Check Engine Light Flashing

A flashing check engine light is a serious indicator on any vehicle, and on a 2025 Jeep Gladiator it typically signals an active misfire that can damage the catalytic converter and reduce drivability. Flashing warns you to stop driving if safe and have the vehicle inspected immediately. At Larry H. Miller Chrysler Jeep Dodge Ram Boise we treat flashing lights as high priority: our certified technicians perform an expedited inspection, test battery and ignition systems, and isolate misfire causes—whether ignition coils, spark plugs, fuel delivery, or electrical faults. We also check battery health and charging, since voltage irregularities can mimic or exacerbate faults. We recommend addressing flashing alerts promptly to avoid more costly repairs and to maintain emissions compliance. Review current promotions and service specials before you come in, and remember we offer service financing to help manage unexpected costs.
