Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The complaint I have is the inside front of the car is too small and I cant reach the gas pedal except with my toe. My foot keeps slipping off as I am driving. I have to have the seat way up or I cant reach. I am 5 foot tall woman. This is a ridiculous thing that I have to put up. I drove it for 10 minutes and didn't realize it. I asked for a pedal that is longer and closer to the floor after I had bought it and service people told me they don't have anything to do to fix it. They asked if I had a button to adjust it and I don't. Its on the expensive one. …”
