Unexpected acceleration of 2008 Mercury Grand Marquis, while my foot was on the brake, slowing the vehicle. This happened twice in the past 3 days. Second incident occurred Oct. 31, 2008. Each incident nearly caused my vehicle to strike another vehicle.

The first time I changed the oil in my 2008 Mercury Grand Marquis when I started the engine there was a loud mechanical noise for a few seconds. I took it to the dealer and told him to change the oil and listen for the noise which they heard and was told all 2008 Grand Marquis do this.also I notice the engine is noisy in the morning when I start it. I think Ford has a problem with these engines if they all do it.

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.
