Known issues for this generation

Safety recall 19S38 (NHTSA 19V-767) covers certain 2015-2017 Transit vans whose flexible coupling between the transmission and driveshaft may prematurely fail. If the coupling fails the van cannot move under its own power, the disconnected driveshaft can strike and damage the brake and fuel lines, and the van can roll away if it is left in Park without the parking brake applied. As an interim repair Ford's dealers replace the flexible coupling every 40,000 miles; the final remedy fits a driveshaft front section with a mechanical universal joint in place of the coupling, free of charge. This recall supersedes 17S15 (NHTSA 17V-408) and carries over the vans covered there, except those that had already received a mechanical u-joint and any 156-inch or 178-inch wheelbase chassis cab and cutaway bodies.
