Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) [xxx] 4/21/2010 2005 Mercury marquis on April 17th 2010, at approximately 1 pm, as I hit the brakes approaching a stop sign, the brake failed and the engine raced, we traveled about 14 feet through the stop sign, the brakes worked again and the engine died down. Had there been a car in front of me or a pedestrian crossing I would have hit them. We took the car to a local shop on the same day, they diagnosed it and couldn't find anything wrong with it. On the 19th we took the car to a Lincoln Mercury dealer who also did not find anything wrong with the car. They had no suggestions for solving this dangerous condition. About 10 days ago I had the same thing occur, however, it was no more then 1 or 2 seconds and I was on the highway. Researching on the internet I found a number of cases of this serious problem with the Mercury and some other Ford products. This is very serious and must be remedied.

Email from congressman on behalf of constituent, regarding problems concerning abs brake system on Mercury and Lincoln vehicles.
