While driving at highway speed my 2015 Jeep Grand Cherokee eco diesel started to make a rumbling noise, the oil pressure light came on within a minute the engine shut off still at highway speed. When I pulled over to the shoulder the car was stuck in gear, would not restart and had a small oil leak. The car was towed to the nearest dealer who determined that the car had engine damage and the engine needs to be replaced. Car has less than 33,000 miles and still has original tires, and brakes. All oil change services were performed as suggested. Car was purchased new from dealer August 4th, 2015.
