Airbag pressure sensing fault in passenger seat. Fix is $1,800

NHTSA ID 11695232 · filed Oct 23, 2025

For recall 21V198-69BY, I took my car to Audi of Birmingham on recall. They provided me a service form to show the repair had been made, but my passenger side air bag off light is still on because they didn't make the repair. It wasn't brought to my attention until I took my car for another repair job and the didn't make that repair, either.

Smelt like something was burning and the smell was coming out of vents. Looked online and found that people have been having issues with the auxiliary heater for the HVAC to help the car warm up faster. I check mine and found that the connector was staring to melt. Seems like it could be a potential fire hazard if not caught soon enough.

NHTSA ID 11702870 · filed Dec 3, 2025

My 2015 Audi A3 1.8T is experiencing the exact same failure symptoms and operational hazards as those described in Audi’s own Warranty Extension U49, which covers certain 2017 and 2018 Audi A3 and A3 Cabriolet 2.0 TFSI models. According to Audi’s bulletin, vehicles with faulty mechatronic units are eligible for replacement under an extended warranty due to safety concerns — sudden loss of drive, vehicle being stuck in neutral, and PRNDS flashing while in traffic. My vehicle is now exhibiting these identical symptoms: (1) Sudden disengagement of all gears while driving when it tries to go to fourth gear. At this point, there is a (2) flashing PRNDS indicator and “Reverse Gear Not Available” message. (3) Loss of ability to accelerate in moving traffic, requiring emergency maneuvers, and halting traffic. (4) Temporary restoration of function after shutting off and restarting the engine, only for the problem to happen again. (5) Check Engine Light. This is a serious safety hazard that puts both the driver and other road users at risk. The only reason my vehicle is excluded from the coverage appears to be its model year (2015), despite the fact that the mechatronic unit and failure mode are identical to the covered 2017–2018 vehicles. I believe Audi overlooked this issue in other year models and, as such, I respectfully request that the NHTSA investigate why Audi is limiting this safety-related repair to only certain VIN ranges and model years, when vehicles just a couple of years older are exhibiting the exact same dangerous defect. A sudden loss of propulsion at highway speeds is a serious risk that warrants broader manufacturer accountability. The company should fix this issue as soon as possible.

NHTSA ID 11695232 · filed Oct 23, 2025

Subject: Complaint regarding refusal to perform recall repairs outside the U.S. – VIN [XXX] Dear NHTSA Office of Defects Investigation, I am the owner of an Audi A3, model year 2015, VIN [XXX] . According to the NHTSA database, my vehicle is subject to two open recall campaigns: – 69BY / 21V198 – Passenger Occupant Detection System (PODS) – 20YF / 24V110 – EVAP Suction Pump I currently reside in Ukraine, where the vehicle has been legally imported and registered. Despite the recalls being active and safety-related, the official Audi importer and dealers in Ukraine have refused to perform the repairs free of charge. They argue that these recalls apply only to the U.S. market and therefore decline service, which contradicts the global principle of mandatory recall repairs. This situation puts me and other drivers at risk, as the unresolved recall issues directly affect vehicle safety. I kindly ask NHTSA to review this case and provide guidance on ensuring that recall obligations are respected internationally, or to instruct Audi AG / Audi of America to facilitate the execution of these recalls regardless of the vehicle’s current market. Attached, please find copies of my correspondence with Audi dealers in Ukraine and Audi of America. Thank you for your assistance. Best regards, [XXX] Ukraine Phone: [XXX] Email: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Dear NHTSA, I am filing a complaint about the handling of a recall repair on my 2015 Audi A3 (VIN: [XXX] ) for the suction jet pump. The service experience has been frustrating and raises concerns about the repair’s quality. 1.First Visit - Inadequate Information: During my first visit to the service center, over an hour away, I was turned away because my fuel level was too high. I was never informed that my gas tank needed to be below a certain level for the repair, resulting in wasted time and travel. 2.Second Visit - Check Engine Light Still On: On my second visit, the suction jet pump was supposedly repaired, but my check engine light remained on. I had informed the service advisor that the light was related to an EVAP system malfunction, which I was told could be caused by a faulty suction jet pump. After speaking with multiple mechanics, I learned that a malfunctioning suction jet pump could cause fuel to enter the EVAP system, damaging parts like the purge valve or charcoal canister. 3.Unreasonable Charges: The service advisor insisted that the remaining EVAP issues were unrelated to the recall and wanted to charge $220 for another diagnostic and repairs, without even inspecting the car after the recall service. This seems unfair, as there’s no way to confirm without a proper check. 4.Missing Seat Belt Buckle: After the recall service, I discovered that the rear driver’s side seat belt buckle was missing. This is a major safety concern and needs to be addressed. I request NHTSA’s help in investigating the repair quality and ensuring these issues are resolved fairly. Thank you for your attention.

Blown turbo with propeller broken off lodged into the pre-catalytic converter, which caused damage to the catalytic converter/exhaust requiring a new turbo and a complete new catalytic converter and exhaust system. They also found major oil leaking from the upper timing cover gaskets, which I later found documented on the accounting service record as not repaired at that time few months from my purchase. These known engine damages were a major contributor to the engine failures that I’m faced with today. Oil starvation from known oil leaks, damaged gaskets, and failing parts caused oil starvation of the turbo, constant overheating with coolant and oil problems since purchasing the car and which ultimately froze the turbo and snapped the propeller. I’m still struggling without an operating vehicle for over a year, and trying to afford these expensive repairs, which should’ve been covered under the 15 year PZEV warranty and/or recalls of these known parts failures. It was at the dealership in plenty of time for the SMOG certification, which was the sole reason for the appointment and it being at AudiSD, which they refused to do. These are extremely expensive repairs, these are known issues with several class action lawsuits and recalls behind them, yet they simply refuse to take ownership, deny any support, and making excuses for their lack of responsibility. I asked several times for them to do the right thing, take the car back and refund my money or give me an equivalent car to what I was promised when I purchased it, they refused and no management has been involved. I deserve to be compensated for my time over the last several years dealing with these repeated issues, compensation for all the parts I have been forced to buy, refunded the amounts I’ve paid for technicians to truly diagnose the problem and for the repairs I’ve yet to be able to afford, as well as the towing and other charges I have incurred as a result of purchasing this vehicle from AudiSD

The plastic roof trim panel on my 2015 Audi A3 is peeling and deteriorating significantly. This is not painted metal—it’s a separate, non-paintable plastic component that runs along the sunroof and roofline. The surface began flaking and lifting over time, and multiple independent body shops confirmed the panel is failing structurally and cannot be refinished—it must be replaced. While this may appear cosmetic, it’s not. The panel helps protect the roof seam and substructure. Its failure opens the door to water intrusion, corrosion, and potential roof integrity compromise—a serious safety concern, particularly in the event of a rollover or high-impact collision. Other owners of vehicles built on the same MQB/8V platform—including the VW Golf and SEAT Leon (not sold in the U.S., but structurally similar)—have reported identical issues, often followed by cracking or detachment of the panel. Despite multiple attempts to resolve this, Audi of America has been largely uncooperative. Their warranty process requires a diagnosis from a dealership, but most Audi dealers do not perform bodywork and refer customers to third-party shops—whose assessments Audi then refuses to accept. I’ve been left in a loop with no meaningful support, despite the issue being widespread and well-documented. I believe this is a design or materials defect that should be reviewed before it leads to broader safety or structural failures. See the below URL's for similar issues.

Consumer bought this car at 30,040 miles. The car currently sits with 89,000 miles. I have had 18 recommended service visits totaling $19,240 and then on July 15, 2022 with no pre indicators or warnings the engine dies after a 95k full multipoint inspection that consumer had 3 weeks prior. The car has an impeccable Maintenace record. I did everything the dealer told me; and I still almost died on the 101 fwy going 70 mph on a conference call; the flashers didnt even work; the car dead and came to a hard halt and trucks were screeching around me with smoke coming from their tires because of the extreme hard stop and slamming on breaks, i was screaming for my life praying no one would slam into me. Metro who roams the fwy saved my life; without him i would be dead because of AUDI's HORRIBLY MANUFATCTURED VEHICLE. It seems as though the dealer purposefully sabotages my car as a woman; i have no alternative but to fix it and now they want $27,000 MORE for a new engine AND starter. so, in total; to drive 57,000 miles I've paid $37,000 cash for the car (I own the title)/ plus $19,240 in maintenance /repairs and now they want another 27,000 for the engine. i have no more money to give them. i recently returned my 3rd rental vehicle and i am out of funds on transportation.
