I was driving on the highway when the oil pressure warning light came on, and then the engine completely failed. I was unable to restart the car while still coasting and was fortunately able to roll off the highway on to an exit ramp. In mid-day traffic, this could have been very dangerous. The car went straight to the dealership via flatbed - less than a year old, ~5300 miles - and it was determined the engine had seized. No cause was provided beyond 'oil exhaustion', and that there was no indication it was owner caused. The entire engine was replaced after 2 months, but I never received a full analysis or cause for the failure.
