2006 Mercury Grand Marquis ProblemsIntake 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.
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.
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.

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.

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.
