Known Problems

The turn signal switch may fail causing the hazard/turn signal flasher to continue to click even when the turn signal switch is off. Replacing the faulty turn signal switch will commonly correct this condition.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.

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.

A surging or bucking during acceleration can be caused if the distributor is moved or mis-indexed. This is a result of the cam and crank position sensors being out of synchronization. Wear of the oil pump drive gear can cause similar symptoms because it allows excessive free play in the distributor drive. The distributor drive gear and bushing should be replaced if the rotor tip moves back-and-forth more than 3/16th of an inch when checking drive gear free play.

The anti-theft system may cause a no start condition due to electrostatic discharge (ESD) affecting the wireless control module (WCM). There is an updated WCM to correct this issue.

Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.

Coolant leaks coming from the underbody on vehicles equipped with rear heat/AC are common. The underbody hoses should be inspected as part of regular maintenance. If you drive on roads where salt is prevalent the problem is generally more severe. Some 2005 models are involved in a special service action, no government recall was issued.

Triggered by a short in the rear wiper motor/circuit (which causes a fuse to blow), the airbag warning light can illuminate erroneously.

Timing cover oil and coolant leaks are common, the oil and coolant don't normally mix. Our technicians recommend to replace the timing chain and cam sprocket if the timing cover is removed to reseal - or for any other reason.

Excessive oil consumption—defined as more than one quart per 1,000 miles (on vehicles with less than 50,000 miles) or more than one quart per 750 miles (on vehicles with more than 50,000 miles)—is common. Common causes include exhaust valve guides, valve cover gaskets, camshaft plugs, camshaft seals, and crankshaft seal.

Valve cover gasket leaks are common after 60,000 miles. Symptoms will include oil drips under the vehicle and burning oil smell from the engine compartment.

One vehicles equipped with power folding mirrors, the mirror may fold out past the standard position. Our technicians tell us that if this occurs a special procedure must be followed to relearn the correct mirror home position.

It is not uncommon for the exterior light bulbs to burn out prematurely. No repair option has been reported other than replacing the failed bulb.

There have been reports of a failed ABS Control Module causing the ABS and Check Engine warning lights to illuminate. Repair or replacement of the failed module will be required to correct this issue.

The head gasket has a high failure rate due to cooling system problems. Subaru is aware of the problem and has extended the warranty to 8 years/100k miles on many vehicles.

The AC compressor may fail causing the AC system to blow warm air, smoke may also appear from the engine. A failed AC compressor will require replacement. Mazda has extended the warranty on these compressors to 5 year or 60K mikes. If these conditions are noted our technicians recommend to turn the AC system off and have it inspected as soon as possible.

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

The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

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.

Brake pads and rotors may wear out prematurely. This can be heavily dependent on driving style. Our technicians recommend regular brake inspections with replacement of pads and rotors as required.

On certain models the windshield wipers will not park in the proper place or won't shut off. The wiper motor must be replaced to repair this issue.

Water leaks may be noted from the front and/or rear roof area. Our technicians recommend to inspect the roof ditch and sunroof - Check all grommets and plugs, reseal roof seams, and replace the sunroof drain tubes if necessary.

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

On the 2.7L V6 and 2.4L 4 Cylinder, a defective exhaust gas recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.

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.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
