The head gasket may seep oil externally. An updated head gasket is available that will prevent any more oil seepage.

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.

4.0L 6 Cylinder
Due to misfires, you may experience a loss of power when accelerating between 50 and 70 MPH (most noticeable below 32° F). This is commonly caused by carbon buildup on the valve stems, as a result the exhaust valves may close too late. All of the exhaust valves should be inspected and if necessary the engine should be decarbonized.

A cleaner/lubricant is available from Mopar for when the soft top window zippers become stiff or difficult to move. Our technicians note this product works very well when the directions are followed properly.

Jeep issued an emissions recall in late 2006 to update the powertrain control module (PCM) software on certain 1997 - 1998 vehicles. As part of the recall, the catalytic converter will also be inspected for damage and replaced as necessary. To see if your vehicle is included in the recall you can visit the Jeep website (owners' section) that allows owners to input their VIN number and check the recalls on their vehicle.

Our technicians tell us that various dirveability and Check Engine Light issues can be corrected by updating the powertrain control module (PCM) software.

"False" trouble codes may cause erroneous illumination of the Check Engine Light. Updating the PCM software can often correct this concern.

If the radio station or CD track changes when the steering wheel volume control is used, a revised body control module (BCM) will fix the problem.

The 3.7L V6 and 4.7L V8 in very cold climates (below freezing temperatures) moisture can collect in the Positive Crankcase Ventilation (PCV) system and freeze. This will cause various drivability problems and there are revised PCV system components to repair this concern.

On 4x4 vehicles, the Electronic Stability Program (ESP) may not turn off when the "ESP off" button is pressed. Our technicians tell us a software update for the anti-lock brake system (ABS) control module is available for this concern.

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

An abnormal noise and/or vibration may be noted from the front brakes during light braking. Our technicians tell us it may be necessary to replace the steering knuckle and hub assembly, along with resurfacing the rotors to correct this concern.

A chirp type noise may be noted from the serpentine belt when the steering wheel is at full lock with the engine idling. Our technicians tell us a revised serpentine belt tensioner is available to correct this concern.

A ringing sound may be noted from the driveshaft when shifting from drive to reverse and reverse to drive. The repair may involve replacing the automatic transmission output flange and applying "Stud N Bearing Mount Adhesive" to the transmission output shaft flange splines.
