Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

According to FORD Recall 26C10/26V104: "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 vehicle’s instrument panel cluster."

According to Ford Recall 26V090: "Certain vehicles may have been built without the cotter pin that secures the brake booster pushrod to the brake pedal, which can cause the brake booster pushrod to separate from the brake pedal. The brake booster pushrod may disconnect from the brake pedal. This can result in a loss of braking function while driving, increasing the risk of a crash. Ford has issued a “do not drive vehicle” order. The vehicles in this program are not to be driven until the vehicle passes the inspection or the repair has been performed."
