Ford F-150 owners have reported 6 problems related to trunk wiring (under the electrical system category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Ford F-150 based on all problems reported for the F-150.
Ford eliminated the engine cover in 2019 exposing the engine wiring to the elements. Since the wiring insulation is made from soy this allow for rodents to clime up into the engine compartment and chew at the exposed wires. This can disables the vehicle or set a vehicle engine lights at the owners expense. In my case the vehicle lost power on the freeway and I had several lights come on. The top speed dropped from 70mph to 23mph. Brighton Ford did repair the vehicle at my expense. Going forward even though the repair has put the vehicle back on the road, the potential problem still exist. Ford customer care said there is no solution available to this problem I have opened a case but I don't believe anyone is looking at it. I also check 2021 vehicles and it has the same issue.

On the morning of March 5th 2015 I started my truck to warm the inside and also melt the snow off my windshield. I got in the truck and backed out away from house. Due to having snow on the driveway I turned on the 4 wheel drive in high. My four wheel drive would not work so I tried to swicth to 2 wheel drive back to four wheel drive but the 4 wheel drive would not turn on. I grabbed the gear shift to put the truck back in park when I noticed my gear shift could float to park to 1st gear freely and would not shift. At this time I noticed smoke starting to come inside cab from under dash and thru the vents. I jumped out and opened the hood. A 1 foot section of a wiring harnes mounted to the firewall had caught fire. I made attempts to put out the fire but within a few seconds the engine compartment was engulfed. In 2 to 3 minutes the entire inside of the cab was also completely on fire. My wife who was watching me immediatly called 911 to get the fire department. After 3 minutes the truck was already a total lose. Due to the truck being only 60' from my house and burning so hot I was concerned about my house catching fire. Two gentleman from the rescue squad arrived but it was too late for anything to be done. I was able to get a backhoe and put the fire out with snow. Unfortunately I had liability insurance only which meant a total lose. I never dreamed that the truck would burn up sitting in my driveway!!!! I know there have been some recalls for f150 due to fire hazards with the cruise control for other year model close to 2005. A vehicle catching fire while its sitting in a driveway running is totally unacceptable. The truck was in excellent shape and had no after market parts or work performed. I have no ideal why the wiring harness caught fire.

2008 f150 supercrew lariat 4x4 bought brand new on July 18 with 426 miles on it. I have made no modifications to the truck except put a flat bed cap on the bed that attaches with clamps under the bed rail and has no electrical components. I have driven the truck less than 2500 miles. On the morning of the incident I drove to work just minutes away from home. Parked truck and locked vehicle and went into factory to my office. 35-40 minutes later I received a call on my phone from the guard building saying my truck was on fire. I walked back out to the parking lot and the truck was filled with smoke. Bystanders said truck had flames inside going up windshield but had died down. They had a fire extinguisher but the truck was locked and they didn't want to open the truck since the flames were dying down until the fire department arrived. Fire department arrived and I unlocked truck door and opened up truck to let smoke out. Small fire rekindled under dash on passenger side, put out immediately with dry chemical fire extinguisher. Opened hood to disconnect battery cables for fire department and did not notice any damage in engine compartment. Interior dash was completed burned away in a 4-5" wide area between radio/hvac control console and glove compartment door. Area that includes the auxiliary power plug and a dash vent. I made no changes/modifications or add ons to the truck after purchasing the vehicle, and had nothing plugged into the auxiliary power plug at any time. Dash is completely gone in this area plus a small portion above the passenger airbag area of dash. Vent is completely gone, auxiliary power plug is completely burned away with just a metal frame of the plug remaining laying on the floor of the truck on top of some melted, piled-up plastic from dash. No wiring was attached to the metal frame anymore. Fire department made a report, so police were not called to the scene. Ford consumer department was notified but declines liability.

Vehicle was parked in driveway with doors locked and ignition in the off position. No one was near or in the vehicle. Looked out window and noticed what looked like mist from a water sprinkler from the front side of truck. Looking closer, I realized it was smoke and then saw flames from the tire well and under the hood by the windshield wipers. Called 911. The fire department arrived very quickly, putting the fire out. Their assessment was it was an electrical short which had caused the fire. The fire caused the hood hydraulic lift to explode like a rocket, hitting the windshield, cracking it and then shooting off into the yard. The frames inside the engine housing by the drivers tire burnt the housing completely away. The wiring has been completely burned and melted away inside the engine compartment. All the plastic fluid containers melted, the entire engine housing, engine and all electrical components under the hood were burned up or damaged in some way by this fire. The truck will not start or run. None of the lights work, radio, heat, air or power functions work. The truck is totally inoperable. I contacted the insurance company and they directed me to this site to look for fire related defects and to file a complaint. The truck has not been repaired as it is beyond repair since all the wiring and most of the insides under the hood have burned up or melted.

Our truck caught on fire in the engine compartment at 4:00 in the morning. There was no after market wiring done on the truck. We bought the truck new, and have never had any trouble with it. This was not an insurance job. We took our full coverage off of it when we bought our car. The truck is available for an investigation.
