Known Problems

The fuel tank may become hard to fill and/or the fuel fill nozzle may shut off repeatedly while fueling. Our technicians tell us that various items including the fuel tank, vapor recirculation tube, fuel fill tube, or EVAP system canister control valve may be at fault. Proper diagnoses will be required to determine the exact cause of 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.

Loose or worn suspension and steering components can cause a wobble or shaking in the steering wheel. It may happen at a certain speed and subside as the vehicle accelerates through the range. Tire balance can contribute to this as well.

Owners have reported several instances of the interior door handles coming loose or breaking. The factory door handles are part of the entire door panel, so an OEM or factory repair would require replacement of the door panel at considerable cost. There are multiple aftermarket solutions involving removing the door panel to repair the original assembly, or retrofitting an aftermarket interior handle to address the issue.

For the first few miles driven (before the brake pads warm up), the rear brakes may squeal with light brake pressure. Updated rear brake pads are available.

Vehicles equipped with manual transmissions may become difficult to shift. The repair may involve replacing the 3rd/4th/5ht & reverse gear synchronizer rings as a set.

3.7 V6 and 4.7 V8 engines may develop exhaust leaks due to broken exhaust manifold bolts. Exhaust manifold gaskets and bolts should be replaced as necessary.

The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.

Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).

Failure in the blower motor power module (automatic temperature controls) or resistor block (manual AC) may cause the heater blower motor to work only on the high setting. The connector to the power module/resistor block is known to overheat (and sometimes melt). The connector or terminals should be replaced; a replacement connector is available.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Low fluid level in the differential or transfer case can result in bearing failure. Damaged bearings commonly cause a whine or growl type noise.

The door molding may become loose on one or both front doors. Our technicians recommend to replace the molding if this occurs.

On Vehicles with a 4.7L or 5.7L V8 engine, the Check Engine Light may illuminate with code P2181 for a cooling system performance fault. Or technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.
