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.*AK
THERE IS A VERY DISTINCT GAS SMELL IN AND AROUND THE CAR. IT ALSO LEAKS GAS FROM THE GAS TANK WHEN FULL. I HAVE NOTIFIED MISUBISHI SEVERAL TIMES AND I HAVE BEEN TOLD THAT MY CAR IS FINE.
