Check Engine Light Flashing

The moment a check engine light starts flashing on a 2022 Chevrolet Suburban, consider it urgent: a flashing light typically indicates active misfire, which can allow unburned fuel into the exhaust stream and overheat the catalytic converter. Left unchecked, this condition risks severe engine damage and expensive downstream repairs. At Herb Chambers Chevrolet in MA our first priority is safety and fast containment. Certified technicians perform a targeted diagnosis using GM factory tools to identify ignition or fuel delivery faults, then recommend the precise repair using OEM parts to restore reliability. We explain repair options clearly, provide transparent estimates, and outline warranty coverage — note that warranty-covered repairs must be completed at a certified dealership. To reduce immediate and long-term costs we offer service financing, helping you get essential repairs done without delay.
