Check Engine Light Flashing

The check engine light flashing in a 2024 Jeep Grand Cherokee usually indicates a severe misfire or condition that could damage the catalytic converter. A flashing light is an urgent warning — you should stop driving if you notice poor power, heavy vibration, or strange noises. At Larry H. Miller Chrysler Jeep Dodge Ram Boise our technicians use factory diagnostic equipment to quickly capture freeze-frame data, identify misfire cylinders, and test ignition and fuel components. Prompt diagnosis prevents secondary damage; for example, an unresolved misfire can overheat and ruin the catalytic converter, turning a simple ignition repair into a large emissions replacement. We emphasize transparent pricing, and our service advisors will explain immediate and long-term cost implications so you can make a confident decision. Check our current service specials and schedule service online to get fast attention. If you prefer to speak with a technician, call us and we’ll help triage symptoms and prioritize safe towing or repair options.
