2017 Audi A4

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.

Audi A4 Water pump and Thermostat failure. VW/ Audi USA had a recall on this issue for several models including the Audi A4 models thru 2016. My car was built in 2016 with model year 2017 and according to the recall my car did not qualify. Since then there has been several Class Action Lawsuits for this same issue. I was fortunate I discovered the leak while the car was parked in my garage and wasn't on the freeway. It seems that VW/Audi USA hasn't corrected this issue leaving many people in danger of a possible breakdown and a premature costly repair. In addition, I was denied the Class Action Lawsuit extended warranty by 3 months. So this premature costly repair was on me. Thank you for all you do to keep us safe.

Randomly, sometimes multiple times in a 30-60 minute time window while driving, the media center turns itself off and reboots. While driving with the navigation system or other key functionality of this system (phone connectivity, radio, etc) the driver suddenly has lost the current connection that was in use. As for the navigation or phone connection, this disconnection could result in a sudden dangerous situation. The manufacturer knows of this “bug” and has a software fix, but charges any customer whose vehicle is not still under warranty to diagnose and fix it.

Every time I start the car, a message comes on saying that the passenger airbag is off even when I have an occupant next to me. I spoke with the dealer and he told me that this recall was claimed and fixed in 2022 in Texas by the previous owner but I replied that the problem continues and he told me that this was no longer an Audi problem. Furthermore, every time it accelerates over 40 miles per hour, a message about the driving system in malfunction appears and also the automatic on and off system at stops stops working and when I drive it at low speed there is no problem. I took it to Audi and they told me that they should change the turbo and I told them that the car only has 100,000 miles and why they should change a turbo that only has 100,000 miles of use and they told me that’s how it is

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.
