We have had numerous failures in the braking system. This started with occasional spongy pedal issues that resulted in replacement of the brake booster. This started a two year long journey to repair brake issues. This has gone thru two of the most reputable auto mechanic shops in our area. We have gone thru three brake boosters, one master cylinder, and about to replace the second ABS hydraulic unit. The ABS hydraulic/module unit is the most frustrating because it is failing at such a rate the mechanics cannot get them new and we have had to use refurbished ones. This is a tremendous safety issue and we as consumers are working diligently to repair the issues... only to have erratic unsafe braking conditions. This is a huge lawsuit waiting to happen if Ford/Lincoln does not address the issues and research a solution.
