An Audi dealer has just diagnosed my 2018 S5 Cabriolet Prestige with vacuum system contamination caused by water pump failure. I had requested the diagnostic due to small coolant leaks on the engine and loss of coolant in the expansion tank. No warning lights and no overheating yet. Not yet aware of any loss of performance. I have been advised it is unsafe to continue driving the car. Dealer has quoted me $7800 estimate to repair the car. Purchased the car in 2021 as a Certified Pre Owned vehic

To Whom It May Concern, I am submitting this complaint to report a mechanical issue with my 2018 Audi S5 Sportback. Around 57,000 miles, the engine began making a noticeable ticking noise, which I have been advised is due to failing rocker arms. This issue has raised serious concerns, as it can lead to engine misfires, reduced performance, and potentially catastrophic engine damage if left unresolved. The problem appeared without warning, despite regular maintenance and no prior engine alerts.

While driving, my Audi overheated randomly, started smoking, had to be towed. Had 72,800 miles, was serviced by Audi at 70k miles and all prior recommended services. Towed to Audi dealership, quoted 29k in engine repairs, Audi could never tell me why engine overheated. Would not cover any expense because “i didn’t buy it there”. Insurance denied two claims because Audi reported it as engine failure although they couldn’t prove what happened to cause the heating, said it was one of the wo

After driving for 7 to 8 minutes less that 45 mph, a yellow warning lamp and an audible warning indicating unsafe coolant temperature displayed on the dash.

The sunroof exploded. Driving on a good quality highway (CA76), no temperature extremes, no bumps or potholes. Heard what sounded like a gunshot. Pulled over thinking it might be a tire failure, to find my sunroof severely shattered. There was no debris inside the car, other than the shattered glass itself.

My 2018 Audi S5 Prestige with 59K miles meticulously maintained by the dealer had the Suspension Warning light came on about a week ago. I brought it to my local Audi mechanic and they found the right rear spring had broken about 1/3 of the way from the base and the shock had been damaged from the spring breaking. They attributed it low quality steel being used in the springs Audi is using. Luckily it was a rear spring as I understand a front spring breaking at speed could be catastrophic.
