2017 Ford F-150 electrical problems

Filed Oct 31, 2026 · Electrical · MS

Recall 26N04. Ford intentionally set only 4 qualifying diagnostic codes for free defect repair. Codes 0720 and Codes 0722 were intentionally omitted even though same root cause. My 2nd complaint. Astro Ford in D’Iberville, MS and Ford charging me $2300 for this. I coded 0720 and 0722. It does not appear the federal safety agency or anyone can or is even willing to help. I find it disgusting Ford can get away with this. No way to work, missing income and now I must lay $2300. Nobody is looking out for me or folks like me with this BS Ford recall.

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.

My 2017 Ford F-150 with SYNC 3 (software version 3.0, build 23219, the latest version Ford offers for this vehicle) has a recurring defect with hands-free phone calls. When a call comes in while my phone ([XXX]) is connected through Android Auto, the call displays as connected but there is no audio in either direction — I cannot hear the caller and the caller cannot hear me. Outgoing calls work normally. Ford's published workaround for this known defect is a setting ("Use Phone Ringtone"), but on my vehicle the setting will not stay selected — it reverts to the default every time the phone disconnects or the vehicle is shut off, so the failure returns on every trip. Ford fixed this defect in its newer SYNC 3.4 software, but has never made 3.4 available for 2017 vehicles, leaving no remedy. The truck is already on the final 3.0 build. This is a safety issue. Washington law prohibits holding a phone while driving, so a failed hands-free call pressures the driver to pick up and handle the phone. The vehicle's [XXX] Assist emergency feature also depends on SYNC maintaining a working phone connection, which this defect defeats. The failure has occurred repeatedly since I got the truck last year and is ongoing INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I am reporting a potential safety defect involving the hood latch sensor or electrical system on my 2017 Ford F-150, currently at 151,895 miles. On three occasions (10/3/26, 10/4/26, and 10/7/26), the "Hood Ajar" warning appeared while driving, accompanied by an audible chime, although the hood appeared securely closed. The message remains displayed until I press OK on the steering wheel. 10/3/26: The warning activated while driving. I safely pulled over, released the hood latch, inspected the hood, and closed it again. The hood had appeared properly secured. 10/4/26: The warning activated while I was descending a steep hill with no shoulder or safe place to stop. Concerned the hood could open and obstruct my windshield, I had to continue driving until reaching the bottom of the hill and finding a turnoff. Upon inspection, the hood was completely closed. 10/7/26: The warning activated again. Because the previous two inspections showed the hood was closed, I dismissed the warning without stopping. This demonstrates how repeated false warnings can cause drivers to disregard a potentially legitimate safety alert. The security alarm also intermittently activates while parked, sounding the horn and flashing the lights without an apparent cause. These malfunctions create safety concerns, including driver distraction, potentially dangerous roadside stops, and the risk that drivers may ignore a legitimate warning about an unsecured hood. My experience descending a steep hill without a safe stopping location demonstrates the hazard. The exact cause is unknown. A defective hood latch sensor, switch, or wiring is suspected. No dealership or mechanic has inspected the vehicle. The components remain installed and are available for inspection. I request that the federal safety agency investigate whether this is a recurring safety-related defect affecting Ford F-150 vehicles and whether corrective action or a recall is warranted.

After a big freeze my fuel level gauge stopped working. I have replaced every sensor and fuse possible, along with multiple new fuel pumps. It has been taken to a certified Ford Dealership and they can’t find the problem. There is a Ford recall that already explains the problem exactly. It is Ford 26C26. I am not able to get my vehicle inspected and without knowing exactly what my fuel level is it could leave me stranded.

This lead frame issue is never ending. Well over a decade without a proper remedy. I’m very familiar with it. but this one nearly ended my life. After the near collision I called my mechanic and bought a new ford lead frame from a dealership. It’s doing fine now, it’s been 1 year. the incident caused my truck to go into park or possibly reverse at highway speed just as I passed a semi truck and returned to the right lane. If the trucker had not been paying attention it would have been bad. There was nothing I could do. . On top of this, he was under the impression that it was intentional. So I almost got into a physical altercation until I convinced him to look inside my truck as my gear indicator light was dancing from gear to gear while not touching anything.. To add to the seriousness, my taillamps never came on because I didn’t touch the brake. It was a horrible timing.. . Shortly after this i received a notice from Ford explaining the cause and symptoms of this issue, but then stated there was no fix at the time, but the vehicle was “safe to drive.” That is irresponsible. This was the only time mine did it, no prior issues. I got new ford parts and had it replaced. my mechanic said they deal with this weekly! Then I get a letter from Ford saying there is a fix and it’s a computer programming issue which is totally not true. That’s just a smoke screen, but it also goes on to say it could be a lead frame and if you’ve already fixed it before you got a letter, they will refund your money, but I highly doubt that. But they should stop claiming these vehicles are safe to drive because they absolutely are not if they’re having an issue regarding recall 26S28. So not only did i use new Ford parts, I paid a reputable EX Ford Technician Who owns his own business to perform the services because ford didn’t offer a fix. only to waste my time reprogramming the ecm. I work, I don’t have time.It’s irresponsible to say it’s not a safety concern. It’s just bad policy

Short in the rear window defroster. Within 5 minutes of turning off the defroster after only having it on for 2 minutes at 2:30am leaving work, the back window exploded outward and shattering. No rocks, no other folks on the road. Upon research, and after contacting insurance company and the glass repair company, this is a very common issue in 2015-2019 F-150s. But there are no safety recalls. Praise God my children were not in the backseat, they would have been riddled with glass. How is this not a safety issue?
