2026 Ford F-350 Sd Owner Complaints

When we plug our F350 into our fifth wheel trailer, the lights work until we put the brakes on once we apply the brakes the rear right brake light and turn signal no longer work. So we are forced to drive with only one working brake light and tail light when we disconnect and reconnect. It does the exact same thing again we have had two other pick ups both GM products connected to our trailer and it works perfectly. We’ve had a mechanic look at it and tell us it was not our trailer. It is our truck. I’ve contacted Ford who refuses to do anything about it. We get brake module error messages from the truck as well as brake lighting, module errors from the truck.

I purchased my 2026 Ford F-350 Platinum from Sandy Sansing Ford Lincoln on June 11, 2026. I was not informed that the vehicle has two unrepaired/unresolved Recall's. Both of the recalls were issued in March, 2026. The Dealership had this vehicle on their lot from September, 2025 to the date that I purchased it. The first recall is 26E01 "Powertrain Control Module PCM Software" and the second recall is 26C10 "Trailer Module Reprogramming." I was not aware of and it was never brought to my attention at the time of sale that the vehicle had two recalls and, I purchased the vehicle three months after both of these recalls were issued.

Recall service not available right now. We have a remedy but parts are not available right now. We will inform you when the service is available. Or, you can contact your dealer.Description On your vehicle it is possible that the trailer module trm may lose communication at vehicle start-up. If a trm loss of communication occurs and a trailer is connected to the vehicle, trailer stop lamps and turn signal indicators will not function. Additionally, for trailers equipped with electronic trailer brakes, the trailer brakes will not function. This loss of communication can occur with-or-without a trailer connected to the vehicle and can only initiate at vehicle start-up. If this occurs, a trailer brake module fault notification will pop-up on the vehicles instrument panel cluster. The vehicle brake and turn signal lamps will continue to operate normally and are not affected by this trm fault. If you do not tow with your vehicle, you may wait for ota deployment for your vehicle remedy. Safety Risk This may result in inoperable trailer brake lights, trailer turn signals and trailer braking functions that can reduce a drivers ability to control an attached trailer and make the trailer less visible to other drivers, increasing the risk of a crash. Remedy Software is available to repair your vehicle. Ford Motor Company has authorized your dealer to reprogram your vehicles trm free of charge. Next Steps Contact your dealer for more information to schedule the free service.
