Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The spare tire hoist cable system tangled or jammed and would not allow the spare to lower further or raise. I had to use rope to tie the spare tire to the frame to make sure it would not fall down while I was driving which clearly could have thrown the back of the vehicle upward. The dealer had to cut the cable and replace the entire hoist assembly: $176.54. The hoist had been used successfully on three other occasions.”
