Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“multiple times this has been an issue. I stepped on the break and the car essentially leaps forward typically when going up down or straight. In November 2024 it happened while going up a hill slowly and I bumped into the vehicle ahead of me. My vehicle had no damage, but the car in front of me had to get a new skid plate and my insurance doubled because of it. Since the incident in November 2024, my car has unintentionally accelerated intermittently. …”
NHTSA complaint #11660961, filed 2025-05“The vehicle has a standard installation of a kick sensor for the rear hatch. I purchased the vehicle used and was able to start the vehicle and drive it for a period of time hoping to charge up the 12V battery. However, upon stopping the vehicle I could not restart it. Even after repeated jumpstart and driving the vehicle for over 45 minutes, the 12 V battery could not restart the car. I read about a similar issue with 2022 Toyota vehicles and so I followed the directions to disable the kick sensor. …”
NHTSA complaint #11639214, filed 2025-01“On July 7, 2023 I paid in full and was given possession of the 7 passenger seating Toyota van. The car has automatic door locking mechanism as part of the electrical system and can be locked from inside the car. The van is used to transport 2 children in car seats who can touch car components. We were given one Keyfob by the dealership and we were told that Toyota manufacturer did not have a second Keyfob to give at that time; we were told that we would get the second Keyfob within a few weeks. …”
NHTSA complaint #11546748, filed 2023-09“The contact owns a 2023 Toyota Sienna Hybrid. The contact stated while driving and depressing the brake pedal to come to a stop, the vehicle jolted. The vehicle was taken to the dealer, where the contact was informed that the vehicle was operating as designed. Additionally, the contact stated that upon starting the vehicle, the messages Parking Brake Malfunction , Parking Brake Unavailable and Door Ajar were displayed. The gear shift indicator light and the parking brake warning light were illuminated. …”
NHTSA complaint #11669159, filed 2025-06, 44,242 miles“Passenger side sliding door randomly opens even when car is in the locked mode and when parked. It has happened 4 times. Toyota blames my chair lift and the mobility works blames Toyota. Service has not been able to recreate the problem since it is intermittent and has documented the complaint. However the only way to insure it doesn’t happen is to shut off the power to the doors making them difficult to open. This has only happened while parked but is a safety issue when not at home in the garage.”
