Engine Noise problems of the 2012 Jeep Grand Cherokee

Engine light goes on blinks and car starts to shake had dealer look into engine. They stated the engine block needs replacement. This has been going on since I owned the Jeep. The car can stall at any minute and just shutoff. Driving on city streets engine light blinks for a few minutes the goes solid for a few days then goes off only to restart the process car always shakes and makes noises.

April 5, 2013, less than a year (purchased - 2012 Jeep grande cherokee laredo) the check engine light went on, took vehicle to service department, and informed my service provider (Jeep dealership) there is a "problem" with the cylinder head. Very disturbing because the vehicle was purchased brand new, less than 10k miles and already a major part must be replaced on a "brand new" vehicle. I am informed that is not a common, and there are several other owners with the same problem "check engine light on". Repair took more than three days, because the entire engine must be taken out to replace these two cylinders. Very alarming and very concerned for the future of this vehicle, what else could possibly go wrong next? two months later, driver side seat must be replaced due to cracks in the "leather". Two months after, brakes are making strange noises, acceleration very slow, stalls, must press very hard on gas pedal for vehicle to pick up speed, very frightening especially when entering the freeway. Door panels appears loose, the doors (3) will not stay open, requires extra push and hold before it stays open by itself. To close the door I must literally slam the door, otherwise not shut, very disturbing because my childrens sit back there. Hopefully this is my last encounter the cameras (back) of vehicle flash on and off, I am very concern especially when the position of the driver seat makes looking back very difficult, the camera cannot be functioning inefficiently. The vehicle has a 3/year or 36,000 mile warranty and with the amount of issues I have encountered I do not find that to be sufficient or even utterly appropriate. I purchased a brand new vehicle not a used. If there were no warranties I could not imagined paying out of pocket thousands of dollars on repairs.

We purchased a new Jeep Grand Cherokee with 5 miles on it. Upon leaving the dealership the engine began making a strange noise. We brought the car back to the dealer and the mechanic told us to leave the car. It's 5 days later and all we know so far is that they have removed the front end of the transmission and they are still working on it. We don't have the car. Additionally, the front driver's side door was not flush with the body of the car. We asked them to look at the door to see if it was not installed properly. They offered to have the body shop bend the door.
