Air bags

24 reports1 crash2 related recalls
“Audi had a recall on my 2018 A3 for a Passenger Occupant Detection System. in July 2023, Audi replaced the PODS Sensor mat. Recently, the same car has encountered the same issue. The PODS light indicates the airbag is off even if a passenger is sitting in the seat. There has been not repair work since July 2023, that would impact the PODS. And the warning lights reappeared after a period of normalcy. I feel this is an incomplete recall remedy and Audi is now wanting to charge me for the repair”

Fuel/propulsion system

5 reports
“Hello, I dropped my car off at Audi and Dominion in San Antonio Texas on Thursday July 10th for a repair this was a recall for the fuel pump system in something in the mechatronic controls. They had my car until Saturday I was informed that the repairs were done under warranty. Then on Saturday July 19th as I began to drive the vehicle a alert for my transmission malfunction appeared on my dashboard and I Lost first gear. I had my car taken to Audi on Dominion where I was informed by several service staff that this is a common malfunction after the last software update that was done the week prior and that it could take up to 48 hours to do the repair and recall warranty work on my vehicle. Audi on Dominion has had my vehicle for 5 days and has not given me an answer as to know whether or not the repairs will be approved as this is covered under my extended warranty. My car was working perfectly fine until I was forced to take it in for this recall of which Audi has failed to provide a loaner vehicle or give accurate information as to whether or not the repairs will be covered. I have been informed that I will be responsible for the cost of the repairs. These…”

Electrical system

5 reports
“The vehicle pre-sense stopped the vehicle due to the detection of an object however, there was no object. This happened going forward and in reverse multiple times, causing the car to come to a sudden, abrupt stop even at speeds in excess of 30mph. This resulting in my teen daughter having bruising from the seat belt. The car was taken to the dealership and the dealership recalibrated the control unit. The vehicle continues to unnecessarily activate pre-sense when in reverse, and causes the car to come to an abrupt halt despite there being no object. The system may be responding to shadows. Numerous returns to the service department continue to yield “no codes”. The PODS system was recalled and this is a related system.”

Engine

4 reports
“Coolant Water Pump and Thermostat -- Coolant temperature indicator gauge runs from normal to high after about 10-15 miles drive. Coolant levels are good and no signs of leak. Engine light is activated along with warning messages. Engine Warning: Drive System Malfunction. Please call for service. The vehicle goes into "Limp Mode" and warns to not exceed 4,000 rpm. I am in the process of having this repaired by a mechanic. FYI--- There was a previous RECALL for this in 2017. Clearly the problem still occurs.”

Tires

4 reports
“225/45-R18 DOT(17/22) On September 6, 2025, I purchased a 2018 Audi A3 (VIN [VIN], 56,634 miles) delivered by Carvana. Within days, I had the vehicle inspected at multiple independent repair shops. Each shop documented that all four tires showed dry rot and cracking and advised immediate replacement due to risk of tire failure. On September 10, 2025, I contacted Carvana and followed their warranty claim process. After escalation, on September 18, 2025, I was informed that Carvana determined “the tires are not bad enough” and denied replacement. The vehicle was delivered with unsafe tires that pose a serious risk of blowout or loss of vehicle control, endangering both the driver and others on the road. DOT date codes and photos of the cracks confirm the condition of the tires at the time of delivery. This complaint is being filed so NHTSA is aware of the issue and to request investigation into Carvana’s sale of vehicles with dry-rotted, unsafe tires.”

Power train

4 reports
“I was driving on the freeway at 60 mph when I received a warning code of a transmission problem. The code said the car was driveable but I should take it in for service. About 1-2 minutes after that the car lost all power. Unfortunately I broke down in the left lane in a construction zone without a shoulder. The state patrol had to temporarily shut down all three lanes of the highway to push me out of the traffic lane I was blocking. That was unsafe for me and for the state patrol and for the tow truck driver. The car was up to date on all recommended service, had been acting normally until the moment it failed, had not given me any warnings and is only 6 years old. I had the car towed to the dealer and the dealer reported that the Mechatronic unit (transmission computer) failed. Replacing the Mechatronic took a week and cost $5000.”
