Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was just riding down the I-405 freeway near seattle, wa at about 70 MPH in the left with no shoulder available to pull over onto. The throttle suddenly failed and I had no power. I slowed dramatically and was nearly run over by a truck. I put on my flashers and moved 3 lanes right to get to the shoulder on the right. Traffic was heavy and I was fortunate not to be hit when I had no throttle control. I called a friend and he came about an hour later and towed me home. I feel that I was lucky not to have been hurt or killed in this incident.”
