Problem Mack Trucks, Inc. (Mack) is recalling certain 2024 Granite and TerraPro vehicles. The rear lifting bracket that attaches to the engine cylinder head may be insufficiently secured, which can allow it to detach. Risk A rear lifting bracket that detaches while the engine is being lifted can result in the engine falling or swinging, increasing the risk of injury. Fix Dealers will inspect and replace the flanged stud in the rear lifting bracket, as necessary, free of charge. Owner notification letters were mailed December 9, 2023. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0452.

Two numbers, one recall

Every safety recall carries two identifiers. SC0452 is the number Mack assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 23V731000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.
