2008 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.

Wheel May Separate from the Vehicle

Improper heat treatment of the wheel bearing and hub assembly may allow the hub to fracture. If the hub fractures, the wheel will only be retained by the brake caliper assembly. If the wheel falls off while driving, a crash could result. Dealers will inspect and replace both front wheel bearing and hub assemblies free of charge. The recall began June 22, 2007. The Ford recall number is 07S54.

A nice, comfortable car, with decent mileage. I have 50,000 miles on it, with the original brakes and tires.... only expense other than maintenance is the climate control unit had to be replaced at around $1,000, soon after it ran out of warranty. Since they don't make them anymore, I think I'll have this one till it quits.
