The short answer

NHTSA received Mack Trucks, Inc.’s report on Dec 22, 2023. Copied from NHTSA on Oct 19, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

An improperly installed wheel end hub assembly can leak oil, causing the axle spindles to loosen or fracture and increasing the risk of a crash.

Mack Trucks, Inc (Mack) is recalling certain 2024 Granite vehicles.

The bearing journals may not be fully seated in the steering knuckle assembly, preventing the proper installation of the wheel end hub assembly.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
