2005 Mercury Grand Marquis Problems

The car had 64600 miles on it and the headlights started going out while driving, which can be very dangerous. The problem is in the Light Control Module which is an expensive part (around $500 to $600 + labor).

A spring in the seat belt buckle may wear or fail, causing the airbag light on the instrument panel to illuminate. Failed buckles will require replacement.

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.

2005 Mercury Grand Marquis Recalls

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.

The battery cable includes a fusible link that may contact the #2 cross member. Over time, this contact could damage the fusible link. The damaged link could overheat and lead to a fire. Dealers will inspect the fusible link and position it away from the cross member. A damaged fusible link will be replaced. This recall is expected to begin on November 18, 2005. The Ford recall number is 05S38.
