2004 TOYOTA 4RUNNER Traction Control System Problems

The contact owns a 2004 Toyota 4Runner. The contact stated while driving 30 MPH over a bump in the road, she heard an abnormally loud sound and the windshield shattered without impact and the sunroof panel loosened. The contact also stated that the vehicle was shaking uncontrollably. The contact stated that the traction control warning light was illuminated. The contact took the vehicle to the local dealer, where it was diagnosed and determined that the subframe was rusted and needed to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 160,000.

WHILE DRIVING, THE CEL (CHECK ENGINE LIGHT) CAME ON AND THE VSC TRAC AND VSC OFF LIGHTS CAME ON AS WELL. APPARENTLY TOYOTA DISABLES VSC WHEN THE CEL IS TRIGGERED. IN MY CASE, THE 2 TIMES IT HAS OCCURRED HAS BEEN DUE TO EMISSIONS RELATED FAILURES (1ST TIME THE CAT FAILED, 2ND TIME ONE OF THE O2 SENSORS FAILED). IN THE 1ST CASE, I IMMEDIATELY TOOK THE VEHICLE TO THE DEALERSHIP AS I WAS APPROACHING THE END OF THE EMISSIONS WARRANTY. THEY MADE THE REPAIRS AND CLEARED ALL THE CODES SO WASN'T AWARE THAT THE VSC SYSTEM WAS ACTUALLY DISABLED. THE 2ND TIME (O2 FAILURE) I REPLACED THE FAILED O2 SENSOR, THE CEL HAS CLEARED, HOWEVER THE VSC LIGHTS ARE STILL ON AND VSC IS DISABLED. I HAVE SERIOUS CONCERNS THAT TOYOTA DISABLES KEY SAFETY SYSTEMS DUE TO EMISSIONS RELATED FAILURES ESPECIALLY GIVEN THE INHERENT STABILITY PROBLEMS WITH SUV'S. IF...

MY 2004 TOYOTA 4 RUNNER SKIDDED IN STOP LIGHT WHEN THERE WAS LITTLE ICE ON STREET. WHEN I TRIED TO ACCELERATE THE CAR AFTER STOPPING A STOP LIGHT, THE VEHICLE MAKES HUMMING NOISE AND SKID MAKING IT OUT OF CONTROL. IN WINTER 2009, SIMILAR INCIDENT HAPPENED ON I-69 (20 MILES EAST OF FLINT, MI), WHEN I TRIED TO ACCELERATE THE SUV AND LOST CONTROL AS THE CAR SKIDDED OFF THE ROAD CAUSING INJURY. THIS IS A SERIOUS PROBLEM AND I BELIEVE IS A DESIGN DEFECT WITH THE ACCELERATION SYSTEM. THIS MAY BE LIFE THREATENING AS I AM ALWAYS WORRIED TO DRIVE THE CAR. THIS SERIOUS DESIGN PROBLEM WITH 2004 TOYOTA 4 RUNNER SHOULD BE INVESTIGATED FOR SAFETY. *TR

WARNING LIGHTS BEGAN COMING ON AROUND 60,000 MILES OR SO. STARTED WITH THE LOW TIRE PRESSURE LIGHT & NOW HAS PROGRESSED TO THE VSC ON, VSC OFF, ABS WARNING LIGHTS BEING ON ALL THE TIME AND THE LOW TIRE PRESSURE LIGHT IS STILL ON. I HAVE TAKEN THIS VEHICLE INTO 2 DIFFERENT DEALERS TO BE FIXED FOR 40,000 MILES OR AROUND 3 YEARS WHICH AMOUNTS TO MULTIPLE TRIPS TO THE DEALER, WAITING WHILE THEY WORK ON IT OR GOING WITHOUT A VEHICLE FOR DAYS AT A TIME WHILE THEY TRY TO FIGURE OUT WHAT IS WRONG. THEY HAVE REPLACED ABS SENSORS, ENGINE COMPUTERS, BRAKES, SPEED SENSOR WIRES, RESET COMPUTERS, ORDERED NEW VALVE STEMS FOR THE TIRES. I CAN GET ONLINE & FIND THOUSANDS OF COMPLAINTS REGARDING THE SAME ISSUE IN TOYOTAS & LEXUS VEHICLES SINCE AT LEAST 2001. THE DEALERSHIPS LOOK AT ME LIKE I AM THE VERY FIRST &...
