Cylinder 2 had a stored code for misfire and oil and coolant mixture leaking from block. With the F150 raised up on the lift I removed the lower splash shields and continued inspection. Oil was found predominantly on passenger side with a mixture of oil and coolant leaking out drivers side. Using my lab scope I was able to locate the damage in the block. A large crack split down in a Y pattern. This split is located on cylinder #2 location. I would say #2 connecting rod has impacted block due to internal failure.

On a cold start, my truck will not go into first gear until the rpm-??s get from 1500-2000 and then it slams into first gear. Other times it won-??t have barely any power and will accelerate so slowly that I-??ve nearly missed getting in an accident more than a few times. Also, it will slam down into lower gears when down shifting. All of the problems listed above will cause my truck to violently shake to where it feels like I got hit.

I was driving at approximately 30 mph when the transmission's OSS (Output Speed sensor) suddenly malfunctioned, causing an unexpected downshift into first gear. This abrupt shift led to a loss of control, resulting in a harrowing collision with a tree. What I witnessed next is etched into my memory forever: a scene of blood, fluorescent white bone fragments, and shattered glass strewn all around. Bones were even protruding through my skin at various locations, including my wrists, forearms, legs, and ankles, not to mention the dislocated shoulders. Thankfully, there were no other individuals present at the scene; otherwise, the outcome could have been equally disastrous, if not fatal, for them. Astonishingly, there were no discernible warning signs such as unusual sounds or dashboard warning lights prior to this incident. Following the accident, my pickup truck was towed to Cedar Park Wrecker, only to be swiftly claimed by the insurance company and subsequently sent to auction within a matter of days.

Vehicle started to downshift while driving at highway speeds a few months ago. Also a loss of power and acceleration with instrument failure. Later learned this was a common problem with the 11-13 f-150s that Ford knows about. They did give everyone a 10 year, 150k warranty but my truck is just barely out being a 12 with 151k miles. I took it to dealer where it cost me around a $1000 to fix. Was told by service manager there were many more people with the same issue. The transmission leadframe assembly was bad in thousands of trucks. There is a back order of over 12000 of these parts I was told. I think there should be a recall on all of these transmissions and be fixed by Ford. Also, refunds for those of us who already paid out of pocket. Thank you for your attention in this matter.

vehicle died when driving (and has continued to die when driving). Seems to sputter as if downshifting and then totally stalls out, causing safety concern when driving in traffic and randomly dying. Luckily had somewhere to pull off of the road and not cause an accident. Have confirmed with auto repair shop that the main concern is the powertrain control module. Shop has been able to replicate this happening as they have driven it as well. No warning lamps/lights/etc present prior to this happening.

After 2 recalls and powertrain control module updates, the sudden downshift problems persist. I question that a software update can be a full repair if the source is the speed sensor in the transmission (this has been labeled as the source of the problem by Ford). The nthsa has said they are satisfied with the repair, is this because the "repair" prevents crashes and injury even though it does not present a solution to the real problem?
