Engine Failure problems of the 2008 Dodge Caliber

For three sudden engine failures: 1) approximately April 16, 2014 noticed some of the dashboard warning lights blinked a little. Stopped at a traffic light it turned green stepped on the gas, the car jumped and stalled in traffic. Was able to restart the car and go about a 100 yards into a side street. Was met by local police. Got tow truck and had it towed to the local Chrysler dealer. After the car was repaired drove out of the dealer but noticed that a dashboard warning light was on. 2) approximately may 2, 2014 the dashboard warning lights blinked again but the car kept running. Drove to my destination. When I returned to my car, turned on the ignition key it would not start again not even to crank the motor. Got tow truck and towed it back to the Chrysler dealer. After the car was repaired, the warning lights were double checked, then drove out of the dealer. 3) approximately may 20, 2014 was going down hill hit a small bump causing dashboard warning lights to go on the car stalled, rolled the rest of the way down hill and pushed it into my driveway. I tried myself to fix it. Pulled off the main fuze cover and pulled out some fuzes this brought back some power to restart the car. The fuzes were apparently to the air bags but gave enough power to make the engine run. Made an appointment with an electrical repair specialist. Drove it to there lot. Was asked detailed questions on how I got there. The car was repaired but with problems, the electrical system is not protected in the front of the car and was advised to get a splash guard. But went to the Chrysler dealer parts department. Found that it wouldn't do much good and none exist to completely protect it. The car runs fine now but hazardous. I believe I shouldn't be paying repair bills for this fault.
