2006 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.

The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle, hard starting, hesitation on acceleration, poor fuel economy, and stalling.

2006 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.

2006 Mercury Grand Marquis Reviews

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.

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.

EATC climatic control is no good! Other wise a good car.
