One problem related to engine has been reported for the 2001 Jeep Wagoneer. The most recently reported issues are listed below.
The consumer stated while driving at 35 mph the motor dropped out of his vehicle. He said it sounded as if he had ran over something, but when he pulled to the side and got out it was a different story. He said he walked back about 10 feet and picked up a part, that looked like a part of the engine, then walked some more and picked up a piston ring, all of the time the oil was just running from the motor. The consumer bent down and looked under the vehicle and there was a whole in the bottom of the engine.
