard/specification requires 245/40R18 97H. The lower load index reduces capacity from 1,609 lb per tire to 1,433 lb per tire, approximately 704 lb total across four tires. This creates a safety risk because load-rated tires affect vehicle stability, heat buildup, braking, steering/cornering, suspension loading, and tire failure/blowout risk. After discovering the mismatch, the concern was reported to the…

The vehicle displayed a low coolant warning and the coolant reservoir was low. Audi dealer service records dated on or about 02/14/2025 document the concern as: “client states low coolant warning was on, coolant reservoir is low, diagnose and advise.” The dealer performed coolant-related work involving the thermostat gasket / coolant hoses or connections to the coolant reservoir, ran the vehicle to operating temperature, and rechecked. The concern is being reported because the coolant…

The rear-view camera intermittently fails to engage when the vehicle is shifted into reverse. When the camera does display, the image sometimes shows horizontal glitch lines/artifacts. This affects backing visibility and parking safety and creates a risk of collision with pedestrians, objects, vehicles, or property. The concern was reported to Audi service along with other electrical/driver-assistance symptoms, suggesting a possible camera, wiring, module, signal-processing, or broader…
