Front Suspension problems of the 2005 Jeep Liberty

My wife and I were returning from vacation when without warning the car acted like it was going over a wash board surface for a few seconds and then came a loud bang and then no power. The vehicle pulled hard to the left briefly (we were in the passing lane). I struggled to get the car over to the right shoulder and shut it down. There was a trail of oil on the highway and it continued pour oi out of the engine after I stopped. Prior to the incident, the car was running correctly and none of the warning lights on the instrument panel came on until after the event. The temperature gauge was at its usual twelve o'clock position. Once off the road I opened the hood. There was oil all over the bottom of the engine. The serpentine belt and the tensioner pulley had been ripped off the engine. With a flashlight, I could see the front few inches of the front skidplate. The were fragments of metal on it along with oil. I checked the oil filter under the car and it was intact. The car was towed to gator Chrysler-Jeep in melbourne, FL. The car was examined on 11/30/2010 by the diesel tech who told us that he had never seen one of these engines fail like this. He also told us that he had spoken to a Chrysler engineer and that engineer said much the same. The tech told us that he had found two holes in the front of the engine block and that the skidplate was covered with shrapnel from the engine. The tech also told us that the oil pan looked like someone had taken a shotgun to it. A dealer service writer showed me at least one of the other holes found toward the back of the block on the passenger side. I put in a claim with Chrysler. It was rejected. They claim "insufficient lubrication". According to the service manager at gator, they did not open up the engine to see what really happened as Chrysler would not authorize such activity. Vehicle year: 2005 vehicle make: Jeep Liberty limited 4 x 4 engine: 2. 8l turbo diesel mileage at failure: 77,594.
