FUEL/PROPULSION SYSTEM

2 complaints

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.

The car stalled while driving. There were no warning lights or indicators before the failure. The car was unable to be restarted so it was towed to a mechanic. It was discovered the car was out of gas however the gauge read there was still a lot of gas in the tank. We then took the car to an Audi service center and they informed us it was one of the gas tank sensors that was faulty. They replaced the first sensor and charged us $1k and that didn’t fix the problem so they contacted Audi and were told it was a faulty second sensor inside the gas tank and the only fix is to replace the whole tank. We opted not to replace the tank at this time. After further research I found that the sensor we had replaced is recalled on other Audi models of the same year recall #22V155 I believe more investigation and recall is needed to include the Q series Audis as well as further investigation into the gas tanks internal sensor that requires a replacement of the whole system.

ELECTRICAL SYSTEM,EXTERIOR LIGHTING,UNKNOWN OR OTHER

1 complaint

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.

ELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE

1 complaint

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 quoted $657 for a part that would have been covered under a recall. I have a service bulletin. The real issue is listed as a turbo charge replacement which is $3,300. That will not fix my vehicle’s issue and they know it. It’s extremely predatory, after further investigation and research Audi doesn’t have a remedy for the stop start malfunction. Which cause engine failure and a dangerous driving hazard. Audi Of America knows the service will not fix the main problem of the stop/start malfunction. Even after $6,500 worth of repairs its false claims and most importantly a waste of money.

1 complaint

I was traveling approximately 50 mph on a highway when we were rear-ended. The car spun around and we were both thrown forward due to the malfunctioning of both the driver and passenger seat belts. Further inspection found the rear seatbelts as well did not function properly. Both the driver and front passenger seats reclined and broke during the impact of the accident. The passenger sustained head injuries and had to be taken by ambulance to the hospital. The driver's left arm was injured.

SEAT BELTS

1 complaint

Two weeks ago my 2021 Audi Q3 displayed a child lock malfunction error. The rear passengers cannot open the door from the inside even after turning off the child lock feature because of this fault. I dropped my vehicle at the Audi dealership in Ontario, California. They called me a few hours later and said that they fixed the malfunction by doing a software update. The next day the fault alert came back. My parents are over 80 years old and I'm concerned that if I get in to an accident my family members will get stuck in the back

While merging onto the highway, there was a loud bang and the overhead lights as well as driver door alert on the dashboard came on. Upon checking, the front driver door had popped open on it's own.

LANE DEPARTURE

1 complaint

I was driving down a one lane road in my car that is less than a month old, when all of a sudden my car aggressively veered to the right over the shoulder line, then it veered to the left over the yellow line and then the right again and it kept going over the line down a slight embankment into the woods about 30 feet. All the while the steering and brakes completely failed and would not work and the car was beeping. The only thing that stopped me was hitting a boulder. I kept trying to brake. My foot was pressed all the way down to the floor and it would not stop. It was terrifying. There was a witness who told me I must have had angels watching over me as I was not injured nor was anyone else. If anyone was driving in the opposite direction I could have hit them head on. If I was on a two lane or more road or on a bridge or a highway, it could have been tragic. Clearly there is a mechanical or electrical defect. The car was completely out of my control. Audi of America obtained the data recorder and investigated. They have not found any defects and deny responsibility. This is impossible. The brakes and steering did not work and the car was swerving for no reason. Even the witness attested to this.
