The contact owns a 2015 Audi A3. The contact stated that the dealer had previously repaired the vehicle under the federal safety agency Campaign Number: 24V110000 (Fuel System, Gasoline); however, the vehicle was not driven until a year later after the recall repair due to medical issues. The contact stated that while refueling the vehicle, fuel was backing up in the fuel filler neck. Additionally, while driving at an undisclosed speed, the vehicle stalled and failed to exceed 30 MPH. There was a fuel odor coming from the vehicle, and the fuel and check engine warning lights were illuminated. A family friend diagnosed the vehicle and determined that the suction jet pump had failed. The dealer was made aware of the failure. The manufacturer was notified of the failure by phone and email. The failure mileage was approximately 94,242.

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 federal safety agency 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.

Since 2021-2022 I have had several issues with my reservoir tank. This tank holds my coolant and has leaked continuously. They had a settlement for this problem but omitted the a3. I paid Audi dealership $ 1,600.00 to fix the problem a few years ago and have been having the same problem ever since. A few months after I paid for this problem Audi had a settlement for the reservoir tank and I was denied reimbursement because I owned a a3 and a3’s were not included in the settlement but a3 ‘s still had the reservoir problem as well. I contacted Audi USA on several occasions and still have been disregarded but Audi USA wants you to pay for the diagnostic first at the dealership just for them to even look at the immediate problem. I just contacted Audi USA again 1/29/25 because now I have to put my car in the shop again to get it fixed but the coolant constantly leaks and Audi service shop wants me to pay for it and I feel that I should not have to pay for (their )problem again and the same problem over and over. At this point the coolant is pouring out like water and I must get my car to the shop immediately because the engine light comes on stating no coolant running hot and this is how the Audi cars catch on fire.Please investigate this !!!! I refuse to give Audi any more of my money when they should be held responsible. I can’t find my receipt of date and amount paid but I can get this info from the dealership. I’m tired of going in a circle with this same car issue. I want my car fix and my settlement reimbursement.

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 the federal safety agency’s help in investigating the repair quality and ensuring these issues are resolved fairly. Thank you for your attention. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine low oil light keeps coming on, the oil has been changed already, I’ve had the car for more than 7 months I haven’t even driven it over 5000 miles yet. Audi needs to fix this. The power train is also the same, some days it works okay and some days it doesn’t. The cars struggles sometimes to even reach speeds up to 50 mph.I’ve taken this vehicle to the Audi dealship as well as to a foreign certified mechanic shop. They can’t figure out the problem. The engine light should not be coming on randomly when I have fully serviced the vehicle. Audi please fix these problems.
