Check Engine Light Flashing

A flashing check engine light in a 2018 Honda Clarity signals an active misfire or a condition that could damage the catalytic converter or hybrid components. For plug-in hybrids like the Clarity, a flashing light can also indicate an intermittent charging or high-voltage system fault; those must be assessed by technicians trained in hybrid systems. At Coggin Honda Fort Pierce, our service bays are equipped for safe high-voltage diagnostics and battery checks, and our factory-trained technicians follow Honda procedures to protect you and the vehicle. We often identify the root cause faster than general shops, which reduces immediate disruption and long-term costs from avoidable damage. If a battery replacement is necessary, we use OEM or Honda-approved components to maintain performance and warranty coverage. Ask about our current service specials, and remember that service financing is available so you can address urgent repairs now and pay over time. Don’t wait: a flashing light can escalate rapidly—please schedule appointment online or contact our Fort Pierce service team for immediate guidance.

Resetting the check engine light on a 2018 Honda Clarity without diagnosing the underlying issue can hide symptoms and allow small problems to become costly failures.

This transparent approach protects long-term value, ensures technical accuracy, and maintains warranty integrity.
