Recall 20V319 covers 12,200 2019-2020 International Motors Chevy 4500HD, 5500HD, and 6500HD trucks for ABS warning-light software. Free repair at franchised dealers.

International Motors is recalling 12,200 2019-2020 Chevy 4500HD, Chevy 5500HD, and Chevy 6500HD medium-duty trucks because the ABS warning light can stay dark when the ABS system malfunctions. That leaves the driver without a key brake-system alert and increases crash risk; International Motors dealers will update the EBCM software free of charge.

What's wrong?

The body control module software calibration is the truck's control logic for body and warning-lamp functions. On affected 2019-2020 International Motors Chevy 5500HD, Chevy 4500HD, and Chevy 6500HD trucks, it works with the electronic brake control module, which manages anti-lock brake system functions and sends fault information to the dash.

The defect is an error in the body control module software. If the body control module loses communication with the electronic brake control module, the ABS malfunction indicator light does not illuminate as required. The issue is with the warning-light command, not a broken brake line or a worn brake part.

What an owner sees is different from the missing ABS light. If this communication loss happens, the service-engine-soon malfunction indicator light illuminates instead. That light is the warning sign to take seriously and report when scheduling service.

Who's affected?

Spans the Chevy 4500HD, Chevy 5500HD, and Chevy 6500HD across the 2019 and 2020 model years, all tied to the same BCM software calibration.

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?

An ABS malfunction that the driver does not recognize increases crash risk. The service-engine-soon light turns on if the BCM loses communication with the EBCM, so treat that warning as a reason to schedule service promptly and drive cautiously until checked. Repair is free at any franchised International Motors dealer.

What should I do?

  1. Check your VIN to confirm your 2019-2020 International Motors Chevy 5500HD, Chevy 4500HD, or Chevy 6500HD truck is included in this recall.
  2. Contact a franchised International Motors dealer to schedule the free BCM software update that fixes the ABS warning-light issue.
  3. Bring the recall notice if you have it. If not, reference recall number 20V319 when you call.
  4. Drive cautiously until the software update is complete, and treat any brake or ABS warning light as a reason to contact the dealer before driving again.

What happens at the repair

At the dealer, an International Motors technician updates the software calibration for the body control module (BCM) so the brake system warning logic uses the corrected programming. The software update and labor are free under recall 20V319. If you already paid out of pocket for a related BCM software repair before the recall notice, the manufacturer's standard reimbursement plan covers documented expenses. Bring repair paperwork and proof of payment to the service desk.
