Recall Insight
The number of affected units is not disclosed in the agency filing, which is common for drug and food recalls where lot-level tracking supersedes unit counts. Distribution scope (see Distribution below) directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory. Consumers holding this product should act on the agency's documented remedy above rather than relying on general guidance.
Within the same product category the archive holds 6 closely related recalls, 3 from NHTSA - clustering in a narrow category often points to a systemic quality-control or supplier issue rather than a one-off defect. Always verify the recall number against the official agency record before acting.

Reason for recall
Daimler Trucks North America, LLC (DTNA) is recalling 2021 Western Star 4700 and 5700, Freightliner Business Class M2, Cascadia, and Custom Chassis XC Chassis vehicles manufactured with a certain steering arm configuration with air disc brakes identified by the axle assembly supplier. On certain vehicles, one of the six brake caliper mounting bolts on the driver side steer axle may have been incorrectly tightened.
Hazard
The loose bolt could result in the other caliper bolts to loosen. Insufficiently tightened bolts may not provide adequate clamping force between the brake caliper and brake anchor plate, resulting in reduced brake effectiveness, increasing the risk of a crash.
Remedy, what to do
DTNA will notify owners, and dealers will inspect and repair as necessary, free of charge. The recall began March 17, 2021. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-873.
