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 popping or groan type noise may occur when opening or closing one or more of the vehicle doors. This may be caused bu insufficient lube on the lower hinge roller axle. Applying a small amount of grease between the roller pin and the inside surface should correct this concern. Our technicians tell us if the grease is not applied in the correct location, the noise will remain.
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.

One the 3.9L V6 and 5.9L V8 the carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.
On the 3.9L V6 and 5.2L V8 it is often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
If the alarm sounds without anybody disturbing the vehicle (usually in the middle of the night), a new hood striker plate is available. Made of thicker material, it will maintain contact with the hood switch as the vehicle's sheet metal cools.
Updated software will solve an intermittent problem where engine speed is limited to 3,900 RPM while driving.
