Is there an exact hybrid-system warning or diagnostic code?
The exact message/code is stronger evidence than guessing which hybrid component failed.

Start with what the car is doing.
Choose a symptom and, when possible, an exact vehicle code. Work through structured observations first, then compare them with reviewed owner evidence. CarFactBook does not invent a diagnosis or rank a failed part from unsupported anecdotes.

Safety first. High-voltage hybrid/EV systems can be hazardous. Do not open or probe high-voltage components unless you are trained and equipped for the vehicle.
Does the vehicle enter READY normally?
READY status is a useful observation for the next diagnostic step.
These checks organize observations and safety decisions. They are not a substitute for manufacturer service procedures or a qualified diagnosis, and CarFactBook does not assign a failed part without supporting evidence.
