The third row passenger side split was stored and then put back up. Upon lifting the seats, pieces fell out (spring, washer, and screw) and the locking mechanism would not lock the seats into place. I am not sure how long these parts were loose, but it is a major safety hazard as the vehicle seat was not secured to the car as intended. We plan to to follow up with Toyota, but upon investigating, it seems that this is an issue for several 2011 Siennas. My Sienna was manufactured 4/2012. This is the smaller of the split seats, but out of an abundance of caution, we don't plan to use the 3rd row at all until a remedy is produced. Unfortunately, I saw only consumer complaints in regards to the 2011 3rd row seating issue and didn't see any solutions.

The last week of September 2021 my husband notice a sound like water runing and a leak on the driver and passenger seats, we take the vehicle to the Dealer for an inspection on October 2nd. They said the AC hose was clogged for a spiderweb and the leak can create a mold. This mold can affect my family health. We informed to the insurance and we taked the vehicle to the Dealer for repair. They did an expensive special cleaning to Remove the mold, and disamble my entire vehicle, the worse is my vehicle still unassembled after 3 months at the dealership. All this happens with out any warning sign, symptoms or light. This vehicle is 3 years old and all services on time and by the same Dealership. My vehicle has a lot of technology but not warning about this AC clogged and damage my entire vehicle wich still on repair.

THIS IS A MAJOR ISSUE THAT COULD LEAD TO DEATH FOR THE THIRD ROW PASSENGERS. THE LEGS OF THE THIRD ROW DO NOT LOCK INTO THE FLOOR ALL THE TIME. PLEASE SEE PICTURES IT WILL CLARIFY THE ISSUE. IN CASE OF REAR END THE SEATS COULD ROTATE BACK AND THE PASSENGERS COULD HAVE A DIRECT HIT TO THE TOP OF THE HEAD.

3RD ROW POWER SEATS ARE MALFUNCTIONING AND ARE OPERATING WHILE VEHICLE IS IN MOTION. MULTIPLE TIMES, AND ON DIFFERENT DAYS, THE POWER SEATS HAVE STARTED TO CLOSE WHILE PASSENGER IS SEATED AND BUCKLED IN THE SEAT. OCCURRED TODAY WHILE ON THE HIGHWAY, AT HIGHWAY SPEED WHILE MY WIFE WAS SEATED IN THE DRIVERS SIDE 2 SEAT SPLIT. THE SEAT STARTED TO CLOSE ON ITS OWN - NO ONE TOUCHED ANY BUTTON AND WE HAD BEEN DRIVING FOR OVER AN HOUR. THE SEAT PUT PRESSURE ON HER UNTIL IT STOPPED IN A PARTIALLY CLOSED POSITION. THE SEAT BUTTONS THEN DID NOT WORK TO REOPEN THE SEAT BACK FOR SEVERAL MINUTES. THIS WOULD BE EXTREMELY DANGEROUS FOR A SMALL CHILD. THIS HAS HAPPENED IN A SIMILAR SCENARIO ON MULTIPLE OCCASIONS AND WE ARE CERTAIN THAT THE POWER SEATS ARE MALFUNCTIONING.

THE OCCUPANT SENSING SYSTEM DOES NOT RECOGNIZE THAT SOMEONE (FULL GROWN ADULT) IS SITTING IN THE PASSENGER SEAT. THIS PROBLEM IS IDENTICAL TO A PREVIOUS RECALL (NHTSA CAMPAIGN # 13V014000) TOYOTA SAYS THEY DO NOT HAVE TO FIX IT UNDER THE RECALL. PERHAPS THE RECALL DOES NOT COVER ALL OF THE VINS IMPACTED.

I HAVE A QUESTION REGARDING VEHICLE SEAT MOVEMENT. I HAVE BEEN TOLD BY TWO DEALERSHIPS THAT THE SEATS IN THE THIRD ROW OF THE TOYOTA SIENNA ARE MEANT TO HAVE SOME PLAY TO THEM. MY MAIN CONCERN IS THAT WITH A COUPLE OF CAR SEATS IN THE THIRD ROW, OR A COUPLE OF PASSENGERS, THE MOVEMENT OF THE SEATS MAY BE AN ISSUE. ALL FOUR SEAT LATCHES ROTATE WHEN LIFTING ON THE SEAT BY HAND, ALLOWING THE SEAT TO TWIST, MOVE TO THE REAR OF THE VEHICLE AND MOVE LATERALLY. THIS WOULD BE LESS OF A CONCERN IF THE SEATS THEMSELVES WERE NOT THE MOUNT FOR THE LATCH SYSTEM AND SEAT BELTS. MY QUESTION IS, WHAT MOVEMENT IS ALLOWED OF THESE SEATS? IN AN ACCIDENT, A HUGE AMOUNT OF FORCE CAN BE EXERTED ON THESE LATCHES, AND IF THEY ALLOW PLAY, THAT FORCE CAN BE MULTIPLIED BY THAT MOVEMENT. THE INCREASE IN FORCE COULD POTENTIALLY CAUSE THE LATCHES TO FAIL. CURRENTLY THERE IS NO SAFETY TEST FOR THIRD ROW OCCUPANTS OR REAR END COLLISIONS, FROM WHAT I HAVE RESEARCHED. THE ATTACHED FILES SHOW THE ACCESSIBLE LATCHES, AND THEIR MOVEMENT WHEN FORCE IS APPLIED TO THE SEAT.

I DON'T HAVE A QUALITY ISSUE. MY PROBLEM IS THE HEADRESTS THAT HAVE TO MEET NHTSA REQUIREMENTS. WHEN I DRIVE MY CAR, THE HEADRESTS KILL MY NECK! I'M NOT EVEN UNDER A DOCTOR'S CARE, BUT I MAY HAVE TO BE, IF I KEEP THIS VEHICLE AS LONG AS I EXPECT TO. PLEASE CONSIDER REVISING THE HEADREST REQUIREMENTS. I THINK THERE MAY BE AN UNTOLD NUMBER OF CONSUMERS WITH NECK AND SPINAL PROBLEMS DUE TO THIS MANDATE.

WHEN ATTEMPTING TO INSTALL MY FORWARD FACING CAR SEAT USING LATCH, I'VE NOT BEEN ABLE TO LOCATE THE HOOK FOR THE TOP TETHER, THAT SHOULD BE LOCATED BEHIND EACH OF MY 2ND ROW SEATS. DESPITE CHECKING THE MANUFACTURERS MANUAL, I WAS MERELY ABLE TO LOCATE WHAT FELT LIKE A HOOK THAT IS COMPLETELY COVERED BY FABRIC. NOT KNOWING ANY BETTER, I MISTAKENLY HOOKED THE TETHER STRAP TO ANOTHER HOOK THAT WAS LOCATED BEHIND THE SEAT. IN COMPLETING A CPST COURSE, I'VE LEARNED THAT THIS PRACTICE COULD HAVE SIGNIFICANTLY INJURED OR KILLED MY CHILD IF WE HAD BEEN INVOLVED IN A WRECK. MY CPST INSTRUCTORS AGREED WITH MY SUSPICION THAT THERE IS A DEFECT IN THE CONSTRUCTION OF THESE SEATS, AND THAT THE TETHER BAR SHOULD NOT BE COMPLETELY COVERED BY FABRIC. MY FEAR IS THAT OTHER FAMILIES WITH THIS VEHICLE ARE PUTTING THEIR CHILDREN AT RISK OF INJURY OR DEATH BECAUSE THEY AREN'T UTILIZING THE TOP TETHER SIMPLY BECAUSE THEY CAN'T ACCESS THE BAR FOR IT.

PASSENGER SEAT WARMER WAS ON THE OTHER DAY WHILE I WAS DRIVING AND BEGAN SMOKING AND MELTED THE SEAT IN THE SHAPE OF A DIME. FOR A COUPLE WEEKS IT WAS CAUSING BURNING FEELING IN LEGS FROM BEING TOO HOT. I TURNED OFF SEAT WARMER AND HIT THE SEAT UNTIL THE SMOKING STOPPED.

I WAS COMPLETELY STOPPED IN MY SIENNA AWD AT A TRAFFIC LIGHT AT THE TOP OF A FREEWAY ON-RAMP IN A MAJOR CITY, AND REAR-ENDED BY A VEHICLE BEGINNING TO TRAVEL DOWN THE ON-RAMP AT AN UNKNOWN BUT HIGH RATE OF SPEED AND NOT HEEDING THE TRAFFIC SIGNAL. ON IMPACT, THE REAR CARGO COMPARTMENT OF MY SIENNA CRUSHED INWARD SO FAR THAT IT CAUSED THE THIRD ROW BENCH SEAT TO MOVE FORWARD AND PROPEL THE SEAT PART OF THE BENCH SEAT INTO THE BACKS OF THE SECOND ROW CAPTAIN'S CHAIRS IN FRONT OF IT. THIS WOULD HAVE CRUSHED THE LEGS AND MAYBE WHOLE BODY OF ANYONE SEATED IN THE OUTER TWO SEATS OF THE REAR BENCH SEAT, AND PERHAPS IN THE MIDDLE POSITION AS WELL. I FOUND A PIECE OF PAPER BAG CAUGHT BETWEEN THE BOTTOM SEAT EDGE OF THE BENCH SEAT AND THE BACK OF A CAPTAIN'S CHAIR, AND I COULD NOT PULL THAT PIECE OF PAPER FREE. I HAD TO PULL REALLY HARD TO REMOVE THE LARGE PACK OF TOILET TISSUE, SHOWN IN THE UPLOADED PHOTO, IN ORDER TO DISLODGE IT FROM THE REAR BENCH SEAT AREA. THE TISSUE PACK LIKELY IS NARROWER THAN THE TRUNK OF AN ADULT HUMAN BODY WHICH COULD HAVE BEEN CAUGHT THERE, WITH LEGS ALSO CRUSHED BY THE LOWER PORTION OF THE BENCH SEAT AS IT IMPACTED THE BACK OF THE CAPTAIN'S CHAIR IN FRONT OF IT. I BELIEVE THE CAUSE OF THIS SAFETY PROBLEM IS A POOR DESIGN; INADEQUATE REAR-CRASH PROTECTION FOR THIRD-ROW PASSENGERS, WHO USUALLY ARE CHILDREN. AS A PARENT AND VEHICLE OWNER, I WAS NEVER WARNED ABOUT THE GREAT DANGER MY CHILDREN COULD BE IN IF THEY SEATED ANYWHERE ALONG THE THIRD-ROW BENCH SEAT DURING A REAR-END COLLISION. I'M TRAUMATIZED BY THE THOUGHT OF A CHILD OR ANYONE HAVING BEEN SEATED IN THE THIRD ROW AT THE TIME OF THIS COLLISION, WHICH FORTUNATELY THEY WERE NOT IN THIS INSTANCE.

THERE IS A RATTLING THAT COMES FROM THE 2ND ROW SEATS. IT IS LOUD AND DRIVING ME CRAZY. I SEE HUNDREDS OF COMPLAINTS ON TOYOTA FORUMS BUT TOYOTA WILL NOT ACKNOWLEDGE THE ISSUE, SOUNDS LIKE I AM DRIVING A CLUNKER INSTEAD OF A $35,000 CAR. I PURCHASED NEW AND THIS HAS BEEN GOING ON FOR SEVEAL YEARS

WITH SECOND CENTER SEAT INSTALLED (8-PASSENGER VAN), THE RECLINER COULD NEVER AUTOMATICALLY COME BACK UP WHEN PULL THE LEVER. DEALER INSPECTED IT AND DIDN'T FIND ANY ISSUE. HOWEVER, IT IS NOT NORMAL TO PULL THE LEVER AND SEAT BACK UP AT THE SAME TIME, ESPECIALLY WHEN SITTING ON THE CHAIR.

TAKATA RECALL ON MY 2011 TOYOTA SIENNA. I PURCHASED THE VAN NEW IN PHARR TEXAS WHICH IS AT THE SOUTHERN TIP OF TEXAS, TEN MINUTES FROM THE MEXICO BOARDER. THE CLIMATE HERE IS HOT WITH NORMALLY HIGH HUMIDITY. IT IS MY UNDERSTANDING I SHOULD HAVE BEEN CONTACTED BY TOYOTA AND AT THE VERY LEAST BE ON A WAITING LIST FOR PARTS TO ADDRESS THE RECALL. WHEN I APPROACH THE DEALERSHIP I'M TOLD; "NOTHING CAN BE DONE, WE ARE WAITING ON PARTS." NO ONE WRITES ANYTHING DOWN, NO ONE SHOWS ME THAT THERE IS A LIST AND THAT I'M ON THAT LIST. NOTHING SEEMS TO BE HAPPENING TO ADDRESS THE ISSUE. I KEEP MY VAN GARAGED AND IN LIKE NEW CONDITION. IT HAS VERY LOW MILEAGE AND I PLAN TO KEEP IT FOR AT LEAST ANOTHER FIVE YEARS. I NEED HELP IN GETTING THIS SAFETY RECALL ADDRESSED IN A TIMELY MANNER. THANK YOU!
