2012 Toyota Sienna Problems

I was at a full stopped and rear Ended at 30 miles an hour and the air bags did not deploy and I am suffering many injuries pain and loss The air bags didn’t deploy at all

BROUGHT CAR IN FOR AIRBAG SAFETY RECALL. WAS TOLD IT WAS COMPLETED. AFTER THIS RECEIVED ANOTHER RECALL MAILING FOR THE SAME PROBLEM. CALLED THE TOYOTA RECALL RESOLUTION TEAM NUMBER TO VERIFY. WAS TOLD THAT A TEMPORARY AIRBAG WAS INSTALLED AND THAT I NEEDED TO HAVE THE GOOD ONE REINSTALLED WHEN THEY GOT THEM IN. SHE CALLED THE DEALER TO SET UP AN APPOINTMENT THEN TOLD ME THAT IT WAS TAKEN CARE OF AND A NEW AIRBAG WAS NOT NEEDED. AND STATED THAT SHE WAS CONFUSED. AND THAT I NEEDED TO GO BACK TO THE DEALER TO GET A WRITTEN STATEMENT THAT THE WORK WAS DONE. I NOTICED AND EXPLAINED THAT IT LOOKS LIKE A SUBSTITUTE WAS MADE AND THE RECEIPT SAYS : 'BAG 0.8. 2007-2009 YARIS HATCHBACK 2007-2009 YARIS SEDAN'. SO IT LOOKS LIKE A TEMPORARY SUBSTITUTE WAS MADE AND THAT I WAS NOT INFORMED. I SAID THAT IF THEY GIVE WRITTEN DOCUMENTATION THAT THE REPAIR WAS MADE IT MAKES IT LEGALLY THEIR RESPONSIBILITY BUT THIS WOULD BE AFTER THE FACT IF A PROBLEM OR FATALITY WOULD OCCUR AND NOT SOLVE THE ISSUE OF ASSURING THAT A PROPER AIRBAG HAD BEEN INSTALLED. CAN YOU GIVE CLARIFICATION AND SUGGESTED FOLLOW UP (POSSIBLY THIRD PARTY) TO GUARANTEE SAFETY?

The automatic side doors of this Toyota sienna le have malfunctioned twice between expensive repairs. When the hardware comes off the guide rail, it hits the window behind the door and shatters in covering the interior and occupants with glass. I had the window repaired after I had the door hardware replaced after its first failure in spring of 2024. The door gave no indication it was failed until I noticed the window bulging and nearly broke again. The Toyota dealer didn’t seem very interested in covering the cost of the repairs I made in 2024 and can’t get me in until mid August which leaves me without transportation for a month.

The contact owns a 2012 Toyota Sienna. The contact was unable to use the driver's side cargo door. The contact stated that the door was possibly frozen; however, while driving at an undisclosed speed, the door opened unexpectedly. The contact referenced NHTSA Campaign Number: 16V858000 (Structure); however, the VIN was not associated with the recall. The dealer was not contacted, and the vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 201,235.

Odometer Fraud. The contact purchased a 2012 Toyota Sienna. The contact discovered a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 48,230. It was later discovered that the mileage on the Title was 241,080.

The power sliding door cables snap by itself and unable to open or closed. While my children and I were in the vehicle.

Rear axle coupler assembly (part number 41303-28013) making very loud noise and vibration.

The contact owns a 2012 Toyota Sienna. The contact stated that the rear differential was making an abnormal whirling and grinding sound. There were no warning lights illuminated. The contact called the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to NHTSA. The approximate failure mileage was 79,000.

The battery light came on suddenly and the power steering went out making it extremely difficult to steer the vehicle. An accident was narrowly avoided. We replaced the battery, alternator, and serpentine belt. The problem resolved for over 6 months, then reappeared. It starts with no issue, is charging properly, the serpentine belt is intact. The power steering will come on and go off sporadically, the only warning being the battery indicator on the dash that comes on first. This creates a substantial hazard and risk as the steering is severely impacted with little warning.

My wife let me know that when turning to the right (not an aggressive turn, but a normal turn from one lane to the next), the whole electrical system of the minivan would shut down and then come back on. I had a mechanic check it out and they say that this is due to the electrical steering system and will have to be replaced by the dealer. He was able to reproduce the same condition where he was able to get the minivan to lose power when changing lanes. He STRONGLY advised that we should have the vehicle towed to the dealer as he felt that it wasn't safe to drive due to this. I feel that this will end up causing a lot of crashes and also that this should be covered by the manufacturer under a recall.

WHEN PRESSING THE BRAKE THE ENGINE REVS SUDDENLY AND TO VERY HIGH RPMS AND YOU HAVE TO PRESS DOWN ON THE BRAKE AND/OR THROW CAR INTO NEUTRAL/DRIVE AND THEN EVENTUALLY THE ISSUE RESOLVES. HAPPENED YESTERDAY WHEN REVERSING VERY SLOWLY OUT OF DRIVEWAY--WAS PRESSING BRAKE (NOT ACCELERATOR) AND SUDDENLY THE ENGINE GOT VERY LOUD AND WAS REVVING UP. PRESSED BRAKE HARD AND THRU THE CAR INTO PARK AND PRESSED THE ACCELERATOR AND THE ENGINE WENT BACK TO NORMAL. VERY SCARY. HAS HAPPENED SEVERAL TIMES BEFORE AND FORTUNATELY WE HAVE NOT RUN INTO ANYTHING AND THE CAR HAS NOT TAKEN OFF AT HIGH SPEED.

On 8/22/2022 I had to replace the 2 front tires with MIM-Supreme Tour 18 inch tire 235/55R18. On 8/22/2022 I had 162,323 miles on the 2012 Toyota Sienna XLE 4 months later and 17,252 miles driven - the 2012 Toyota Sienna now has 179,575 miles and on 12/28/2023 the 2 front tires again have to be replaced - Matrix Toyr RS 11 on 18 inch rims. Now its July 2024 - again 6 months and now 6,700 miles and just the front tires are bald and dangerous to drive if any moisture on the road. All these tires are slated for 50,000 miles and I and not getting even half the mileage. Most driving is on highways and regular maintenance occurs on the car. this car should be designed to go at least 25,000 miles ( so once a year ) on a set of tires. I do not drive fast nor aggressive.

WE REALIZED THAT OUR VEHICLE HAD A FLAT TIRE. WHEN WE WENT TO ATTEMPT TO PUT ON THE SPARE, WE NOTICED THAT ALL OF THE LUG NUTS HAD "SWOLLEN" AND NONE OF THE LUG NUTS WOULD FIT IN THE CORRESPONDING SOCKET. ULTIMATELY, THE LUG NUT CAPS DELAMINATED, AND IT TOOK OVER AN HOUR TO TEAR THE CAPS FROM THE NUTS. IF THIS HAD HAPPENED ON THE SIDE OF THE HIGHWAY, ADDRESSING THIS ISSUE WOULD HAVE BEEN INCREDIBLY DANGEROUS. IT DOES NOT SEEM TO MAKE SENSE TO CONTINUE USING LUG NUTS WITH DECORATIVE CAPS FOR AESTHETIC REASONS WHILE IMPACTING THE SAFETY OF DRIVERS WITH FLAT TIRES.

My 2012 Toyota Sienna having problem while braking on highway 65mph or above, when i hit brake it's start shaking so bad and brake doesn't work properly. i believe it is sway bar link or lower control arm. even i had replaced once, it didn't helped and again i claimed warranty and replaced other set, but still having same issue.

The vehicle stability control activates and causes the car to slow and brake randomly. This occurs at low speeds and when the car is not skidding.

Coolant leaking from rear of the engine through the head gasket. Vehicle struggles to accelerate beyond 55mph or 80kmph. A quick search on the internet shows that this is a frequent occurrence in this 3.5L V6 engine from Toyota model years 2011 through 2017.

The engine stalled, power steering frozen then engine shut off while driving in an intersection. Replaced new battery, dove home upon arrival the engine stalled again, power steering frozen and engine shut off again. I don’t know what’s going on.

THIS CAR CAUGHT ON FIRE FEW MINUTES AFTER SOME ELECTRICAL ISSUES- WHILE DRIVING THE CAR WITH EVERYTHING LOOKING JUST FINE , THE A/C FAN FLUCTUATED ON AND OFF -CAR BLUE TOOTH ALSO KEPT DISCONNECTED AND RECONNECT FOR A FEW SECONDS THEN ALL DASHBOARD LIGHTS ILLUMINATED ON AND OFF FEW TIMES . AFTER MAYBE 2 MINUETS I REACHED HOME ,MAY FAMILY GOT OFF THE CAR WHEN I NOTICED SMOKE COMING FROM THE HOOD . I OPENED THE HOOD TO FIND A MEDIUM SIZE FIRE COMING FROM THE DRIVER SIDE OF THE ENGINE, I CALLED 911 RIGHT AWAY . IN LESS THAN 10-15 MINS MOST OF THE CAR MELT FROM THE FIRE PLUS THE WHOLE GARAGE.

MAKING A RIGHT HAND TURN AND I BELIEVE THE TRUCK IN FRONT OF ME LOST THE TRAILER HITCH. I WAS ONLY TRAVELING ABOUT 15 MPH. DROVE OVER A TRAILER HITCH IN THE ROAD AND ALL THE AIRBAGS DEPLOYED, CAUSING A VIOLENT STOP TO THE VAN AND INJURIES AND SHOCK TO MY DAUGHTER AND MYSELF

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 TOP HINGE OF THE FUEL FILLER DOOR BROKE AT 82000 MILES. IT NOW DOES NOT ALLOW THE AUTOMATIC SLIDING DOOR ON THE DRIVERS SIDE TO OPEN BECAUSE OF THE SAFETY MECHANISM. THE HINGE BROKE WHEN I OPENED THE DOOR DURING REFUELING.

THE PASSENGER SIDE HEADLIGHT TURNS OFF INTERMITTENTLY. IT WILL TURN ON AGAIN IF YOU TURN THE HEADLIGHTS OFF AND BACK ON, BUT THEN WILL GO OUT AGAIN. I HAVE READ ONLINE ABOUT MANY OTHER TOYOTA OWNERS, SPECIFICALLY THOSE WITH PRIUSES, BUT ALSO SOME SIENNAS, HAVING THIS PROBLEM. DEALERS DON'T KNOW HOW TO RESOLVE IT - MINE WANTS TO REPLACE THE BULB FOR CLOSE TO $500, BUT CAN'T GUARANTEE THIS WILL RESOLVE THE PROBLEM AND THE BULB IS APPARENTLY WORKING, JUST NOT ALL THE TIME. THIS IS A SAFETY ISSUE TO HAVE A NON-WORKING HEADLIGHT. *TR

NO DASHBOARD LIGHTS WHEN VAN IS STARTED, ONLY COME ON WHEN LIGHT SWITCH IS ACTIVATED. DASHBOARD ON VISIBLE ON CLOUDY DAYS. *TR
