I HAD TROUBLE ACCELERATING UP A HILL AND STALLING AND TURNING OFF ON THE ROAD. I TOOK MY VEHICLE TO MY TOYOTA DEALERSHIP FOR INSPECTION AND WAS TOLD THAT RODENTS OR SUCH TYPE HAD CHEWED ON THE ELECTRICAL WIRING HARNESS BECAUSE OF THE INSULATION MATERIALS ATTRACTIVENESS. AFTER BEEN FIRST OFFENDED, I THEN REMEMBERED SEEING A SQUIRREL NEAR THE VEHICLE I PRESUMED INNOCENTLY TAKING SHADE FROM THE HOT FLORIDA SUN. DURING THAT TIME I PARKED MY VEHICLE IN MY DRIVEWAY OUTSIDE. I ADVISED THE DEALERSHIP OF THIS AND THEY CONFIRMED THAT INDEED SUCH ANIMAL WOULD LIKING HAVE CHEWED ON THE HARNESS WIRING CAUSING THE ISSUE AT HAND. I PAID OUT OF POCKET FOR THIS REPAIR SINCE I WAS TOLD IT WAS NOT UNDER WARRANTY. IT HAS COME TO MY ATTENTION THAT THE TOYOTA DEALERSHIP WAS AWARE OF THIS TYPE OF ANIMAL AND THE ATTRACTION TO THE SOY BASED INSULATION AROUND THE ELECTRICAL WIRING HARNESS. THERE NOW ARE TWO CLASS ACTION CASES REGARDING THIS MATTER WITH TOYOTA.
THIS CAR IS EXPERIENCING SUA. IT HAPPENED IN A PARKING LOT AN RESULTED IN A CRASH INTO A CEMENT WALL. IT ALSO HAPPENED ON A WINDING MOUNTAIN ROAD.
SUSPENSION COIL SPRINGS BREAK AT VERY LOW MILEAGES (AROUND 40K OR 50K MILEAGES) IMPAIRING RIDE, STEERING AND BRAKING MAKING THE VEHICLE UNSAFE TO DRIVE. BESIDES THE SUSPENSION COIL SPRINGS CORRODING, THERE SEEMS TO A LARGER PROBLEM OF THE ENTIRE UNDERBODY CORRODING WITH THE TOYOTA SIENNAS.
PASSENGER SIDE SLIDING DOOR HAS SNAPPED CABLE. VAN WAS PARKED AND BUTTON WAS USED TO OPEN DOOR. HEARD POP/CRUNCH SOUND. WAS ABLE TO FORCE DOOR SHUT. DOOR IS UNABLE TO BE OPENED AND REMAINS CLOSED; EVEN WHEN POWER SLIDING DOOR OPTION IS TURNED OFF. NO DAMAGE SEEN INSIDE OR OUTSIDE OF VEHICLE.
PASSENGER SIDE RACK AND PINION LEAKING FLUID WAS DISCOVERED AT DEALERSHIP WHEN VEHICLE WAS IN FOR SERVICE.

OUR TOYOTA SIENNA HAS 2 SEAT BELTS THAT WILL NO LONGER FUNCTION PROPERLY. WE CONTACTED TOYOTA (CASE# 1609160545) TOYOTA REFUSES TO STAND BEHIND THIS SAFETY RELATED FAILURE. THIS IS OUR FAMILIES MAIN TRANSPORTATION AND WE KEEP IT MAINTAINED. HOWEVER, THIS IS NOT A MAINTENANCE ISSUE. A VEHICLE MANUFACTURER HAS AN INCUMBENT DUTY TO DELIVER A PRODUCT THAT IS SAFE FOR CONSUMER USE. I FIND IT VERY CONCERNING TOYOTA FEELS IT IS NOT NECESSARY TO OFFER SEAT BELTS THAT WILL OPERATE PROPERLY FOR THE LIFE OF THEIR CUSTOMERS VEHICLE. WE HAVE SEATS WE CAN'T PUT OUR CHILDREN IN DUE TO THE FACT, THERE IS NO RESTRAINTS TO KEEP THEM SAFE. IT'S UNCONSCIONABLE.
STRUTS ON THE REAR DOOR ARE FAILING. THE DOOR COMES DOWN WHENEVER IT WANTS TO. THIS IS A SAFETY ISSUE AND VERY DANGEROUS. I SEE YOU HAVE HAD A RECALL ALREADY BUT IT DOESN'T LIST MY SPECIFIC YEAR. FAILING STRUTS IN 2008 ARE FAILING. I WANT TOYOTA TO FIX THIS FOR FREE.

POWERED PASSENGER DOORS ON BOTH SIDES OF THE VAN MALFUNCTIONED AND THEN CABLE SYSTEM BROKE AND LOCKED THE DOORS IN THE CLOSED POSITION. THIS HAPPENED ONE AFTER THE OTHER IN ABOUT A THREE-WEEK PERIOD. THE CABLE IS CLEARLY RUSTED AND SHREDDED ON THE ONE SIDE. I CANNOT TELL WHY THE CABLE PULLED OUT AND STOPPED WORKING ON THE OTHER SIDE. AS I TRANSPORT 3 OR MORE CHILDREN AT A TIME, IT IS A HUGE SAFETY ISSUE THAT THE ONLY WAY OUT OF THE CAR IN CASE OF EMERGENCY IS THROUGH ONE OF THE FRONT DOORS OR THE BACK TRUNK HATCH. I HAVE OWNED THIS VEHICLE SINCE IT WAS NEW AND I AM TOLD THIS IS OUT OF WARRANTY/ISN'T COVERED AND WILL COST AT LEAST $6,000 TO FIX. I CANNOT DRIVE THE VEHICLE LIKE THIS AND I CAN'T AFFORD TO FIX IT. I AM APPARENTLY NOT THE ONLY ONE WHO'S HAD THIS PROBLEM WITH THE VAN, YET TOYOTA IS DOING NOTHING ABOUT IT FOR THEIR CUSTOMERS.

Additionally, model year 1998-2003 Siennas were recalled as part of safety recall 10V-160.
