NHTSA Complaint #10817739 — 2003 TOYOTA SEQUOIA

VEHICLE STABILITY CONTROL (VSC), TRACTION CONTROL (TRAC), AND ANTILOCK BRAKE SYSTEM (ABS) DASH LIGHTS CONTINUOUSLY ILLUMINATED INDICATING THAT ALL SYSTEMS ARE OFF OR MALFUNCTIONING. CAN CONFIRM THAT THE TRAC, VSC, AND ABS ARE INACTIVE ALL OR MOST OF THE TIME. THE ABS INTERVENES AT RANDOM UNDER NORMAL BRAKING CONDITIONS WITHOUT CAUSE AT LOW SPEED (LESS THAN 20MPH) AND MAKES BRAKING DIFFICULT AND INCONSISTENT IN CONDITIONS WHERE ABS IS NOT NORMALLY NEEDED. IN THAT SITUATION THE BRAKE PEDAL BECOMES HARD TO DEPRESS AND BRAKING FORCE IS INCONSISTENTLY APPLIED WITH LITTLE CONTROL GIVEN TO THE OPERATOR IN TURN EXTENDING THE BRAKING DISTANCE WITHOUT DUE CAUSE OR WARNING. AFTER MUCH RESEARCH ONLINE I HAVE FOUND NUMEROUS REPORTS STATING IDENTICAL AND/OR SIMILAR OBSERVATIONS AND EXPERIENCES. IT IS MY OPINION THAT THE PROBLEM LIES IN THE VSC CONTROL MODULE, A KNOWN PROBLEMATIC COMPONENT ON THIS GENERATION OF SEQUOIA AND MORE SPECIFICALLY MODEL YEAR 2003 VEHICLES. A RECALL FOR THE VSC SYSTEM WAS ISSUED IN APRIL/MAY 2010 UPGRADING THE CONTROL LOGIC OF THE VSC SYSTEM IN CERTAIN MODEL YEAR 2003 VEHICLES. LET IT BE KNOWN THAT THE VEHICLE IN QUESTION HAD THE RECALL WORK DONE IN JUNE OF 2011 WHICH DID NOT REMEDY THE ISSUE AS IT HAS BEEN EITHER INTERMITTENT OR CONSTANT SINCE THEN.
