problem #5

Apr 172010

Grand Marquis 8-cyl

  • 36,000 miles


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.

Both front inner brakes not properly contacting rotor. Only a 1 inch width of inner brake pads have ever contacted rotor. Based upon the amount of rust and pitting of the non contact area of the rotors it appears that the brake pads were never contacting properly. In all my years of servicing vehicles I have never seen this type of defect before.

While slowing for a red light, pressed brake pedal and vehicle immediately accelerated becoming uncontrollable. Collided with a pick up ahead, which was pushed into a small compact ahead of it. Airbags did not deploy. Had experienced slight acceleration on a previous occasion, which was discussed with my mechanic. ( had also had this problem on my 1999 Ranger which was resolved by replacing iac motor.) vehicle currently in dealers shop, where service personnel are unable to replicate occurrence nor find source of problem. Ford Motor Company disclaims any knowledge of problem although many several similar events involving this model year are well documented. Vehicle is well within warranty parameters but little, if any, action is ongoing. I am reluctant to resume operation of this vehicle while condition persists.

2005 Mercury Grand Marquis brake failure. * the consumer stated when he attempted to apply the brakes, the vehicle slowed most of the way down to the stop, then the consumer lost control of the vehicle and ended up stopping 10 to 20 feet of where he intended to stop. The consumer believed there was a serious brake issue with the vehicle. The consumer returned the vehicle to the dealer and the contract was cancelled. The consumer stated a rented a 2006 Lincoln town car and it exhibited the same brake failure twice in a short time. The brakes did not stop the vehicle in a controlled manner. See also 10184790.

: the contact stated while applying brake pressure at low speeds, a squeaking noise was present. The vehicle was inspected by a dealer who determined the squeaking noise was normal, and that was the way the brakes were designed. The manufacturer was not alerted. Updated 01/10/07.
