The engine turned off while driving TWICE with NO WARNING. The first time the engine turned off without warning doing around 60MPH but was able to be restarted and ran normally for about a week or so. The second and final time that the engine turned off without warning was about a week after the first incident. The engine would not restart, in fact, it would not even crank. The vehicle was towed to the dealership where it was determined to be a crankshaft bearing failure causing a bottom end engine failure. Metal shavings were found in the oil pan. Vehicle is only 14 months old and has 22,754 miles. All service was done by dealer at manufacturers suggested intervals.
