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.
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.
