Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was driving 65 MPH on the highway going straight on dry pavement and suddenly a buzzer sounded, the vsc light came on, and the steering wheel and brakes were taken over by the vsc system and the car started weaving out of control. I could not steer or break the car. The situation is unpredictable. It easily happened on curvy or bend road and has happened 3-4 times in this year. It is scary.”

“I was driving my Toyota Sienna 2006 today morning and the driver in front of me abruptly stopped. I was maintaining a safe distance and immediately hit my brakes. Although the brakes seemed to engage, the car accelerated and very badly rear-ended the car in front me. Has this happened to anyone before with the car auto-accelerating on it's own?”

“Two episodes of sudden unexplainable acceleration. 2006 Toyota Sienna mini-van. First incident: driving at about 25 or 30 MPH. Car suddenly sped up. Using brake stopped the car. Second incident occurred when I put car in reverse to back into my driveway; sudden speed increase in reverse. Brake worked to stop.”

“Toyota Sienna 2006 braking problem caused self collision. On dry weather. Vehicle lost braking and I hit near by hilly land on turn. Vehicle showed braking problem on wet weather, rain and snow and vehicle looses the braking and related ABS and vsc failure. Brake pedal goes down and clicks and brake stops working. My wife no longer trust this van and everybody is afraid to drive with me in it.”

“We bought a 2006 Toyota Sienna van brand new from a local dealer. Almost from the beginning the rpms would increase without provocation. I initially thought it was a problem with the transmission and had it checked but it turned out okay. I then thought it was maybe a problem with the fuel line so I had it flushed but the problem persists. It happens off and on and usually when I am driving along. …”
