2023-2024 Chevrolet Trucks/SUVs Recall 24V674: Brake Warning

Recall 24V674 covers 449,671 2023-2024 Chevrolet, GMC, and Cadillac trucks and SUVs for missing low-brake-fluid warnings. Free software update by OTA or dealer.

What's wrong?

The electronic brake control module is the computer that helps manage brake system warnings and power-assist control on affected 2023-2024 trucks and SUVs. Part of its job is to watch the brake fluid level and turn on the red brake warning telltale when fluid loss reaches the required threshold. That light tells the driver the brake system needs attention.

In this recall, the problem is not a broken brake line or a leaking reservoir. GM found a mismatch between the module software and the calibration file installed at the assembly plant. Because those two pieces do not match, the system fails to detect and display the required low-fluid warning during a brake fluid leak.

The owner warning sign listed for this recall is a red brake telltale before total loss of brake fluid occurs. Treat that red brake warning light as a stop-and-check signal, because the brake system is reporting a fluid-loss condition.

Who's affected?

Covers Chevrolet, GMC, and Cadillac SUVs and pickups from the 2023-2024 model years, all tied to the same electronic brake control module data file.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.

What's the safety risk?

Low brake fluid can reduce braking performance and increase crash risk, especially if the warning light does not alert you early enough. A red brake telltale appears before total brake fluid loss, so treat that light as a reason to stop safely and contact a Chevrolet dealer. Repair is free at any franchised Chevrolet dealer.

What should I do?

1. Check your VIN to confirm your 2023-2024 Tahoe, Suburban 1500, Yukon Xl, Escalade Esv, Silverado 1500, Escalade, Sierra 1500, or Yukon is included in this recall.
2. Contact a franchised Chevrolet dealer to schedule the free eBCM software update that fixes the missing low-brake-fluid warning light, or ask whether the over-the-air update is available for your vehicle.
3. Reference recall number 24V674 and GM recall N242447990 when you call the dealer.
4. Bring the owner notice if you have it, and ask the dealer to confirm that the software update was completed.
5. Drive cautiously until the update is complete. Leave extra following distance and respond at once to any brake warning light or change in brake pedal feel.

What happens at the repair

The eBCM software update can be installed over the air or completed at the dealer. If the vehicle needs dealer service, a Chevrolet technician updates the electronic brake control module software so the brake warning light works as required when brake fluid is lost. Parts, labor, and the software update are free under the recall. If you've already paid out of pocket for a related eBCM software repair before the recall notice, GM's general reimbursement plan on file covers documented expenses. Bring repair paperwork and receipts to the service desk or contact the listed GM brand customer service line.
