My 2014 F150 was recalled for a software patch pertaining to the lead frame in the transmission because the vehicle would abruptly downshift at any speed. After having the recall performed by a dealership, it continued to have the same issue. I was told by the Service Manager the lead frame was bad but the recall did not cover the repair. For my safety I had the repair done and it cost me $1869.64. I contacted NHTSA and was told the dealership would have to contact Ford Motor Company for a warranty code to cover the cost of the repair. Ford Motor Company said the dealership should pay for the repair up front then get reimbursed by Ford Motor Company. The dealership said only NGTSA can include the lead frame in the recall so I was responsible for the cost of the repair. As of this date (1/7/2025), I'm still out $1859.64. I have the lead frame that was removed from the truck and there are no obvious defects (cracks, buildups, etc) so the issue has to be with the control mechanism within the lead frame that the software patch should have corrected. Why has the recall not been upgraded to include replacing the lead frame?

I was on the recall list and got my OSS sensor reprogrammed at a Ford dealership in August of 2024. November 6, 2024 I was driving down the FRWY at 65 miles an hour. There was a jolt and RPMS dropped to zero, speedometer dropped to zero yet truck was still traveling at a high rate of speed. My info area just gave blank dashes. It was like the things on my dashboard just stopped registering, and eventually a wrench flashed across the screen. My gas pedal was not responding, and I could not accelerate when I pressed the gas. Luckily I was able to coast off of the FRWY with emerg. flashers on without accident. I had to stop at a red light on service road and after stopping truck did not accelerate at light. I turned off the engine and restarted and was able to slowly accelerate at slow speed to make it home. -?'-?'-?'-?'-?'-?'The next morning I took the truck straight to the dealership (maxing at about 20mph- gas just wasn't accelerating like normal) and was told it needed replacement of the transmission electrical frame. I told them about the recall that I recently had reprogramed (august to November 6). The dealership claimed that the recall update and the transmission electrical frame failure was unrelated. They claimed that the transmission electrical frames commonly went out on these trucks and were a known problem but it hasn't been enough to produce a recall. I had to pay about 2k to get my truck fixed. The dealership said if there ever was a recall then I would be reimbursed for the part. -?'-?'-?'-?'-?'-?'What happened to me on that freeway of not being able to accelerate at all was very dangerous as I could not accelerate at all. It was not safe for me to continue on the freeway (or any road really) as my vehicle basically stalled out on me while driving and would not go at all until restarted. I'm very grateful that I was able to get out of that situation safely.

Driving at highway speed, went to accelerate and pass another vehicle on a four-lane highway with my vehicle ending up in the far left lane attempting to pass. Truck lost all power, began to shake violently like it was misfiring, got an illuminated wrench on my dashboard, and at that point began to coast with no power being supplied by the engine. Miraculously I was able to coast across three lanes of highway to the shoulder without being rear ended by traffic moving at 70 mph which would have resulted in a catastrophic accident (endangering myself and my family and others on the road that day). I shut the vehicle off to stop the engine from shaking and misfiring and let it sit about two minutes. I restarted the vehicle, the illuminated wrench went away and the truck idled as normal allowing me to drive another 25 highway miles to my home without incident. Had a mechanic put a diagnostic tool on my truck to see if any error codes were thrown from it which no codes were present. Have taken it to Ford dealership near my home, they have been trying replicate the condition for three days and have been unsuccessful. Their hunch is throttle body assembly needs to be replaced ($675 fix). Quick query of NHTSB reported incidents shows a growing quantifiable history for the Ford F150 3.5L Ecoboost experiencing the exact encounter I had on this day. My family and I along with others on the highway were fortunate the event didn't end up tragically that day. Ford - time to step up and rectify via recall.

I took my 2014 F150 in to Aaron Ford of Lake Elsinore on September 6th 2024 to repair a sudden downshift recall 24S37. The reason for taking the the truck in was because an event happened where I was on the freeway and the truck downshifted into a lower gear. I nearly lost control at that time. They informed me they made the recall repair and everything should work fine now. About a week later on [XXX] while traveling at about 60-70 miles per hour the truck experienced the exact same violent downshift event. This led me to believe the repair had not been made. I called the dealer back and they refused to take the car in for another review and since the recall had been "Completed" they tried to extort me by saying I had to pay the diagnosis fee to get it checked and no other dealer would help me since the repair was marked as "completed." All I ask is that Ford completes the repair as ordered by the NHTSA.

Sanderson Ford in Glendale has no ETA for the defect leadframe in my car. Right now I cant drive my car anymore because the check engine light came on with P0720 - speed sensor error code. When I entered the highway, my truck suddenly shifted from 3rd to 5th so I could not accelerate in a very busy intersection. This because the speed sensor failed. Sanderson Ford does not offer service soon because they dont have an eta for the leadframe. or a loaner vehicle until it can be fixed. What do I do now?

I received a recall letter 24V-444. My 2014 F-150 has repeatedly shown the symptoms described in the recall letter. Truck will downshift to 1st gear at various speeds, and the rear tires will slide when it occurs at a higher speed, and has done so on several occasions. On [XXX] I took vehicle to Auto Gallery Ford in Gaffney SC. They supposedly did the fix recommended. They told me to bring it back if it downshifted again. On the way home from the dealer, it downshifted again on the highway and almost caused an accident. I took the vehicle back and was told that Ford would not pay for the new part needed because a certain code was not showing up upon inspection, regardless of the fact that it has downshifted many times while I was driving. It is progressively getting worse and also showing an illuminated wrench symbol when the downshifting occurs. This is my only vehicle so I have to drive it in this unsafe condition.

I recently took my truck to the dealership for the 24S37 recall repair. Later that day, I received a call from the dealership informing me that my truck was ready for pickup. However, approximately 45 seconds after picking it up, I noticed that it was still shifting hard and felt like the transmission was dropping. I immediately contacted the dealership to report the issue. The dealership told me that I could bring the truck back in for another scan but mentioned that if the correct code appeared, I would have to pay for the repairs myself. I decided to take the truck home and parked it, hoping that more information about the recall would become available. Since then, I have called the dealership multiple times, left voice messages, and attempted to get in touch with the service manager, Jeff, but have found it nearly impossible to get a response. I scanned the codes on my truck and identified the following codes: P0715, P0717, and P0731. I am concerned that the recall repair was not completed properly or the initial recall caused that damage and that the issue persists. I am seeking your assistance in ensuring that this matter is resolved appropriately.

I was driving 70mph in the middle lane on the highway and all of a sudden it down shifted resulting in my rear end locking up. I had my three children in the vehicle and the truck gave me no warning signs. I was fishtailing and was extremely lucky we didn-??t crash and I was able to gain control of the vehicle again. I took it to the mechanics shop and they told me it was the p0720 output speed censor circuit malfunction and this was causing misfires in my engine as well in cylinder 7 because of the problem in my transmission. I haven-??t drove the truck since because I can-??t afford to fix a transmission and engine.

This truck has suffered all sorts of issues relating to the lead frame inside of the transmission. This lead frame houses the speed sensor, range sensor, and temperature sensor. With extensive repairs the issue keeps arising. Ive had 3 new Remanufactured transmissions installed im currently about 6,000 miles into my new transmission with the same issues. Erratic gear changes. Ex. 4th gear to 1st without warning. Loss of 1st,2nd and 6th gears. Becomes stuck in 5th. Just a random array it seems to be with this one almost everytime i cross the 130F degree trans fluid temp the problems start. I have done alot of research into this as i am a technician as well and the only thing i can come up with is bad part production for the sensors and lead frame.

When driving on the interstate the truck suddenly downshifted causing the tires to lock up and the vehicle to swerve out of control. There is already a recall for this issue for Lead Frame in 2011-2013 vehicles. The recall needs to be extended to the 2014 model vehicles as well.

My vehicle shows a wrench on the dashboard and loses power and will not accelerate. We took it to an auto parts store to have a diagnostic test performed and it shows that the OSS ( Output Shaft Speed Sensor Circuit) fault. In my 2014, this is inside the transmission. After doing research, I found this was recalled in 2009 to 2013 models. Could this be an issue in my 2014?

Spontaneous downshifting of transmission to first gear has occurred more than once resulting in sudden change in speed, tires screeching, and unsafe driving or difficulty controlling automobile. Fortunately no one was behind me as I would likely have been rear ended. Each time this has happened the motor has been subjected to heavy strain.

2014 F-150 has issues with shifting while driving and losing voltage to the transmission lead frame. Safety issue for driving and changing to incorrect gears. When stationary in park, the truck will not start due to loss of voltage and parking sensor issues. Odometer display shows wrench icon shows while driving. Error codes P0706 and P0707 codes show up while driving. Ford dealership has done diagnostics and has determined the problem is the Transmission Molded Lead Frame Electrical Failure. They have reported that this is a common issue.

About 3 weeks ago, I started having issues with the truck where the tachometer would jump to redline at the same time the speedometer would drop to 0 driving at 30-40 MPH. The rear wheels locked up twice. This has happened 3 more times since it started 3 weeks ago. The code that came up on the truck was P0720, which is the output speed sensor. Ford issued a recall on 2011-2013 year models for the exact same issue. Mine is a 2014 model with the same exact transmission (6R80) having the exact same problem as the recall models. Luckily the issue hasn't caused an accident for me. That of course can change if it happens again before I am able to get it repaired. Today when it happened I was on the highway driving 65-70 MPH fortunately the rear wheels did not lock up. A wrench symbol appears on the odometer which is "LIMP MODE" and began decelerating on a highway with moderate traffic that could've caused an accident because I couldn't accelerate. I have 30 plus years of driving experience. This situation is very dangerous especially for inexperienced drivers even worse with drivers being distracted with their phones these days.

This make and model is having the exact same 6 speed transmission issues as earlier recalls. The final straw was when the truck failed to register the speed and slowly crept into oncoming traffic at night, while I turned left. It bucks and shifts hard at neighborhood and highway speeds. More often than not, it is a down speed shift and aggressive, whiplash buck. I lose control of the vehicle and the speedometer goes to 0 even at highway speeds. I called into the hotline and made a case- Case ID 11514803 but I haven't heard anything. That replacement part is on back order for a year + so my truck is unsafe and inoperable.
