What owners report
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 vehicle, and it now has about 84K miles on the OD.
Component/System: Passenger Occupant Detection System (PODS) / Airbag system â Recall 74E3 / NHTSA 21V874. What Happened: The passenger airbag may switch off even when the seat is occupied due to a faulty PODS wiring connection. The warning message âPassenger Airbag Offâ appears with a chime. This is an active safety recall that was issued before I purchased the vehicle, but the recall was not disclosed at the time of sale. Safety Risk: If the system shuts off the airbag incorrectly, the passenger may have no airbag protection in a crash, creating a serious risk of injury or death.

Vacuum line has coolant due to water pump failure and over heating of engine. Whole water pump and coolant reservoir plus hoses need to be replaced before additional damage to vehicle.
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. I believe this may be a defect affecting other Audi models with similar engines, and I urge the NHTSA to investigate whether a recall or technical service bulletin should be issued. Vehicle Informat
