Open the full vehicle complaint log (all categories)IN COLD TEMPERATURES THE BRAKE PEDAL FREEZES AND YOU CAN NOT PUSH THE PEDAL. THE CAR DOES NOT RESPOND. SEEMS TO ACT IN EXACTLY THE SAME WAY THAT THE RECALL FOR THE 2008-09 MODELS! *TR
TL* THE CONTACT OWNS A 2006 TOYOTA SCION XB. THE CONTACT STATED THAT WHILE ATTEMPTING TO PARK THE VEHICLE, THE BRAKE PEDAL BECAME DETACHED FROM ITS ASSEMBLY. AS A RESULT, THE CONTACT ERRONEOUSLY ENGAGED THE ACCELERATOR PEDAL INSTEAD OF THE BRAKE PEDAL AND CRASHED INTO A TREE. A POLICE REPORT WAS NOT FILED AND NO INJURIES WERE REPORTED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE HOWEVER, PROCEEDED TO REINSTALL THE PEDAL. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND SENT AN ENGINEER TO INSPECT THE VEHICLE. THE ENGINEER ADVISED THAT THE VEHICLE WAS PERFORMING UP TO STANDARDS AND DID NOT PROVIDE ANY ADDITIONAL ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 124,791 AND THE CURRENT MILEAGE WAS 145,000.
TODAY, 3/19/10 AT AROUND 9:30 A.M. I WAS DRIVING MY 2006 TOYOTA SCION HOME FROM THE DENTISTS OFFICE. NEARING THE TOP OF A HILL MY THROTTLE STUCK IN THE FULL POSITION AND THE BRAKE PEDAL FAILED TO DEPRESS. I PUT THE TRANSMISSION IN NEUTRAL, THE ENGINE REVVED AT HIGH SPEED, I RETURNED THE TRANSMISSION TO DRIVE AND THE PROBLEM PERSISTED. I REPEATED THE GEAR CHANGE AND THE SECOND TIME THE ENGINE AND TRANSMISSION RESPOND PROPERLY. I CALLED MY LOCAL TOYOTA DEALER WHO OFFERED NO HELP UNLESS I CAN REPEAT THE PROBLEM. P.S. I AM (AND HAVE BEEN) A STATE LICENSED VEHICLE SAFETY & EMISSIONS INSPECTOR (MA)BY PROFESSION. PRIOR TO THIS I WAS A STATE LICENSED MECHANIC & VEHICLE EMISSIONS INSPECTOR (CA). *TR
ACCELERATED (TOOK OFF) WHILE DRIVING AT HIGHWAY SPEED (5 INCIDENCES)...ORIGINALLY I THOUGHT IT WAS A PROBLEM WITH MY AFTERMARKET CRUISE CONTROL. I CALLED DEALERSHIP AND REPORTED THAT THEY SHOULD NOT RECOMMEND AFTERMARKET CRUISE AT THE TIME...THEY CLAIMED NO OTHER PROBLEMS. AFTER 2ND INCIDENCE CRUISE CONTROL WAS REPLACED BY INSTALLER AND HE CALLED THE COMPANY...NONE WAS FAMILIAR WITH THE PROBLEM ON MY CRUISE MODULE (HE SHOWED ME HOW TO DISCONNECT CRUISE UNDER THE HOOD SINCE CURRENT STILL RUNS THROUGH MECHANISM SINCE CRUISE WAS IN OFF POSITION DURING 2ND INCIDENT)...THE PROBLEM THEN HAPPENED AGAIN (3 TIMES IN SAME DAY ON WAY TO AIRPORT)WITH NEW CRUISE MECHANISM. NO PROBLEMS IN LAST 2 YEARS, BUT IT'S A DAILY GAMBLE...NOW I HAVE TO WONDER IF THE CRUISE WAS EVER EVEN PART OF THE EQUATION IN THE PROBLEM WITH ALL THE ACCELERATOR AND OTHER PROBLEMS I'VE READ ONLINE. I CHECKED WITH THE DEALERSHIP AGAIN THIS YEAR AND THEY DENY ANY PROBLEM WITH SCION ACCELERATORS OR BRAKE NOT DEPRESSING (IT ALWAYS FELT LIKE MY BRAKE AND GAS WERE FIGHTING LIKE IF YOU 2 FOOTED IN A MANUAL EQUALLY, BUT I OWN A AUTOMATIC...IT'S VERY SCARY). *TR
