Mercury Grand Marquis Problems

Intake Manifold May Crack Leaking Coolant Behind the Alternator

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

Engine May Overheat at Idle With AC On

The engine may overheat at idle when the AC is on. A new, upgraded fan motor and resistor may be required to correct this concern.

Transmission Failure Common Due to Front Pump Failure

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

Mercury Grand Marquis Recalls

Headlights Fail To Operate

The lighting control module may fail, resulting in the loss of headlight operation. Dealers will replace the lighting control module free of charge to resolve the concern.

Potential Loss of Steering

Certain vehicles are being recalled because the upper intermediate steering shaft could separate resulting in loss of steering control. This recall includes models previously recalled under campaign #13V-385, these vehicles may have been incorrectly repaired. Dealers will inspect and replace the upper immediate shaft if necessary. If the steering column lower bearing has separated, a retainer clip will be installed.

Potential Loss of Steering

The intermediate shafts connect the steering column to the steering gear. Vehicles in areas where salt is used to de-ice the roads are being recalled because severe corrosion can damage the lower intermediate steering shaft. This can cause the upper intermediate shaft to collapse and separate at the lower steering column bearing. Separation will result in complete loss of steering ability. Dealers will replace the lower intermediate steering shaft and inspect the upper intermediate shaft and steering column lower bearing for damage, they will be repaired or replaced as necessary. If the steering column lower bearing has separated, a retainer clip will be installed.

Additionally, Vehicle owners located where salt is not used who have concerns regarding their steering will have a one-time option to have their vehicles inspected and, if necessary, repaired.

After that happened several times: the lat...
