What's wrong?
The air bag sensing and diagnostic module, or SDM, is the control unit that monitors crash sensors and manages the air bag system on 2024-2025 Chevrolet Silverado 4500, Silverado 5500, and Silverado 6500 trucks. When it is set up correctly, it checks the restraint system at start-up and keeps the air bag controls ready to operate as designed.
On the affected trucks, the SDM was installed but not activated during assembly. GM traced the problem to module-programming tools used at the plant that were not configured correctly for end-of-line setup. In plain terms, the truck left the factory with the air bag control module in the wrong mode, so the module does not perform as designed.
If this condition is present, the airbag telltale flashes continuously after the vehicle starts. That flashing airbag light is the warning sign to report to the Chevrolet dealer.
Who's affected?
Covers the Silverado 4500, 5500, and 6500 medium-duty truck classes across the 2024 and 2025 model years, all tied to air bag system software.

What's the safety risk?
If the air bags are inactive, they will not deploy in a crash, increasing injury risk. If the airbag telltale flashes continuously after startup, treat that as a warning sign and schedule the recall repair soon. Repair is free at any franchised Chevrolet dealer.

- Check your VIN to confirm your 2024-2025 Chevrolet Silverado 4500, Silverado 5500, or Silverado 6500 is included in this recall.
- Contact a franchised Chevrolet dealer to schedule the free SDM activation so the air bags can deploy in a crash.

What happens at the repair
At the dealer, a Chevrolet technician activates the air bag sensing and diagnostic module covered by recall 24V738. The module is the part that helps the vehicle detect a crash and command the air bags when deployment is needed. Parts and labor are covered, and the recall repair is free. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because all covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
