Example complaints

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

“The latch on the back door melts when the weather is hot, leaving a black, tarry mess in my hands. Now that the weather is cold, the latch on the back door is frozen solid, making it extremely difficult to open the back door at all. This could be dangerous if I need to open it quickly. The van is, of course stationary when I try to open the door. The dashboard also melts in the heat.”

“My wife and daughter were traveling on our 2010 Sienna on 07/11/2015 (sat) and the gears seized up when they were turning into a busy 4-lane road. In spite of complete loss of transmission, due to the sheer momentum of the vehicle, my wife was able to direct the vehicle to the right side of the road. When she called me, I arrived to see my daughter crying and standing on the side while my wife was trying to push the van further right with the help of an old couple who were extremely helpful. …”

“While trying to park my 2010 Toyota Sienna with one foot on the brake the vehicle accelerated into a sign post and into the vacuum at the car wash. The vehicle's brakes went soft and unresponsive even with both feet on the pedal, it only stopped when it could not go any further and I was able to put the vehicle in neutral. There was damage to the driver side front quarter panel as well as property damage. I simply could not stop the vehicle.”
