Known Problems

The sunroof may become stuck in the closed position or require "help" moving forward and backward. The common repair is to replace the guides but often the problem will resurface again.

One or both side airbag modules may fail resulting in illumination of the airbag warning light. Side airbag modules determined to be faulty should be replaced.

A rattle noise may be noted from the clutch area while the car is at idle. If the noise changes or goes away when the clutch is depressed the fault is commonly with the clutch disc springs. It has be reported that a revised clutch disc is available from Mitsubishi to correct this concern.

 

The clutch may fail prematurely or cause a buzzing type noise from the dash area. It has been recommended by some that a high quality aftermarket replacement clutch may provide increased longevity over a clutch purchased from the dealer.

The front, lower ball joint may fail unexpectedly resulting in loss of vehicle control. Failed ball joints will require replacement. Our technicians recommend a complete inspection of related suspension components if this situation occurs. This should be done in order to determine if there is any other damage as a result of the ball joint failure.

The manual transmission may become difficult to shift, this is commonly caused by binding between the synchronizer and the gear surface. Adding a special friction modifier to the manual transmission fluid will often correct this condition. If the problem persists revised synchronizer kits may be available.

The Check Engine Light may illuminate with no fault confirmed. Our technicians tell us a powertrain control module (PCM) software update is available which may correct this concern.

The Check Engine Light may illuminate due to one or more engine vacuum leaks. Our technicians tell us these leaks can be caused by damage to seals and/or vacuum hoses as a result of to much ethanol content in the gasoline. Affected hoses and seals must be replaced to correct this concern.

The door glass may be hard to roll up and/or come out of the run channel. Our technicians tell us the repair can include adjustment of the run channel, regulator to glass, regulator to door, and if necessary shimming of the window regulator.

The brake pedal may pulsate when the brakes are applied. This is most commonly caused by the front brake rotors warping. Resurfacing the affected rotors may correct the problem for the short term but replacement would generally considered a longer term solution.

Excessive clutch vibration may be noted starting from a stop. This can be a result of a warped flywheel or a faulty clutch pressure plate. Our technicians recommend removing the transmission, inspecting the clutch and repairing or replacing worn or damaged parts as necessary.

 

A squeal or squeak type noise may be heard from the rear brakes on application. Our technicians tell us there is an updated rear brake pad shim kit which can help reduce this type of noise.

On 2.4L 4 cylinder engines a whining noise may be noted when the engine is cold and the rpm is in the 1800-2000 range. Our technicians tell us that most commonly this type of noise is coming from the engine oil pump. The repair is to replace the front case assembly and both the drive and driven oil pump gears.

Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.

The engine may stall or develop a rough idle with the Check Engine Light illuminated and fault code 15 stored in the ECU. Our technicians tell us that the engine electrical grounds are critical, all 5 should be inspected and cleaned as necessary. An additional ground lead kit is also available which can be installed to help correct this condition.
