Known Problems

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

The transmission extension housing seal may leak fluid, replacing the worn seal will commonly 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.

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.

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

Worn sway bar bushings or sway bar end links may cause a rattling or clunking noise from the front suspension during low-speed driving. Though not always the root cause, front struts are often replaced for this condition.

The fuel pump may fail causing the engine to stall and not restart.

Condensation in the heater case may cause a musty odor from the heating, ventilation and AC (HVAC) system after sitting for two hours or more. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.

Powertrain control module (PCM) software updates are available to correct false fault codes related to the oxygen (O2) sensors and evaporative control (EVAP) system.

The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.

In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

The car may drift to the right because the camber (alignment setting) is set unevenly. A 4-wheel alignment will be needed to reset the camber angle.

The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

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

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

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

The mass air flow sensor on higher mileage cars occasionally needs to be cleaned or replaced if sluggish acceleration is experienced or the Check Engine Light is illuminated with a mass air flow meter sensor fault code stored.

On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.

If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing differential clutch kit. An updated differential clutch kit available.

There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

Some vehicles may develop a musty odor coming from the HVAC system, Dodge has issued a cleaner/disinfectant and a coating for the evaporator designed to inhibit bacterial growth.

The engine mount on the right side can wear prematurely and cause excessive engine movement.

The anti-lock brake (ABS) warning light may illuminate due to an internal fault with the ABS hydraulic valve assembly. Our technicians tell us that replacement of the hydraulic valve assembly will be necessary to correct this concern.

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.

Failure of the catalytic converter can result in illumination of the Check Engine Light.

Oil can leak from the oil pressure sensor causing a loss of pressure at the sensor and illumination of the oil light.

The engine may stall at times due to a failed crankshaft position sensor and/or camshaft position sensor, These sensors can fail intermittently as they warm with the engine. Sensors on certain models have been recalled by Nissan and will be replaced as necessary. Please visit our recall section for this model to see if your vehicle is covered by this recall.

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.
