What 2010 Mercury Grand Marquis owners say
Steering
the lower bearing separates, the vehicle may experience a loss of steering, increasing the risk of a crash. Improper servicing of the upper intermediate shaft could cause the shaft to separate, which can then result in a loss of steering control, and increasing the risk of a crash
The road was dry and bare. I felt a right rear skid (?"black ice"). I tried to turn steering wheel to correct the skid and it was locked. It jerked out of my hands, the engine roared and the car flew to the left across the road into a large tree. I had no control over the steering wheel. On impact of the tree, there was no balloon with air bag deployment, only pungent fumes and white flecks. The car was towed and totaled.
Body & structure
I was pulling into a parking space and had almost come to a stop when the vehicle suddenly lurched forward & hit a (vacant) store front. I feel the vehicle accel- erated on it's own as I was applying the brake at the time, my foot did not slip off of the brake. The vehicle is equipped with "drive by wire" or, no cable is attached to the throttle body from the accelerator. The dealer repaired the front end of the vehicle and extensively examined the throttle system. No apparent cause was determined and they told us it May never happen again. We have traded the vehicle in since repairs were completed due to lack of confidence in it.

Speed control & acceleration
Yesterday, Tuesday 23, 2014, I backed out of a parking spot on the parking deck about 15 feet and put the car in drive. 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. Ems arrived and checked me over. A police report was filed. ..updated 06/26/14
