2024 Ford F-150 electrical system problems

“Re: Recurring Knock Sensor Failure — 2024 Ford F-150 STX (2.7L) I am writing to document a recurring mechanical issue with my 2024 Ford F-150 STX, 2.7L, currently at approximately 30,900 miles, purchased new. First Incident (late XXX): While driving, the check engine light illuminated, indicating a knock sensor fault. I brought the vehicle to Ted Britt Ford in [XXX], where it remained for five days for sensor replacement. I requested a loaner vehicle, which the dealership stated was unavailable, requiring me to rent a replacement vehicle at my own expense. Second Incident (XXX): Following a period of heavy rainfall, the check engine light returned with an identical knock sensor fault. The vehicle was again taken to the same dealership and held for five days for repair. When I again requested a loaner, I was informed one could not be provided because the vehicle was not originally purchased at that dealership. Rental Costs: Across both repairs, I have incurred rental vehicle expenses for a combined 10 days due to the dealership's lack of loaner availability. Suspected Root Cause: Based on the pattern of failures — particularly the correlation with heavy rain — I…”

“The contact owns a 2024 Ford F-150. The contact stated that following an unsuccessful Over-the-Air (OTA) software update, the display screen and instrument panel were constantly rebooting, with a loss of functionality for several electrical features. The vehicle was taken to a dealer, where technicians associated the failure with NHTSA Campaign Number: 26V104000 (Electrical System, Exterior Lighting). After several service repairs and the inclusion of a field service engineer, the vehicle remained unrepaired and had been with the dealer for over two months. The manufacturer was notified of the failure and provided the contact with a case number. The contact was not provided any status updates because the master technicians were on extended leave. The failure mileage was approximately 25,000.”

“Almost all functions connected to the steering column quit working. I do not have working turn signals, high beams or wipers, unless the wipers are on high. None of the functions on the steering wheel work. It seems like a safety issue to not have functioning turn signals or properly finctioning wipers and high beams. No lamps or warnings.”

“Vehicle was in Ford dealership’s service bay for an oil change service and reportedly caught fire inside the cab behind the dash due to an electrical system malfunction. The service technician stated that it was on the rack and just spontaneously caught fire inside the cab in the dash behind the infotainment system.”

“VIN # [XXX] Ford Customer Service Current Case Number: [XXX] Integrated Trailer Module Failure after recall completion. NHTSA Campaign ID Recall # 26C10 was completed at Coconut Point Ford in Florida on 3/26/2026. This recall identified that when towing a trailer, the integrated Trailer Module may lose communication with the trailer possibly causing a loss of brake and turn signal lights or a loss of brake function. On [XXX] in the middle of a seriously steep and dangerous decent, the system reported that the trailer was disconnected from the truck causing, loss of trailer brake control which in turn cause a reliance on the truck. The antilock brake system failed moments later. I had to literally stand on the brakes to slow down to keep from going over the side of the mountain. At the end of the dirt road where it Ts onto the highway we could not stop. We travel with a 23 foot 2019 Vintage Cruiser manufactured by Gulf Stream. That weighs approximately 5200 lbs empty; I have a Cat Scale reading of 4840 pounds from a 12/6/24 weight with my previous truck. We do not travel with any water in our Black, Grey or Fresh Water tanks so even fully loaded we are still…”

“2024 Ford F150 tremor 14,000 miles The gearshift modual locks into position and locks the transmission (light blinking and transmission light shows on dashboard) You cannot shift to park or start the car, it will do this in drive or reverse and locks the transmission. A hard reset does not solve the issue. The First time this happened l was with my wife and two young children in the mountains around 30miles from cell service. This is a major safety issue. The dealership cannot replicate it, and therefore wont replace it even though it is a known issue. tsb 26-2066 I do have a video of this happening. Fortunately the second time this happened I was close to home. The vehicle occasionally leaves us stranded due to an un-replicated transmission lock flaw.”
