No warnings, no check engine lights NOTHING! It just completely shut off and would not turn on.

• “NOTICED BURNING SMELL COMING FROM UNDERSIDE OF VEHICLE AND OIL-LIKE SUBSTANCE ON FLOOR OF GARAGE AFTER DRIVING. TOOK TO THE DEALER AND WAS INFORMED THAT THE TRANSFER CASE FAILED AND WAS LEAKING FLUID ON EXHAUST SYSTEM. RESEARCH INDICATES THIS IS A KNOWN DESIGN ISSUE IN MULTIPLE YEAR MODELS OF MAZDA VEHICLES AND I FEEL DUE TO THE SIGNIFICANT FIRE RISK OF OIL/LUBRICANT DRIPPING ONTO THE EXHAUST SYSTEM, THIS SHOULD BE SUBJECT TO A RECALL.”
