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. Im 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 vehicles issue and they know it. Its extremely predatory, after further investigation and research Audi dsnt 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.
