More on this, but after weeks of -5 C to -30 C weather, my Ecodiesel suddenly would not turn over. Got it towed in to the dealer and they said that the engine needs to be replaced. More details to come on the cause as I learn more. The issue apparently is that the cold weather cover for the grill must be installed and anytime the temp dips below 0 C, the truck must be plugged in?? Crazy. The engine will be replaced under warranty (this one time). Has anyone heard of anything like this?? I've had diesels in the past and cold weather starting can be an issue but nothing like this.
