Structure

“The contact owns a 2007 Toyota Sienna. The contact stated that the liftgate fell on him as he was loading items into the trunk of the vehicle. The contact moved out of the way as the liftgate proceeded to close independently without warning. The contact was unable to stop the liftgate from independently closing. The dealer was notified of the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 114,000.”
Engine
42 reports3 fires
“As a result of the transmission cooler being a part of the radiator system, the transmission cooler ruptured while driving causing immediate loss of power and the engine to overheat. This malfunction also caused coolant and transmission oil to contaminate the engine compartment as well as the transmission. This is a major iengineering flaw and safety issue as I was on the interstate when it happened and was stranded on the side of the highway until help could be obtained.”
Air bags
37 reports7 crashes1 fire
“LAST WEDNESDAY MORNING ANOTHER CAR REAR ENDED MY SIENNA AT HIGH SPEED AT STOP SIGN WHILE I WAS WAITING FOR MY TURN TO PROCEED. I WAS TRAVELLING WITH MY FAMILY. SIENNA GOT TOTALED DUE TO THIS. SIDE DOORS, BACK DOOR, BACK BUMPER, CARGO AND THIRD ROW SEAT AREA ALL GOT IMPACTED DUE TO THIS AND EVERYTHING CAVED INWARD BY FEW INCHES. MY ENTIRE FAMILY HAS BEEN SHAKEN TO THE CORE AND ME AND MY WIFE ARE SUFFERINGS FROM SEVERE PAIN IN BACK AND NECK SINCE THE ACCIDENT. THE CABIN WAS FILLED WILL WHITE SMOKE (POWDERY STUFF), BUT NO AIR BAGS GOT DEPLOYED (OPENED) DUE TO THE IMPACT. WE ARE LUCKY THAT WE ALL ARE STILL ALIVE SINCE WE HAD BEEN HIT FROM THE BACK AT HIGH SPEED. THE CAR HITTING US FROM THE BACK MUST BE TRAVELLING ABOVE 40 MILES AN HOUR SINCE MY FULLY LOADED SIENNA WITH 3 ADULTS AND A CHILD SKID FORWARD BY ALMOST 8-10 FEET. THIS IS A SERIOUS CONCERN THAT EVEN AFTER SUCH A HIGH IMPACT COLLISION, NONE OF THE AIR BAG OPENED. THE VEHICLE WAS STATIONARY, ON A HIGHWAY AT A STOP SIGN (RIDGE RD AND ROUTE 52 JUNCTION IN KENDALL COUNTY, IL). I HAVE ATTACHED THE POLICE REPORT AND ALSO THE REAR OF MY CAR. IT RENDERED MY CAR UNDRIVABLE AND I HAD TO GET IT TOWED TO THE GARAGE.”
Power train
31 reports3 crashes2 related recalls
“The contact owns a 2007 Toyota Sienna. While the contact’s wife was pulling into the parking space, the transmission shifter was shifted into park(P), and the vehicle suddenly rolled forward approximately four feet. The parking brake was activated, preventing the vehicle from crashing into a parked vehicle. The vehicle was towed to the residence. While examining the vehicle, the contact determined that the shifter cable bushing had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure. Additionally, previously while driving there was smoke coming from the engine compartment and the vehicle stalled. The vehicle was towed to the local mechanic who diagnosed the vehicle and determined that the oil cooler line had failed causing engine oil to spill from the engine. The rubber oil cooler line was replaced with an updated improved oil cooler line, and the vehicle was repaired. The failure mileage was 170,000.”
