The contact owns a 2024 Ford F-150. The contact stated that while driving uphill, the engine started overheating and an overheating oil warning light was illuminated. The contact was able to pull over and allow the engine to cool down. The contact stated that the overheating failure was consistent while driving uphill. Additionally, the contact stated that at very slow speeds, the transmission was shifting gears excessively quickly and repeatedly, causing the vehicle to accelerate or move sluggishly. The contact stated that the Forward Collision Avoidance Emergency Automatic Braking unexpectedly activated. The vehicle was taken to a dealer, but the technician stated that the vehicle was operating normally. The failure mileage was 7,962.

MY 2025 FORD F150 had 3 episodes of overheating which was transient. On evaluation by the dealership it was found to have a defective part in the cooling system which needed replacing and was covered by warranty but the part was back ordered National (they reported to me 150,000 replacement parts). It required 2 months of inoperability before the vehicle could be repaired and returned to me for safe operation. Given the Magnitude of failures I am hopeful this is being investigated. The model in question is a Ford F150 powerboost HEV. I am safe and no catastrophic failure occurred but Ford has denied reimbursement for the first week of a rental replacement. If a national recall is appropriate I would like others to be spared similar issues. The evaluation of the problem lead to ford recommending not driving the vehicle in the interim as a catastrophic failure was possible

The contact owns a 2015 Ford F-150. The contact stated that while driving at approximately 65 MPH, the transmission suddenly downshifted, causing the vehicle to abruptly stop in the middle of the road. During the failure, the wrench warning light illuminated, and the vehicle entered Limp mode. The vehicle was towed to the contact's residence, where a code reader retrieved a DTC indicating the torque converter was stuck in the off position. The vehicle was later towed to a local dealer, where the contact was informed that the transmission overheated and required replacement. The manufacturer was notified of the failure. The contact received a recall notification for the federal safety agency Campaign Number: 26V237000 (Power Train), which confirmed the VIN was included. The contact associated the failure with the recall. The failure mileage was 144,000.

On 10/13/2026, driving about 25 mph on a city street, my truck entered failsafe with no prior warning lamps or symptoms. The PCM cut most engine power, leaving no acceleration, and set P1285 (CHT Overtemp Sensed) and P1299 (CHT Overtemp Protection Active). The engine was not overheating; a $40 CHT sensor fixed it. Evidence: I watched live data on an Autel MaxiCheck MX808S-TS while driving during the events. CHT dropped to implausibly low values for brief moments, then immediately returned to normal values matching coolant temp. Coolant temp stayed normal throughout. Failsafe triggered on these momentary dropouts, never on an actual high reading. The PCM logic is unsafe: 1. A low-reading sensor dropout was reported as an overtemp. The PCM set two overtemp codes and no sensor circuit code. 2. It ignored contradicting data. CHT recovered instantly and matched normal coolant temp, yet the PCM acted on one momentary bad reading. 3. The response was disproportionate. A sensor glitch with normal coolant temp should set a check engine light and circuit code, not remove engine power while driving. 4. It creates a crash risk. Losing acceleration in city traffic, amid chimes and flashing warnings, left me unable to keep pace or maneuver and caused anxiety and distraction. 5. False overtemp codes mislead owners. A typical owner would likely need a tow and a costly cooling system diagnosis over a $40 sensor glitch. Even as a former mechanic, I spent hours chasing a nonexistent cooling problem. Not inspected by a dealer, manufacturer, police or insurance. I diagnosed it with live scan data and confirmed it by replacing the sensor. The original sensor is retained and available for inspection. I ask the federal safety agency to investigate the CHT failsafe strategy on Ford 2.7L EcoBoost engines: whether the PCM checks CHT plausibility against coolant temp before cutting power, and whether a single-sensor fault should ever remove engine power while driving.

The contact owns a 2021 Ford F-150. The contact stated that the LED daytime running lights was flashing quickly before burning out. The contact stated that while driving 30 MPH and then stopped at an intersection, another driver informed the contact that the passenger's side headlight was flashing quickly. The contact towed the vehicle to the residence. The vehicle was taken to the dealer, where the passenger's side headlight assembly was replaced under warranty. The dealer informed the contact that the driver's side headlight might fail as well. The contact stated that the failure also occurred on the driver's side. Upon inspection, the contact became aware of a burning plastic odor coming from the headlights. Upon researching the failure online, the contact learned that the failure resulted from the headlights overheating and melting. The manufacturer was notified of the recent failure but denied coverage because the vehicle had exceeded 100,000 miles. The dealer advised the contact to report the second failure to the federal safety agency Hotline. The failure mileage was approximately 99,000.

Daytime Running Light in the headlight assembly overheated and stopped working. Thousands of 2021-2023 F150 owners have had the same issue. This is clearly a mass scale manufacturer known defect and Ford already tried sending an update to lower the LED brightness but the issue still happens.

Known issues with design and life expectancy of the exhaust manifolds and bolts thousands of owners are replacing manifolds due to warping and shearing of bolts when exhaust overheats. I’m currently getting quotes to replace due to failure on a gently used truck. Failure happened during a highway trip of a couple hundred miles under no additional load.

While driving, my 2022 Ford F-150 equipped with the 2.7L EcoBoost experienced abnormal engine operation, a check-engine light, and reduced engine power. The unexpected reduction in available engine power created a safety concern because loss of acceleration or propulsion can be dangerous when merging, crossing traffic, passing, or traveling at highway speeds. The vehicle was inspected and diagnosed by an authorized Ford dealership. The PCM stored DTC P0332, Knock/Combustion Vibration Sensor “B” Circuit Low. The dealer performed Ford Pinpoint Test DG. Testing reportedly found no open circuit, short to ground, short to voltage, or intermittent circuit fault. The dealer determined that the knock-sensor assembly required replacement.The repair involves replacement of Ford knock-sensor assembly FT4Z-12A699-E, which contains both knock sensors. Access to the assembly requires extensive disassembly of engine fuel and cooling-system components. Ford’s service procedure includes removal of both direct-injection fuel rails, draining the cooling system, removal of the coolant pump, and removal of the coolant outlet connector.I am concerned about the possibility of coolant leakage or contamination affecting the knock-sensor assembly because of its location in relation to cooling-system components. I do not currently know whether coolant contamination caused this particular failure. I request that the federal safety agency investigate whether coolant leakage or contamination in this area contributes to premature knock-sensor failures on 2.7L EcoBoost engines. I have also identified another 2022 Ford F-150 with the 2.7L EcoBoost that was diagnosed by a Ford dealership with a similar knock-sensor circuit-low fault, P0327 also quoted replacement of the same FT4Z-12A699-E assembly. I request investigation knock-sensor failures on 2.7L EcoBoost F-150s, including Ford warranty/field data and whether coolant leakage or contamination contributes to failures capable of causing unexpected reduced engine powe
