The 2009AUDIA4 carries 150 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 7 crashes, 7 fires, 3 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2009 A4 is engine with 44 filings, followed by air bags (32) and steering (15). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 2 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 9 investigation files overlapping the 2009 A4. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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 wh
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.
