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.

I own a 2009 audi a4. On the Month of october 2024 my transmission failed. I towed my car to a mechanic who then replaced my transmission i picked up my car on December 11 2024 at 7 am from audi of fresno. I have had no prior issues and like always i expect a dealership to inspect a new vehicle that comes in ,as i have never been able to get work done with out them always doing their own diagnostic. Any ways . On the morning of [XXX] at [XXX] i went to pic up breakfast from carls jr with my boyfriend . As i placed my order and drove up to the window without a single warning my car engulfed in flames from the front driver side . I turned my car off jumped out called. The fire department and watched as my car continued to build flames until the fire department finally showed up.

Crash reported2 injuries reported

The negligent driver yielded to the flow of traffic without stopping. When he collided with us, the airbags (exploded) deployed so strongly that they damaged the windshield and our bodies: face, neck, etc. Our beloved Audi A4 2009 was totaled and after that we had several operations: 2 eye operations (need 2 more), dental surgeries, 3 neck surgeries ... multiple unpaid medical expenses.

On Sunday December 19, 2021, while driving home the warning light for the battery/alternator flashed on with an associated beep warning. An estimated 30 miles later all electrical and motor functions died while I was in heavy traffic. I was able to pull off onto a narrow shoulder up a steep hill and park. All functions quit, I could not come out of "Park", the emergency brake switch would not release, the emergency flashers did not function. Nothing responded. I called AAA Towing service to be taken to an Audi service repair shop. The towing service had to use a jumper to provide electrical power to release the emergency brake and take the transmission out of "park." The repair service was the "Sport Hous Reno" where the alternator and the battery were replaced. Invoice # 4791, 12-21-2021, total $1,709.12. I do not expect the battery to be covered since it is expendable. However, the alternator malfunction and this model of Audi completely dying placed me in a dangerous situation where I or my family could have been seriously injured. This is not my first Audi, I did have a similar occurrence with another model and when the battery caused a malfunction the Audi computer went in "Limp Mode" and I was able to drive slowly to the dealership. This was not the case, when the electrical system failed it did not go into "Limp Mode," it completely "Died" placing me and my car in a dangerous position.

Steering
Filed Jul 23, 2021

I bought the car recently and drove it on the freeway, on the way back home I noticed a shaking/Vibration coming from the right side of the vehicle. It made the car very hard to control and staying in one lane was almost impossible. It swerves left to right uncontrollably at random times. I haven't taken it in to any dealership or manufacturer to check it out for me, also there's no warning lights on the dashboard at all. And I believe the owner I bought it from knew of this issue but didn't let me know so I'm really just as in the Blind as well. I don't know what else to do because I can't keep driving the car with uncontrollable force and putting kids in danger or anybody else's.

DRIVING VEHICLE AND IT STARTED SHAKING. GOT THE CAR HOME AND WHEN I SHUT IT OFF AND TURNED IT BACK ON IT RATTLED AND SOUNDED LIKE METAL. I WAS ABLE TO GET IT TO THE DEALERSHIP. I HAD IT CHECKED BY MECHANIC AND HE TOLD ME THAT THE TIMING CHAIN AND TENSIONER WERE THE PROBLEM AND I WAS JUST TWO MONTHS OUT OF WARRANTY. THE NEXT DAY THE DEALERSHIP CALLED TO TELL ME I NEEDED NEW CYLINDERS BECAUSE THE CAR WOULD NOT START. QUOTED ME $7,500 TO REPAIR. I DO NOT QUALIFY FOR THE CLASS ACTION SUIT BECAUSE MY CAR DID NOT BREAK UNTIL AFTER THE WINDOW CLOSED. AUDI KNEW ABOUT THE FAILURE AND DID NOTHING TO WARN OWNERS.
