One problem related to tank assembly has been reported for the 1997 Mitsubishi Galant. The most recently reported issues are listed below.
The brakes and steering wheel shake when the brakes are applied. The brakes seem to make a popping noise when making a left or right hand turn. I have to apply brakes at a far distance to prevent from running into other vehicles. The problem has existed for awhile and noted to service dealership on numerous occasions. In addition, noise can be heard from the gas tank when braking. You can hear the gas shaking from in the tank. This is a concern when transporting passengers in the rear compartment. Don't know if the tank will eventually explode or ignite a fire.
