THIS IS A FOLLOW UP TO NHTSA ID 11019920 FILED 8/26/17. EXHAUST ODOR, SMELLS LIKE SULFUR, STRONG, PUNGENT, COMING THROUGH DAHS BOARD VENTS DURING SUSTAINED ACCELERATION AND SHORTLY AFTER. THE PROBLEM IS REPEATABLE EVERY TIME: PUT VENT SYSTEM IN RECIRCULATION MODE, SUSTAINED ACCELERATION OVER 3,000 RPM, WAIT 5 SECONDS, STRONG SULFUR ODOR COMES THROUGH DASH BOARD VENTS. I AM NOW EXPERIENCING HEADACHES ON A CONSISTENT BASIS AS I HAVE BEEN DRIVING THE VEHICLE MORE OFTEN FOR COMMUTING SINCE PURCHASING IT IN MARCH 2017 WITH 25K MILES. I AM SEEING A DOCTOR AND AM BUILDING A CASE FOR MORE SEVERE HEADACHES WITH INCREASED DRIVING IN MY EXPLORER. TODAY, I DECIDED TO LOOK UNDER THE VEHICLE - I AM INCLUDING PHOTOS OF THE EXHAUST MANIFOLD WHICH SHOWS A CRACK NEAR THE PIPE-TO-FLANGE CONNECTION. AND, NO, MY VEHICLE IS NOT A POLICE CRUISER AND IT DOES NOT HAVE AFTERMARKET PARTS INSTALLED. HOW MANY MORE COMPLAINTS DO YOU NEED? TSB 14-0130 IS FORD'S CHEAP ATTEMPT TO HIDE A VERY SERIOUS PROBLEM AND AVOID A COSTLY RECALL OF OVER 1 MILLION VEHICLES. THE EVIDENCE CONTINUES TO MOUNT, INJURIES HAVE OCCURRED, COUNTLESS EXPLORER OWNERS HAVE EXPENDED MUCH RESOURCES IN FILING COMPLAINTS, AND FORD SAYS, "THESE VEHICLES ARE SAFE. WE HAVE NOT FOUND A SAFETY ISSUE HERE". FORD HAS ISSUED TSBS WHICH DO NOT ADDRESS THE PROBLEM. THEIR LATEST INSULT TO OFFER TO "INSPECT AND REPAIR" REAR LIFT GATES AND DRAIN VALVES, AND REPROGRAM THE AIR CIRCULATION SYSTEM IS LAUGHABLE, NOTHING MORE THAN A DISTRACTION T
