Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2015 S5 is steering with 1 filings, followed by engine (1) and fuel/propulsion system (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 9 investigation files overlapping the 2015 S5. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.

MY 2015 AUDI S5 IS GETTING FAULTS ON THE STEERING AFTER DRIVING IN THE RAIN ONE NIGHT WHILE DRIVING A RED LIGHT TURN ON AND HAD LOSE ALL POWER STEERING AND WAS NEARLY UN-DRIVABLE. DESCRIPTION NHTSA RECALL NUMBER THE AFFECTED VEHICLES HAVE ELECTRIC POWER STEERING ASSIST SYSTEMS THAT MAY SHUT DOWN AS A RESULT OF A STEERING MOTOR SENSOR FAULT (WHICH COULD ONLY OCCUR WITH VERY COLD AMBIENT TEMPERATURES). IF THE VEHICLE EXPERIENCES A LOSS OF POWER STEERING ASSIST, EXTRA STEERING EFFORT WILL BE REQUIRED AT LOWER SPEEDS, INCREASING THE RISK OF A VEHICLE CRASH. 15V452
