Known Problems

The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.

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.

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 AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

Due to the design of the reverse gear system in the AX-15 manual transmission, it may block shifting into reverse one out of every ten attempts. An updated reverse gear is available if the concern becomes more frequent.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.

A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.

The outer exhaust manifold studs can break and cause exhaust leaks, commonly noted as a ticking type noise. The outer studs, clamps, and nuts will need to be replaced and are now being tightened to a reduced torque value (20 Nm/180 in lbs).

Software updates are available to address erroneous illumination of the "Service 4WD System" warning light and other issues (e.g. shifting, performance).

If the power door locks are buzzing or are intermittently noisy, a new door latch assembly may solve this. The door lock actuators are integrated into the latch assemblies.

The Check Engine Light may illuminate with code on or more of the following codes: P2302, P2305, P2308, P2311, P2314, P2317, P2610. Reprogramming of the PCM will be necessary to correct this concern.

A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.

During light to moderate braking, if you experience a vibration in the steering wheel, floor, or seat, or a minor pulsation in the brake pedal, installing revised front brake calipers may help. If the brake calipers are silver in color, they are up-to-date. If the calipers are black in color, the revised calipers are needed and should be installed along with new front brake rotors.

If water leaks into the passenger compartment and under the passenger side carpet, an heating, ventilation and AC (HVAC) drain hose is available.
