Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Crash reported

As I was pulling into a parking spot, traveling at a low speed I naturally applied the brakes but the car accelerated instead jumping a concrete curb and hitting a wall. In that moment I realized I had no control of the vehicle. This sudden unintended acceleration was accompanied by a loss of braking. Pressing on the brakes harder did not stop or slow the car. Brake and accelerator failed. The vehicle is available for inspection. Thankfully the car hit a wall, and there was no injury to myself or others. The parking spot is positioned in front of a concrete wall. The problem has not been confirmed by the dealer as of yet. No warning lamps, message or other signs of malfunction were evident.

The contact was advised that he had suffered carbon monoxide poisoning. The contact had the vehicle towed to a local dealer, who diagnosed the vehicle and determined that the charcoal air filter behind the driver's seat needed to be replaced.

The turbocharger wastegate actuator failed suddenly at highway speeds, causing loss of engine power and making it extremely difficult to maintain highway speeds. The warnings that suddenly appeared caused the cruise control to cease working as well. The dealership (Audi Miami South by The Collection) inspected the vehicle and confirmed the wastegate actuator seized, requiring a complete replacement of the turbocharger. The vehicle has 53,000 miles.

Owner of 2019 A4 recently purchased from dealership after lease expired in Feb.2023. Currently with only 36,800 miles, took vehicle to inspect on Nov.24th and nothing but a front light replacement and suggestion of new tires in inspection video. The factory warranty due to expire the following week, Dec. 2nd 2023, and I was inquiring as to cost of extending warranty, but di not purchase, was waiting until after holidays. The following weekend, Tank Malfunction light turns on, from nowhere and displays zero gas on the dashboard. The previous night we filled tank with superior gas from the same gas station we use, nothing odd.. Call dealership next business day, they state the factory warranty expired and cannot cover anything. I call AUDI USA and they suggest that Audi dealership service inspect and they do and after inspecting the car conclude that I need a new fuel tank! A brand new car needs a gas tank! Service advisor states I have a faulty tank and it is because of ibad gas? What is bad gas? I mean really? I put the same gas as always, superior. 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! The dealership should assume responsibility for not detecting during inspection. Even though factory warranty expired within a week of incident, they should provide a grace period. AUDI USA must investigate. I AM REGRETTING MY AUDI PURCHASE!!! This sensor is faulty and is dangerous and I am not the only owner who has this problem occur. It is unacceptable that this car not perform as expected and gas tanks usually have a 20 year life span! I believe that 46,000 cars were recalled with gas gauge issues and although this car is not in that recall does not mean it can be defective.

1 injury reported

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 brakes were so abruptly applied by Presense that we thought we had been hit by a car, but had not been in an accident. This is very dangerous, and now my son is injured, despite no accident occurring.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
