My wife and 4 year old daughter were struck by a 2004 mercury grand marquis on 04/21/16. They were driving in eastbound traffic in a 2008 nissan ultima and the driver of the mercury grand marquis was driving in westbound traffic. The driver of the grand marquis lost control of his vehicle and crashed into the vehicle of my wife and daughter. The driver died at the scene of the accident.
Dt: the vehicel accelerated suddenly and the brakes could not stop it. While in a parking lot to put air in the tires the vehicle just took off and crashed into a building. This happened july 30, 2005 the consumer is getting ready to contact ford.
My wife was driving our 2004 mercury grand marquis (pre-certified, bought off the showroom floor august 2004); our three teenage foster care children and I were passengers. Our marquis entered the parking lot of convenience store so that we could install air in left front tire. We did a u-turn in parking lot to proceed to air compressor. With her right foot on brake pedal, my wife steered the car through the u-turn, heading toward air compressor. Suddenly, without any warning, the car accelerated uncontrollably.
Tl* the contact owns a 2004 mercury grand marquis. The contact stated that while driving, the headlights failed without warning. The contact took the vehicle to the dealer and the dealer could not locate a problem with the headlights. The contact replaced the light switch but that did not remedy the problem. The failure mileage was 103,000. The VIN was not available.
On three or four occasions over a month or so, my headlights, which I turned on manually, went out while I was driving. The last time it occurred, I was on a dark, unlit, two-lane road and thought I would not get home alive. I pulled over, turned off the engine, turned on my emergency flashers and interior lights so that other vehicles would see me. When the road was clear, I started the car again, turned on the headlamps and proceeded to continue my ride home.
