United States: NHTSA, as of 2026-10-19
21V2930002021-04-26. STEERING. Mack Trucks, Inc. (Mack) is recalling certain 2019-2020 LR vehicles. The steering transfer case may have an insufficient amount of oil.
Canada: Transport Canada, as of 2026-10-19
20212482021-04-26. Steering. Issue: On a small number of trucks, the steering transfer case was not properly filled with oil. As a result, the bearings may fail and the steering could lock-up. Safety Risk: A loss of steering control could create the risk of a crash. Corrective Actions: Mack will notify owners by mail and instruct you to take your truck to a dealer to inspect, and if necessary, replace the steering transfer case. To reduce the safety risk, Mack recommends that you should avoid driving your truck until this recall is completed.

A campaign lists a year, a make and a model, and often only some of the vehicles built. A list with nothing on it is not a clearance either. The lookups below check one VIN.
