i dropped my ford truck off for a recall that was done only three months ago and it had an extended warranty (Recall campaign number 19S07/19V075 sudden downshift powertrian control module programming) with it but it didnt fix the problem. when i picked up my truck after them keeping it for two weeks and telling me they had no loaners, they tried to say nothing was wrong with my truck and tried to charge me a $169 diagnostic fee and never even fixed the recalled downshifting transmission problem. But when I am driving it will just downshift almost causing the truck to jerk rapidly to a complete stop. This has almost caused an accident and ford wouldn-??t even try to fix it and because I refused to pay for a service I did not request they told me to never come back. My appointment was made online and clearly stated the info about the recall repair not being done right on July 12th 2025. So now I don-??t know how to rectify this transmission problem

Driving along I-94, 2012 F150 downshifted immediately from 5 gear to 1 gear. There was no previous issues and no warning lights and codes. Caused significant drive issues and had to pull immediately to side of busy highway. Caused immediately backup and believed to have caused back up accident. After taking to dealership was told it was my Molded Lead Frame. Which had been under an extended warranty BUT since my vehicle is older than 10 years and over 150,000 it is not under warranty. Ford knows about the issued due to the extended warranty issued. However, that warranty still is not effective in taking a MAJOR defect off the roads.

Wrench icon came on, truck wouldn-??t shift out of first gear, speedometer and mileage stopped working. Lead Frame recall according to my mechanic, $2,000 fix out of pocket. Truck only has 140,000 miles but is a 2012 so Ford says I-??m outside of the free recall replacement. Had no problems at all until over 135,000 miles, ridiculous that this is paid out of pocket when issues don-??t arise until after the approved date

When I was driving on the highway I was going about 65 mph in 6th gear and then without warning my 2012 Ford f150 3.5 truck shifted all the way down to 1st gear which almost caused me to wreck on the highway and other cars to almost slam into me. Now when I try to drive the truck it keeps throwing a wrench and the wrench blinks and my truck will not shift hardly at all between the gears. After I have researched this issue I see that there has been 4 recalls and a few CSP notices for the make and modle of my truck. The recall numbers are #19V075000, 12V190000, 16V248000, 12V198000 and the CSP campaign number is #16N02 regarding the lead frame issue that causes the extreme downshift. I contact the ford dealership to try and get this fixed and they said there is nothing they can do to help me.

While driving, wrench light comes on dash and I lose ability to accelerate. Have to turn truck off and on again to clear this problem but then it will continue to come back. Unsafe as it downshifts to first gear while driving. Doing research online, this is a common problem with Ford F150 and you issued campaign 19N01 in 2019 - Transmission Molded Leadframe Extended coverage. Problem is, this just started happening to my vehicle, and it looks like this extended warranty would have expired in 2022 or 2023. I purchased the truck used in 2020, but never knew about this. And since I wasn-??t having these issues till a few weeks ago, I would not have been covered. I am writing as there are numerous other drivers having this same issue now after the warranty expired, and are having to pay $1500-$4000 out of pocket to fix a known issue. This seems like it should be a recall fixed free of charge, no matter when it starts happening. Just because it happens now vs before 2022-2023 does not make the issue any less serious. This can still cause accidents. Is there any solution to having this covered by Ford" Can the campaign be extended or just be turned into a repair recall"

The cam phasers are in need of changing. Ford has acknowledged they are aware of the problems with the 3.5 Ecoboost engine but will not take responsibility and repair them. I definitely can not pay for this type of tepair

2012 f150 3. 5L Ecoboost engine. Had the all too well known rattle at start up because of failed to ing components/timing chain stretched. Repair cost me 5k dollars and failed AGAIN after only 4000 miles. Got code for timing being over-retarded. Took to dealer that initially did the job. Were supposed to repair at no cost to me, in my opinion anyway. Then they send me a video and tell me something else with the timing was the issue. When I called back to confirm, the story changed again that they never replaced the current failed part in the first place. All these engines have the same problem spanning numerous years and not my truck is being held hostage because they want another 15,000 from me for a new engine! 20,000 for a remanufactured engine is crazy! Please help owners and investigate this issue with Ford Ecoboost engines!

This truck is a safety hazard! The waterpump had to be replaced due to overheating, plus numerous other engine issues. it only has 137,000 miles on it But the REAL safety hazard is the power steering goes out at random times. and when this happens the dash goes blank. This has happened 4 times and each time we were lucky it was not on a busy highway, and close to home. The mechanic did everything he knew to do, and when we got it back....It did it again!!! Now, supposedly it is fixed, and we drove it home with no issues.....but...again, they are random, and I am scared to drive the truck. Will it take someone getting killed for this recall to happen? I have seen numerous post about this happening to others. I live on a winding back road, and if the power steering went out, I dont think it would end well. We are thinking of selling it, but I cant in my heart sell it to someone knowing these issues, and if we trade at a dealership, they will find numerous problems and never give us what it is worth, even though these problems are not from neglect

Driving at approximately 40-50 mph and it suddenly downshifted to 2nd gear, stopping the truck. This was the first time this happened. Recall 19s07 was performed on 05/03/2019 that supposedly fixed and prevented this from happening.
