Verdict · NHTSA data
Limited data — recalls on file
NHTSA has just 5 complaints on file for the 1990 Audi 90 — too few to judge reliability from owner reports alone — but 3 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME AIR BAG SENSORS DO NOT COMPLY WITH AUDI'S DURABILITY STANDARDS OVER THE LIFETIME OF THE VEHICLE.
Consequence
IN THE EVENT THE SENSOR SHOULD MALFUNCTION, THE AIR BAG RESTRAINT SYSTEM CAN INADVERTENTLY DEPLOY. DEPLOYMENT OF THE AIR BAG RESTRAINT SYSTEM WITHOUT WARNING COULD CAUSE A DRIVER TO LOSE VEHICLE CONTROL.
Remedy
DEALERS WILL REPLACE THE AIR BAG SENSOR CONTROL MODULE.
Defect
THE DIFFERENTIAL OIL OF THE TRANSAXLE IS LOST OVER TIME DUE TO EVAPORATION. LOW OIL LEVELS CAUSE PREMATURE BEARING AND GEAR WEAR AND EVENTUAL FAILURE OF THE DIFFERENTIAL.
Consequence
IN THE EVENT OF FAILURE, THE VEHICLE'S DRIVE WHEELS COULDLOSE POWER. IN EXTREME CIRCUMSTANCES, THE FRONT WHEELS LOCK, CAUSING RAPIDDECELERATION RESULTING IN POSSIBLE LOSS OF VEHICLE CONTROL AND AN ACCIDENT.
Remedy
DRAIN AND REPLACE THE DIFFERENTIAL GEAR OIL WITH OIL HAVING HIGHER PERFORMANCE CHARACTERISTICS.
Defect
IMPROPERLY MANUFACTURED STEERING LOCK BOLTS COULD BREAK IF DRIVER APPLIES EXCESSIVE FORCE TO A LOCKED STEERING WHEEL IN AN ATTEMPT TO DISENGAGE THE STEERING LOCK.
Consequence
BOLT BREAKAGE WOULD CAUSE STEERING WHEEL TO REMAIN LOCKED EVEN AFTER THE DRIVER TURNS THE IGNITION KEY AND ATTEMPTS TO MOVE THE CAR; THIS TOTAL LOSS OF STEERING CONTROL COULD RESULT IN AN ACCIDENT.
Remedy
REPLACE COMPLETE STEERING LOCK ASSEMBLY, INCLUDING A MODIFIED LOCK BOLT.
The record is thin — 5 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 3 recalls should be verified as completed.
