2025 Toyota Sienna Owner Complaints

Headed seat barely warm

11/26/2024

The drivers mirror shakes every bump you hit so everything looks blury going above 30mph. This is a huge safety concern as you can't see cars clearly in the mirror. One of the second row seats also shakes considerably. I have brought it to the dealer multiple times and they will not fix it.

Driving roughly 60 mph on empty road with no cars in front. Sunroof was closed, and exploded with great force and 80% of the glass flew off. No objects impacted the sunroof prior to the sunroof exploding.

I bought this vehicle brand new. I quickly realized that both rollers on the sliding doors were causing excessive noise, which I found out that many other owners have complained as well, when closing & opening. This is because of a poor assembly from Toyota as the rollers are not machined prefect painted & are either oversprayed or less sprayed causing gaps on the rollers. These gaps or uneven paints causes excessive noise when rollers are moved on their track. There are several new Sienna owners who are waiting to have this issue fixed as the parts are backordered. I had to make total of 4 trips to my local dealership to have the issue fixed. I can still hear a little bit of over excessive noise from one of the sliding doors. Toyota should immediately recall all the affected vehicle and have this issue fixed.

Wobbling vibration on exterior mirror, driver side. It looks like incoming vehicles shake sideways. This happens on any bumpy road and it is easier to observe at highway speeds. Purchased on [XXX] Vehicle is available for inspection. The distorted image resulting from mirror wobbling affects driver's awareness of surroundings, visibility gets worse at nights/rain due to blurred lights. This can lead to an accident. My intuition when I first noticed was going to be a cold break but I realized that it was the mirror wobbling causing it. The car coming behind was far enough and I was able to react. Summary of actions and requests to Toyota: Two dealerships in central Texas have confirmed the issue but case was dismissed. Details below. 1. Dealership 1: Issue acknowledged by shop foreman , mirror changed but this did not fix the issue. Opened case with Toyota Brans Engagement and requested to work with a different dealership. This is the dealership where the car was purchased. Report wrongly stating rattled noise they weren't willing to correct it and pushed me to sign. 2. Dealership 2: Issue acknowledged again. Since mirror change did not fix issue shop foreman opened Dealer Product Request. 3. Current status: On 1/3/25 Toyota Brand Engagement advocate called to say that even though the shop foreman at the 1st and 2nd dealerships acknowledged the problem, the resolution was that it was a "normal" condition for the car. Case Reference #[XXX]. No warnings related to the problem. First occurrence: Day one, driving back from the dealership. Conditions were probably not met during test drive (you need to pay attention, more on that in the body of the post). Confirmation on day 2 on another drive, all with less 2 digit mileage, perhaps low 100s. Posting my case online has gotten 4 people reporting the same issue with cars since 2021 in multiple trims. Similar issue on RAV4 reported on [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driver side mirror visibly rattles when driving, but even worse when on highway. Safety concern is that visibility is blurred when driving. Vehicle is available for further inspection. Safety is put at risk since visibility becomes blurred when trying to change lanes. Yes concern has been reproduced, however I was told Toyota won't declare a warranty issue because other Sienna's and models of Toyotas have similar issue. Component has not been inspected by Toyota. However research I have done shows that Toyota is not acknowledging as a safety concern. No warnings. I purchased the 2025 Sienna Van February 8, 2025. I noticed almost immediately when I left the dealership, and turned back around for the dealership to inspect.

With the TV pulled down, there is absolutely no visibility though the rear view mirror even when adjusting the seat and mirror.

The driver side mirror vibrates at highway speed enough as to make it useless to observe cars behind you. Moving the mirror around does not help.

We were notified by Toyota that the second row seat rails had incomplete welds. Toyota recommended no one ride in the second row, and no child car seats should be installed in the second row. This greatly impacts the use and safety of the vehicle for our family of five. Additionally, the value of the vehicle has been impacted. Dealerships are not willing to give fair value for a trade-in because they know the vehicle will sit on their lot for an unknown amount of time before the repair is available. At this time (now 60+ days since the recall was announced), Toyota has not released the remedy and there is no timeline for the completion of these repairs.

See recall above. We just spent $55,000 on this vehicle in order to safely transport and travel with our two year old and newborn. The fact that Toyota does not have a remedy available for this major issue is completely unacceptable. The recall notice states that our only current "remedy" is to not use the second row seats, which is not feasible since child safety seats only safely install in the second row. This so called "remedy" is absolutely unreasonable, illogical and irrational. It essentially renders our $55,000 vehicle unusable, which constitutes a significant financial loss for my family. I am making a loss of use claim - Toyota's response that it does not have a remedy available now for such a significant safety problem is outrageous.

Drivers and passengers front doors make the sound as if they unlock and lock. The manual lock lever will flip as well however the doors will not unlock. This happens randomly both while trying to exit the vehicle and enter. When locked inside you have to crawl over the console to get to a door that functions . This is a major concern if you are in an accident and cannot exit the vehicle. Dealer look at my vehicle but could not duplicate it. I have a video of this when it happens

Purchased a **2025 Sienna XSE** with severe alignment issues since new. After **two failed repair attempts** at Fort Bend Toyota, the steering is now worse, and they damaged my wheel without offering solutions. This is a **safety hazard**—the car drifts dangerously at slow and highway speeds. The dealership dismissed my concerns, forcing me to escalate to **NHTSA** and **Toyota Corporate**. Avoid for serious mechanical issues—safety clearly isn’t their priority.

I bought this van brand new. I quickly realized that the reverse camera view has some issues. I believe images are not clean and sharp, as it is supposed to, and has unreasonable amount of distortions. Cleaning the camera from outside didn't do anything. I also noticed that the bottom part of center blue alignment line is little bit to the right and not align with the top. I checked online and it appears that other owners are also suffering from this same issue. Toyota should recall all affected vehicle and fixed this issue as soon as possible as this is a major safety issue when backing up!

Driver side passenger 2 nd row seat belt stopped working. Won't clip as needed leaving us unable to use seat. This is a safety issue as we are not able to use the seat as needed as one is not able to strap in. This triggers the sensor and this a driving violation. Problem has been reported. Vehicle has been reported and still pending to be replaced. Unkown when issue can be resolved. Passenger seat on the second row was stuck upon purchase. Dealer made aware. they claimed a sock was stuck on railing which was not possible as issue was reported before they could schedule for vehicle to be inspected. Such sock did not exist when incident was reported. Sock was not purchased until day before taking vehicle to schedule appointment. Tension is still there but agency said it is working properly.

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.

The contact owns a 2025 Toyota Sienna. The contact stated while driving 65 MPH, the sunroof glass shattered. There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The contact was informed that the VIN was not under recall. The manufacturer was not notified of the failure. The approximate failure mileage was 275.

The blind spot warning only shows the flashing light in the side mirror but does not make an audible warning sound.
