Known Problems

The tachometer sensor may fail; if the tachometer needle jumps around and the transmission has harsh shifts or does not upshift, this sensor should be checked. This sensor is mounted in a cover at the front of the motor.

Nissan issued a recall on the fuel pump for premature failure. There was an owner notification program and labels were placed on the fuel pump access panel and next to the AC charge label in the engine compartment.

The airbag warning light (SRS) may illuminate due to a defective occupant position sensor. Honda has a recall campaign to replace defective sensors on affected cars.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

Brake lamp housings can melt, resulting in a loss of contact for the brake light bulb holder. If this happens, the brake light will not work. Replacement of the damaged lamp housing should correct this problem.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

Difficulty starting the vehicle may be caused by a defective vehicle immobilizer (anti-theft) control module.

The instrument panel and switch backlighting may fail due to a faulty dimmer control module. A failed module will require replacement.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

Long cranking times in cold temperatures (below freezing) may be solved with a software update to the Cummins ECM.

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

If the engine cranks but won't start, the fault may be internal to the distributor. Diagnosis will show no spark and trouble codes for the crankshaft position sensor (CKP) or the camshaft position sensor (CMP). Our technicians recommend replacement of the complete distributor assembly if these conditions occur.

The front oxygen (air fuel ratio) sensor element may develop a crack, causing the Check Engine Light to illuminate. Subaru has recalled certain models to replace sensors that may fail. The Subaru service program number is WXW-80, this is not a government mandated recall.

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

Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.

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

Vehicles with a V6 engine may develop an oil leak from the front crankshaft seal. Our technicians tell us a revised front crankshaft seal is available to correct this concern.

Poor fitment of the headliner, which may or may not develop into a rattle noise around the sunroof area is generally caused buy foam isolation blocks becoming detached from the headliner. The repair involves re-securing the foam blocks using cable (zip) ties.

One or more of the power door locks may become inoperative. Our technicians tell us that modifications to the door hardware and door panel may be necessary to correct this issue.


The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2001-2003 models is #4114K (trade number).

The engine may overheat at idle when the AC is on. A new, upgraded fan motor and resistor assembly should be installed.

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

Poor quality low speed transmission shifting may be noted. Our technicians tell us updated transmission software is available which may correct this concern.

The idle air control motors tend to become carboned up at around 100,000 miles and can cause a start and stall and/or stalling at stop sign problems. Our technicians tell us that many times these motors can be cleaned, however, the sure bet is to replace the idle air control motor and clean the throttle body.

If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.

The distributor shaft bearing can become rusty, and seize causing the engine to stall or not start. The failed distributor will commonly require replacement.
