2011 Toyota 4runner Brakes Problems

Your 4Runner's ABS braking system has failed, and you're experiencing reduced braking power to the rear wheels. The dealer identified a discontinued part—possibly the proportioning valve or a related component—as the cause, with repair costs around $2,000 plus labor. This is a serious safety issue that should be addressed immediately before driving the vehicle.

TL* THE CONTACT OWNS A 2011 TOYOTA 4RUNNER. WHILE DRIVING APPROXIMATELY 35 MPH, THE BRAKES LOCKED AND THE CONTACT LOST CONTROL OF THE VEHICLE. THE FAILURE OCCURRED NUMEROUS TIMES AND AT DIFFERENT SPEEDS. THE VEHICLE WAS TAKEN TO A DEALER, BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 4,500.

CERTIFIED LETTER (7013 1090 0001 3828 4870)- LETTER FROM CONSTITUENT REGARDING ISSUES WITH HIS TOYOTA RUNNER. *SMD 2011 TOYOTA 4RUNNER. THE CONSUMER STATED HE PURCHASED THE VEHICLE IN NOVEMBER 2010. THREE MONTHS LATER HE HAD AN ACCIDENT, DUE TO THE BRAKES NOT RESPONDING. ONE MONTH AFTER THE ACCIDENT, HE WAS INVOLVED IN ANOTHER ACCIDENT, DUE TO THE BRAKES NOT RESPONDING AGAIN. THE CONSUMER TOOK THE VEHICLE BACK TO THE DEALER, TO HAVE THEM INSPECT THE BRAKES, BUT THEY DIDN'T FIND ANYTHING WRONG.

TL* THE CONTACT OWNS A 2011 TOYOTA 4RUNNER. THE CONTACT STATED THAT WHILE DECELERATING FROM 60 MPH, THE BRAKES FAILED TO ENGAGE. THE CONTACT CONTINUED TO DEPRESS THE BRAKES WITH FORCE UNTIL THE ANTILOCK BRAKING SYSTEM ENGAGED. THE VEHICLE CONTINUED TO MOVE AND THE CONTACT WAS ABLE TO TURN THE VEHICLE TO THE RIGHT AND MOVED AWAY FROM ONCOMING TRAFFIC. THE FAILURE WAS EXPERIENCED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO THE DEALER AND A DIAGNOSTIC WAS PERFORMED, WHICH WAS UNABLE TO LOCATE A FAILURE CODE. THE VEHICLE WAS ALSO TEST DRIVEN AND THE FAILURE WAS NOT DUPLICATED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 15,047 AND THE CURRENT MILEAGE WAS 23,203.

BRAKES APPLIED AT 45 MPH,VSC ACTIVATED,REAR BRAKES LOCKED ON AND WOULD NOT RELEASE. VEHICLE WAS DRIVEN TO A SAFE LOCATION OFF THE HIGHWAY AND WAS TRANSPORTED TO OWNERS HOME VIA FLATBED. THE REAR BRAKES WERE VERY HOT AND GRABBING AS I EXITED THE HIGHWAY. THE PARKING BRAKE LIGHT IN THE CONSOLE LIT. AND THE AUDIO BEEPER SOUNDED CONTINUOUSLY. INCIDENT WAS REPORTED TO THE TOYOTA DEALER. THEY DID NOT REQUEST TO INSPECT THE VEHICLE. *TR

PURCHASED VEHICLE NEW AND THE 5 SPEED AUTOMATIC TRANSMISSION OPERATED SMOOTHLY. AROUND 9,300 MILES THE TRANSMISSION STARTED SHIFTING GEARS HARSHLY. THE HARSHNESS IS INTERMITTENT BUT HAPPENING MORE FREQUENTLY. ALSO, WHILE AT HIGHWAY SPEEDS GOING DOWNHILL, THE RPMS BOUNCE EVERYWHERE FROM 1500 RPMS TO 3000 RPMS. ITS ALMOST AS IF THE TRANSMISSION IS CONFUSED AND DOESN'T KNOW WHAT GEAR TO CHOOSE ANYMORE. I ALSO FEEL AS IF THE BRAKES AREN'T RELEASING. WHEN SITTING AT A RED LIGHT GOING DOWN HILL, ONCE I RELEASE MY FOOT OFF THE BRAKE AND BEFORE I ACCELERATE, WHILE COASTING, I FEEL A "THUD" IN THE REAR END AFTER ABOUT TWO ROTATIONS OF THE WHEELS. I DRIVE IN BUMPER-TO-BUMPER TRAFFIC DAILY IN PITTSBURGH AND THIS SHIFTING IS AWFUL - BY FAR THE WORST TRANSMISSION IN A VEHICLE I HAVE EVER OWNED. I MENTIONED THIS ISSUE DURING MY LAST SERVICE VISIT AT THE TOYOTA DEALERSHIP AND THEY SAID A TECHNICAL SERVICE BULLETIN HAD NOT BEEN ISSUED YET. THIS NEEDS ADDRESSED ASAP. THIS CAN'T BE THE WAY TOYOTA INTENDED FOR THIS VEHICLE TO OPERATE - ESPECIALLY SINCE IT DIDN'T ALWAYS OPERATE THIS WAY. *TR
