My truck is doing exactly what the recall on all the others. Check engine light on for input shaft speed sensor. Speed odometer quit working then engine light came on for speed sensor. Now when you drive on highway it will be fine then all of a sudden throw a wrench light and truck goes into limp mode and barely moves. You stop turn it off it resets but still isn-??t right it doesn-??t seem to shift at proper times seems to be shifting to often.

Bought a used truck. That needed timing chain and cam phasers a week after I bought it from a Chevy dealer. They sent me to Ford dealer it cost $2800 a week later it did the same thing. I was out of town and could not get back in the month. So when I got back they scanned again and charged me again. Then told me it needs a new engine. So I contacted Ford customer service and they said nothing they can do. I owe $10,000 and they want $11,000 for an engine. I have had the truck for a year but it all started in first week of buying truck.

The below was sent to me, It is difficult for me to understand why I was not told the recall expired in 2016 when I made the appointment (6-6-23) and when I handed my property over (6-12-23) to this dealership. Thank you for the diagnostic, it was very helpful, but, I still run the danger of crashing due to my breaks not pressing down when the pump goes out and the option to get FORD to fix it expired in 2016, My VIN is registered and I did not get a notice, I would gladly give this shop the $$ to fix the 2016 recall that expired. Now, that business will go to your competitor. If you were not aware of the expiration, I get that, but, you are a shop specifically designed for my Ford, again, thank you for the diagnostic but the way it was done I can't trust this shop or get other females to come there. Keep Jeff, do not run him off, his soul and manners feel safe and trusting, he treated me very well and I know he did what he was told to do by whoever was in charge. There is no need to contact me moving forward, but, this very email will be submitted to all the proper authorities (NHTSA.GOV, FTC.GOV, FORD.COM) when I hold FORD and others accountable. I work very hard for the life I have grown accustomed to.

While driving, the transmission will randomly down shift into 1st gear and the speedometer will die. The truck flashes a -??wrench-?? icon. There is no pattern, the issue is intermittent. When the speedometer dies, the transmission will only shift in -??manual-?? mode, but will not shift above 3rd gear. The check engine light illuminates and throws codes P0720 and P0722. This indicates an output speed shaft sensor failure. Ford released a Customer Satisfaction Program 19N01 for this issue and offers full repairs. However the repairs were only valid if the truck was less than 10 years old or less than 150,000. My truck is now 11 years old (the issue first was present in May 2022) but I only have 73,000 miles. Ford is unwilling to help because I am outside the warranty by a few months. This is a definite safety concern because I-??ve been driving on the freeway at 75 MPH in 6th gear only for the transmission to downshift to 1st gear, which causes a violent skid and potential rollover and accident. I live in a severe wintery area, and this issue makes the truck undriveable in the snow and ice. I would like for Ford to run a diagnostic scan, and replace the required components based off their previous CSP. Or, consider this a safety recall and allow me to trade my truck in with no penalties.
