general problems of the 2007 Jeep Cherokee

As I was driving the truck jerked real hard which almost knocked the wind out of me and I lost control of steering, speed, I was unable to start the truck. I had to make my way to the shoulder in morning traffic on the highway to put the car in park and turn the ignition off and start it over again I had to do this 2 times before it started. Proceeded to get back into traffic and it jerked again this time it stopped running and started clicking all by itself until I stopped the truck and turned it off and started it again. This is not the first time this has happened and it very dangerous and from the looks of things this is a ongoing problem with this model & year Jeep.

Driving down road and engine stalled. Loss of power steering and power brakes. Put car in park and the car still moved wouldn't restart had to switch ignition off and take key out of ignition before engine would start. Stalls at random without any engine malfunction lamps. Hazard to be driving on road. Problem still unknown and vehicle is out of extended warranty.
