2004 mercury mountaineer sometimes jerk really hard when put in reverse gear. Twice, it jerked so hard, I had to slam on the brakes, cause it was backing back fast. Really scared me. Other times, it jerks hard, but stays put until I press the gas. I never know when this will happen, there is no warning. Took truck to mercury dealer once, over a year ago. Said they checked, but couldn't find anything. Vehicle is paid for. No longer have warranty. About 3 weeks ago when the last jerk occurred.

I purchased a 2004 mercury mountaineer v6 in april, 2004. I immediately started to notice a harsh jerk when putting the car in reverse and sometimes while driving forward. It sometimes felt like driving a 5-speed vehicle. In late september, 04 while backing out of my driveway, me and my 13 yr old daughter experienced a very harsh jerk as if someone had slammed in the back of the car. We were both shaken. I started to experience neck problems. I made my first dr. Appt. In early to mid october 2004 and was told that my vertabre was out of place. When the recall notice came in february 2005 (I believe) to me, I took my car to be repaired and I was told that it would take at least 4 hours to fix. It actually took the dealship 3 days to fix it. The auto technician told me that my car was worse off than others that he'd seen before with the same problem and additonal parts had to be ordered. My car is working okay now that it has been fixed. On the other hand, I have been to the doctor several times with this neck injury. I have had x-rays, mri and ultra sound completed. The jerking of my vehicle has caused injury to the #2 vertabre in my neck. I experience head aches, severe neck pain, and shoulder and back pain. I have been to physical therapy- recommended by my doctor and to the chiropractor. I have a very hard time sleeping and working due to this pain. I called ford motor company to alarm them of my injury due to the defective transmission in the vehicle that they manufactured. The individual that I spoke with was very rude, non- caring of my injury and spoke to me in a negative tone. I was told that there were no medical provisions on this particular recall. To this day, I am still in constant pain. I have suffered long enough and I feel that it is time for ford motor company to own up to the rresponsibility that their defective vehicle has caused an injury.
