AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.
Recalls
NHTSA recall #05V520000November 9, 2005199,942 vehicles affected
visibility: windshield wiper/washer: motor
On certain trucks, passenger cars and sport utility vehicles, the windshield wiper motor may have been produced without grease being applied to the output shaft gear.
After a period of continuous use on the high speed setting, lack of grease on the output shaft gear may cause the gear to distort or fracture during operation resulting in a loss of wiper function. Inoperative wipers under inclement weather conditions could cause a crash due to impaired visibility.
Remedy
Dealers will inspect the wiper motor for the presence of grease and grease the wiper motor gears if necessary. The recall began on november 22, 2005. Owners may contact Ford at 1-800-392-3673 or Lincoln/Mercury at 1-800-521-4140.

About this data
NHTSA complaints and recalls through October 2026. Complaints are counted once each, however many components they name. Original complaints are on NHTSA's page for the 2006 Mercury Mountaineer.
Problem groups are formed by AI and may be approximate. BrakeNews flags unusual complaint patterns; they are not official defect findings. Investigation reports are written and checked by AI, with no human review. Owner reports do not establish that a defect exists.
