The vehicle’s electronic control modules (ECMs) were prone to software bugs in the initial years, causing unpredictable behavior such as false error codes, improper hybrid system activation, and inconsistent regenerative braking responses. These glitches required third-party diagnostic tools and firmware updates to resolve, highlighting early limitations in Toyota’s hybrid software architecture.
