2006 Toyota Sienna wheels problems

“The TPMS system failed in the ECM or engine computer. It uses the wheel speed sensors on each hub to measure differences in wheel speed and uses this to infer if any one wheel has low tire pressure. (This vehicle does not have TPMS sensors in the wheels.) However, with this failure, it reports a tire pressure problem even though all 4 tires are inflated properly. This problem persists even after cleaning then replacing wheel speed sensors. The problem appears to be in the ECM or engine computer, which is very difficult and expensive to replace. With this problem, the driver is never able to tell if any tire actually has low pressure because the system always reports that a tire has low pressure. Toyota should be required to fix this issue in all affected vehicles.”

“TL* THE CONTACT OWNS A 2006 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE GOING AROUND A CURVE, THE VEHICLE INDEPENDENTLY SLOWED ABRUPTLY WITHOUT THE BRAKE PEDAL BEING DEPRESSED. THE TRACTION CONTROL WARNING LIGHT WAS ILLUMINATED. THE DEALER COLONIAL TOYOTA (2600 W PIKE RD, INDIANA, PA 15701, (724) 471-4287) SUGGESTED THAT THE ISSUE MAY BE DUE TO A BROKEN WIRE OR A DIRTY SENSOR. IT WAS SUGGESTED THAT THE VEHICLE NEEDED TO BE DIAGNOSED. THE CONTACT TOOK THE VEHICLE TO AN INDEPENDENT MECHANIC AND WAS INFORMED THAT THE FRONT AND REAR WHEEL HUBS NEEDED TO BE REPLACED. THE REPAIRS WERE COMPLETED HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE SAME INDEPENDENT MECHANIC REPLACED AND THE SPEED SENSORS WERE REPLACED HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE CONTACT WAS INFORMED THAT THE VEHICLE WAS NOT COVERED UNDER WARRANTY OR RECALL. THE FAILURE MILEAGE WAS UNKNOWN.”

“THE SLIP INDICATOR LIGHT (CAR WITH SWERVE LINES) STARTED COMING ON INTERMITTENTLY WHILE TURNING ON HIGHWAYS ETC. (BUT NOT WHEN ANY RISK OF TIRE SLIPPING). THEN VSC LIGHT ALSO CAME ON AND ALARM SOMETIMES SOUNDED. VISIT TO OUR OWN MECHANIC, NO PROBLEMS FOUND. IN THE LAST 2 YEARS THE ABS SYSTEM HAS ACTIVATED (DAILY) IT UNEXPECTEDLY APPLIES THE BRAKES WHILE IN MOTION. IT IS ON SPECIFIC TYPES OF CURVE AND WHILE DRIVING AT LEAST 30MPH, BUT HAS DONE AT 35, 55, 70 MPH, ON SLIGHT OR MEDIUM TURNS (NOT REAL SHARP TURNS), GOING UPHILL OR DOWNHILL AND LEFT OR RIGHT. TOOK MY MECHANIC FOR A RIDE WITH THE DIAGNOSTIC COMPUTER HOOKED UP, IT DID THE ABS BRAKING, WARNING LIGHT, AND BEEPING 5 TIMES BUT COMPUTER SHOWED NO CODES. SUGGESTED RESETTING YAW WHICH WE DID, IT DID NOT HELP. SUGGESTED CALLING TOYOTA, THEY WERE NO HELP, SAID THEY HAD NEVER HEARD OF THAT PROBLEM AND MY MECHANIC PROBABLY DID NOT KNOW HOW TO READ THE COMPUTER. WHEN ABS ACTIVATES IT'S VERY DANGEROUS - THINKING ABOUT DEACTIVATING ENTIRE VSC SYSTEM. I BELIEVE THE RACK AND PINION MAY PLAY A ROLE, THERE ARE RATTLE AND BUMP SOUNDS, PERHAPS A LOOSE SUSPENSION IS THE CULPRIT, THAT IS OUR NEXT OPTION. I HAVE ALREADY…”

“CHECK ENGINE LIGHT, VSC LIGHT, TRACTION CONTROL LIGHT. ALL 3 LIGHTS CAME ON AT SAME TIME. THEY SAY IT'S THE GAS CAP, IT'S NOT THE GAS CAP, THEY SAY TO RESET IT, THAT DOESN'T WORK. I WAS DRIVING HOME, NOTHING HAPPENED, THE LIGHTS JUST CAME ON. NO WARNING SOUND, NOTHING TO INDICATE THERE WAS A PROBLEM, MY CAR SEEMS TO DRIVE JUST FINE, BUT THE LIGHTS WON'T GO OFF, AND I HAVE 3 KIDS THAT I TAKE AND PICK UP FROM SCHOOL”
