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. The tank had to be sent out for welding. Of course, I had to pay for the repair even though I spoke directly to the Mitsubishi complaint department. Since it was not a recall item, Mitsubishi or the dealer will not pay for the repair. The dangerous fuel leak is another ongoing hidden problem. Alternator pulley: Has been making noise from the beginning and I have complained each service. Now, I discover through NHTSA that alternator pulley is a known design flaw. Mitsubishi and their dealers must be held accountable.

When exiting vehicle driver's side automatic shoulder belt does not retract. Consumer contacted dealer, dealer adjusted the belts, problem still occur. The brakes make noise due to front pads wear and front brake rotors warping. The transmission shutters occasinaly when taking off and was replaced with new one.

Transmission has been replaced during repairs, and the vehicle sometimes revvs high and then dies out. Also, it is sometimes very hard to stop the vehicle, . the dealers cannot duplicate the problem.
