“My 2024 toyota sienna suddenly stopped for 2-3 seconds while driving in the city roads. I was caught off-guard with that behavior. I kept pushing on my gas pedal and after few hard pumps the power came back. This happened couple of times so far. Not sure what the main problem is.”

NHTSA complaint #11717553, filed 2026-02

“Hello, leader. I bought my car (Sena Platinum Edition) for three months. Due to a mistake in the appearance, I need to replace the engine now. My new car will definitely depreciate if the engine is replaced, so I hope Toyota headquarters can refund me in full. I need to buy a new Sena! My house is full of Toyota cars, no matter what the result of Toyota Company's handling? I will still choose to buy a Toyota! Thank you!”

“I was at a complete stop. There were no obstacles around me or oncoming. When I pressed the accelerator nothing happened for a full 3 seconds, until my vehicle jolted forward at an excessive speed. Brakes were not working.”

NHTSA complaint #11592492, filed 2024-06

“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 contact owns a 2024 Toyota Sienna. While the contact’s wife was driving 5 MPH out of a parking lot and attempting to make a left turn, the vehicle suddenly lost motive power and stalled. After approximately 3- 4 seconds while depressing the accelerator pedal several times, the vehicle eventually accelerated as needed. The vehicle was driven to the residence. There were no warning lights illuminated. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 68,000.”
