NHTSA Complaint #10535618 — 2011 CHEVROLET EXPRESS

WHILE TRANSPORTING A PATIENT IN THIS AMBULANCE THE DASH WARNING NOTICE CAME ON WARNING THE DEF TANK LEVEL WAS LOW AND THE VEHICLE WOULD SOON GO INTO LIMP MODE. THE DEF TANK HAD JUST BEEN FILLED TO FULL. STRANGE READINGS CONTINUED TO APPEAR WARNING OF EITHER JUST A FEW MILES OR OVER 2000 MILES.I WAS AFRAID OF HAVING A PATIENT DIE IN OUR AMBULANCE IF THE AMBULANCE WENT INTO LIMP MODE ON A LONG TRANSPORT TO PHOENIX SO I TOOK THE AMBULANCE TO THE DEALER WHO REPLACED THE DEF TANK FOR $1547.33. I WAS TOLD BY ROSE AT THE GM CUSTOMER COMPLAINT LINE THAT EMISSIONS PROBLEMS SHOULD HAVE BEEN COVERED BY WARANTEE BUT I CANNOT GET MY MONEY BACK. GM STATES THEY HAVE NO REPORTS OF THIS PROBLEM OCCURRING BUT THE INTERNET IS FULL OF SIMILAR COMPLAINTS.
