2011 Ford F-150 electrical problems

Filed Sep 25, 2026 · Electrical · GA · fire

I was parking the vehicle and turned off the engine when the speakers gave out a loud noise. I turned the truck on to see if it would continue but there was no music and smoke began coming out around the radio. I moved the truck away from building and retrieved the fire extinguisher from the back seat. I noticed the "door ajar" warning was on even when the doors were closed. The smoke subsided and I did some quick research online. I was able to find a lot of information about the wire harness between the driver's side rear door and door frame being damaged, producing these symptoms. I disconnected the battery and removed the sheath from the wiring harness. Three wires were severed and several were frayed. (see attached photos) I contacted the local Ford dealership and they explained how it could be replaced at the wire connector in the door frame. Most trucks have a connector in the door frame, this truck does not so the Ford tech offered to solder the wires together. I am experienced in wiring and auto mechanics so I completed the repairs myself as he described.

I bought this truck used about one year ago. Since then I have not had much time to use it. In the last three months I have had some time to drive it. Three times in those months this issue has occurred. Luckily they all occurred on my property and no damage happened except to the truck. First time it happened an exterior mirror was knocked off, a running board was bent, scratches and dings to the to the paint, and a tailight was damaged. This all happened in reverse due to a gate opening I was going through. The motor all of a sudden had a massive spike in RPMs and a violent lunge and slide of the vehicle. I learned later that it was due to a flawed part in the transmission called a molded lead frame. Transmission is Fords 6R80 6-speed automatic. Last time it happened was on 09/16/2026. It has not been inspected by any entity because apparenty I live too far in the "boonies" for anyone to come this far but the vehicle is available for inspection upon request.

I am having a lead frame issue. At various speeds, the vehicle will just down shift, locking the tires and causing a hazard for other drivers which could be a very dangerous situation. I was impacted from the rear due to this occurrence. It causes extreme jerkiness when doing this which is also injurious to my back and neck and shoulders.

What component or system failed or malfunctioned, and is it available for inspection upon request? “We lost power while driving, along with a weird downshift today, 5/16/2026. This is happen one other time, however not as bad.” How was your safety or the safety of others put at risk? “It could have been way worse, lucky there was a left turn lane that avoided us being rear ended by the vehicle behind us.” Has the problem been reproduced or confirmed by a dealer or independent service center? “Not for this time, but it will be going in first thing Monday. We did have it looked at back in April when it did a weird downshift while driving, but they couldn’t find an issue then.” Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? “No, but it will be after this incident.” Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? “No warning lights, just loss of power and an intense downshift. The first time the downshift thing happened was back in April, but nothing more. We had a mechanic look at it, but nothing happened for him then.”

My vehicle has abrupt unintended downshifts straight down to first gear at fast speeds, which is causing rear-wheel lockage near heart attack and near-loss of control spinout. The sudden downshifting causes a loud violent high extreme RPM engine over rev. sounding as if it is about to blow up or an internal explosion. This is occurring at highway speeds up to 70 mph. At these speeds, is an immediate risk to me and others! Causing a fatal high-speed rollover or a multi-vehicle collision due to this malfunction! This was a recall 19S07 for my year of truck but my Vin was somehow was not on the list which I guess makes me not qualified unless I get into a crash and then have a lawsuit.

The first indication of problems came when I tried to put the truck in gear and I noticed that the reverse light didn't come on and it wouldn't engage into the gear then as I was traveling down a three-lane highway in the middle lane the car started jerking and like it didn't want to go and then I got to a red light and the truck would not move so I was stuck in the central lane but after engaging the gear several times I managed to get the vehicle into a gas station parking lot where I call the dealership after finding out that I had the trouble code that was referred in the recall and the vehicle was towed to Duval I mean it was told to Hogan forward on Atlantic boulevard .where it's now under inspection.
