“After driving to mall my daughter realized that my head lights were not on. Checked all fuse (under dash and under hood). None were blown. Realized that had no dome light but did have map/reading lights. No tail lights or brake lights except third brake lights. Had brights if I held high beam lever. Had car towed to shop. Was told that it was the light control module (lcm). Was told that ford had and extended warranty on this part. Took it to ford dealer. They said that it was only for the 2003-2005 models and that my car was not covered. …”

“During height of the rush hour at 4:00 pm I was traveling on nj turnpike at 65 MPH in the middle lane, started to hear a clicking sound. All of a sudden the car's engine stopped, had no power steering and the entire electrical system failed, (the car's battery was replaced in 12/2010) . Directional signals, and emergency flasher did not work, nor could I lower the windows. I was able to coast to the shoulder of the road when a slow moving truck was coming up on the right side. No clicking sound was heard trying to restart the car.”

“Problems with my wife's 2002 Mercury Grand Marquis ls not cranking at odd times. I have cranked up the car, and driven it into the garage, then go back out a couple minute later - 15-30 minutes - and the car would not crank. The last time I pulled the car into the garage one evening and when my wife went to go to work the next morning it would not crank. The dealer's service department can not find a problem. However, the left turn signal went out about a year ago, requiring a module be replaced. …”

“Shortly after purchase we went back to dealer to complain about bouncy suspension that made the car go sideways on the highway when going over bumps while in mild turns (just highway direction changes not getting off/on, etc.). Dealer looked into problem via fmc and said the 02 suspension had been changed to improve its ride (ha). The changes were too great to be able to change components to get the ride back to what it was in earlier years. …”
