2002 JEEP Grand Cherokee 4.7 v8 ENGINE FROZEN DEAD

Jeep stalls three times and starts up and then shuts down with no warning. Had the car towed to a local mechanic and and they said the Engine was Frozen. It will not turn. Had the car towed to the dealer and was confirmed the engine is shot.

Jeep has 92000 miles on it. I thought these were known to go over 200k miles.



Any body have the same issue with the engine.

Is this a known/ common problem?

Any input or thoughts would be greatly appreciated.



Thanks
