The hybrid's engine disconnect clutch worn to where it can no longer carry the torque of an engine join without excess slip. Every blend between electric and engine drive slips this clutch on purpose, and hard acceleration at the exact moment of join is its hardest duty — so a hard-driven hybrid wears it faster than the odometer suggests.

The wear announces itself at the seams: shudder as the engine joins, slip codes during blends, then heat codes as the slipping lengthens. Caught at the shudder stage it is a clutch; ignored to the heat stage, the debris and glazing spread the bill.
