Ford Recall 26S28 the federal safety agency Recall - 26V237 Dealership has run the update. 2 codes NOT LISTED by Ford (regarding the Lead Frame in which they have 4 listed), are not covered by Ford according to the mechanics. The Valve Body is part of the lead frame but not covered under recall?? They don’t want to replace the lead frame as required by this safety recall. They want to charge us to replace the valve body, within the lead frame. [XXX], [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I am submitting this complaint regarding Ford Recall 26S28 (the federal safety agency Recall 26V237). My truck exhibited the dangerous unintended downshift condition described in this recall for several weeks before the repair remedy became available. A few weeks weeks before April 27, 2026, the truck began unexpectedly downshifting from approximately 5th or 6th gear into a much lower gear while driving. Each event caused the truck to enter limp mode, illuminate the wrench light, display multiple warning lights, and shake violently. I had to pull off the road, shut the truck off, wait several minutes, and restart it before it would drive normally again. I immediately reported these incidents to Mike White Ford and was repeatedly told to monitor the vehicle because no recall remedy was available. I reported the issue again during an oil change on April 27, 2026. Driving home from that appointment (9 miles), the truck experienced two more unintended downshifts. We immediately called the dealership and were again told to continue monitoring it. The condition progressively worsened over the next several weeks. On May 31, 2026, the truck experienced six unintended downshifts in one day. After the final event, it became difficult to restart and the check engine light illuminated. By my June 8 appointment, the truck was stuck in permanent limp mode and had to be towed to the dealership. The service manager stated it was "unsafe to drive" and provided a loaner vehicle. The truck later stored DTC P0219 (Engine Overspeed) and P2112 (Throttle Actuator Control System-Stuck Closed). I estimate the unintended downshift occurred approximately 75 times before the truck became inoperable. I opened Ford case CXH08666656S0W4Q2 on July 21, 2026. I respectfully request that the federal safety agency review whether prolonged operation with this known recall condition, while owners awaited a repair remedy, may contribute to additional vehicle failures and increased safety risks.
Took my 2015 Ford F150 XLT 4X4 to Peoria Ford for safety recall, they requested 30000 mile maintenance. I agreed. Upon picking up vehicle service advisor informs me engine light was on, it was safe bring it back when I have more time. They had my vehicle from July 13, 915am till that July 15, 545pm, closing at 6pm. On the way home almost had an accident,truck still shifting down bad and powertrain light came on. Made it home tried calling, they were closed. Reported incident to BBB and Attornet General.
A very weird chirping noise; really bad when I start truck then it calms down but I can hear it while driving. I took it to my auto mechanic shop & they said both exhaust manifolds are warped & need replacing. I bought this truck January of 2020 & I’ve spent a small fortune on it. I owned a Chevrolet Silverado for 14 years & never had issues like this truck has had. After researching info it appears this is an ongoing issue with these trucks. Ford should be responsible!!
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 XXX. 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 [XXX] on advice from Keith, the Service Mgr. We know the recall is due in XXX. 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. We obviously don't want to do this since we believe the violent jarring and downshifting of the transmission caused by this MFG defect probably caused this and a lot more other problems. MFG Recall #26S28, the federal safety agency Recall# 26V237. I need to know when this recall remedy will be submitted and what are my rights to get this fixed?

The contact owns a 2015 Ford F-150. The contact stated that while driving at various speeds, the vehicle suddenly decelerated, the tires were dragging, and the engine temperature was high. The check engine warning light illuminated. The contact's father performed a diagnostic scan on the vehicle and retrieved a diagnostic trouble code indicating a PCM and engine cooling system failure. The vehicle was taken to the dealer, where the coolant hose was replaced, and coolant was added to the vehicle; however, the failure recurred while leaving the dealer 5 minutes later, and the vehicle failed to exceed 10 MPH. The vehicle was driven back to the dealer, and it was determined that the coolant temperature sensor had failed and needed to be replaced. The vehicle was not repaired. The contact stated that the failure might be related to the federal safety agency Campaign Number: 26V237000 (Power Train); however, the part to do the recall repair was not yet available. The manufacturer was not contacted. The failure mileage was unknown.
The contact owns a 2015 Ford F-150. The contact received notification of the federal safety agency Campaign Number: 26V237000 (POWER TRAIN); however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated that while driving approximately 60 MPH, the transmission failed to shift out of 5th gear, with the check engine warning light illuminated and the wrench warning light was activated. The vehicle was driven to the local dealer who diagnosed with leadframe failure. The vehicle was not yet repaired. The failure mileage was 183,000.
I was on the highway and my truck suddenly decreased speed rapidly. Luckily I was able to pull onto a side road and get to safety but it was extremely dangerous and scary situation. The dealer has confirmed the symptoms fit the issue with the recall. Since Ford does not have a fix for this solution yet until July 1 my vehicle is unable to be driven or repaired leaving me stranded without a vehicle. However, this is a very concerning safety issue and my family could have been severely impacted traveling on the highway.
The contact owns a . The check engine light illuminated, while driving, the vehicle shifted to a lower gear unexpectedly and the turbo began to make a noise., the RPM's rapidly increased. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unavailable.
Exhaust manifold bolt broke cause extra heat coming from that broken bolt cause the crank shaft position sensor wires to melt cause the vehicle to stall while driving down the road and it not to restart just cranks and throws the code for crank shaft position sensor
The truck often shifts from 6th gear down to 1st or second gear, sometimes at highway speeds and all warning light come on. It sometimes resolved itself upon starting it again, but seems to affect the throttle body. When the electrical system resets, you can hear a click from the throttle body indicating that the valve reset when the computer reset. We also have been affected by intense suffering from the transmission that started about the same time, around 2019 and just over 100,000 miles, after the warranty expired. Both the limp mode and shuddering seem to be results of the TRS signal. I have replaced the battery and throttle body (that repair was first suspected to be the sensor) at Lakeland Ford, then later at Midas in north Lakeland I had work done to the wheel mounts and other axle/wheel relate repairs. In total we have spent approximately $4000 on repairs caused by the improper TRS signal. In addition, we have had at least 4 near accidents caused by the faulty signature. I called Ford with no solution, such as a loaner very, for safety before the recall can be fixed.
Ford has acknowledged the defect (recall 26S28). · my truck experienced the dangerous downshift and wheel lockup. · Ford has no fix available until June 30th, leaving me without a safe vehicle. · Ford is refusing to provide a loaner or rental. The wheel locked on me and causing the vehicle to be uncontrollable, in wet condition. Causes a near fatal accident. I do have a dash Camera recording to prove my case.
"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.
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 the federal safety agency 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.
Was driving at 50mph on hiway, all the sudden truck has loss of power and engine shut off, coasted down to stop, put truck in par, stared the car and drove another 5 miles and same thing happened again. No warning lite, no error messages was present when shut off happened nor during OBS scan at later time was. When second shut off happened there was a shift down happened. Not sure if the transmission speed sensor has something to do with engine shut off.
While in 6th gear driving on the highway at 70 mph the truck downshifted to 3rd and drastically decelerated. When this happened the instrument display went from having all 6 gear numbers viable to only 1 - 3. It had to be put into Manual Mode and shifted into 6th manually. This happens twice in the same trip.
Truck started making a loud sound from engine compartment on startup after towing camper 150 miles. The sound started to get louder and started to notice exhaust smells in the cabin. I took the truck into dealer to find out that the exhaust manifolds were warped leaking on both sides of engine due to a stud being broken that holds the manifold in place the tech said it sounds like a diesel. The service advisor at the dealership said that it is a "common problem" on the 3.5L twin turbo engine. The cab of the truck fills with the exhaust fumes to the point where the driver gets headaches unless the windows are open. I asked if there was a recall on this problem and they said NO. The same manifolds was used for years on that motor, since then Ford redesigned the manifolds to use extra studs into the heads that are already there but now want the consumers to pay to install the new design to keep the fumes out of the cab. Looking online it seems to be a problem that the turbos are heating the manifolds to the point that they warp and snap the only stud used on the rear portion of manifolds for owners that tow with the truck (that has a tow package and rated at 12500 capacity) FYI I'm only towing 5000 pounds. My concerns are that the exhaust fumes can overcome the driver an cause them to pass out or become impaired by the carbon dioxide poisoning.

Problem: Engine unexpectedly goes to idle speed after accelerating up to highway speeds. Cruise control was not engaged at time of failure. This has happened three times, all after a cold start up, and all within 2 miles of home. The most recent occurrence being 6-19-25. At time of failure, multiple warning screens come up on the dash, including "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench). No check engine light comes on, and no error codes are set. Engine does not respond to accelerator pedal, engine will only idle roughly. When this occurs, the only remedy is to pull over to the side of the road, shut off the engine, then restart the vehicle. Each time this has happened, the engine starts and runs normally with all warning messages cleared from dash. Safety Concern: Unexpected loss of power can increase the likelihood of an accident, especially in heavy traffic. This truck is used frequently for towing, and an unexpected loss of power can create a loss of trailer control. Dealer Contact: Last September when this issue initially cropped up, the truck was taken to our Ford dealer for diagnosis. They kept the truck for approximately two weeks, driving it daily without having the issue reoccur. They performed diagnostics on electronic modules but found no concrete issue. Inspection: Truck has not been inspected by the manufacturer, only the dealer. Warning Lamps and Messages: "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench)
Truck is at 135,000 miles and needs its 3rd oil pan due to faulty engineering. Ford is not covering repairs or offering assistance for previously repaired products. I bought truck certified pre-owned with extended warranty. The oil pan was cracked at that time and needed to be replaced at first service. On average oil pans are lasting less then 70,000 miles. How is this allowed to continue to occur.
Intake manifold actuator fails prematurely. Code P2007 and P2005
The contact owns a 2015 Ford F-150. The contact stated that while driving in cold weather and attempting to depress the brake pedal, there was a rattling sound coming from the engine. The contact stated that the check engine warning light was illuminated. A dealer was contacted. The vehicle was taken to a dealer where it was diagnosed and determined that the rattling sound was coming from the cam phasers and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The contact was transferred to the federal safety agency Hotline to report the failure. The approximate failure mileage was 116,000.
Truck down shifts hard while driving. Hill assist warning light comes on and truck goes into limp mode and looses power going 60 mph. Pull over truck runs very rough. Turn truck off and back on screen says hill assist not available. Press ok and truck runs normal again. Happens every few days. Definitely could be dangerous if it happens on a bigger highway. Has happened 5 times over last few weeks at different speeds.
