Our 2012 Ford F-150 truck had no issues and no dashboard lights when it randomly downshifted while driving and almost caused an accident. On Sat, May 9, 2026, my husband pulled onto the road and got up to 40 mph when the speedometer stopped working and the truck randomly downshifted. The car behind us had to swerve to avoid a collision. On Mon, May 11, 2026 we called the Ford garage they told us the Customer Service Program (#19N01) is no longer valid as it is over 10 years now. The truck only has 128,000 miles and we were never notified of a CSP when we purchased it in 2020. The Ford Customer Service Representative said the CSP was issued in 2019 but we purchased the vehicle in 2020 and were never notified of an issue. I now have a $1,500 repair bill for the leadframe that Ford will not reimburse us for and also see that they still have NUMEROUS transmission and speed control issues with their vehicles. I opened a case with Ford on May 14, 2026 [XXX] ) but their representative Iomar was not helpful. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at any speed, 55 , 65 my truck downshift to 1st gear. It locks up the back tires and the truck starts squealing. And sometimes while driving it just jumps into limp mode into 3rd or 5th gear and it wont come out of 3rd or 5th gear. I do understand there is a recall for this but Ford is telling me my truck is not included in the recall.

The vehicle experienced repeated and unpredictable loss of drivability while in operation. The transmission intermittently disengages and the gear indicator rapidly cycles between Park, Reverse, Neutral, and Drive without driver input. During these events, the vehicle loses propulsion and becomes unsafe to operate in traffic. Warning messages and instrument cluster anomalies were observed prior to and during the failures, including erratic dashboard behavior. The issue has occurred multiple times and is reproducible. The condition appears to be related to a known safety recall involving the transmission lead frame / powertrain control system. The failure creates a serious safety risk due to sudden loss of power and inability to control vehicle movement, especially in traffic or while stopped at intersections. The vehicle is not safe to drive and has been removed from regular service. Diagnostic data, video evidence, and photographs documenting the failure and warning indicators are available upon request. The manufacturer has been notified and a recall case has been opened, but the defect has not yet been resolved. The vehicle remains unrepaired at the time of this report.

My truck started experiencing the notorious Ford "limp mode" needs lead frame replaced. Ford has a customer satisfaction program directly related to this issue but though its 20k under their 150k limit it is over 10 yrs old so they are not honoring anything or doing anything about covering and cost associated. Pretty crappy of ford.
