When this happened there was no safe place to pull over and restart the vehicle. I have experienced this issue 3 times with my family in the vehicle. The issue may go away if the vehicle is turned off and on. This issue has occurred 3 times in the last 4 weeks (August 2021). The vehicle also seems to enter a low power or "limp mode". Fuel economy and other mileage related numbers are displayed as dashes (-). The mph will display zero (0) which can result in a random downshift to first gear even while driving at highway speeds of 65mph. A wrench icon and airbag light is displayed on the dash/instrument panel. While driving, the vehicles (2013 Ford f150) transmission will shift to 5th gear and may remain there or downshift to 1st gear when the mph reads zero (0). I feel as if I’m not the only one this has happened to. I would like to know why they didn’t replace the lead frame the first time if it is proven to work. I have read that Fords first remedy was to reprogram the pcm, but the real cause is the oss going bad and the real remedy is a replacement of the lead frame. This happened a month ago and they are still dragging their feet, leaving me with no vehicle and not a lot of options. The salvage title was present when they did the remedy in September but now it is an issue and to my understanding they cannot refuse to fix a recall because of a salvage or branded title. They have since been giving me the run around. They also claim that they can’t confirm that the transmission caused the engine to blow. The dealership says I need a new engine and refuses to fix the transmission because my truck has a salvage title. Because of the downshift the engine redlined causing the 8th valve to fail. The codes p0720, p0721 and p0722 have been present, and it hadn’t been to much of an issue until it downshifted to first gear while going 60+ mph, causing me to temporarily lose control. The output speed sensor has been failing multiple times since I had the recall remedied in September 2021. I am unsure if this warrants another recall however, it is my belief that it should be looked at again. This vehicle was also recalled for 19ns19 because of 6r80 transmission. The vehicle has not been inspected since the malfunction however, through research of TSB 19n01 and contacting the dealership, it was determined that the extended warranty did not apply due to the mileage exceeded the 150,000 therefore I ended up buying and fixing my own vehicle with current mileage of 163421. Sudden downshift can result into a rear end collision. Safety risk was the sudden down shift while going at normal speed or flow of traffic. Upon reading the code via the obd2 code reader, the following dtc were noted: p0720 output shaft speed sensor circuit p0722 output shaft speed sensor circuit no signal u0401:00-0b invalid data received from ecm/pcm a b00a0:68-8b - occupant classification system u0401:68-0b invalid data received from ecm/pcm a u0401:00-0a. Approximately 6,000 miles added from the mileage counter, the vehicle experienced sudden downshift with speedometer dropping to zero and passenger airbag caution illuminated on the dashboard. Mileage in was at 156877 and mileage out from the services was 156879. The failure mileage was 94,245.Ġ1 Apr 22, vehicle was received from penske Ford after coolant leak to include scheduled maintenance such as engine oil and filter change, engine air filter, transfer case fluid change, drive belt, front differential fluid change and lastly the transmission fluid and filter change. The contact researched online and related the failure to NHTSA campaign number: 19v075000 (power train). The manufacturer had been informed of the failure. The contact had taken the vehicle to a local dealer where it was diagnosed and determined that the power train control module (pcm) needed to be replaced. The contact stated the failure was intermittent but happened more frequently at various speeds. The contact pulled over off the roadway and shifted into park(p), turned off and restarted the vehicle, and the transmission regained normal functionality however, the check engine warning light remained illuminated. The contact stated that the check engine, wrench symbol, and air bag warning lights were illuminated. The contact stated while driving approximately 45 mph, the vehicle suddenly downshifted to second gear and immediately slowed to approximately 10 mph. ![]()
