Ford is recalling all 2015-2017 full size Transit vehicles except 156” and 178” wheelbase Chassis Cab and Cut-Away bodies. This will affect the Winnebago Paseo and the Coachmen Crossfit.
From the NHTSA bulletin: "The flexible coupling between the transmission and driveshaft in certain 2015-2017 Transit vehicles may prematurely deteriorate and crack with increasing mileage. A cracked flexible coupling will result in an overt moaning noise from underneath the vehicle, along with tactile vibration. Continued driving with a cracked flex coupling may cause separation of the driveshaft, resulting in a loss of motive power while driving, or unintended vehicle movement in park without the parking brake applied. In addition, separation of the driveshaft from the transmission can result in secondary damage to surrounding components, including brake and fuel lines. Ford is not aware of any reports of accident or injury related to this condition."
I don't know what Ford considers an "accident" but two members of the FordTransitUSA forum reported failures while driving. One of them had two fleet vehicles with over 140K miles on them before failure, the other had failure at 42K miles. Damage to the underside of the vehicles was extensive.
Dealers will not be allowed to sell any Transit vans until the recall corrections have been installed. Earliest reported parts distribution is mid-July.
For current owners, Ford will replace the part every 25K miles with the same part
until a permanent fix can be effected.
