What 2024 Toyota Sienna Hybrid owners say
Brakes
The contact owned a 2024 Toyota Sienna Hybrid. The contact stated while driving at an undisclosed speed, the brake pedal was depressed, however, the vehicle failed to stop as intended. No warning lights were illuminated. The contact stated the vehicle was unstoppable. The contact stated the option was to crash into the three vehicles which were coming from the opposite direction or to crash into the pole to bring the vehicle to a stop and avoid injuring pedestrians. The paramedics and the Police department arrived at the scene of the crash. The contact's wife, who was the occupant of the front passenger's seat, was transported to the local hospital. The contact sustained bruises and an open wound which was continuing to heal. The contact's wife sustained bruises and bumps. The vehicle was towed to a local tow yard. The vehicle was condemned as a total loss. A police report was filed. …
Three (3) separate systems failed. 1. Upon seeing cars ahead of us slowing down, my husband pressed the breaks to slow down to avoid collision. When he pressed on the breaks, instead of slowing down or stopping the vehicle, the brakes failed to engage, and caused a surge that compelled the vehicle to lurch forward. The lurch propelled our vehicle into collision with another vehicle. 2. Also, the forward collision warning system failed to alert or engage the breaks. Our vehicle was stopped by the impact of hitting the other vehicle, not by its own breaks. 3. The automatic breaking system also failed to engage at all prior to impact.
Speed control & acceleration
Vehicle was driving on a slow traffic local street at roughly 10MPH. Spacing between car in front of me was around 30 ft. I was gliding towards front and ready to brake. Suddenly the vehicle start to accelerate hard by itself without driver's operation. I tried to engage brake / gas pedal and was not helping. Front collision system did not activate like it suppose to. I ended up turn sharp right towards road curb and hit pole at average speed of 30mph or less. No air bag deployed. I then switch to Park. No warning lights pop up. All safety features on vehicles were turned on before the incident. Whats weird is the car is functioning normal now after incident. I contacted Toyota USA and waiting for feedback.
While driving on highway, on 3/11/26, car powered down. I had to coast to side of highway. I was able to turn vehicle on after several minutes, but SEVERAL system malfunction error messages (hybrid, accelerator, pre-collision, tpms, airbag, engine...) appeared. The vehicle would not accelerate beyond 10mph. Once I moved it to a safe location, I had the vehicle towed to the dealership. The dealership technician was able to replicate the issue during test drive. The technician apparently had the vehicle towed back to the dealership last night. The car has had other related issues since June 2024 when I bought it. The TPMS system, the accelerator system, and the airbag system have all malfunctioned independently. The accelerator system malfunctioned in Jan. I had to pay for a replacement fuse despite the warranty. The vehicle is modified with Braunability equipment for wheelchair access. …
