I own an Audi 2015 S5 Cabriolet. I bought this new from Strong Audi in Salt Lake City. On September 2, 2022, I was driving it on I 15 south of Provo UT. I was in the middle of 5 lanes of traffic all driving approximately 80/miles per hour. Suddenly, the engine shut down. Thank God the drivers around me were able to avoid me as I had to coast to the right lane at very slow speed. As explained by the service representative at Strong Audi my vehicle has a tendency to vapor-lock in high temperatures resulting in the engine shutting down! He further explained that parts were available for $ 2,200 to correct the situation, but since my vehicle was out of warranty this would be my responsibility. I am of course having the work done.
