I noticed in the fall of 2024 that my transmission stared shifting hard between 30-40 mph during acceleration. I had the local Ford dealership check out the issue and they stated I needed a new transmission and included an estimate. I decided to seek information from 2 independent transmission shops and they could not confirm that I needed the transmission replaced at that time. The vehicle has been driving fine and I recently started to notice the hard shift again at 30 mph. Every once in a while, when the hard shift occurs, it seems like I lose power to the drive train and my vehicle slows down to about 15 mph and vehicles need to go around me. It only lasts for a few seconds and then the acceleration will continue to drive normal. I do notice an increase in RPM's from time to time as well while shifting around 30 mph but does not feel like it is slipping. …
In 2022, while behind the wheel of my 2015 F150, I would be driving down the highway (70+ mph) and the transmission would suddenly downshift to 1st gear, then jump to 3rd, and then back down to first gear, all over the place. This happened on several occasions. It was erratic, I experienced sudden changes in speed, sudden and frightening revving of the engine (especially on the highway) and on several occasions I had to make sudden changes to my driving to ensure my safety as well as the safety of others on the road. After I was able to pull over and turn my truck off, the truck would either not turn back on or take a while to be able to turn on. I had no warning that the transmission was about to shift gears and only noticed a check engine light after the incident had occurred. …
Just over a month ago, I had my local dealership's mobile service come to perform the covered warranty reset on the powertrain module. Last week, while driving apx 40mph, vehicle went into what I now know was "limp mode" 3 times within a few minute span -- felt like vehicle shifted into neutral, wrench light came on, but did not stay on for more than a few seconds. Had a diagnostic appointment yesterday, and was informed that the molded leadframe and oss sensor need replaced, at a cost of over $1600, including the $233 I paid for diagnostics. Today I found my letter from July regarding Customer Satisfaction Program 26N04. Everything in the letter matches my vehicle's issues, but I am being told by Ford that because my vehicle is not displaying the "correct" code per the service bulletin, it is not eligible for free warranty repair. How is it not eligible? …
The truck exhibited the abrupt downshifting upon driving out of the parking lot, this caused great stress and possible accidents to me and family. The transmission continued to get worse and we were in fear of our lives to drive the vehicle on the highway. Once we got the vehicle home it literally would not shift into gear and has been disabled since the first week in [redacted]. We are plumbing and heat contractors and have lost a great deal of business due to not having a truck/this truck to use for work. We had it towed to Greico Ford in [redacted] on advice from Keith, the Service Mgr. We know the recall is due in [redacted]. This dealership is now trying to tell us that all the hoses are damaged and wants to charge us $2,000 to repair the hoses. …
