NHTSA Complaint #11710002 — 2019 FORD F-150

10R80 ten speed automatic transmission first exhibited indications of failure 9/16/2020, Ford's response being reprogram PCM. Transmission has progressively declined in reliability complete with harsh shifts, jerking, erratic up and downshifts, suddenly reverting into neutral at highway speeds. Safety of self, wife and other family members imperiled due to the vehicle suddenly lurching, jerking, and slamming forward in an unsafe manner at highway speeds. Ford dealerships have reprogrammed the transmission PCM four times over several years with progressively worsening transmission functionality. Dealership service specialist has confirmed that the transmission failure is due to internal components with burnt fluid as a component. But, Ford will not allow them to open the transmission up, denied repeatedly by the manufacturer as the issue with this 10R80 transmission is widespread with thousands of complaints filed, sone with NHTSA and others online and with Ford Customer Service to no avail. Ford is denying this manufacturer's defective transmission to avoid financial liability likely in the multi million dollar range over a wide array of Ford products with this faulty transmission installed in them. During the four times that Ford dealerships have reprogrammed the transmission's computer at the behest and mandate of Ford Motor Company, this vehicle's transmission repair was covered by both the manufacturers warranty as well as a privately purchased Ford Extended Service Plan (Extra Care). Ford chose deny coverage under either warranty though it is warrantied under both plans explicitly. This failure can result in vehicular accidents because of transmission's erratic and flawed functionality. Stranded on an interstate highway due to this failure especially is dangerous and may leave the vehicle exposed to collision.
