The 1991AUDI100 carries 11 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 3 crashes, 0 fires, 2 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 1991 100 is power train:automatic transmission with 2 filings, followed by vehicle speed control (2) and electrical 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 1991 100. 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.

19990724VEHICLE SPEED CONTROL
THE CAR IS CURRENTLY NOT SAFE TO DRIVE. ON JUNE 25TH I DROVE THE CAR FOR 40 MINUTES ON THE HIGHWAY. WHEN I EXITED THE HIGHWAY, THE ENGINE WOULD RACE WHEN I CAME TO A STOP LIGHT. THE BRAKES WERE APPLIED AND THE CAR WAS AT A COMPLETE STOP, BUT THE ENGINE WOULD RACE SO THAT THE SPEEDOMETER REGISTERED 50 MILES PER HOURS. WHEN I RELEASED THE BRAKES TO PROCEED THROUGH THE LIGHT, THE CAR IMMEDIATELY SPED OFF AT NEARLY FIFTY MILES PER HOUR. I DID NOT APPLY THE GAS PEDAL AT ALL. I HAD NO CONTROL OVER THE CAR. IT WAS NOT SHIFTING INTO LOWER GEAR. IT WAS RACING, EVEN WHEN THE CAR WAS PUT INTO PARK. SINCE THAT TIME, I HAVE TRIED TO START UP THE CAR ON SEVERAL OCCASIONS. EVERY TIME THE ENGINE RACES AS SOON AS THE CAR IS TURNED ON. WHEN IN PARK THE SPEEDOMETER REGISTERS UP TO 60 MILES PER HOUR AND MUST BE IMMEDIATELY TURNED OFF. I CANNOT DRIVE THE CAR. I CALLED AUDI TO COMPLAIN, BUT THEY INFORMED ME THAT THERE HAD NOT BEEN A RECALL FOR THIS PROBLEM ON MY MODEL. OTHER AUDI OWNERS HAVE TOLD ME THAT TH
