Check Engine Light Flashing

A flashing check engine light in a 2026 Ford Mustang Mach-E usually indicates a severe or active fault that can affect drivability or the EV battery system.

Ignoring a flashing light risks reduced performance, safety cutbacks, or further damage that increases repair costs. At David McDavid Ford, our technicians prioritize immediate assessment: we run a full diagnostic, check high-voltage interlocks, evaluate thermal management, and determine if the vehicle should be limited or towed for safe service.
