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.

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.

UNKNOWN OR OTHER, STRUCTURE:BODY
Dear Sir/Madam, I am writing to formally raise a complaint regarding a serious and ongoing issue with my 2024 Toyota Sienna XLE AWD, purchased in April 2024 in Illinois. From the very first day, the trunk door has not functioned properly — often failing to close, randomly opening, or requiring manual force to shut. Despite repeated service visits across multiple states (IL, SC, NC) and investing considerable time, fuel, and lost income as a contractor, this issue persisted for over 18 months, creating safety concerns and inconvenience for me and my family. Key Issues: Trunk door opens on its own – even while reversing, creating serious safety risks. Malfunctioning power close mechanism, requiring manual closure frequently. Unreliable performance: door would close, then immediately re-open. Visited Toyota service centers at least 6 times across 3 states. Each visit took 2–3 hours, costing me work hours as a contractor. Customer service experience has been poor, especially with manager Patte, who: Failed to schedule proper service appointments. Directed me without coordination. Refused to escalate my request or connect me to her manager. Dismissed my request for compensation by saying, “It’s your issue.” Please help me on this issue. Thanks in advance.

POWER TRAIN
The contact owns a 2017 Toyota Sienna. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the vehicle briefly hesitated before shifting hard into gear. The contact stated that after the failure, there was an abnormal whining sound coming from underneath the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who was unable to provide a specific diagnosis for the cause of the failure; however, the contact was informed that there were known issues with the transmission of similar vehicles. The vehicle was not repaired. After investigating the failure, the contact related the failure to the Customer Support Program Bulletin: ZJC. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 40,000.

STRUCTURE:BODY
The power sliding door assembly failed, and the driver side rear sliding door was bound shut, and could not be opened. Disabling the power door system did not resolve the issue. The cable for the power door mechanism was hanging below the rear vent windows; but for some reason the door still would not open. I ultimately with a lot of gentle force was able to get the door open enough to see the retract side of the cable was bound up, and was able to cut it with wire cutters, and ultimately get the door to work normally as a non-powered manual sliding door. Since the original NHTSA BULLITIN on this was published in 6/2019 before my 2020 Sienna was manufactured, and Toyota did not change the mechanism until the 2021 model redesign, I believe that RECALL should be extend to all 2019 and 2020 vehicles. This seems dangerous that the door does not default to manual operation in error.

After very minor rainfall, my rear backup camera was not usable as water was dripping off of the edge of the door handle trim and it was getting on the lens. This is a complete design problem as there should be a drip edge. You made it very difficult to properly pull up at a gas station pump and I was unable to get close to the pump because of how the lens was obscured by the water drops.

SEATS
When a lever is pulled, the second row seat can move freely back and forth on a track until the back of the seat is returned to the upright position. I was driving at highway speeds and had to brake suddenly. The seat was at the back of the track with the lever pulled, and it slammed into the back of the driver seat, hurting my back. It stuck there putting pressure on the seat (which could be felt) until I stopped and had to use force to make it slide back.

VISIBILITY/WIPER
Outer rear-view mirror on the driver side exhibits a vibration/shaking of the image. It is obvious and continuous vibration is observed typically on highway speeds of approximately 60mph or higher and lower speeds it is evident driving over slight bumps, concrete/asphalt road surfaces or bridges. Looking at the shaking image cause dizziness and it is even worse in night time with headlights from vehicles coming behind. It is annoyance to the point that makes you feel not to use the rear-view which can potentially put the vehicle and others in danger. Passenger side doesn't vibrate and makes it easy to notice the issue. Dealer inspected the mirror and said manufacturing issue and replaced it under warranty with no success is fixing underlying vibration issue. On the second visit, dealer denies the problem and says the mirror is replaced and operates according to toyota specification (it feels to us they do not care about the functionality). According to dealer they will do anything further only if Toyota release a TSB on this particular issue.

VISIBILITY/WIPER
The drivers side exterior mirror shakes. This occurs during all driving, most notably over bumpy roads and at highway speeds. The passenger side mirror does not have this problem. Because of the shaking, it is distracting when driving as it appears there is movement in the mirror. Additionally, it causes a distortion from the constant movement. The vehicle was purchased in June 2025 and has occurred since day 1. The vehicle was in the dealer on 9/30/25 and noted the issue, stating there is nothing physically wrong with the mirror but did agree with the assessment. They said this is common on vehicles (they see the complaint a lot) but Toyota has not acknowledged it so there is no fix and appears to be a manufacturing defect.

SERVICE BRAKES
When i am driving from high speed and trying to use my brakes, the whole rear car will start shaking around 48/45 miles per hour , I can hear our car seat from our baby how it makes vibrating noises and i can see my both door mirrors they're shaking too, and when it drops to 40mil per hour the shaking goes away. Went to the local Toyota dealer 3 times and they're saying that's normal. Very disappointed with a brand new car. We have another new car and doesn't do that for sure... Called Toyota national, open a case and they're saying, mechanic can't find anything wrong. They should drive this car for a longer distance and they will know for sure what I am talking about.
