Known Problems

The Check Engine Light may illuminate due to a defective charcoal canister vent control valve. The charcoal canister is a component in the Evaporative emissions (EVAP) system.  Our technicians tell us a failed vent valve will require replacement.

Worn door locks (tumblers) can cause the lock not to work. Removing the lock and replacing the worn parts (tumblers) is needed to get the lock working again.

If the transmission oil leaks out of left side half shaft area, it may be from a worn axle shaft seal. The seal can be damaged by a poor surface finish on the axle shaft. The axle shaft and seal should be replaced to correct the problem.

Various issues with the electric power steering system may develop and could require replacement of steering column assembly.

The engine may not crank when the key is turned to "start" if the starter relay fails. This can be confused with a defective starter motor.

Occasionally, the anti-lock brake (ABS) warning light may illuminate. This could be due to a faulty rear wheel speed sensor. The sensor design has been updated and revised parts are available to correct this problem.


The service 4WD system light may illuminate with no fault codes stored in the final drive control module (FDCM). Our technicians tell us a software update for the FDCM is available to correct this concern.

In order to correct a problem that results in difficulty starting, engine vibration, or a rattling sound from the engine compartment, Kia released an updated crankshaft pulley bolt.

A clicking type noise may be noted from the rear of the vehicle while driving. Our technicians tell us that revised rear coil springs are available which may correct this concern.

Intermittent rough idle may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open. Our technicians tell us the valve and sensor must be replaced together to correct this concern.

One or more power windows may fail. Our technicians tell us this is commonly due to a failed window regulator which will require replacement.

Toyota released a software update to fix a problem that caused the Check Engine Light to come on. Before the update, the computer would report a problem with the catalytic converter when there wasn't one.

A cosmetic crack may develop on the plastic liftgate trim panel. Ford has released a service procedure to replace the applique without damage the the liftgate glass.

Replace the worn wheel bearings.

The wiring for the transfer case speed sensor can fail causing sporadic operation of the AWD (All Wheel Drive) system.

Various problems with the 5-speed automatic transmission were common. These problems can be more common on the 2002 models with build dates before March, 2002. There are many service bulletins describing the diagnoses and repairs, which include fluid leak repairs, transmission software updates, or internal failures requiring a costly repair.

If the heater is on and no heat is felt from the right side dash vents, there may be a problem with the blend air door shaft; a revised part is available to address this concern.

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

Illumination of the Check Engine Light may be the result of a loose or worn gas cap.

The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.

Ignition coil failure may cause the engine to run poorly. The fault can be intermittent and may or may not illuminate the Check Engine Light.

Sensor failure inside the distributor can cause intermittent stalling or a failure to start. In addition, the wires to the distributor are susceptible to internal damage, which can cause the same symptoms.

Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

The AC evaporator drain commonly clogs and causes water to leak onto the passenger side floor. A sloshing noise may also be heard from the water inside the heater housing. Decaying organic debris in the housing may cause an odor. A service bulletin (TSB 24-06-96) was released; it describes how to clean the drain tube without removing the heater AC housing.

The electrical connector at the automatic transmission may leak fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. At that point, a new harness and control module may be necessary to correct this problem.
