2006 Mercury Grand Marquis Problems

Malfunctioning Headlights

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).

Spring in Seat Belt Buckle May Fail

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 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.

2006 Mercury Grand Marquis Recalls

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.

2006 Mercury Grand Marquis Reviews

The car runs great but in the 2006 model there is a glitch the automanic temp control head. This had to be changed twice. The fist time was becuase the heat was coming from the vents and the unit was not on. The second time is the lights for each button was not working, so at night time you can not see your selection.
Love the car..too bad they will no longer be making it. The EATC Module is a real stinker...$960.00 to replace it and all that is wrong is the "O" rings were cheap crap. There should be a recall on this Cheap piece of junk part.
EATC climatic control is no good! Other wise a good car.
