The engine and cluster showed and made noises indicating that the hybrid system was malfunctioning. The cluster indicated a speed limit at high speeds, but never did so. The electric drivetrain was disconnected and the handling and power were severely affected. It was dangerous because the distracting and concerning issues were during a rapid speed and in dangerous conditions with no clear remedy. The check engine, red turtle, and battery lights indicated the problem, but not beforehand. There were some warranty fixes around the battery including recall work.
