Mercury Grand Marquis owners have reported 4 problems related to radio/tape cd player (under the equipment category).
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 electrical problems, it has blown the motors which control both the power seats. I have had the wiring fixed but not the motors replaced due to the expense involved. I feel like I have a real lemon on my hands as well as an unsafe vehicle.

Just bought the 2008 Grand Marquis, first day, radio did not work, (still does not work properly). Took the car in for oil change 2500 miles, also asked them to check out a noise the car was making. I was just informed yesterday I need a new engine. They the dealer said it was something to do with the timing chain at first the replaced that part and still had the noise. I will never own a Ford product, and they wonder why they are losing market share!!! by the way, this is my 9th Grand Marquis, I just traded an 2005 to get rid of it, it too had a noise they could not fix. Now my wife will not even drive this one when we get it back from the dealer.

Consumer stated there was a rattling noise coming from the engine when cold, dealer informed consumer the timing gear needed to be replaced, also the dashboard vibrated, however dealer stated nothing was wrong, the trim panel was loose on the door, the left front door closed too hard, the vehicle would lean to the left and there was a noise coming from the front of the vehicle when turning a corner, dealer replaced the front frame supports, the instrument cluster was scratched, the steering column trim was replaced, the radio had a poor reception, there was a pulsation coming from the brakes, however the dealer could not duplicate the problem.

When the vehicle is started, an unusual noise occurs in engine, especially in the morning, then gradually gets louder/more frequent. One day in particular, the vehicle was parked(hot weather), and when the vehicle was started, the noise started again, and was extremely loud/distracting to others. The dealer cannot duplicate, stating that all the models sound this way and is the timing chain. Other problems are as followed: radio static/window static-when the ignition is on(may be a loose wire, and when the brakes are applied, it engages the brake light switch. The consumer requests that the problem(s) are fixed before the warranty expires. Scc.
