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 #05V086000March 14, 200543,626 vehicles affected
service brakes, hydraulic: foundation components: hoses, lines/piping, and fittings
On certain passenger vehicles built with electronic traction control, the rear brake line may chafe due to contact between it and a floor pan stiffening rib, and a brake fluid leak may occur.
The brake pedal may develop a "spongy" feel and drops of brake fluid may be observed beneath the vehicle. Over time brake performance may be compromised and stopping distances could be extended which could lead to a crash.
Remedy
Dealers will inspect the subject vehicles for contact between the brake tube and floor pan stiffening rib. If contact is evident, but no abrasion or leaks exist, the brake tube will be repositioned to preclude further contact and potential abrasion. If indication of abrasion or a leak is evident, dealers will repair the brake line. This campaign began on july 15, 2005. Owners may contact Ford at 1-800-392-3673.

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 1997 Mercury Marquis.
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.
