What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I received no warning lights. The dealership's inspection from the previous week did not detect anything either. It is a safety concern to drive not knowing how much gas one has. I suspect the gas gauge has an issue. The sensor is in the fuel tank hence the suggestion to replace the whole tank at a cost of $3880!
Vehicle was inspected at 50,000 miles by the dealer and report says that passenger side motor mount was leaking. They also said that the motor mount will deteriorate rapidly and will affect the safety of the vehicle.
Audi Presense kicked in so violently on the 280E freeway towards NYC from Northern NJ, that my 15 y/o son now has a significant cervical spine injury, necessitating medical evaluation and treatment.
The front passenger airbag light goes on and off randomly whenever if there is someone sits at the front passenger seat. The problem is exactly same as described in Recall 21V874000. Audi A4 2019 is on the list of recall, but my car wasn't been recalled for no reason.
On May 24, 2021 I brought my 2019 Audi A4 in for service due to an error message stating, "Front parking aid: malfunction! Obstacles cannot be detected". I purchased the car in December 2019 from the dealership in Burlingame, California.
