POWER TRAIN
I was driving and came to a stop at a light, let off the brake and then my truck came up with a wrench light and wouldn’t read the transmission gear, cab tool pulled these codes u0402, p0706, p0707, p1702, p1921 all pointing at towards the 6R80 transmission for this lead frame/sensor failure. It will work after the truck sits off for a little while but once you start driving for a few miles it goes back into limp mode. I’ve seen you are looking into this as a recall an would love to see others get help with this issue before it’s to late like me now unfortunately

Hard Shifting, will enter limp mode in 2nd and 4th gear (usually will down shift to that gear). The check engine light will flash and I have to pull over, stop, shut off my vehicle and then restart it to resolve. I have already spent roughly $4,000 in repairs and still have continued issues. These issues started at approximately 100,000 miles, transmission was rebuilt at 110,000. The current mileage is 139,400.

Molded lead frame sudden downshifts to first third or fifth gear would have to pull over to the side of the road/highway and shut the truck off and restart it to get it to go away it went from happening every 50-75 miles to the point where it would happen every 1-5 miles or less when it would down shift to first gear it would lock the rear wheels and almost caused me to get in multiple accidents happened right after I bought the truck 1/27/26 all the way until 3/02/26 when I was forced to get it fixed so I could drive the truck properly

VEHICLE SPEED CONTROL, POWER TRAIN, ENGINE
"My 2015 Ford F-150 is experiencing an intermittent, complete loss of the Output Shaft Speed (OSS) signal within the 6R80 transmission lead frame. While driving at speed, the speedometer suddenly drops to zero, the 'wrench' light illuminates, and the vehicle performs an unintended, harsh downshift into a lower gear (Limp Mode/3rd gear). This creates an immediate safety hazard of rear-wheel lockup or a sudden loss of acceleration in traffic. i took my vehicle to a local repair shop where they could not duplicate the fault. i then called my local ford dealer who informed me unless it would duplicate the fault or show a code they could not repair the vehicle due to it being against warranty policy.

UNKNOWN OR OTHER
Door Latches freeze in cold temps and prevent my doors from latching closed. I held an extended warranty on my vehicle and reported to my local dealership, but they would not repair since I could not replicate the issue after the fact. The newer models of my vehicle have this listed as a recall item, but they fail to recognize that the same thing is happening to my vehicle.

The contact owns a 2015 Ford F-150. The contact stated that while driving at 30 MPH, the transmission unexpectedly downshifted to first gear. The contact stated that occasionally the transmission unexpectedly upshifted to 3rd gear and seized. The contact stated that the failure was intermittent but became a recurring failure. The contact stated that the WRENCH symbol was intermittently illuminated. The contact had taken the vehicle to an independent mechanic, who diagnosed the vehicle and determined that the molded leadframe on the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 131,000.

POWER TRAIN
While driving on the highway at approximately 70 mph, the vehicle unexpectedly downshifted without any prior warning or indication of an issue. This sudden loss of speed created a hazardous situation, as the vehicle travelling behind me was forced to swerve quickly to avoid a rear-end collision. Immediately following this, the check engine light illuminated. From that point forward, the transmission would not shift below 3rd gear for the remainder of my commute. This significantly impacted the drivability of the vehicle and made continued driving concerning, particularly in traffic conditions. After arriving at my work, I retrieved the diagnostic trouble code, which was identified as P0721 (Output Shaft Speed Sensor). Notably, there were no prior warning signs, drivability issues, or alerts indicating a potentail failure before this incident occurred. Given the sudden and unpredictable nature of this event, especially at highway speeds, I am concerned about the safety implications of this issue. A failure of this kind, without warning, creates a substantial risk not only to the driver but also to surrounding traffic.

VISIBILITY/WIPER
Wipers failed to operate normally while driving. Wiper started moving very slow then stopped moving even with wet windshield. Upon research the problem was a seized passenger side pivot in the wiper linkage that required replacement of the Wiper Linkage assembly. No warning or noticeable problems until this occurred and vehicle was difficult to operate in rainy conditions.

While driving at highway speed (60mph), the truck suddenly downshifted to 1st gear causing the rear wheels to lock up until the vehicle slowed to roughly 45mph. At the time of the incident, the truck was not loaded, not towing and weather conditions were cool and dry. Since that incident, the truck hunts for gears, shifts erratically and harshly and will occasionally get stuck in a random gear.

There is an investigation currently, but it is when the transmission is going from higher gear and shifting to lower gears/locking the rear wheels unexpectedly. It actually shut my truck off when it happened and I had codes PO706, and PO707 displaying that I had an issues with my transmission range sensor. At the time my truck only had 108,000 miles. I had to replace the entire lead frame in order to get the issue fixed, and was informed by Ford when I asked them about it that no recalls or issues had been reported.

ENGINE
The vehicle’s original engine began producing excessive white smoke during startup. The vehicle was diagnosed by AutoNation Ford, and it was determined that the passenger-side cylinder head was cracked near the exhaust port. This defect allowed coolant to intrude into the passenger-side turbocharger. Due to the extent of the damage, the engine required full replacement. The engine was replaced with a used motor under a third-party warranty on August 21, 2024. The replacement engine is now experiencing the exact same failure symptoms. Specifically, the vehicle produces white smoke at startup consistent with coolant intrusion. Bozard Ford performed a diagnostic evaluation, completed on February 27, 2026. Their findings determined that the replacement engine has the identical defect: a cracked passenger-side cylinder head near the exhaust port allowing coolant intrusion into the turbocharger. This repeated failure raises significant safety concerns. Coolant intrusion into the turbocharger and combustion chamber may lead to engine misfire, loss of power, potential engine damage while driving, and possible sudden engine failure. Additionally, burning coolant may damage emissions components and create hazardous driving conditions due to reduced visibility from exhaust smoke. The fact that two separate engines in the same vehicle have experienced the exact same cylinder head failure suggests a potential design or manufacturing defect specific to the 2.7L EcoBoost engine. I respectfully request that NHTSA investigate this issue to determine whether this is a broader safety-related defect affecting other 2015 Ford F-150 vehicles equipped with the 2.7L EcoBoost engine. Please let me know if additional documentation, repair records, or diagnostic reports are required.

My vehicle, a 2015 Ford F150. XLT 3.5 Ecoboost 4x4 SuperCrew has been downshifting intermittently while under load. This has almost caused me to wreck my truck as it has gone from 5th gear at 65 mph to suddenly 1st gear causing the rear drive axle to lock up momentarily on the freeway. This has also happened while accelerating onto the freeway where it will go from 3rd or 4th gear under hard acceleration to suddenly slam back into 1st gear. After this happens it will almost always go back to 3rd gear and will not shift up or down. The only solution I’ve found is to pull over, turn the truck off, remove the key and restart the truck. It will then drive normal for some time until it happens again. I was told by Ford that” oh yeah, it’s your transmission lead frame/ output speed sensor”. If Ford knows about this safety issue, why are they not fixing it on their dime. This is obviously a known issue, but I guess some people will have to lose their lives before Ford will fix this.
