With 2,700 miles on my new Dodge Durango, i was in park in a lot idling, the engine started to tick and then miss badly. Had to have it towed to the dealer by Chrysler. They said it had a mechanical head failure (valve stuck), it bent and broke 2 push rods on #5, but said the valve didn't hit the piston. The replaced the head, 2 push rods, and all of the lifters on the driver's side bank. I saw the valve and didn't notice any obvious damage, but now it runs sluggish. Waiting for the dealer to advise on the problem and resolution.
