Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Safety - transmission: at 9,500 miles my car started lurching when stepping on the gas from a stop. It supposedly was repaired but has continued to be problem and each time I bring it in for service the dealer can not recreate the problem. Since I had not heard that this has been on going problem with this model, I thought it must be something that I had done. Upon reviewing the information of nhsta, I realize that the dealers and Mitsubishi are deliberately hiding this problem. Safety - fuel tank: my fuel tank began leaking at 59,560 miles and when the dealer removed it had 3 stress wholes. …”
