On the 2019-2025 Chevrolet Blazer, the AGM battery required for the auto start-stop system degrades prematurely, often failing within 2-3 years. When the battery weakens, the start-stop system disables itself and various electrical warnings appear. The auxiliary battery (on equipped models) can also fail, compounding the issues.

This issue also affects: Buick LaCrosse, Buick Regal, Chevrolet Cruze

Common Symptoms

  • Start-stop system not functioning
  • Battery warning messages
  • Multiple warning lights on startup
  • Slow cranking
  • Electrical accessories resetting

How to Fix

Replace the AGM battery with a genuine ACDelco AGM battery — standard flooded batteries are not compatible with the start-stop system. After replacement, a battery sensor reset via a scan tool is required. Some owners permanently disable start-stop with aftermarket modules if they find the feature annoying.

Typical repair cost:$200 - $400
