Camshaft Position Sensor problems of the 2011 Jeep Cherokee

I bought a 2011 grand Cherokee from shave Jeep in thousand oaks, CA. The vehicle started to malfunction within days after purchase. It would seize up, usually at highway speed, stall out, thus losing power steering and brakes. I brought the car in for service about 8 times until I almost got hit by a big rig on the highway at night when my car died. The constant engine light reading was a camshaft position sensor. Chrysler techs attempted to resolve the problem without any luck. Unfortunately the dealer swapped out cars with me and I found out they sold this vehicle without telling the new owners of the major mechanical problems.
