  I AM HAVING TO REPLACE ALL THE TIRES, WITH ONLY 19,903 MILES ON MY AWD 2017 MINIVAN. AT MY 10,000 MILE TOYOTACARE CHECK, THEY DIDN'T ROTATE THE TIRES BECAUSE THEY SAID NO ROTATION NEEDED DUE TO LESS TREAD ON BACK TIRES, SO ALREADY NOTICING UNEVEN WEAR. AT 15000, THEY ONLY ROTATED ONE SIDE. NOW AT 20,000 THEY TELL ME THE FRONT TIRES SHOW INNER SHOULDER WEAR. THEY DID ROTATE. HAD AN INDEPENDENT DOUBLE CHECK. THE TIRES THAT HAD BEEN ON FRONT ARE VERY WORN/SMOOTH ON INNER SIDE, TREAD LESS THAN 5 IN THE MIDDLE. THESE ARE THE TIRES THAT CAME ON THE MINIVAN WHEN I BOUGHT IT, BRAND NEW. THEY ARE RUN FLAT TIRES. THEY COST OVER $1000, AND LASTED LESS THAN 20,000 MILES, AND ONLY 14 MONTHS OF DRIVING. NO SPARE TIRE OR JACK CAME WITH THE VAN, NOR IS THERE SPACE TO CARRY A SPARE, ALMOST FORCING ME TO BUY MORE RUN FLAT TIRES. FROM WHAT I'VE READ RECENTLY, TOYOTA MINIVANS ARE WEARING TIRES OUT MUCH SOONER THAN OTHER MAKES.

  The drivers side sliding door when on the power on, it will either not catch when opening or not shut when you are trying to shut it. You can be in the door way and it will shut on you by itself. You have to physically stop it or pull it shut. I have taken it in the past to the local Toyota dealership, when it was under warranty, multiple times. They don't see anything wrong, or cannot explain it but have replaced the sensor multiple times. It will be ok for a while and then start again. I sometimes wonder if cold weather affects it but there is no rhythm or reason to it. I am scared to have children or my parents use this door and if I turn off the power to it, it is very hard to use the door because it is so heavy. There are no warning lights, messages, or signals of any kind.

  SINCE 2004 TOYOTA HAS KNOWN THAT SIENNA AWD DAMAGE RUN-FLAT-TIRES (RFT) RAPIDLY AND NEVER REACH OR CLOSE TO 60,000 MILES OF THE LIFE OF TIRES WARRANTY. TOYOTA SHOULD FIX THIS PROBLEM THEN OR WARN THEIR CUSTOMER BEFORE THE PURCHASING (SEE THE ATTACHED DOCUMENT OF A CLASS ACTION). I PURCHASED SIENNA VAN AWD FROM L&S DEALER IN BECKLEY WV, THE SALESMAN NEVER TOLD ME ABOUT THE TIRES PROBLEM WILL BE WORN OUT COMPLETED WITHIN 30,000 MILES, BUT STATE THAT 60,000 MILES INCLUDED TIRES FOR ALL POWER TRAINED AFTER I NOTICED THAT THE VAN DO NOT HAVE SPARE TIRE. WHEN I BROUGHT VAN FOR TIRES WARRANTY FROM FIRESTONE CORPORATE SERVICE CENTER AND THEY TOLD ME THE SIENNA IS TOO HEAVY TO USE THIS TIRES. I HAVE TO PAY THE PARTIAL USAGE OF 60,000 MILES WARRANTY. THE BIG PROBLEM IS THE TIRES OF MY VAN CUPPED AND MAKING ROAMING NOISE WHEN ONLY 10,000 MILES WHICH MAKE DRIVING VERY UNCOMFORTABLE, DEFEATED THE PURPOSE WHAT I PAID FOR. THIS IS ABNORMAL FOR VAN OR ANY CAR THAT DAMAGES THE TIRES SO BADLY. THE OTHER PROBLEM IS THE VAN ACTS JERKING SOME TIMES WHEN I CHANGE LANE IN HIGHWAY. THIS IS VERY DANGEROUS. AT 29,000 MILES TOYOTA AUTHORIZED SERVICE CENTER TOLD ME THE TIRES CUPPED BADLY TO STEEL BELT, AFTER PARKED THE VAN FOR 1 MONTH I DECIDED TO PAY TO REPLACE TIRES (SEE ATTACHED PICTURE FOR THE CUPPED TIRES). I WOULD LIKE TOYOTA TO RESOLVE THE ISSUES -- REPAIR OR REPLACE THE EQUAL VALUE VAN BUT NOT AWD.

  Subject: Safety Defect Complaint – 2017 Toyota Sienna (VIN: [XXX] ) Dear NHTSA Safety Division, I am submitting a safety complaint regarding my 2017 Toyota Sienna, VIN [XXX] . In June 2023, while traveling on I-81 South in Virginia with my family of seven, the van stalled suddenly and emitted white smoke from under the hood, then the engine completely failed. The vehicle had only 111,000 miles. The repair would have cost $15,000, and I had to sell the van in 2024 for $4,000, suffering significant financial loss. Toyota informed me no recall applies to my VIN, although many 2017 Siennas experienced fuel pump failures causing stalling. As a person with disability and serious health issues, this incident caused extreme stress, hardship, and risk to my family. I request that NHTSA investigate this potential safety defect to determine whether other 2017 Siennas are affected. Sincerely, Your Name Phone Number Address INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

• 11/04/2025· UNKNOWN OR OTHER

  I am writing to report a significant safety issue with my vehicle involving a leaking sunroof that is causing damage to both the seatbelts and airbags. I believe this issue poses a serious safety concern and could lead to malfunctioning safety systems during an accident. I asked my local Toyota dealership for guidance adn they told me to clean the drain tubes out with weed eater wire. We tried that and the drains were working fine. If that did not work, it would be 3-5 thousand dollars to fix it. I have reported this issue to Toyota cooperate, but they are not willing to acknowledge the issue because of the year and miles on my van. There are several other Toyota Sienna van owner that have experienced the same problem and yet a recall has not been issued. This is my family vehicle that I drive my young kids around in. I feel that Toyota is willing to put my family's safety on the line by not acknowledging this on going issue. Issue: The sunroof in my vehicle has developed a leak over the past year that continues to get worse. The leak is allowing water to enter the cabin during rain. The water appears to be collecting around the area where the sunroof is installed and is dripping onto the headliner, seatbelts, and side airbags. It soaks my driver and passenger seatbelts for days. Damage: Over time, this leak has caused visible deterioration to the seatbelts, as they are getting wet and showing signs of wear. Additionally, the airbags may be at risk, as moisture could affect their proper deployment during an accident. I am concerned that the presence of moisture may result in these safety features malfunctioning when needed most. This could potentially be a fatal issue.

  At 70000 miles and around 9/1/2023, started to notice our brake stop suddenly steep down pedal when braking at 45mph or higher. Problem starts after fuel pump replacement recall completed by dealership August 2023. Check recall and campaign program, my vehicle VIN specifically not on the recall list for brake booster vacuum pump.

  I was driving and suddenly the 2017 Toyota Siena just lost all acceleration. The car no longer could move in gear. I put car into reverse or drive or any other gear and the vehicle would not move. The engine was on. The parking brake was not on. The transmission seems to have had a major malfunction. I had to have my car towed and my enitre family was stranded. I then looked up tranmission issues and found that 2017 Toyotas have a serious tranmission issue under “ Certain 2017 to 2018 Model Year Toyota Sienna Certain 2017 to 2018 Model Year Toyota Highlander Coverage for UA80 Transmission Customer Support Program ZJC”.

  While driving our vehicle on the highway, the check engine light suddenly came on and traction control turned off. Within moments, the vehicle began to stall and would not accelerate. My wife and children were in the car and we were nearly hit by another vehicle as she struggled to get the car to safety. It was a terrifying experience that put my entire family in danger, along with everyone else on the highway. Upon taking the car to the dealership, we were told the transmission failed and would need to be replaced.

The vehicle was taken to the local dealer who discovered that the plastic fuel lines were damaged due to the expanded anti corrosion coating applied to the fuel lines during manufacturing of the vehicle.

  On 10/14/2021, as my wife was pulling into our attached garage, the vehicle suddenly accelerated, hitting a metal storage shelf located at the back wall of the garage. The impact of the crash caused the vehicle and the shelf to extensively damage the dry wall of that area of the garage, as well as to damage the pedestal supporting the house water heater, which resulted in the water heater detaching away from the wall and being destroyed. There was, of course, also major damage to the front bumper area of the vehicle. It is my contention that the cause of the accident lies in some component of the vehicle acceleration system. I believe this to be true because of two prior incidents which occurred within the month before this happened. On 09/16/2021, I was driving this vehicle and wanted to make a U-turn. I was traveling at approximately 10 MPH, but as I began the turn, suddenly, the vehicle accelerated to about 25 MPH, even though my foot was off the accelerator. My wife and granddaughter were in the vehicle at the time and both expressed alarm, somehow thinking I had purposely made this maneuver, which I assured them that I had not. Then, approximately 7-10 days later (I am unsure of the date), I was driving, alone, in this vehicle and went to make a left-hand turn. The vehicle again accelerated, even though I had removed my foot from the accelerator pedal and was applying the brakes. I estimate that as I began the turn, my speed was 10-15 MPH, but the vehicle accelerated to 25-30 MPH. I dismissed both of these prior incidents as not too important and attributed them to some unknown anomaly on the road. However, after the latest incident involving the damage to my garage and vehicle, research showed that several Toyota models and specifically the Sienna have had similar issues in the past. I am reporting this incident to Toyota for their evaluation, but wanted to make your agency aware, also.

  On October 15, 2021 at 2 pm I drove into the driveway of a friend. I turned to the right of the driveway on her grass so I could backup and face the road. I’ve done this many times in the past. On this day as I put my foot on the break the van accelerated at a very very high speed. The van was out of my control at this point. I do not know how fast because this all happened in seconds. I was heading straight to their privacy wood fence only feet away. Approximately 20 feet. I don’t recall breaking again but turned the wheel to the right trying to avoid the fence. I hit the fence at a high speed damaged the left bumper and scraped the drivers side of the door. The next second I attempt to break again so I could back out of this when the van continued to accelerate at high speed going straight toward the house only a few feet away. I attempted to avoid the house and hit the right bumper hard at a high speed on the corner of the house. At this point the acceleration stopped and I was able to backup and turn the car around and finally turn the car off. There is major damage to the van and some to the fence and house. I was very upset and in shock and some soreness the next day but thankfully no one was hurt. This is a very small yard area that this took place at. I am still in shock and extremely confused as to why this happened. I do know without question my foot was not in the accelerator. The van is presently in the body shop. I would like to mention I have a clean record at the age of 64 I have never had an accident and/or speeding ticket in my life. This truly was not human error. I’m a very experienced driver. If it was human error the van should have stopped at the first point of impact on the fence, but did not. It continued to accelerate at a fast speed after hitting the fence hard. The van paused but continued to accelerate at this point when I hit the break again and it went toward the right straight for their house.

  While trying to accelerate on an onramp to the highway, the transmission failed to enter into higher gear, and the check engine light came on. The 2017 Sienna currently sits at 112,951 miles. Leading up to this, we had noticed the van jolting when being put into drive or reverse, and acceleration was often sluggish, with a whirring sound. Inspection by the local Toyota dealership found that the entire transmission needed to be replaced. The serial number of the transmission starts with UA02, which wasn't part of any of the existing 2017 Sienna service bulletins.

THIS IS USUALLY UPON STARTUP AFTER STOPPING AT A STOP SIGN OR LIGHT. BUT IT DID HAPPEN IN MAY OF 2019 AT 65MPH ON THE FREEWAY (GOING STRAIGHT), RESULTING IN SUDDEN DECELERATION. AS I MOVED OVER LANES TO GET TO THE SIDE OF THE ROAD, THERE WAS A SUDDEN JOLT AND THE CAR BEGAN FUNCTIONING NORMALLY. ON SUNDAY 9/22/19 AT 10AM I LEFT MY HOME WITH MY DAUGHTER TO GO TO THE MOVIES. LESS THAN 5 MINUTES FROM OUR HOME, IN OUR FLAT NEIGHBORHOOD GOING 25MPH, I STOPPED AT THE STOP SIGN THEN ATTEMPTED TO ACCELERATE THROUGH THE INTERSECTION. THE CAR WENT A FEW FEET INTO THE INTERSECTION AND THEN WOULDN'T MOVE, THE ENGINE MAKING A WHIRRING SOUND. IT WAS IN DRIVE. I TURNED ON THE HAZARD LIGHTS AND GENTLY ATTEMPTED TO PUSH THE GAS PEDDLE, FINALLY ABLE TO MOVE THROUGH THE INTERSECTION IN FITS AND STARTS (JOLTING) TO GET TO THE SIDE OF THE ROAD. I PUT THE CAR IN PARK, THEN NEUTRAL. PUSHED DOWN THE GAS IN NEUTRAL AND HEARD THE WHIRRING NOISE. IN DRIVE AND REVERSE, THE JOLTING CONTINUED. I WAS ABLE TO JOLT MY WAY HOME UNDER 10MPH. THE CAR WAS FINE WHEN IT WAS COASTING WITHOUT NEEDING POWER, JOLTING WHEN IT NEEDED POWER. BECAUSE THE CAR IS DANGEROUS, I HAD IT TOWED TO MAGNUSSEN'S TOYOTA, WHERE IT IS AS OF THIS WRITING. THIS IS A VERY DANGEROUS DEFECT AND NEEDS TO BE ADDRESSED AS IT SUDDEN DECELERATION IN AN INTERSECTION OR ON THE FREEWAY MAY RESULT IN DEATH.

  The fuel filler door assembly on this 2017 Toyota Sienna failed structurally due to a defective hinge mechanism. This defect directly compromises a critical vehicle safety system. The Sienna is engineered with a physical safety interlock cable that links the fuel door to the driver-side sliding passenger door. This system is designed to prevent the heavy power-sliding door from operating while the fuel cap is off, protecting occupants from injury and preventing the door from violently striking a gas station fuel pump nozzle during refueling. Because the fuel door assembly failed, the safety interlock mechanism was compromised, presenting an immediate risk of fuel pump damage, fuel spillage, or passenger injury from the sliding door. Toyota corporate previously issued a Customer Satisfaction Program (CSP) to address this specific structural defect. However, my local franchised Toyota dealership refused to preform comprehensive repair, claiming they "only cover the pin". This dealer non-compliance forced me to seek immediate out-of-pocket repairs at an adjoining facility to restore the vehicle's structural safety interlock system. Toyota Corporate is refusing to remediate this safety-related failure. I have made several attempts to resolve this directly with Toyota Corporate (6 or more), without success. This included several phone calls, and a letter written to the Toyota Brand Engagement Center, which went unanswered.

  Driver side sliding door stops and reopens when trying to close using power option previous van did the same thing but had a recall. When turning power door option off, it's stopped, doesn't want to budge much and you have to use all of your force to try to close it. This has being going on since 2018 when I bought it but there was no recall so delearship wouldn't touch it.

  When vehicle is park on an angle (with Front section lower than the back) power sliding door (behind front passenger) does not fully engages arresting hook and tends to immediately return to close position sometimes hitting passengers trying to enter or exit the vehicle. Vehicle was taken to dealer for check up but dealer claims to have been unable to replicate issue, possibly due to not placing vehicle on an angle. No warning lamps or lights indicate any issue with the vehicle passenger door(s).

  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.

  While traveling at a high speed, van's power train jerked hard and rapidly slowed on its own, not allowing me to excelerate. Almost rear ended by following vehicle that managed to swerve around to avoid my rapid deceleration. Check engine light came on and was hard to start. Had to allow the van to sit a while before I was able to start. Van acted like it was in limp mode. This malfunction has occurred several times. Mechanic code shows P0087 fault code. Low fuel pressure. Toyota has recalled many of these vehicles in this year for this issue, but mine seems to not be one of them. Very dangerous.
