It might have happened already, and/or will happen within the next year, The car's High
voltage batter counter age will approach the 9 year mark. The system which controls the
Hybrid powertrain to have the car run properly in EV mode, will become non-existent.
Forcing the gasoline engine to come on more frequently, which basically becomes more
like a regular car.
This issue can be fixed, by resetting the battery age counter with an IDS tool from the
dealership, or you cen perform the fix yourself. The problem is, not many dealers know
about this issue or refuses to do the fix.
Since you are buying the car from them, tell them to reset the battery age to 1 year or 0
year. So the car functions on EV mode as the vehicle is designed for many more years,
