Other Fuel System Fuel Injection System problems of the 2009 Jeep Patriot

Bought car in Nov with clean carfax - 5months later it seemed to have a fuel injection problem. On way to the dealer, car did not stall, but speed dropped to 30-35 mph on the highway (engine light came on) had to drive in breakdown lane with hazard lights flashing, and on exit ramp shoulder . Trying to pull out into the driving lane on ramp- speed dropped to 5-10mph. - no acceleration. . Car was hit by another vehicle just behind the front left wheel - the car was totaled. . . Cause still unknown. Note: correction by consumer - the speed did not drop. . . The car would not go over 35 mph . . . . Believes it was also a transmission issue.
