2004 TOYOTA SIENNA Complaints

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 60 MPH, THE POWER STEERING ASSIST FAILED WITHOUT WARNING. THE STEERING WHEEL BECAME HARD TO TURN. THE CONTACT ALSO STATED THAT BOTH PASSENGER SIDE WINDOWS WERE INOPERABLE. THE VEHICLE WAS TAKEN TO INDEPENDENT MECHANIC, WHO WAS UNABLE TO DIAGNOSE THE VEHICLE. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS NOT AWARE OF THE PROBLEMS. THE APPROXIMATE FAILURE MILEAGE WAS 115,000.

COMPLETE LOSS OF POWER WHILE IN MOTION ENTERING FREEWAY. PREVIOUSLY HAD NOTICED STEERING DIFFICULTY AT TIMES AND ENGINE LIGHT GOING ON, BUT HAD ALWAYS STOPPED AFTER A SHORT WHILE. AFTER THE FAILURE IT WAS DIAGNOSED AS FAILURE OF CRANK SHAFT PULLEY. WE FOUND THAT TOYOTA HAD DONE A RECALL FOR THIS ISSUE, BUT HAD NOT INCLUDED OUR VEHICLE IN THE RECALL OR NOTIFIED US. TOYOTA DENIED COVERAGE OF THE REQUIRED REPAIR. DRIVER AND TWO SMALL CHILDREN IN CARE AT TIME OF FAILURE, JUST ABOUT TO ENTER FREEWAY. OVER $800 IN REPAIRS. *TR

VEHICLE RANDOMLY SELF-LOCKS WHILE IN PARK WITH CAR TURNED OFF, WITHOUT ANY INDICATION. THIS HAS HAPPENED WITH MY KEYS INSIDE THE VEHICLE ON THE SEAT WHILE PUTTING GROCERIES IN THE BACK AT THE STORE AND AT HOME. IT HAPPENS ALL THE TIME NOW, AND ITS SCARY, BECAUSE I HAVE A YOUNG CHILD WHO I STRAP INTO THE CAR SEAT AND THEN WALK AROUND TO THE DRIVERS SIDE, USUALLY AFTER PUTTING MY PURSE AND KEYS DOWN ON SEAT UP FRONT. IF CAR SELF LOCKS, KIDS COULD BE TRAPPED INSIDE. RESEARCH ON LINE SHOWS THIS IS A PROBLEM WITH OTHER TOYOTAS, POSSIBLY HAVING SOMETHING TO DO WITH A SECURITY SYSTEM HARNESS GLITCH OR DOOR LOCK ACTUATOR? *TR

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT THAT THE VEHICLE WAS SERVICED UNDER NHTSA CAMPAIGN NUMBER 13V429000 (POWER TRAIN) HOWEVER, THE CONTACT WAS UNABLE TO SHIFT INTO PARK AFTER THE RECALL SERVICE. THE VEHICLE WAS NOT DIAGNOSED OR FURTHER REPAIRED. THE MANUFACTURER WAS CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE AND VIN WAS NOT AVAILABLE.

RIGHT PASSENGER HEADLIGHT HAS SOME SORT OF WATER LEAKING INTO THE HEADLIGHT. A SUBSTANTIAL AMOUNT OF MOISTURE ACCUMULATES AND CAN CAUSE ELECTRICAL ISSUES. *TR

SUMMARY: SENSOR IN STABILITY CONTROL FAILED AND FALSELY REPORTED CRISIS SITUATION, CAUSING COMPUTER TO SEIZE CONTROL TO SLOW VEHICLE AND CHANGE COURSE. LONG VERSION: WHILE DRIVING STRAIGHT ON CITY STREET, SUDDENLY VEHICLE SLOWED AND PULLED TO SIDE, STABILITY CONTROL LIGHT AND AUDIO ALARM ACTIVATED, HEARD GRINDING NOISE THAT SOUNDED LIKE ABS. CONDITION PERSISTED IF DRIVING OVER 5-10 MPH. CRAWLED TO NEARBY NON-DEALER REPAIR SHOP. DIAGNOSIS/SOLUTION: STEERING ANGLE SENSOR REPORTING WHEELS AT 250 DEGREES WHEN ACTUALLY STRAIGHT AHEAD, WOULD NOT RECALIBRATE, CIRCUIT INTEGRITY OTHERWISE GOOD, SENSOR WAS REPLACED. NO RESIDUAL PROBLEMS NOTED SO FAR SINCE THEN (ONE DAY). I HAVE THE FAILED SENSOR. THIS SENSOR PROBLEM WAS CAUSE OF A PRODUCTION CHANGE AND TSB BR008-04 IN THE FIRST YEAR. OBVIOUSLY TOYOTA HAS KNOWN ABOUT THIS PROBLEM FOR YEARS, BUT NO RECALL. OTHER ACCOUNTS EXIST ON LINE OF PEOPLE WHO HAVE HAD THIS HAPPEN. THIS IS A MAJOR SAFETY HAZARD. IT'S THE MECHANICAL EQUIVALENT OF RIDING WITH A DRIVER ON LSD WHO IS BRAKING/SWERVING TO AVOID HALLUCINATIONS. I WAS LUCKY TO BE GOING SLOWLY ON AN UNCROWDED STREET, BUT AT HIGHER SPEED OR CROWDED CONDITIONS THIS COULD BE A DISASTER. TOYOTA HAS NOT BEEN TERRIBLY HELPFUL SO FAR, BUT DISCUSSION WILL CONTINUE.... *TR

REAR SLIDING DOOR ISSUE - THE TRUNK KEEPS FALLING ON THE HEAD WHEN PUTTING SHOPPING BAGS. POWER SLIDING DOOR ASSEMBLY - THE SLIDING DOOR KEEPS CLOSING AND INJURING WHEN PUTTING THE SEAT BELTS FOR MY BABY IN THE CAR SEAT. THESE ARE SAFETY ISSUES AND CAUSING INJURY. *TR

THE FRONT SEAT BELTS ON BOTH THE DRIVER'S SIDE AND THE PASSENGER'S SIDE WILL NOT RETRACT. ONCE EXTENDED, THEY GET STUCK IN THE EXTENDED POSITION, MAKING THE SEAT BELT RESTRAIN SYSTEM COMPLETELY INOPERABLE. THE SEAT BELT WILL CLICK INTO THE LOCK MECHANISM, BUT THE BELT IS COMPLETELY LOOSE, AND THE RETRACT/LOCK SYSTEM DOES NOT WORK. THIS IS AN UNSAFE CONDITION. I RESEARCHED ONLINE TO TRY TO FIX THIS PROBLEM MYSELF, AND I FOUND HUNDREDS OF OTHER COMPLAINTS EXACTLY LIKE THIS ONE, EACH WITH VARYING MILEAGE ON THEIR 2004-2010 MODEL YEAR SIENNAS. ITS ONE OF THE MOST POPULAR SELLING MINIVANS, DON'T YOU THINK TOYOTA SHOULD FIX THIS SAFETY ISSUE?? *TR

STEERING SHAFT INTERMEDIATE SHAFT STEERING & SUSPENSION POWER STEERING NOT WORKING ALL THE TIME. SEEMS TO GET TIGHTER AND TIGHTER FROM TIME TO TIME. VERY DIFFICULT MAKING LEFT OR RIGHT TURN... *TR

IN JUST NORMAL USE, WITHOUT EVER HAVING BEEN INVOLVED IN A COLLISION CAUSING THE SEATBELT TO RESTRAIN A PASSENGER, THE SEAT BELT ON THE FRONT PASSENGER SIDE OVER EXTENDS AND FOLDS. THE BELT WILL NOT RETRACT AND CAUSES THE PASSENGER SEAT TO BE UNUSABLE. THE FOLD IS NEARLY IMPOSSIBLE TO REMOVE AND THE BELT REMAINS EXTENDED. THIS HAS HAPPENED NUMEROUS TIMES OVER THE COURSE OF OWNING THE VEHICLE, TO MANY DIFFERENT PASSENGERS. *TR
