Check Engine Light Flashing

A flashing check engine light in a 2024 Jeep Gladiator usually signals a serious misfire or critical condition that can damage the catalytic converter or cause drivability failure. When the light flashes, stop driving as soon as it’s safe and bring the vehicle to Larry H. Miller Chrysler Jeep Tucson in Tucson, AZ, for immediate attention. Our technicians are factory-trained and equipped with OEM-level diagnostic tools to isolate ignition, fuel, and sensor faults quickly. Addressing a flashing light early prevents expensive downstream repairs; for example, a misfire left unchecked can ruin a catalytic converter (repair costs can climb into the thousands) while a prompt, precise repair typically resolves the issue at a fraction of that cost. We back repairs with transparent estimates, OEM parts, and the reassurance that warranty-covered items remain protected when serviced at a certified dealer. Ask about our current service specials, and if financing would help, take advantage of our service financing options to get repairs done now and pay over time. To prevent further damage and restore safe operation, schedule service online or call our service team to arrange immediate diagnostics and repair.

At Larry H. Miller Chrysler Jeep Tucson we explain costs and consequences in plain terms and recommend the most economical repair path that preserves vehicle value and longevity.
