2014 Toyota Sienna Problems

The passenger-side power sliding door system failed to stop or reverse when it encountered physical interference with the vehicle’s open fuel door. The door continued opening under power despite clear obstruction by a fixed exterior body component. The affected components, including the sliding door mechanism and damaged fuel door latch, remain available for inspection upon request. A powered sliding door continuing to operate against an obstruction creates a foreseeable risk of injury to occupants or bystanders, as well as vehicle damage. If a person’s hand, arm, or clothing had been in the same position as the fuel door, injury could have occurred. The incident occurred during normal vehicle use and demonstrates inadequate safeguards against obstruction. The issue has been formally reproduced or confirmed by an independent service center which noted that the incident occurred as described during normal operation of the power sliding door, and no abnormal conditions were present at the time. No warning lamps, messages, or other symptoms appeared prior to the incident. The power sliding door operated normally and without indication of malfunction until it failed to stop when encountering the open fuel door. Fueling the vehicle with the fuel door open is routine and expected vehicle use. The absence of any interlock, sensor logic, or safeguard preventing a powered sliding door from operating against an open body panel represents a design deficiency rather than a maintenance or wear issue. This condition may affect other vehicles equipped with similar power sliding door systems and warrants evaluation.

The contact owns a 2014 Toyota Sienna. The contact stated that while driving 70 MPH, there was an audible alarm coming from the vehicle, alerting the contact that the door was ajar. The passenger’s side slide door opened independently while the vehicle was in motion. The vehicle was modified to accommodate a ramp for the contact's two wheel-bound children. The contact pulled over to the side of the road and closed the sliding door. The contact's husband tied the door to prevent it from opening independently again. The check engine warning light was intermittently illuminated. The vehicle was taken to the dealer, where it was inspected. The contact was informed that two latches had corroded and needed to be replaced. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 16V858000 (STRUCTURE). However, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was approximately 99,500.

Dear sir/ madam, I am writing to report an issue with recall status reporting. All open recalls for my vehicle (VIN: [XXX] ) were completed at an authorized dealership on [01/27/2026]. I have documentation from the dealer confirming that the recall repairs were successfully performed. However, the recall status has not been updated in the NHTSA database and still appears as “open.” I request assistance in ensuring the recall completion is properly reported and reflected in the NHTSA system. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2014 Toyota Sienna (as indicated by VIN number) and I currently reside in the United Kingdom on US military orders. After getting notice from the NHTSA about the fact that my vehicle had an open recall I contacted my local Toyota dealership here in the UK. I was able to have the affected parts replaced after they were shipped from the US. However, the UK Toyota dealership has been unable to update the NHTSA database due to being outside the US. We have been trying to correct this issue through Toyota and the NHTSA for well over a year but no progress has been made. I have paperwork that shows the recall work was carried out. Please help me figure out how to get this updated. My family has received orders to return to the US but we are unable to ship our vehicle with an open NHTSA recall.

Tire pressure monitor system dashboard icon is ridiculously non-intuitive. Both my wife and daughter have been baffled by it because the icon DOES NOT LOOK LIKE A TIRE! Neither are stupid, one is a college grad and the other is a junior at ASU. The icon is a cross-section of a tire, and none of them know what a tire cross-section looks like. Because of this, they have driven on dangerously under inflated tires without knowing it. Fix the icon SO IT LOOKS LIKE A TIRE! Thank you.

The van seems to prematurely wear tires out before their service life expectancy. I've owned the van for seven years, and I've had to purchase over five complete sets of tires. The front tires wear-out much faster than the rear tires, and do not last more than 15K miles. I've had several alignment jobs done, both (L&R) control arms replaced, ball joints, and struts - the van still wears out tires regardless of tire brand. I suspect the must be a design flaw causing premature wear and tear on tires on the front of the van, as I just replaced another set of tires from the Yokohama brand recommended for the van. I've asked Toyota, and they claim ignorance of such a problem. It is my desire to make this problem known, and to have the Government investigate if there is an design flaw in the Sienna van which is causing rapid part failures.

Good question

The passenger side cable that opens and closes the door snapped and is disconnected. The door will get stuck in an open or closed position.

The contact owns a 2014 Toyota Sienna. The contact stated that while opening the driver’s side sliding door, the drive belt snapped. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the sliding door drive belt. The vehicle was not repaired. The contact also stated that the same failure later occurred on the passenger’s side sliding door. The manufacturer was not notified of the failure. The failure mileage was 155,000.

I HAD THE VEHICLE INSPECTED BY PERSONAL MECHANIC BECAUSE THE STEERING WHEEL WOULD TIGHTEN AND THEN RELEASE WHENEVER TURNED TO RIGHT AND RELEASE ON LEFT TURN. THIS WOULD HAPPEN ON A REGULAR BASIS WHEN TURNING THE WHEEL. THE MECHANIC DID RECOMMEND THAT I CALLED THE MANUFACTURER TO CHECK IF THERE WAS ANY RECALL FOR THE PROBLEM. WHICH I DID. RESPOND WAS NO AND SO I EXPLAINED THE PROBLEM TO THE REPRESENTATIVE. THERE IS NOT A FAILURE OR INCIDENT EXCEPT THE STEERING WHEEL KEEPS ON TIGHTENING AND I'M JUST BEING CAUTIOUS. NO MANUFACTURER, POLICE, OR INSURANCE HAS INSPECTED IT BECAUSE THERE IS NO ACCIDENT. THANK GOD! JUST CONCERNED BECAUSE MY MECHANIC SAID IT IS SOMETHING FOR THE DEALERSHIP. SOMETHING TO DO POSSIBLY WITHIN THE STEERING COLUMN/CHANNEL COMPONENT. NOT SURE WHICH IS RIGHT, BUT TO CHECK FOR RECALL BY MANUFACTURER. I TOOK IT TO TIRE KINGDOM BUT SOMETHING ELSE WAS REPAIRED. SO I'M STILL HAVING TROUBLE WITH STEERING WHEEL STIFF TIGHTENING UP LIGHTLY. I WOULD FEEL IT TIGHTEN WHENEVER DRIVING 45 MILES OR MORE.

The rear electro magnetic coupler had to be replaced at 120000 miles. Online multiple complaints are listed for the same issue and Toyota has a recall issues for the same component for the RAV4. So why not for the Toyota Sienna xle ltd awd Thanks

ON OCTOBER 15TH AT APPROXIMATELY 3:30 PM (CT) MY 2014 TOYOTA SIENNA WAS PARKED IN MY DRIVEWAY WITH THE ENGINE ON, UNATTENDED, WHEN IT MOVED FORWARD UP THE SLIGHT INCLINE OF MY DRIVEWAY, STRUCK ANOTHER VEHICLE THAT WAS PARKED IN THE GARAGE AND KEPT MOVING FORWARD UNTIL IT STRUCK THE FRONT WALL OF THE GARAGE. PRIOR TO THE ACCIDENT, I HAD REVERSED THE VAN OUT OF THE GARAGE AND LEFT THE VAN IGNITION ON AND IN PARK AS I EXITED. I KNOW FOR CERTAIN THAT THE VAN WAS IN THE PARK POSITION SINCE THE AUTOMATIC LOCKS LET ME EXIT THE VEHICLE WITHOUT HAVING TO MANUALLY UNLOCK THEM AND THE ALARMS DID NOT SOUND AS I EXITED. THE VAN ALSO DID NOT ROLL FORWARD IR BACKWARD AS I EXITED. I THEN WALKED IN FRONT OF THE VAN TO ENTER MY HOUSE THROUGH THE GARAGE. I WAS IN THE HOUSE FOR LESS THAN 5 MINUTES WHEN I HEARD THE LOUD CRASH OF THE VAN STRIKING THE GARAGE WALL. MY TOYOTA SIENNA WAS MANUFACTURED ON JUNE 6, 2014. AFTER THE ACCIDENT I DISCOVERED THERE IS AN ACTIVE RECALL (RECALL: TRANSMISSION SHIFT CABLE/ROLLAWAY/FMVSS 102) FOR AN ISSUE THAT CAUSES ROLLAWAYS EFFECTING CARS MANUFACTURED BETWEEN JUNE 17, 2014 THROUGH JUNE 24, 2014. I TOOK MY VAN TO TOYOTA EXPECTING MY ISSUE TO BE RELATED TO THIS RECALL. TOYOTA HAD THE BLACK BOX INSPECTED AND THE TRANSMISSION INSPECTED AND DETERMINED THEY WERE NOT LIABLE SINCE THEY WERE NOT ABLE TO REPLICATE THE ISSUE AND DID NOT FIND ANY DEFECTS. WHEN I TOOK MY CAR IN ORIGINALLY THE TECHNICIAN STATED THAT THERE WAS NOT A GOOD WAY TO DETERMINE IF THE SHIFT CABLE WAS DEFECTIVE AND THEY WERE SIMPLY REPLACING THE PART AS PART OF THE RECALL, WHICH MY CAR DID NOT QUALIFY FOR SINCE IT WAS MANUFACTURED 11 DAYS PRIOR. A CAR SHOULD NEVER MOVE ITSELF FROM THE PARK POSITION AND SOMETHING HAS TO BE FAULTY WITH THE CAR IN ORDER FOR IT TO DO SO.

TL* THE CONTACT OWNS A 2014 TOYOTA SIENNA. THE CONTACT STATED THAT THE SPARE TIRE CARRIER CABLE WAS RUSTED. THE CONTACT WAS CONCERNED THAT THE TIRE COULD DETACH FROM VEHICLE AND CAUSE AN ACCIDENT.

After a rain, water will leak into the driver and front passenger seatbelt coil housing. The front passenger seatbelt was not used in some time and mold developed with green and black stains all along the seatbelt. After it rained, the driver side seatbelt released about 1 cup of water when I pulled the seatbelt. With my wife as the passenger, she was conflicted about wearing the seatbelt while having mold pressed against her body, clothes, and breathing it in. The smell of mold is now present in the vehicle. This problem has been reproduced via online reports at SiennaChat.com. No warning lamps, messages or symptoms appeared prior, or during, this issue. I am in the process of reporting it to Toyota as soon as the next business day (Monday).

THE DRIVERS SEATBELT ON MY WIFE'S CAR STOPPED FUNCTIONING AND WILL NOT LATCH. NOTHING APPEARS TO BE STUCK IN IT. LOOKING INSIDE THE FEMALE PART, IT LOOKS LIKE IT HAS COME APART. THE VEHICLE HAS NEVER BEEN IN AN ACCIDENT. THE DEALER CANNOT EXPLAIN WHY IT BROKE.

TL* THE CONTACT OWNS A 2014 TOYOTA SIENNA. WHILE DRIVING APPROXIMATELY 65 MPH, A LOUD EXPLOSION WAS HEARD. THE CONTACT DISCOVERED THAT THE SUN ROOF EXPLODED. THERE WERE NO INJURIES. THE VEHICLE WAS TAKEN TO HOOVER TOYOTA (2686 JOHN HAWKINS PKWY, HOOVER, AL 35244) TO BE REPAIRED. THE CAUSE OF THE FAILURE WAS NOT DISCLOSED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 40,000.

DRIVER'S WINDOW SEAL COMES DETACHED WHEN WINDOW RETRACTS AND YOU CANNOT PUT WINDOW BACKUP USING CONTROL BUTTON AS SENSOR DETECTS INTERFERENCE \ RESISTANCE AND AUTOMATICALLY RETRACTS WINDOW TO OPEN POSITION. THIS CREATES A DANGEROUS SITUATION WHEN DRIVING AS ITS A MAJOR DISTRACTION TO THE DRIVER AS THE SEAL HANGS LOOSE AND CAN INTERFERE WITH UNOBSTRUCTED VIEWABILITY OF SIDE MIRROR. IN INCLEMENT WEATHER THIS IS A REAL DRIVING HAZARD. TEMPORARY FIX IS TO PULL UP ON WINDOW SEAL AND PUSH BACK INTO POSITION ESTIMATED FIRST TIME PROBLEM NOTICED. SORRY FOR SLOW REPORTING JUST FOUND THIS WEBSITE TO REPORT PROBLEM.

MY 2014 TOYOTA SIENNA DOES NOT HAVE THE DASHBOARD INSTRUMENT LIGHTS ON WHEN DRIVING. THE INSTRUMENT CLUSTER IS HOODED TO SHIELD IT FROM SUNLIGHT. AUXILIARY LIGHTING IS REQUIRED TO CLEARLY SEE AND READ THE DIALS AND INSTRUMENTS. NOT BEING ABLE TO QUICKLY AND EASILY READING THESE DIALS CAN BE A SAFETY ISSUE. THE ONLY WAY TO TURN ON THE DASHBOARD LIGHTS IS TO (1) TURN ON THE PARKING LIGHTS OR (2) TURN ON THE HEADLIGHTS. THIS IS CONTRARY TO OTHER VEHICLES WE HAVE OWNED, INCLUDING TOYOTAS. TOYOTA HAS TOLD ME THAT THIS IS STANDARD. I DISAGREE. I FEEL THAT TOYOTA SHOULD TURN ON THE INSTRUMENT LIGHTS WHEN I START THE ENGINE. . *TR

THERE IS NO ILLUMINATION OF THE MAIN DASHBOARD DISPLAY-SPEED, RPM, TEMPERATURE AND FUEL LEVEL WHEN LIGHT CONTROL IS AT OFF OR DRL (DRIVING LIGHTS) POSITION. I WENT TO DEALER AND SERVICE MAN SAID THAT IS THE WAY IT IS AND ANOTHER NEW VEHICLE ON THEIR LOT WAS THE SAME. THE GAUGE LIGHTS ARE ON BUT DIM IN PARKING AND HEADLIGHT POSITION. (TOYOTA MANUAL SAYS USE DRL IN DAYTIME TO SAVE FUEL AND ELIMINATE CHANCE OF BURNING OUT DRIVING LIGHTS.) I CALLED TOYOTA AND THEY SAID AFTER 2 WEEKS OF INVESTIGATION THAT THIS IS THE WAY IT IS. THIS IS A SAFETY ISSUE BECAUSE WE CANNOT SEE THE SPEED ON CLOUDY DAYS OR WITH SUNGLASSES ON SUNNY DAYS. MY PREVIOUS TOYOTA- 2006 SIENNA AND 2013 AVALON HAVE ILLUMINATION ANYTIME THE IGNITION IS ON FOR DRIVING. WHEN YOU CAN'T SEE THE SPEED EASILY, THIS IS A SAFETY RISK- THERE IS NO DIGITAL DISPLAY OF SPEED ON THIS VEHICLE. *TR
