What is wrong

Mack Trucks, Inc. (Mack) is recalling certain 2026 Anthem (AN), 2026-2027 Pioneer PR (4), Pinnacle (PI/PN), Granite (GR), and 2027 Anthem AN (4) vehicles. The wheel lug nuts may loosen and allow the wheel to detach.

The risk

Wheel detachment can cause a loss of vehicle control or create a road hazard, increasing the risk of a crash or injury.

Why wheel defects matter: Loose or failing wheel fasteners can let a wheel separate from the vehicle while driving.

The remedy

Owners are advised not to drive their vehicles until the repair has been performed. Dealers will inspect the wheel and hub mating surfaces, remove any masking material, and replace any worn components if necessary, free of charge. Owner notification letters were mailed June 22, 2026. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0495. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on May 31, 2026.

What to do

  1. The manufacturer has told owners not to drive these vehicles until the remedy is done. Ask the dealer about towing rather than driving in.
  2. Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
  3. Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-351 and the manufacturer’s number SC0495.
  4. If you hear grinding or feel vibration from a wheel, stop driving and have it inspected.
  5. Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.

Check by VIN

A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.

Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.

Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
