Known Problems

Poor fitment of the headliner, which may or may not develop into a rattle noise around the sunroof area is generally caused buy foam isolation blocks becoming detached from the headliner. The repair involves re-securing the foam blocks using cable (zip) ties.

The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.

The trunk lid may not latch closed, this is generally caused by the trunk latch sticking in the open position. Our technicians tell us that in most cases the trunk latch assembly will need to be replaced to correct this issue.

A cosmetic crack may develop on the plastic liftgate trim panel. Lincoln has released a service procedure to replace the applique without damage the the liftgate glass.

Sagging suspension can be a result of air suspension struts and/or drier leaking air. These type of air leaks can lead to failure of the air suspension compressor.

Various radio performance concerns may develop including noisy operation, no operation, or SYNC issues. Reprogramming the appropriate module with updated software will commonly correct most of these issues.

A grunting or grinding type noise may be noted from the front brakes. Our technicians tell us the problem is generally caused by the front brake caliper anchor brackets which can cause abnormal brake rotor and pad wear. The repair commonly involves replacing the brake pads and rotors and updating the caliper anchor brackets with revised parts.

An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

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 1996-2011 Lincoln Town Car 4.6L V8 engine is known for displaying the normal symptoms of a coolant leak, including overheating, especially when the vehicle is idling, the strong smell of coolant from the engine, and illumination of the low engine coolant warning light

This leak is difficult to locate as it is buried underneath the intake manifold, and only begins to leak coolant onto the ground in advanced stages of disrepair. This leak springs from the heater tube, which allows coolant to flow between the water pump and HVAC heater core

When the connection for this tube begins to leak, the coolant burns on the hot engine, and produces a sweet smell that is unmistakably engine coolant. 

The remedy can be complicated, and will necessitate removal of the intake manifold, heater tube, and possibly the water pump. After removal of these items, the connector may be replaced, or a set of o-rings, depending on the year of the vehicle. Most vehicles, model 2002 and later, will have o-rings, and the water pump will not need to be removed. 

Incorrect cabin temperature can be a result of a broken temperature blend door. Our technicians tell us if this occurs, the complete heater case will need to be replaced.

Spark plugs in the Lincoln Navigator can be very difficult to remove.

Ford has issued a service bulletin (08-7-6) to address this issue, which includes a recommended procedure on how to remove the plugs. Failure to follow the recommended procedure can result in the one or more spark plugs breaking off in the cylinder head.

The recommend procedure is as follows. Using this procedure will greatly reduce the chance of breaking a spark plug.

1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the treads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.

There are special tools available to remove the broken spark plugs and repair shops will often charge additional labor for the removal of each broken spark plug.

The ignition key may become stuck in the ignition lock, possibly associated with a binding shifter bezel. Our technicians tell us that if the shifter knob is sticking or the shifter bezel is binding the affected part should be replaced.

Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.
