Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I had first seen a check engine light for a month and it would come on and off and sometimes it would stay off for about a week before it comes back on and do the same thing. I had noticed some slippage within the transmission a week prior to this incident and was looking to take it in for an inspection but money is tight so I couldn’t afford to go in for an inspection, especially a repair. …”
