Ill be brief I own the above car and have a safety problem that is not being fixed by Mitsubishi. With about < tank of gas in the car, a hard right turn or exit off the expressways, causes the car to completely stall no power steering, brakes, no acceleration. Worse, this is a problem with all Diamantes (verbal via the service rep for the chicago area jeff hampton). I have been in a situation more than once where this has almost produced a rear end accident by semi trucks and other vehicles. Mitsubishi says this is an engineering issue and they dont know what to do (note this has been going on since July 2000), since a new tank or fuel pump would not fix the problem. Even the 2002s are going to have this problem.
