The contact owns a 2012 Ford F-250. The contact stated that the vehicle was previously taken to an unknown dealer, where it was diagnosed with engine seizure due to coolant intrusion in the engine. The contact stated that while the dealer was in the process of replacing the engine, the dealer informed the contact that the transmission also needed to be replaced. The dealer replaced the engine and the transmission. The contact stated that while driving at various speeds, the vehicle was bucking and jerking. The gear shift indicator light displayed that the transmission was slipping from drive(D) to neutral(N) and reverse(R). The vehicle was taken to an independent mechanic, where it was diagnosed that the transmission needed to be replaced; however, the part was on back order. The vehicle was not repaired.

Very intermittently, when I brake this vehicle to bring it to a stop, the engine will start to rev uncontrollably. I have to practically "stand" on the brake to keep it from charging forward. I have to turn off the truck to stop this high speed revving. After this happened 3 times in 2 months we took it to the dealer to check. There was nothing on the floor that could cause the gas pedal to accelerate. The dealer in Kingwood, WV could not duplicate, and found nothing wrong when inspected. We only use the truck once or twice a month so it is a low use vehicle. For this reason the problem does not occur frequently enough to replicate "on demand". While there was not a crash, it almost revved through an intersection and almost ran into another vehicle. Fortunately I was able to throw it into park (Not Good for the vehicle) and then turn it off.

DRIVING DOWN INTERSTATE 85 AT 65MPH PASSING A VEHICLE AND ALL THE SUDDEN TRUCK STARTS TO VIOLENTLY SHAKE, MAKING IT NEARLY IMPOSSIBLE TO CONTROL UNTIL WE GOT BELOW 30 MPH. FELT AS IF TIRES WERE GOING TO FALL OFF OR WE WERE GOING TO LOOSE CONTROL.

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.

VEHICLE JUST HIT 75,500 MILES AND THE WATER PUMP BROKE. UPON FURTHER RESEARCH, I FOUND THAT THIS IS NOT AN UNCOMMON PROBLEM WITH THIS PARTICULAR TRUCK. CONSIDERING THAT I BOUGHT THIS VEHICLE FOR HAULING ANIMALS, THIS PUTS ME IN A BIND AND I AM LUCKY THAT SOMETHING DIDN'T GO WHILE ON THE TRIP TO PICK UP A HORSE THAT HAD TO BE CANCELLED FOR THIS WEEKEND. CONSIDERING THAT THIS SEEMS TO BE A COMMON ISSUE FOR TRUCKS THAT ARE SUPPOSED TO BE RELIABLE, I WOULD APPRECIATE IT IF SOMEONE WOULD LOOK INTO IT AS AN AREA TO BE ADDRESSED IN FUTURE PRODUCTION OF THESE VEHICLES AND POSSIBLY EXISTING VEHICLES AS WELL. SOME PEOPLE WHO HAVE HAD THEIR WATER PUMPS REPLACED WERE LUCKY ENOUGH TO HAVE IT FALL UNDER WARRANTY, HOWEVER SOME, LIKE MYSELF, ARE NOT THAT FORTUNATE AND HAVE A NICE, HEFTY BILL TO PAY FOR A RECURRENTLY FAULTY PRODUCT.
