Western Star is recalling 53 2020-2021 vehicles, including 4700, 4900, 108SD, 114SD, and Coronado models, because the certification label lists a gross axle weight rating that exceeds the tire capacity rating. That mismatch can lead owners or operators to overload the axles, increasing crash risk; Western Star dealers will correct the label free of charge.

What's wrong?
The certification label on these 2020-2021 trucks tells an owner, driver, inspector, and service shop the official weight ratings for the vehicle. One key number is the Gross Axle Weight Rating (GAWR), which is the maximum weight that an axle is rated to carry. That rating has to match the capacity of the tires fitted to that axle.
On affected 4700, 4900, 108SD, 114SD, and Coronado trucks, the label lists a GAWR that is higher than the tire capacity rating. The printed label gives a number the tires are not rated to support. DTNA found the issue after dealer feedback showed a second incorrect label was left in place during work tied to an earlier recall.
There is no warning sign before failure. The issue is found by checking the certification label and confirming whether the GAWR printed there exceeds the tire capacity rating for the truck.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Incorrect axle weight ratings on the certification labels can lead owners or operators to load the vehicle beyond its axle limits. Overloaded axles reduce the safety margin and increase crash risk. Until the label is corrected, avoid loading near the posted limits and schedule the dealer repair. Repair is free at any franchised Western Star dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 Western Star 4700, 4900, 108SD, 114SD, or Coronado is included in this recall.
- Contact your nearest franchised Western Star dealer to schedule the free GAWR certification-label correction so the axle rating label matches the tire capacity.
- Bring the recall notice if Western Star has mailed one. If not, reference recall number 20V634 when you call.
- Avoid loading the truck beyond the tire capacity shown on the tire sidewall until the corrected label is installed.
- Call Western Star customer service at 1-800-547-0712 with questions about the free label repair.
What happens at the repair
At the dealer, a Western Star technician installs corrected certification labels that show an accurate Gross Axle Weight Rating for the vehicle. The incorrect label overstates the tire capacity listed for the axle. The recall repair is free, and parts and labor are covered. The dealer updates the label rather than replacing a mechanical part, so ask the service desk to confirm the corrected GAWR label has been installed before you leave.
