Check Engine Light Flashing

The check engine light flashing in a 2024 Chevrolet Suburban is a clear alert that the engine is misfiring or that conditions exist which could quickly damage the catalytic converter or other critical systems. When the light flashes, stop driving if safe and have the vehicle inspected immediately. At Herb Chambers Chevrolet in Massachusetts, our technicians use dealer-grade scan tools and OEM procedures to identify misfire causes — from ignition coils and spark plugs to fuel delivery and sensor faults. Addressing a flashing light promptly prevents escalation into costly repairs, preserves fuel economy, and maintains emissions compliance. We also provide battery services and replacements for the Suburban, since weak batteries or charging issues can exacerbate engine performance problems; replacing a battery with a certified OEM-equivalent unit protects vehicle electronics and ensures a reliable start.
