Verbatim excerpts from NHTSA complaints, by component
Fuel/propulsion system
4 reports
“I am reporting a recurring fuel system defect affecting my Audi Q3, consistent with Safety Recall 20YF – Suction Jet Pump. The problem began as difficulty refueling and now mirrors an identical issue I experienced with a previous Audi A3, which ultimately leaked fuel severely both while driving and when parked. That incident put me and my passengers in danger and caused breathing difficulties from fumes. The Q3 now shows the same early signs — gas pump shutoff, failed refueling attempts, and multiple $200 credit card holds at stations without fuel entering the tank. Audi replaced the tank in 2024, but the issue returned. This is not an ordinary maintenance issue — it is a serious safety hazard. Audi’s solution has been to keep replacing the part, while denying a vehicle replacement or compensation. They redirected me to BBB, but I felt it was necessary to report this publicly. If the gas leak recurs, it could lead to fire or poisoning. The fuel system should not fail like this, and I want to ensure no one else faces this danger. If anything happens to me as a result, I will pursue further legal action.”

“By the dome light, it leaks water when it is pouring rain very heavily. It also drips water by the passenger side shade visor. The dome lights will dim and get brighter consistently as it is dripping. the driver side headlight also gets foggy when it rains, which causes the one side of the vehicle not being able to see out from. The rain in the inside goes near the electrical outlets and sometimes gets into it, if i dont wipe the water away. At night time it is dangerous, with the lights dimming & getting brighter , while also leaking from the top as I have to dry it, try to turn the lights off and drive at the same time. No specific date this has occured, it has happened for approximately 3 months now.”

“My 2021 Audi Q3 SUV had been very dangerous to drive stalling, stopping on the highway and shuttering for about two weeks. While I was going about 70 miles an hour my vehicle stalled. It lead to me almost being killed and rear ended. My vehicle had been displaying a stop start malfunction code and check engine light. I contacted Audi USA Roadside Assistance. Paloma R. Said they would help and towed me to Audi of Jacksonville on Atlantic. I was told the diagnosis was $300 and it would go towards fixing the vehicle. However, my vehicle was not fixed properly with them charging me $300 separate from the repair. My total came to $855, they are a scam. Alex told me over the phone that the $300 would apply to the balance. This is extremely deceptive and I feel they should be investigated. I’m still out of a vehicle with no safe way to get around. As soon as I left the dealership the check engine light was back on. It began to steer, and stop turning. Audi know the diagnosis will not solve the real issue. They also included a part on the repair list that was part of a known recall. The National Highway of Safety has flagged Audi Q3 for coolant leaks and issues. They…”
