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 hazard for vehicle occupants. Audi San Diego subsequently inspected the vehicle and acknowledged the speaker trim issue. However, the dealership declined responsibility for correcting the recurring defect, stating that the recall had already been performed and was now closed. My concern is that the original safety recall remedy has not provided a lasting correction. The same safety-related component has failed again after the manufacturer’s authorized repair, leaving occupants exposed to the hazard the recall was intended to address. I am requesting that NHTSA investigate the recurrence of this defect and the effectiveness of Audi’s original recall remedy, including whether additional corrective action is warranted. The vehicle and affected components are available for further inspection upon request, subject to scheduling.

I have been trying to register my vehicle in California for several months, however, in order to do so, I need the car to pass SMOG. Initially I was told that the issue was related to an emissions sensor and that I had to drive the vehicle a few more miles to get the sensor to register properly. This turned out not to be the case. A short time later, the fuel gauge completely stopped working. I took it to an authorized Audi repair shop that told me the issue was related to a the "Fuel Tank Sending Unit". That part was replaced by the repair shop, however, the issue persisted. The authorized repair shop is now telling me that it the entire tank needs to be replaced in order to fix the issue.. I have searched and this seems to be a common issue among Audi vehicles; the sensor stops working and the gauge stops responding. Audi seems to know that this is an issue. Can this possibly be investigated.

The headlights on my 2017 Audi A4 have developed stress cracks in the headlamp housing. According to the inspection performed by an authorized Audi dealer, these cracks will obscure headlight projection and lower the visibility range at night. The dealer specifically noted there were no signs of outside influence or misuse, and the issue is likely due to internal headlight temperature, external ambient temperature, and age. This defect directly impairs visibility and makes it unsafe to drive the vehicle at night or in low-light conditions. Headlights are a critical safety system. The problem has been confirmed and documented by the Audi dealership in a written inspection report. Audi of America has acknowledged that the defect is unrelated to misuse but refuses to fully assist with repairs, despite admitting it impacts visibility. The issue is ongoing and worsens with time. There were no warning lamps or dashboard messages related to the defect prior to its discovery. The vehicle and documentation are available for inspection upon request. This is a safety concern that puts me and others at risk due to reduced nighttime visibility.

The Audi "Drive Select" transmission function switches to "Sports Mode" in rain and snow. This makes the vehicle dangerously jumpy in slippery conditions. This has happened to me (I think) three times in the last couple of years, always in rain or snow. My knowledge of the car allowed me to slowly delve into the screen functions to reprogram the transmission while driving in these dangerous conditions, but I don't know if I could always do it again, or if others might find it too confusing in the moment.

I experienced similar undesirable engine behavior on two occasions. Upon coming to a stop, the auto start/stop system stopped the engine. Shortly after, when attempting to drive away, the stop/start system attempted to start the engine, but failed; the starter briefly activated to turn over the engine, but the engine did not start and continue running. The car was left in the following condition: Engine off. Gear indicator showing "D". Accelerator pedal unresponsive. Regaining engine power required turning the car off, applying the brake pedal, turning the car on, and selecting "D" with the gear selector. This behavior occurred on two occasions on different days; once on 16 March 2024 and the first time within several days prior. Both occasions occurred before the engine was at full operating temperature, and while the car was on a slight uphill slope. Ambient temperatures were in the high 40's or 50's Fahrenheit. By luck, neither occasion resulted in an unsafe traffic condition.
