Open the full vehicle complaint log (all categories)TL* THE CONTACT OWNED A 2011 SCION XB. WHILE DRIVING 35 MPH, THE VEHICLE FAILED TO STOP WHEN THE BRAKE PEDAL WAS DEPRESSED. AS A RESULT, THE CONTACT REAR ENDED ANOTHER VEHICLE. THE AIR BAGS DEPLOYED. THE CONTACT SUFFERED A MINOR EAR INJURY THAT DID NOT REQUIRE MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED AND DEEMED TOTALED BY THE CONTACT'S INSURANCE COMPANY. THE CONTACT CALLED AN AUTO FINANCE COMPANY, BUT THEY DID NOT ASSIST. THE DEALER AND MANUFACTURER WERE NOT NOTIFIED. THE FAILURE MILEAGE WAS 153,000. THE VIN WAS UNKNOWN.
WHILE TRAVELING IN A STRAIGHT LINE OF LEFT LANE ON THE PARKWAY AT 50 MPH, I LIGHTLY APPLIED THE BRAKES AND THE REAR OF THE VEHICLE IMMEDIATELY BEGAN TO SWAY UNCONTROLLABLY LEFT AND RIGHT. THE BRAKES WERE LOCKED CAUSING THE VEHICLE TO HEAD OFF THE ROAD AND ONTO THE GRASS AND CRASH INTO THE GUIDE RAIL. IMMEDIATELY FOLLOWING THE ACCIDENT, I NOTICED THE ABS+VSC+EMERGENCY BRAKE LIGHTS WERE LIT. I HAD THE CAR TOWED TO THE COLLISION SHOP FOR INSPECTION AND REPAIRS WHICH WILL HOPEFULLY START NEXT WEEK. I ASKED THAT THE COMPUTER CODE READOUTS BE NOTED BY THE INSPECTOR WHEN HE ARRIVES. I'VE BEEN DRIVING THIS ROUTE TO WORK FOR 55,000 MILES AND NEVER EXPERIENCED THIS TYPE OF RESPONSE DURING BRAKING. THE VEHICLE HAS A CURRENT INSPECTION STICKER ON IT. *TR
