The dealer refilled both tanks (passive & active). The passive tank was empty. The tech could not tell if there was a leak as we had a severe snowstorm today leaving the vehicle dripping melting snow from everywhere. He said he wasn't sure if the vehicle was shipped with the tank partially full. The new vehicle delivery checklist did not include topping off the urea tanks. Time will tell. If this recurrs within another 2000 mi, then there is definitely an abnormal situation unfolding. I'm skeptical.
