Check Engine Light Flashing

The check engine light flashing on a 2018 Chevrolet Express Cargo 2500 is a sign of a severe misfire or an issue that could damage the catalytic converter if you keep driving. A flashing indicator often means unburned fuel is entering the exhaust, which raises temperatures and risks costly downstream repairs. At Herb Chambers Chevrolet in Massachusetts our priority is to protect your van’s towing capability, cargo reliability, and uptime. We advise stopping safely and bringing the vehicle in immediately for a controlled diagnostic and inspection. Our factory-trained technicians use OEM-level scanners, smoke testing, and live-data analysis to pinpoint misfires, ignition faults, or fuel delivery issues. Addressing a flashing check engine light promptly saves money over time by avoiding catastrophic exhaust or engine harm, preserves fuel economy, and keeps your cargo operations on schedule. Take advantage of our service financing if you prefer to repair now and pay later. To act quickly, schedule service and review current service specials before you arrive.
