NHTSA Complaint #10993095 — 2012 FORD F-250

EGT SENSOR FAULT RESULTED IN A "STOP SAFELY NOW" ALERT, SHUTDOWN OF POWER WHILE APPROACHING THE NECHES RIVER BRIDGE IN BEAUMONT, TX, A BRIDGE ON A 3-LANE INTERSTATE (I-10). ENGINE SUBSEQUENTLY SHUTDOWN WHILE IN HEAVY AFTERNOON WORK TRAFFIC CAUSING HIGH POTENTIAL FOR A MAJOR ACCIDENT. TRAFFIC BEHIND AND NEXT TO ME SWERVED AND BRAKED ON THE 75 MPH INTERSTATE WHILE THE TRUCK LOST POWER AS IT JUST MADE THE CREST. VEHICLE WAS TOWED. EGT WAS REPLACED. BANK 1, SENSOR 4. SECOND SUCH FAILURE. FIRST WAS IN AUGUST, 2015. REPLACED WITH AC3Z-5J213-B IN AUG, 2015 (THE CURRENT FAILED EGT). THIS TIME REPLACE WITH AC3Z-5J213-C, SEE PHOTO FOR DIFFERENCES IN SENSOR DESIGN. I HAVE READ RQ 14-005, VEHICLE COMMANDED ENGINE SHUTDOWN, AND CANNOT BELIEVE THIS TOPIC WAS REVISITED WITH NO ACTION RESULTING TO REQUIRE THE 15V-175 REMEDY REPROGRAMMING FOR NON-EMERGENCY VEHICLES. I ASK THE THE NHTSA REVISIT THIS TOPIC TO CONSIDER ALLOWING OWNERS TO HAVE THE SAME PCM CHANGE TO STOP A SINGLE EGT SENSOR FAULT TO RESULT IN AN IMMEDIATE LOSS OF VEHICLE POWER AND CAUSING HIGH POTENTIAL FOR INJURY TO THE PUBLIC. AS A MECHANICAL ENGINEER IN THE PETROCHEMICAL INDUSTRY, AND HAVING PARTICIPATED IN MANY HAZARDS ANALYSES OVER 20 YEARS, I STRUGGLE TO SEE THAT THE CONSEQUENCE OF CONTINUED USE WITH A BAD SENSOR FOR A LONGER PERIOD, BUT AT SOME REDUCED POWER, COULD EVER BE GREATER THE CHAOS, CONFUSION, AND HIGH INJURY POTENTIAL FROM PROMPT REMOVAL OF 70% VEHICLE POWER FROM THE DRIVER IN 45 SECONDS. TOWING A 5TH WHEEL TRAILER AND EXPERIENCING THE "STOP SAFELY NOW" POWER CUTOUT IS A RECIPE FOR DISASTER. THANK YOU FOR YOUR CONSIDERATION, AND I HOPE TO HEAR OF THE REOPENING OF INVESTIGATION ON THIS TOPIC AND ALLOWANCE TO REPROGRAM THE PCM.
