2004 TOYOTA SIENNA Complaints

AFTER CHANGING THE FRONT BRAKE PADS ON OUR 2004 TOYOTA SIENNA SOMETIME EARLY 2009 AND WHILE IT WAS PROPPED UP ON METAL RAMP, MY DAUGHTER PLACED THE TRANSMISSION IN REVERSE APPLIED SOME GAS, IT INSTANTLY TOOK OFF AT A HIGH SPEED IN REVERSE. THE CAR TRAVELED APPROX 40 FEET BACKING INTO A DITCH WHICH AT THAT TIME IT STOPPED POSSIBLY BECAUSE OF THE SUDDEN ABRUPT DITCH. I HER FATHER WAS WATCHING AND ASKED "WHAT DID YOU DO" SHE STATED "NOTHING IT JUST TOOK OFF" THIS WAS A YEAR BEFORE I HEARD OF THE TOYOTA PROBLEMS SO I JUST SHRUGGED IT OFF AS A WEIRD INCIDENT. NOW HEARING OTHER INCIDENCES I SUDDENLY REMEMBERED MY INCIDENT. I ONLY REPORT IT NOW BECAUSE IT MAY HELP WITH ANY INVESTIGATION AS TO WHAT THE PROBLEM IS. I HAVE NOT YET HEARD OF THE ACCELERATING PROBLEM HAPPENING IN REVERSE LIKE IT HAPPENED TO ME. *TR

2004 CERTIFIED USED TOYOTA SIENNA HAS A DRIVER'S DOOR CHECK ISSUE IN WHICH EITHER THE WELD BREAKS OR IN MORE SEVERE SITUATIONS, THE WELD ACTUALLY PULLS OFF THE DOOR REQUIRING COMPLETE REPLACEMENT OF THE DOOR TO FIX IT. THE SOLUTION WAS TO ISSUE A SERVICE BULLETIN EXTENDING THE WARRANTY TO 5 YRS, 100,000 MI. MY CAR WAS PURCHASED THE DAY AFTER THE 5 YRS WAS UP AND IS WELL WITHIN THE 100,000 MI. WHEN ADDRESSED A FEW MONTHS AFTER PURCHASE AS THE SOUND BECAME NOTICEABLE ENOUGH TO TAKE IT IN FOR CHECKING OUT, THE WELDED BRACKET WAS TEARING A HOLE IN THE BODY OF THE CAR NOT JUST A BROKEN WELD. THE DEALER REFUSES TO TAKE CARE OF IT ONLY AGREEING TO PAY 1/2 THE REPLACEMENT COST OF $1800. I UNDERSTAND THIS IS A DANGER BECAUSE IF IT FAILS COMPLETELY, THIS DOOR CAN BOTH COME OFF THE FRAME AS WELL AS SWING UNCONTROLLED AND SLAM BODY PARTS IN THE DOOR. *TR

SUDDEN UNEXPLAINED ACCELERATION AND BRAKE FAILURE ON MY 2004 TOYOTA SIENNA. I WAS ALMOST AT A STOP AT A TRAFFIC LIGHT WHEN THE LIGHT TURNED GREEN. I PRESSED THE ACCELERATOR. MY VAN SHOT OFF! IT ACCELERATED VERY RAPIDLY. I PRESSED THE BRAKE. THEY DID NOT ENGAGE. I PRESSED THE BRAKE AGAIN. THEY WENT TO FLOOR. WITH ONCOMING TRAFFIC ON MY LEFT AND A CAR IN THE RIGHT LANE, I HAD NOWHERE TO GO. I HIT THE TRUCK IN FRONT OF ME WHO WAS STOPPING AT THE NEXT TRAFFIC LIGHT. HAD I BEEN ON A CURVY ROAD OR THE INTERSTATE, I COULD HAVE BEEN SERIOUSLY INJURED. I DID NOT LOOK AT THE SPEEDOMETER TO SEE HOW FAST THE VAN GOT. I WAS TOO BUSY TRYING TO FIND A WAY NOT TO HIT SOMEONE. THIS WAS VERY SCARY. UPDATED 04/22/10 *BF UPDATED 05/10/10 *BF UPDATED IVOQ 05/12/10 UPDATED 09/28/10

AUTOMATIC SLIDING PASSENGER DOOR CABLE SNAPPED AND IT DOESN'T WORK EVEN MANUALLY. *TR

3-5-10 AT ABOUT 11:39AM I WAS MAKING A LEFT TURN INTO A PARKING SPACE IN FRONT OF MY CONDOMINIUM WHEN MY 2004 TOYOTA SIENNA SUDDENLY LURCHED FORWARD AND JUMPED THE PARKING STOP AND HIT A CEMENT WALL. I TRIED TO BRAKE THE CAR AND THEY DID NOT WORK. I HAD NEW BRAKE PADS ON 3-1-10 AND MY CAR SERVICED. THE CAR WAS TOWED TO BEACHSIDE AUTO BODY REPAIR, INDIAN HARBOUR BEACH, FL 32937. FRONT END DAMAGE. WE ASKED THAT THEY HAVE A MECHANIC INSPECT THE CAR. *TR

I DRIVE A 2004 TOYOTA SIENNA XLE. ON 3/4/10 AT 1030 AM, I WAS COMING TO A STOP LIGHT ON BROKEN LAND PKWY. AS I COMPLETED A FULL STOP, MY SIENNA TRIED TO ACCELERATE WHILE MY FOOT WAS DEPRESSING THE BRAKE PEDAL. THE VEHICLE LURCHED BUT DID NOT STALL OUT AND I WAS ABLE TO CONTINUE ON MY WAY. DURING THE REST OF THE MORNING, I DID NOT EXPERIENCE ANY MORE ACCELERATION TROUBLE THE REST OF THE DAY. I DID INFORM MY HUSBAND AND HE SUGGESTED I RESEARCH 2004 TOYOTA SIENNA ACCELERATION. I DID THAT AND FOUND A VARIETY OF COMPLAINTS FROM 2004 TOYOTA SIENNA OWNERS ON SEVERAL INTERNET AUTO WEB SITES. *TR

TOYOTA 2004 SIENNA. IT'S THE MOST DANGEROUS CAR I EVER HAD, WHENEVER I SLOW DOWN AND TEND TO ACCELERATE, THE CAR HESITATE TO GO FOR ABOUT 1 TO 3 SECONDS DELAY. I TOOK IT TWICE TO THE DEALER BUT DID NOT FIX THE PROBLEM, THE THIRD TIME I WENT BACK THEY DENIED THAT IT IS A PROBLEM. IT IS DANGEROUS SPECIALLY WHEN YOU TEND TO PASS A CAR ON A TWO WAY ROAD AND THE CAR WONT ACCELERATE AT DESIRED TIMING. MY COMPLAIN WAS TOYOTA DENIES THAT THERE IS A PROBLEM. THIS PROBLEM IS AN ONGOING SINCE I PURCHASED IT IN 2004 TO PRESENT. *TR

TOYOTA 2004 SIENNA - POWER SLIDING DOOR FAILURES. DRIVER SIDE SLIDING DOOR FAILED TO OPEN AS CABLE SNAPPED. DOOR WAS JAMMED SHUT SO WE TOOK THE CAR TO THE DEALERSHIP AND WERE TOLD WE WOULD HAVE TO REPLACE THE WHOLE MOTOR UNIT AT A COST OF $1,700. SERVICE DEPT DISCONNECTED MOTOR UNIT SO THAT DOOR WOULD OPEN AND CLOSE (BUT WITH NO POWER OPTION). TWO DAYS LATER THE CABLE SNAPPED ON THE PASSENGER SIDE SLIDING DOOR WITH THE DOOR OPEN. IT WOULD NOT CLOSE. RETURNED TO THE DEALERSHIP AND SAME ACTION WAS TAKEN AS DRIVER SIDE DOOR. WILL NOW COST $3,400 TO FIX. WITH 3 CHILDREN THE SAFETY ASPECT OF A DOOR CABLE SNAPPING WITH EITHER THE DOOR JAMMED OPEN OR CLOSED IS OBVIOUSLY A MAJOR CONCERN. HAVING RESEARCHED THIS ISSUE OVER THE PAST FEW DAYS I CAN SEE THAT MANY SIENNA OWNERS HAVE HAD THE SAME PROBLEM. THIS IS A MAJOR SAFETY AND COST ISSUE THAT SHOULD BE INVESTIGATED. *TR

TL*THE CONTACT OWNS A 2004 TOYOTA SIENNA. WHILE DRIVING WITH THE CRUISE CONTROL ENGAGED AND THE VEHICLE ACCELERATED BEYOND THE SET SPEED. WHEN THE VEHICLE WILL DECREASED IN SPEED THE SENSORS DETECTED ANOTHER VEHICLE APPROACHING. THE CONTACT SWITCHED LANES AND THE VEHICLE WOULD START TO ACCELERATE UP TO 10 MPH BEYOND THE SET SPEED. AFTER THE VEHICLE HAS PASSED THE APPROACHING VEHICLE, THE VEHICLE WILL DECREASE BACK TO THE SET SPEED. THE CONTACT HAS NOT CONTACTED THE MANUFACTURER. THE FAILURE MILEAGE WAS 25,000.

I HAVE A 2004 TOYOTA SIENNA AND THE REAR PASSENGER SLIDING DOOR IS MOTORIZED. A FEW DAYS AGO, SOMETHING WITHIN THE MOTOR THAT OPENS THE DOOR BROKE. IF IT HAD BEEN A CASE OF THE MOTOR WEARING OUT, I WOULD HAVE BEEN FINE WITH IT, BUT WHEN IT BROKE, IT PREVENTED THE DOOR FROM OPENING MORE THAN 3 INCHES, WHICH I BELIEVE TO BE A SAFETY HAZARD. THE INTERESTING THING ABOUT THIS IS THAT THE PART TO REPLACE IT COST ROUGHLY $1100 FROM TOYOTA, AND WHEN THE MECHANIC CALLED FOR THE PART, HE SAID THAT TOYOTA HAD 5 OF THEM IN STOCK. HIS COMMENT WAS THAT NO ONE KEEPS FIVE OF A $1100 PART IN STOCK UNLESS THEY KNOW THEY ARE GOING TO NEED IT. WHEN I SEARCHED THE INTERNET, I FOUND A LOT OF POSTINGS FROM OTHER PEOPLE EXPERIENCING SIMILAR ISSUES. SEEMED LIKE THERE MIGHT BE MORE OF THESE CASES OUT THERE, AND SINCE THE SAFETY OF PASSENGERS IN THE REAR SEEMED LIKE THEY COULD HAVE BEEN COMPROMISED WITH THE DOOR UNABLE TO BE OPENED. *TR
