Brand new truck with 1507 miles dumped all it's transmission fluid, emitting smoke from all sides and underneath, stopped vehicle dead in its tracks. Repairing dealer gave me one of the "wedges" left in the transmission cooler line at the factory which caused cooler hose to detach and precipitated major vehicle failure. It was just plain luck that we were not injured or killed as we were on our way to climb donner pass (CA) with chains on during a heavy snowstorm. Reported to Nissan customer satisfaction. I suggest NHTSA institute a recall for at least inspection as this factory defect cause total transmission failure at any time, with resultant risk of injury and or death.
