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).
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.
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.

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.

Absolutly the best car I have ever owned. I bought it used with 22,000 miles and have owned it for 11 years. Highway milage usually exceeds 27 mpg with cruise control. Local milage averages 17 mpg. This is the LS model and has automatic temperature control that still works perfectly - and the AC system has never been recharged. I am about to decide on whether to buy another car, or just sp...
