What's wrong?
The hub cap kit on the 2021-2022 Mack Anthem (An), Granite (Gr), Granite (Gu), Pinnacle (Chu), Pinnacle (Cxu), and Pinnacle (Pi/Pn) trucks is a decorative wheel hub cover. It sits over the wheel hub area and is held in place so it stays attached while the truck is moving.
On these trucks, the compression spring in the hubcap does not provide enough pull-off force for this application. That means the cover is not retained as firmly as Mack intended. With normal vehicle movement, vibration, and wheel rotation, the hubcap can separate from the wheel instead of staying secured.
Mack traced the fix to a redesigned hub cover with proper retention force. There is no warning sign before failure. An owner is not given a dashboard light, sound, or handling change that reliably signals the cover is about to come off.
Who's affected?
Spans the Anthem, Granite, and Pinnacle lines across the 2021 and 2022 model years, all tied to decorative wheel hub covers.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A separated hubcap can fall into traffic and create a road hazard, increasing the risk of a crash. If your VIN is included, schedule service soon and avoid trips that are not necessary until the dealer removes the hubcap. Repair will be free at any franchised Mack dealer once available.
What should I do?
- Check your VIN to confirm your 2021-2022 Mack Anthem (An), Granite (Gr), Pinnacle (Chu), Pinnacle (Cxu), Granite (Gu), or Pinnacle (Pi/Pn) is included in this recall.
- Review Mack's owner letter, mailed June 30, 2021, or call Mack customer service at 1-800-866-1177 if you never received it.
- Ask a franchised Mack dealer whether the free hubcap-removal repair is open for recall number 21V416.
- Keep the truck out of service if a hubcap is loose or missing, because a separated hubcap can create a road hazard.
- Bring the recall notice to the dealer if you have it.
What happens at the repair
At the dealer, a Mack technician will remove the hubcap covered by recall 21V416. Because the remedy status is listed as under development, do not treat the final dealer visit as open until Mack or the dealer confirms availability. Once available, the hubcap removal is free under the recall, with parts and labor covered. Mack has a general reimbursement plan on file, so ask Mack customer service or the dealer service desk how to submit documentation for a related hubcap repair you already paid for.
