2021 Toyota RAV4

The driver’s seat adjustment mechanism failed and the seat became stuck, unable to move forward or backward. We initially went to a Toyota dealership and told them we believed the issue was a broken gear in the seat rail assembly. The dealership stated they needed to complete their own diagnostic assessment before proceeding, which would cost approximately $275 and add delay, despite already being told the likely cause. We instead took the vehicle to an independent mechanic, who confirmed the cause was a broken gear/synchronizing mechanism in the seat rail assembly. The mechanic confirmed that Toyota is the only source for this replacement part — it is not available from third-party or aftermarket suppliers — and has ordered the part directly from Toyota, at a cost of approximately $1,500, to install himself. This creates a safety risk because the driver is unable to adjust the seat position to reach the pedals and steering wheel properly, and cannot reposition the seat in the event of an emergency requiring rapid exit from the vehicle. Seating position also affects airbag deployment safety, since proper occupant positioning relative to the airbag is a factor in crash protection. There were no dashboard warning lights or error messages prior to the failure. The seat simply stopped moving on one side during normal, everyday adjustment. This appears to be a widespread and recurring issue rather than an isolated incident. Numerous other owners of 2019–2024 Toyota RAV4 vehicles have reported the identical failure — a broken gear in the seat rail mechanism — on Toyota owner forums and online community discussions, many describing the same high repair cost tied to the fact that only Toyota sells the necessary part. The vehicle is a 2021 Toyota RAV4 with approximately 56,000 miles at the time of failure. The component is available for inspection upon request.

The contact owns a 2021 Toyota Rav4. The contact stated that while driving at an undisclosed speed, the front driver’s seat became stuck. No warning lights were illuminated. The failure reoccurred on several occasions. The contact stated that water was leaking into the vehicle from the front driver’s and passenger sides, causing puddles of water in the front driver’s and passenger’s seats with an abnormal odor. The contact stated that the leak was near the bolts and screws. The failure reoccurred on several occasions. The vehicle was taken to an independent mechanic, who advised that the water leak could not be repaired and that the condition was unsafe. The vehicle was not repaired. The vehicle was taken to a dealer where it was diagnosed and determined that the A/C system and several other unknown components needed to be replaced. The dealer stated that the vehicle was out of warranty. The vehicle was repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

The driver side door actuator will not work, car is only five years old. Door will not unlock from fob, door unlock button or app. Began with a few random instances of not unlocking then turned into never unlocking again. Would have to climb through the passenger side to manually unlock by pushing switch. Got the actuator replaced but now car will not allow opening from inside, have to climb out of passenger door. This is a major safety concern as being unable to open a door in an emergency can be life threatening. The problem was reproduced and repair quoted by dealership. Problem was also reproduced by local mechanic and part replaced by them. Component inspected by manufacturer. The only warning was it sometimes not working, this began a few months back around February 2026.

My 2021 Toyota RAV4 began experiencing intermittent shuddering and vibration at low speeds around May 2026. The condition occurred while accelerating from a stop or at slow speeds and became more frequent over time. Because the problem was intermittent, the dealership was initially unable to duplicate it. Independent inspection later found dark transmission fluid containing metal debris, indicating internal transmission failure. I was informed the transmission requires replacement or rebuild. My vehicle has approximately 94,000 miles, which is well below the expected service life of a modern transmission. The symptoms are consistent with numerous reported complaints involving Toyota’s UA80 automatic transmission and torque converter. An unexpected loss of smooth power delivery or hesitation during acceleration creates a potential safety risk, particularly when entering traffic or crossing intersections. I am submitting this complaint so NHTSA can investigate as this is a very dangerous and concearning issue.

The sunroof exploded spontaneously while I was driving. It sounded like a gunshot. There were no other vehicles around, so it wasn't caused by a stray rock. It was only 73 degrees, so I don't think it was heat related.

I have been unable to get my vehicle inspected and repaired by a dealer despite months of waiting and asking two different Toyota dealers to order the necessary part or parts. This recall has been in place for years. For several years I was told it was only being done in certain states and that New Mexico would be last on list due to climate. Probably six months ago the message changed from Toyota and it was now ok in every state. Only problem is still no parts according to dealer. Last contact was on June 2, 2026 with the second dealer to order part. No call back and no contact. First effort was in Santa Fe NM where car was purchased new in 2021at Toyota dealer. Last effort over a month ago was at Albuquerque Larry Miller Toyota. So safety recall for faulty air bag sensor on my wife's side of car has been in place about 900 days without parts to fix a potentially deadly problem. VERY DANGEROUS
