Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Looked online to see if other Sienna drivers had the same issue with the hybrid system. Brakes are accelerating a bit even when already pressing on the brakes. It has happened enough times to be concerning. We have not taken it to the dealearship as of yet but will be getting in touch soon , now that we know it's a known issue. No warnings from vehicle.”
NHTSA complaint #11694919, filed 2025-10“When I am rolling to a stop, or lightly pressing in the brakes, the car will occasionally jolt forward and I have to slam on the brakes. It is not every time but has happened many times since buying the car new. I brought it into the dealership and they could not replicate it, but it makes me so scared to drive. This could result in an accident or the hitting of a pedestrian. No warning lights.”
NHTSA complaint #11656862, filed 2025-04“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“Stepping on brakes - Car slows then accelerates a few seconds and lunges forward a couple of feet. Extreme safety issue. This occurred yesterday with my sister in the car and we almost rear ended the vehicle stopped in front of us. I have complained to the Cumberland Toyota dealership in the past and was told if they cant recreate the issue and it doesn't happen all the time there is no way to fix the issue. Yesterday I was almost in an accident because of this faulty design/anomaly associated with my car. …”
NHTSA complaint #11738078, filed 2026-05“Moving about 55 miles per hour on right lane of I-95 the Jeep in front of me braked abruptly. I braked hard but as my Sienna was quickly slowing down to stop, the brake pad felt spongy when it was slower and as I pressed even harder, it seemed to have stopped decelerating at that slower speed and that was when my Sienna slammed into the back of the Jeep. Happened today on July 15, 2026 at around 4:24 EST. I will also file this same report to Toyota. My wife and I are at the hospital getting checked, but my Sienna looked undrivable.”
