“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. …”
