Check Engine Light Flashing

A flashing check engine light on a 2020 Dodge Journey is a serious warning that typically indicates a misfire or a condition that could damage the catalytic converter. A flashing lamp means the engine is misfiring under load, introducing unburned fuel into the exhaust stream and creating heat that can rapidly harm emission control components. Immediate inspection at Larry H. Miller Chrysler Dodge Ram FIAT Denver can prevent further damage: our technicians perform a rapid scan, cylinder balance checks, and ignition and fuel delivery tests to isolate misfires or electrical causes like a failing battery or alternator. We emphasize OEM repairs and offer transparent pricing, so customers understand both immediate costs and long-term savings from fixing issues correctly the first time. Ask about our service financing to address urgent repairs now and repay over time. Check our service specials for seasonal discounts, then schedule service online or call us for expedited appointment options.
