While driving there was an internal failure of the front differential which caused debris to fly out and the debris then punctured the transmission according to the diagnosis on an Audi dealership. The car jerked to a stop and would not move. If this happens at high speed it represents a sever safety risk to the occupants. The vehicle has been inspected by the manufacturer and insurance representatives as well as by a dealer. There were no warning lamps, messages or other symptoms and this happened with no warning.

Engine malfunction prevented the vehicle to engage and a significant lag. Correction of the failure has been attempted twice and a third attempt to correct malfunction is currently in progress with no movement as of yet. Gas tank has been drained and refilled and did not correct issue. Definitely not a gasoline type issue.
