2008 Toyota Prius traction control system problems

“I HAVE REPORTED THIS ISSUE TO THIS WEBSITE IN THE PAST. THE TRACTION CONTROL DISABLES THE DRIVE WHEELS INCONSISTENTLY AND ARBITRARILY UNDER MANY CIRCUMSTANCES, OFTEN RESULTING IN A REAL SAFETY HAZARD. IT CAN HAPPEN WHEN STARTING FROM A STOP ON DRY OR WET PAVEMENT OR WHEN HITTING SMALL BUMPS/HOLES AT LOW SPEEDS (25-45 MPH). THIS IS EXTREMELY FRIGHTENING WHEN TRYING TO PULL INTO TRAFFIC FROM A STOP ON DRY PAVEMENT - POWER IS CUT, SLOWING ENTRY INTO MOVING TRAFFIC AND INCREASING ACCIDENT POTENTIAL. THE LOCAL TOYOTA DEALER TELLS US THAT NOTHING CAN BE DONE ABOUT IT. SURELY IT'S A SERIOUS ENOUGH HAZARD THAT NEEDS TO BE ADDRESSED. *TR”

“WHEN I BRAKE AND ALSO GO OVER A BUMP MY 2008 PRIUS LURCHES FORWARD. THE TRACTION CONTROL LIGHT ILLUMINATES. THE BRAKES BECOME INEFFECTIVE. THIS CAUSED ME TO HAVE AN ACCIDENT LAST NIGHT. THE CARS BEFORE ME CAME TO A SUDDEN STOP. I WAS DRIVING 15-20MPH BUT UNFORTUNATELY I HIT THE BRAKES WHILE UNKNOWNINGLY SIMULTANEOUSLY GOING OVER A BUMP. THE FAULTY TRACTION CONTROL SYSTEM SENT ME INTO A 1-2 SECOND LURCH FORWARD WITH ZERO BRAKES. WHEN I FINALLY WAS ABLE TO HAVE BRAKES I HAD TO MANEUVER THE VEHICLE TO THE LEFT OF THE CAR AHEAD SCRATCHING THE AURA AND DENTING MY FRONT RIGHT PANEL. THIS IS NOT THE FIRST TIME THE BRAKES HAVE FAILED BUT IT IS THE FIRST TIME I WAS INVOLVED IN AN ACCIDENT BECAUSE OF IT. TOYOTA DRIVERS NEED TO LEAVE A 4 SEC. SPACE BETWEEN CARS TO MAKE UP FOR THE 2 SEC. LAPSE IN BRAKES. *TR”

“TL* THE CONTACT OWNS A 2008 TOYOTA PRIUS. WHILE ATTEMPTING TO ACCELERATE, THE CONTACT NOTICED THAT THE VEHICLE WOULD PAUSE AND THE TIRES LOST TRACTION. THE VEHICLE WAS TAKEN TO THE DEALER WHO STATED THE VEHICLE WAS PERFORMING NORMALLY AND COULD NOT BE REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE 25,000.”

“I OWN A 2008 TOYOTA PRIUS AND HAVE EXPERIENCED BRAKING PROBLEMS SINCE I PURCHASED THE VEHICLE. ANY TIME I GO OVER A BUMP/POTHOLE, WHILE TURNING, RESULTS IN A FLOATING SENSATION, SURGE FORWARD, AND MOMENTARY LOSS OF STEERING. I ALMOST HAD AN ACCIDENT 2 WEEKS AGO AT AN INTERSECTION WHEN THIS OCCURRED. SERVICED MY VEHICLE YESTERDAY AND THEY CLAIM THE SKID CONTROL SYSTEM IS WORKING AS IT WAS DESIGNED. THERE IS DEFINITELY A FATAL FLAW IN THIS SYSTEM AND LIKELY A CHIP ISSUE. TOYOTA IS NOT DOING ANYTHING. *TR”

“2008 TOYOTA PRIUS. CONSUMER STATES PROBLEM WITH TRACTION CONTROL *TGW THE CONSUMER STATED SHE WAS DRIVING IN THE RAIN AT A SPEED OF 40 MPH WHEN SHE NOTICED THE TRACTION CONTROL LIGHT WAS FLICKERING ON AND OFF MORE THAN SHE PREVIOUSLY EXPERIENCED. SHE ALSO SMELLED AN ODOR SIMILAR TO SOMETHING BURNING. SHE OPENED THE WINDOWS TO LET IT CLEAR. HOWEVER, THE SMELL SEEMED TO LINGER IN THE VEHICLE FOR AT LEAST A MILE. AS SHE APPROACHED A TOWN, THE SPEED LIMIT WAS REDUCED FROM 45 MPH TO 25 MPH SO SHE SLOWED DOWN AND CONTINUED TO EXPERIENCE THE FLICKERING OF THE TRACTION CONTROL WARNING LIGHT WHILE DRIVING ON WET PAVEMENT. AS THE CONSUMER APPROACHED A CONTROLLED INTERSECTION AT A SPEED OF APPROXIMATELY 20 MPH AND WAS APPLYING THE BRAKES TO STOP FOR THE RED LIGHT, THE VEHICLE SUDDENLY SHUT DOWN AS SHE WAS UNABLE TO STEER AND HAD NO BRAKES OR TRACTION. AS SHE WAS ABOUT TO HIT THE VEHICLE IN FRONT OF HER, SHE SLAMMED ON THE BRAKES ONE LAST TIME AND WAS ABLE TO STOP AT THE LAST SECOND. WHEN THE LIGHT TURNED GREEN SHE PROCEEDED TO DRIVE IN THE RAIN AT A MAXIMUM SPEED OF 40 MPH AND THE TRACTION CONTROL WARNING LIGHT CAME ON ONLY ONE ADDITIONAL TIME UNTIL SHE REACHED HER…”

“I DRIVE A 2008 PRIUS. WHEN BRAKING AND DRIVING OVER A POT-HOLE, BUMP, OR OTHER ROAD WORK THE ANTI-LOCK BRAKING SYSTEM ENGAGES, AND THE BRAKES RELEASE FOR AN EXTENDED PERIOD OF TIME (>1 SECOND) CAUSING THE CAR TO COAST DURING THIS TIME. I DRIVE ON BUSY CITY STREETS AND ON HIGHWAYS WITH STOP AND GO TRAFFIC, AND THIS UNCONTROLLED BRAKE RELEASE REPRESENTS A SAFETY HAZARD. I HAVE DRIVEN VEHICLES WITH ANTI-LOCK BRAKES BEFORE, AND THIS KIND OF BRAKING RELEASE IS MUCH LONGER AND RESULTS IN A MUCH GREATER LOSS OF VEHICLE CONTROL THAN IN OTHER VEHICLES I HAVE DRIVEN. IN A SPECIFIC RECENT INCIDENT, I HIT A CAR IMMEDIATELY IN FRONT OF ME. IN THE INCIDENT, I WAS DRIVING OVER BUMPY PAVEMENT AND THE CAR IN FRONT OF ME STOPPED ABRUPTLY. AS I TRIED TO BRAKE SHARPLY TO AVOID HITTING THE CAR IN FRONT, THE BRAKING RELEASED BECAUSE THE ANTI LOCK BRAKES ENGAGED, AND INSTEAD OF STOPPING SAFELY, I HIT THE CAR. ALTHOUGH THERE WERE NO INJURIES AND DAMAGE WAS MINOR, THE INCIDENT (AND THE REGULARITY WITH WHICH THE BRAKES RELEASE UNDER NORMAL DRIVING CONDITIONS) SEEMS TO ME TO REPRESENT A SIGNIFICANT SAFETY PROBLEM FOR THE VEHICLE. *TR”
