2017 Ford F-150 problems

“The contact owns a 2017 Ford F-150. The contact stated that while driving at 55 MPH, the check engine warning light illuminated, and the transmission unexpectedly downshifted. The dealer was contacted and made aware of the failure. The vehicle was taken to the dealer, where DTC: P0715 was retrieved. The contact was informed that the recall repair could not be completed without additional fault codes. The contact was advised to contact the NHTSA Hotline to report the failure. The contact stated that the failure was persistent. The contact received notification of NHTSA Campaign Number: 26V237000 (Power Train); however, the part to do the recall repair was unavailable. The manufacturer was contacted and made aware of the failure. The failure mileage was approximately 59,060.”

“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…”

“Vehicle failed Pennsylvania state safety inspection due to structural rust holes and perforation in the high-strength steel frame rails. The vehicle has only 40,000 miles and has been safely operated, indicating premature structural metallurgy failure."”

“Transmission range and output sensors failed inside the molded leadframe, triggering P0720 and P0722. Ford program 26N04 denied coverage because the codes were not on the approved list. The violent downshifting in my truck has made it undriveable and I am unable to go to work and I am being treated horribly.”

“I am filing this complaint because a Ford-authorized dealership, West Hills Ford in Bremerton, Washington, returned my vehicle to me in an unsafe condition after performing a repair under federal safety recall 25S37 (NHTSA Campaign 25V-236, brake master cylinder), and because an independent inspection has since documented physical evidence of a real defect connected to that repair. Please see attached documents outlining this entire incident as well as supporting documentation.”

“The contact owns a 2017 Ford F-150. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with cam phaser failure. The contact was informed that the cam phaser needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 106,000.”
