Owner reports

Selected complaints filed with NHTSA by 2012 Ford F-150 owners, lightly cleaned up (personal details are redacted by NHTSA).

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. …

While driving at approximately 60mph my vehicle shifted into first gear and aggressively skidded into oncoming traffic with my wife and two daughters in the truck. After regaining control, I drove it to my residence where the issue was repeated two times at slower speeds. After calling my local Ford dealership, they stated that there were two open recalls relating to the issue, 19S07 relating to the PCM and 19N01 relating to the leadframe. Apparently the two issues have resulted in many crashes and multiple fatalities. 19S01 was completed on my vehicle in 2019, however they did not mention or fix the leadframe issues in 19N01 despite it already being an open recall with national attention. I did not receive a recall letter or notification despite the serious nature of the issue. …

Vehicle shifts from a high gear to a low gear. While driving 60 miles an hour on the expressway my F150 went from six gear to first gear with no warning locking my rear wheels causing my speed to drastically or abruptly be lower almost causing several other vehicles to crash into the back of my pick up. Vehicle stays on gear sometimes first third or fifth gear with no warning switching back-and-forth. While making a stop at 0 mph vehicle stays at a high gear for example he could stay at third gear or fifth gear so they takeoff will be in third or fifth gear not in first gear . Also losing speedometer reading. This has happened multiple times while driving at low speed or high speed. I am concerned that this could cause accidents in the roads. Ford motor company corporate advised me that is an auto pocket fix sensor customer satisfaction program has expired for my vehicle. …

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. …

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. …

While driving down the highway, a wrench appeared on the display, then the speedometer went down to zero and the truck wasn't shifting or accelerating. I took it to the Ford dealership and the diagnosed it as an issue with the Leadframe sensor assembly. They also let me know this is a known issue and there was an extended warranty program that my vehicle is over mileage for. The repair cost estimate was $800 for parts/labor. They also stated that the part is on back order and may be a month before they could get it. When I asked about driving with the issue they said it won't do damage to my transmission but may intermittently cause shifting issues and could result in loss of reverse. I don't feel comfortable driving it like that but it is my only vehicle. I also contact Ford customer care directly but there was nothing they could do to assist and pointed me here.
