Splicing on almost all electrical systems had come apart. Affected were the radio, clock, windows, power seats, lights, door locks, trunk release inside car, low tire monitor warning light stayed on constantly, seat belt warning light stayed on, warning bell for key in ignition stayed on except when car was moving, dome light would not go off whenever you got out of car. Some of these problems were constant and some were intermittent. As a result of the locking problem, our vehicle was stolen, but thankfully found with no damage. With no help from our local Ford dealer, I finally called the Ford motor co. Complaint dept. And was told to get a diagnostic test run on it, which I did at another dealers, and that is when they found the wiring splicing problem. As a result of the elec

My 2010 mercury grand marquis has a defective throttle body, it left me terrified and stranded on I-95 south in the center lane of a 70 MPH 3 lane interstate. The engine all of a sudden went to dead idle, gas pedal was inoperative, I still had steering and brakes but didn't have the ability to get over on the shoulder with cars and big trucks scrambling to get around me, thank god it was daylight. While we had decelerated to about 30 MPH my wife stuck her hand out the passenger window waving frantically and some extremely smart truck driver realized we were in trouble and let us over to the right lane in front of him an then onto the breakdown lane. After several attempts of shutting down and restarting it finally went back to operating properly, when we got home I called Ford motor compan

It lurched forward at a tremendous high speed and although I hit the brakes, the auto slammed into the retaining wall at the parking spot I had just backed out of. I was wearing my seat belt and the air bag deployed. I received minor bruising on my arms, legs and ribs due to the air bag deployment. This auto has side air bag as well, but only the drive air bag deployed. I was checked out by a medic, who was staying at the resort and heard the crash. There were no witnesses.

While driving on expressway at night in a driving rainstorm, my wipers quit working. I was able to pull over until the rain stopped, but could have been a disaster. On april 23rd the dealer diagnosed the wiper motor assembly was bad. P/n 8w7z*17508*a. I have found since the redesign of wiper motor assembly in 2003, that the wiper motors get water in them and short or corrode the integral wiper electronic board. Even thought the failure rate may be low, the potential for a disaster, like I could of had is great. This part should be redesigned and effected vehicles recalled. I have no complaint with the dealer work. *tr
