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.

Service Bulletin/Repair Instructions
According to Ford Recall 25V793: "According to Ford’s records, the remedy software for Safety Recall 20S73 may not have been installed correctly during a prior dealership visit. Because the correct software may not have been installed on your vehicle, the underlying condition specified in Safety Recall 20S73 may still exist. On your vehicle, it may be possible that the engine cover insulation does not fully extend to the perimeter of the factory engine cover. This may result in elevated temperatures at certain areas of the engine cover surface in the passenger compartment on both driver and passenger sides. Direct and continuous contact with exposed skin at these locations may increase the risk of skin irritation and/or a minor burn.
