NHTSA Complaint #10651011 — 2014 FORD MUSTANG

UPON ACCELERATION TO PASS A SLOW VEHICLE A STRONG ODOR STARTED TO FILL THE VEHICLE, ALMOST LIKE A PROPANE SMELL. THIS I LATER LEARNED TO BE EXHAUST FUMES, OR I SHOULD NOTE, UNBURNED FUEL PASSING THROUGH THE SYSTEM. THIS IS THE 3RD TIME THIS HAS OCCURRED, AND ONLY DOES THIS UNDER ACCELERATION WHEN PASSING SLOWER VEHICLES OR USING MORE POWER TO ASCEND HILLS OR MOUNTAIN TYPE ROADS. VEHICLE THROWN NO SES CODES. VEHICLE DOES NOT STUTTER OR HESITATED, BUT AS NOTED DOES PRODUCE A FOUL SMELL UNDER HARDER ACCELERATION. *TR
