AUDI Complaints

The ADAS is not working properly. Adaptive cruise control, emergency assist, lane departure, active front assist, distance warning, traffic sign recognition, adaptive light, etc. are all not working. The check engine light is illuminated, the key fob would not open car (not a battery issue) and the seat belt tensioner is not working properly. Those ADAS features are there for a reason and that is to enhance the safety of me, my passengers and other drivers. The key fob allows quick access to my vehicle, which enhances my safety when alone or with others. The seat belt tensioner provides restraint during an accident so neither I nor my passenger will go head first into the windshield, air bags and/or steering wheel/dashboard. The problems have been confirmed with the dealership. Yes, it has been inspected by the dealership. Yes, they first appeared January 2025. My car is currently at the dealership supposedly waiting for a backordered seat belt tensioner. It has been at the dealership for 22 days and I haven't any idea of when I will be getting the vehicle back. I purchased it in October 2025. It has been driven less than 5,000 miles.

Audi A5 Quattro Purchased new 06/2025. Dealer = Audi Lakeland 1215 Griffen Road Lakeland, FL 33805 Phone: (863) 284-0880 Contact = Service Manager Gary Downey Tire = Bridgestone Turanza LS100 235/45R18 98H REO (Extra Load) Run Flat Tire Tire also includes “Enliten” - don’t know if that is part of model name Brought vehicle in to Dealer for first oil change at 9,006 miles on odometer. Dealer inspected tires and reported both front tires were Red/32” and 2 rear tires were yellow at 5/32”. At 9,000 miles, this is obviously grossly premature tread/tire wear. For front tires to be unsafe to drive at fewer than 9,000 miles is unexpected and others need to be made aware of the risk of premature tread/tire wear to avoid dangerous blowouts that could result in accidents and injury. Feel lucky to have brought vehicle in 1,000 miles early for oil change and for Dealer to have detected. Dealer replaced all 4 tires at no cost and tires are being shipped to Bridgestone. I have Dealer service technician video showing tire/tread wear but was unable to download here — perhaps due to length. Happy to forward if you want it.

I had 93u9 criteria 04 recall done in February. As of March 6, I had a no power supply message. Without being able to charge it went to the dealer. They said it was the charge port assembly but not from the recall since that was software. Once that was fixed they charged the car and it immediately had the fault electrical malfunction. Now they say i need to replace the rear drive motor. Then thy called again and said the 12v battery needs to be replaced as well. This all happened while still at the dealer. I didn’t have those faults prior, yet they want to say none of its related. This appears all related. After I got the car back from the recall, I had two times the charging didn’t want to start, then I had ghost wiping with the rear wiper and the infotainment system rebooted several times while driving. Safety had gotten much worse and now there are cascading failures. Audi does not want to admit the recall was the cause, but the car had no issues prior and now a month later had $17000 in repairs. Audi has had the error code reports requested by me, but they have not provided them including the corporate office. I feel this recall caused a catastrophic failure of my battery and electrical system.

CHARGING SYSTEM DEFECT: The manufacturer-supplied portable charger (rated 9.6kW at 240V/40A) delivers only 7.4kW — a 23% shortfall. The authorized dealer confirmed this measurement in March 2026 but refused to repair, stating "no issues." The charging rate also degrades over time without manual reset. The vehicle also intermittently fails to charge at DC fast charging stations — it begins charging, then stops within minutes displaying "Malfunction of charging" error. Other EVs charge normally at the same stations. SAFETY RISK: Charging failures create a stranding hazard. The vehicle can fail to charge at public stations without warning, leaving the driver unable to complete trips. REPAIR HISTORY: 5+ visits to two authorized dealerships over 10 months (May 2025–March 2026), 16+ days out of service. No fix — returned each time as "no fault found" despite video evidence of failures shown to dealer at every visit. Manufacturer corporate support also failed to resolve. Dealer found DTCs for charger communication faults. A demand letter was sent to manufacturer — no response received. Vehicle and charger available for inspection.

Vehicle experienced a sudden and total loss of propulsion while driving due to an internal failure of the rear electric motor. The dealer diagnosed it as 'coolant intrusion' into the motor unit. This is a known manufacturing defect in the 2019 e-tron (TSB 2073858/2) where internal seals fail, allowing coolant to destroy the motor. This created a high safety risk on the highway. Audi is refusing to honor the 8-year/100,000-mile High Voltage System Warranty, citing a lack of routine maintenance, even though the motor is a sealed unit with no user-serviceable internal seals

The Seat Occupancy Detection System is malfunctioning. The passenger airbag warning light activates when a passenger occupies the passenger seat and the passenger overhead reading light remains on when the seat is occupied including overnight. These are established symptoms of Seat Occupancy Detection System failure. The manufacturer issued a warranty extension specifically covering this defect for 10 years and unlimited miles. When the vehicle was presented at an authorized dealer for diagnosis and repair under the warranty extension, the service advisor deliberately omitted the airbag warning light symptom from the repair order and inserted pre-emptive warranty denial language before any diagnosis was performed. The airbag system malfunction remains unrepaired despite an active manufacturer warranty extension covering this exact defect. The dealer’s failure to properly document and address an airbag warning light constitutes a safety concern that NHTSA should investigate.

Check engine light is on almost constantly on my car. It might turn off and stay that way for a couple of days, but always comes on again. Dealership had made two attempts to "fix" it by just clearing the faults. However, according to the service department the reason why check engine light came on was "faults for loss of communication to powertrain electronics and brake electronics" which i think is a real safety concern. After my last trip to the dealership the check engine light came on after just two days of normal driving. There was also a situation when i was unable to shift to park with the risk of rolling along with some other error messages on the dash. I was unable to lock the vehicle because of that and of course there was a risk of it rolling.

Start/Stop button will not start the engine at times. May take several attempts before engine will start. Had to have Audi Roadside Assist come to my location to get the vehicle car started. Drove vehicle to nearest dealer with the "engine light" illuminated. Was advised that Audi has a software update that needs to be installed. Update was supposed to drop by week 10 of 2026 but it is still not available as of week 12. Audi and the dealer cannot provide a resolution after vehicle has been in shop for 3 weeks. Was told that I could pick up the car since they did not see it as a safety issue, but if the vehicle if often unable to start why would one trust driving it?

The contact owns a 2022 Audi A4. The contact stated that while driving 70 MPH, the vehicle stalled in the middle of the roadway and failed to restart. There was no warning light illuminated. The vehicle was towed to the used car dealer where it was purchased. The dealer diagnosed the vehicle with engine failure and stated that there was a hole in the engine block. The contact was referred to an Audi dealer for a diagnostic test. The vehicle was towed to the dealer, where it was diagnosed, and it was determined that the engine needed to be replaced. The contact inquired about the cause of the engine failure, and the contact was informed that a thorough diagnostic test had not been completed. The vehicle was not repaired. The dealer submitted a claim for Goodwill Assistance to the manufacturer; however, the claim was denied. The contact related the failure to NHTSA Campaign Number: 22V753000 (Engine and Engine Cooling); however, neither the VIN nor the model vehicle was included. The failure mileage was approximately 51,155.

The contact owns a 2013 Audi A3. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly went into LIMP Mode with the check engine warning light illuminated. The contact stated that the glow plugs failed to function and became inoperable. The vehicle was taken to several dealers, where it was diagnosed with exhaust system failure. The contact was informed that the exhaust system needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 128,000.
