Carrier/rack problems of the 2009 Chrysler Pt Cruiser

I brought the car on 3/25/14 from a Toyota dealer ship. Complain about a knocking noise coming from the engine at the time of test drive. Toyota promise me it would be fixed pick the car drove it a couple of days and notice the control panel lights started going on and off along with the car shuting down. Took it back to the dealer for service nothing was found. I let my daughter drive the car and while on the fwy at 65mph the lights on the control panel starting going on and off they car shut off on her. Lucky she was able to guide the car over to the emergency lane avoiding from getting hit. I was in the hospital for about 4 months so car really wasn't driven that much. But I have this car less than a year with a protection plan and need transmission and engine work the envolved getting solenoid pack, bracket-torque reaction,t-stat, oil swith, gasket, and camshaft sensor and crankshaft sensor as of 2/10/2015. Now 2 days later the check engine light comes back on take it back to the dealer and was told I need a cooling fan module. Which is not covered under my protect plan and would have to pay almost 700. 00 dollar. I have this car less than a year and have been having so many problems and have almost gotten killed behind it cutting on and off on the highway. I have research this car and everyone has had the same complaint.
