Brake Abs Warning Light problems of the 2012 Dodge Grand Caravan

Around 37,000 miles, check engine light came on, shortly after purchased, light would go off and on periodically. After a several weeks light stayed on and started blinking, at this time van was vibrating and sounded like it would cut off. Dealership ended up replacing engine head under warranty. A few months later light came on again, van did not want to accelerate, dealership could not find anything wrong with van. At times van does not want to accelerate as it should. After a delay, it will accelerate, but not like it should. Around 60,000 miles, abs light and traction light have come on and cruise control will no longer work. Back hatch door of van locked while open and would not shut. The door had to be tied down from the inside in order to drive it to the dealership. Dealership says hinges have been bent. Hinges have no marks of any kind, and there has been no damage to the vehicle. There's a whole lot going wrong for a 2012 vehicle.
