While driving this car during winter with moderate blowing snow, the engine would act like it was cutting out. No check engine warning or any other indication what was causing this. Finally got a check engine light and drove right back to dealer. Left car running while I talked to the service advisor. A car jockey reached in and shut it off. Service advisor got in and started the car but the check engine light was out. Put in their diagnostic tool and nothing showed. This has happened several times since but only when you have blowing snow. Car washes, driving rain, slush and snow do not effect it. Only wind driven snow.
