POWER TRAIN
My Toyota sienna is a 2020, has 83,000 miles and has recently been squealing when I accelerate. I took the van to a local body shop and they said it seems to be my transmission. I called Toyota immediately and they knew that the transmissions were faulty and that they would try to work with Toyota to get it fixed. There is no way I can pay 9k for a new transmissions because they put in faulty ones.

We were notified by Toyota that it was unsafe to transport our children in the second row seats in November 2025 and the vehicle was under a recall. This puts our children at risk such that we cannot use the vehicle for its intended purpose, namely, transporting our three young children. A letter from NHTSA stated Toyota would have a remedy by 12/6. The manufacturer (Toyota) confirmed this recall. Given that Toyota has not indicated a solution date for this and the problem was discovered in October 2025 I believe the manufacturer has failed or is unable to remedy this safety recall for our vehicle in a timely manner and would like to officially log a complaint with NHTSA

I am filing a formal complaint regarding my brand‑new 2025 Toyota Sienna, purchased in February 2025 for nearly $70,000. I am still paying interest on this vehicle, which has failed to perform as promised. From early ownership, the vehicle had issues including multimedia malfunctions and unsafe lane‑change behavior on rough roads. In October 2025, Toyota issued a recall for faulty second‑row seats due to improper welding, creating serious safety concerns. This recall has effectively defeated the purpose of purchasing the vehicle. The Sienna was bought as a seven‑seater, but due to the recall it functions as a four‑seater, making it impractical and unsafe for my family. Daily use now causes: Increased back pain from bending to seat and secure children Children kneeling to access the third row, causing pain and injury risk Risk of dropping a child, slipping in rain/snow/ice, or being struck by passing vehicles when exiting backward Significant difficulty for an elderly parent with back pain Ongoing fear that the recalled seats could fail in an accident and injure occupants I contacted Legends Toyota (Kansas City 66109) and Toyota headquarters. The dealership offered unsuitable replacements, including a smaller vehicle or one recently repaired for other issues. Toyota corporate has provided no meaningful remedy, only loaner vehicles that are not equivalent to what I purchased. I believe this represents serious consumer harm: Toyota collected a large sum for a vehicle that cannot be safely or reasonably used and has failed to resolve a known safety defect while continuing to sell newer models without guarantees. I respectfully request an investigation and a fair remedy, such as a refund or equivalent replacement. Thank you for your attention to this matter.

The vehicle is a 2025 Toyota Sienna Hybrid subject to a safety recall related to the rear seating area (third row). We were informed by the manufacturer and dealership that no remedy is currently available and that the vehicle may be unsafe to operate as intended. The concern involves potential safety risks with the rear seating system, which affects safe passenger use, especially for family transportation. As a result, we have limited use of the vehicle and do not transport our children in it due to safety concerns. While the vehicle is still occasionally driven, it cannot be safely used for its intended family purpose. The issue has not been resolved, and we have not received a loaner vehicle or alternative transportation despite multiple attempts through the dealership and manufacturer escalation channels. No repair has been performed, and the issue remains open under recall status.

VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR
The driver's side mirror vibrates when the vehicle is at speed. I've been to two dealers who say that it's normal, and everything is intact and installed correctly. When driving, the mirror vibrates a lot, which is a safety issue when trying to use the side mirror during changes, etc.

The drivers rear seat on toyota sienna minivans has play in it. My concern is that when you install a car seat tight, the seat has play and can loosen. I can send a video. Picture won't help. It appears to be a common issue with these.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
The vehicle is a 2020 Toyota Sienna. While driving, the engine suddenly shut off without warning, creating a dangerous situation and loss of power. This occurred while transporting children, increasing the safety risk. A mechanic inspected the vehicle and diagnosed a failure of the low-pressure fuel pump. The problem appears intermittently — sometimes the vehicle runs normally, and other times it stalls or loses power. The check engine light has turned on and off. This issue matches the known defect related to the Denso fuel pump recall affecting many Toyota vehicles from similar model years. However, my VIN is not included in the recall. This is a serious safety concern because the engine can shut off unexpectedly while driving, which could lead to an accident. I believe this vehicle may have the same defective component as those included in the recall, even though it is not currently listed. The issue has been confirmed by an independent mechanic and the vehicle is available for inspection if needed.

No specific incident occurred. This recall has been active for almost 7 months. I am uncomfortable putting my newborn in the middle rows of seats that are affected and my wife has a medical condition where putting our newborn in the back row is difficult. We are only using our other vehicle at this time until the recall is fixed. 7 months without remedy is unacceptable.

[XXX] [XXX] / [XXX] [XXX] 2010 Toyota Sienna Possible Shifter Interlock Failure: On [XXX] my [XXX] child found his way into the driver’s seat of our 2010 Toyota Sienna while the vehicle was parked in the driveway. According to my wife, there were no keys in the vehicle, and the vehicle was in park. In an instant, my wife (who was outside the van) helplessly observed the van begin to roll backward down the driveway and then across the sidewalk (on our side of the street), then across the street, and then across the sidewalk on the other side of the street and into the neighbor’s yard where it finally came to a rest. She said she heard something like grinding gears. I presume my son was trying to put it in park. Thankfully no property damage or personal injuries occurred during the incident. I [XXX] ) was not home when this happened. When I returned home, I inspected the van to see if my son was able activate the emergency shift lock release. I found the cover was intact and evidence of tampering was not observed. I then checked to see if I was able to pull the shifter out of park. Initially, I was unable to, but after a few tries and a little force, I was able to pull the shifter out of park (no keys in ignition, no brake compression, vehicle off) and the van began to roll. Our driveway is somewhat sloped. I replicated this procedure several times: a little force and a little wiggle and clunk, the shifter released and the van rolled. I discovered there was a recall for this very problem on 2010 Sienna’s (NHTSA Recall No.: 17V-657). I entered the Sienna’s VIN number on NHTSA’s website and found no active recall for the VIN number entered. I contacted Toyota of North America (1-800-331-4331) and chose to advocate and spoke to an agent and reported the problem. She was able to determine that the vehicle had been under the recall, but the van was “repaired” in 2020 which is the year we bought the van INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
