IllustrationMY LEXUS SC400 1992 HAS A CRACKED CENTER AC VENT, BAD CD CHANGER AND ALMOST ALL OF THE DASH LIGHTS ARE BURNED OUT. THESE PROBLEMS OCCUR ON ALMOST EVERY SC400 IN THE EARLY MODEL YEARS AND I BELIEVE THEY ARE DUE TO DESIGN FAULTS BY THE LEXUS COMPANY.*JB

Official recalls
192V046000 · Service Brakes, Hydraulic:foundation Components
Apr 1, 1992
THE ANTI-LOCK BRAKE/TRACTION CONTROL COMPUTER LOGIC PROGRAM WAS INCOMPLETE, RESULTING IN THE TRAPPING OF BRAKE FLUID PRESSURE IN THE REAR BRAKE LINES. FAILURE TO RELEASE THE REAR BRAKE LINE PRESSURE CAUSES A CONDITION WHERE BRAKE PEDAL APPLICATION RESULTS IN ACTIVATION OF THE FRONT BRAKE ONLY, AND CONTINUAL REAR BRAKE DRAG.
Consequence & remedy
Consequence: FAILURE TO RELEASE THE HYDRAULIC PRESSURE IN THE REARBRAKE LINES CAUSES THE REAR BRAKES TO "DRAG" AND A CONDITION WHERE ONLY THEFRONT BRAKES ARE APPLIED WHEN THE BRAKE PEDAL IS DEPRESSED BY OPERATOR. THISRESULTS IN EARLY WEAR OF THE REAR BRAKE LINING, INCREASES OF STOPPING DISTANCES,AND POSSIBLE LOSS OF VEHICLE CONTROL AND A POSSIBLE ACCIDENT.
Remedy: REPLACE THE DEFECTIVE ANTI-LOCK BRAKE/TRACTION CONTROL COMPUTER, AND IF ANY BRAKE SYSTEM IS DAMAGED FROM THE DEFECTIVE OPERATION OF THE ANTI-LOCK BRAKE/TRACTION CONTROL SYSTEM, REPAIR THE DAMAGE AT NO COST.
