FCA Recalls 2016 Ram HD Trucks for Defective Main Output Shaft
Issue Could Cause Vehicle Rollaway
Fiat Chrysler Automobiles (FCA) is issuing a recall affecting 930 2016-model-year Ram 3500, 4500, and 5500 four-wheel-drive trucks. A misshapen main output shaft was discovered, which could create voids and a possible shaft fracture. If a shaft fracture were to occur, it could result in the loss of motive power, the inability to place the vehicle in park, and increasing the chances of a vehicle rollaway.
The component in question was manufactured by supplier Borg Warner. FCA had received one complaint on a vehicle that reportedly would not move except in four-wheel drive. Ultrasonic inspection of the main output shaft and other shafts in inventory found others with chevron-shaped voids. Borg Warner was able to recreate the issue and attributed it to an interruption of the forging cycle allowing the parts to cool, resulting in the void.
FCA and NHTSA are unaware of any injuries or accidents related to this issue. As of July 26, most affected vehicles were unsold, with an estimated 243 vehicles delivered to customers between April 1, 2016, and June 6, 2016, that are potentially affected. Owners of the affected vehicles will be notified by mail, with the recall campaign starting August 10. Owners can call 1-800-853-1403 and reference recall campaign S48 or visit recalls.mopar.com and enter their vehicle’s 17-digit VIN number to see if their truck is subject to the recall campaign.
