My car stalled. I could not moved the car. Mobile Mechanic came saw the alternator belt was broke. He repaired the Belt and Alternator. When he started the car, smoke and loud squeal came from engine. He immediately shut it off. The car has less than 60k miles. I have not driven the car as much due to travel.

My daughter was driving with her brother and a friend and stopped at an intersection on red signal. The car stopped and would not start. Definitely the safety of the passengers and the people behind were put at risk because of stalled car due to engine failure at a busy intersection. It is a 2018 model and followed the Audi's recommended maintenance schedule. Check engine light was on few days before and diagnosed to be a failure of a sensor by an independent service center and was waiting to get the part. After the incident the car was towed to the dealership and they have diagnosed to be low engine compression and needs engine replacement.

The vehicle is burning and consuming too much oil too quickly between oil changes. Oil pressure light keeps turning off and on even when there is oil. Vehicle has been serviced and worked on by Audi dealership. Currently vehicle is at Audi for exact same issues after Audi claimed to fix it. Vehicle had to be taken back to the dealer for repairs within 30 minutes after picking up the vehicle from dealership for the same light. Paid $2300 for the first time I took the car in for repairs and I had to take it back cause nothing was fixed
