Check Engine Light Flashing

The check engine light flashing on a 2019 Jeep Cherokee is a warning that should not be ignored — it typically indicates an active misfire that can allow unburned fuel into the exhaust stream and quickly overheat the catalytic converter. Continued driving with a flashing light risks severe engine and emissions system damage, which can lead to significantly higher repair invoices than addressing the cause early. At Larry H. Miller Chrysler Jeep Dodge Ram Boise we recommend you safely pull over, limit engine load, and contact our service center for guidance. If necessary, we can arrange towing to our facility to prevent further damage. Our technicians have factory training and access to OEM parts and diagnostic tools to isolate misfires, whether they stem from ignition, fuel delivery, or engine mechanical issues. We promote transparency: you’ll receive a clear diagnosis, cost estimate, and repair timeline.
