What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect (steering knuckle/axle spindle) that can lead to fracture and increased crash risk, meeting the criteria for a Severe rating.

Plain-English summary

Mack Trucks, Inc. is recalling certain 2024 Mack Granite vehicles. The recall addresses a defect where bearing journals may not be fully seated in the steering knuckle assembly. This issue prevents the proper installation of the wheel end hub assembly.

An improperly installed wheel end hub assembly can leak oil, causing the axle spindles to loosen or fracture. This condition increases the risk of a crash. No specific number of affected vehicles is provided in the source text.
