Unhappy Motor won't shut off

OMG! Does anyone know what it means when the motor keeps running? At stop lights, drive thrus etc. 2010 Prius with 253k miles.. Just bought it and it usually drives like it's brand new. The charge bars fill up fairly quickly and stay up. Will only drop if I'm cruising through a parking lot or two looking for parking. Motor only acts up every few days and stays running until I manually shut her off.

Thank you

What does that mean ?

The gas engine (ICE, Internal Combustion Engine) tends to run a lot more sometimes during extreme weather.....either too HOT or too COLD.

But that is also a possible sign of the high voltage hybrid battery going bad.
IF.....you still have the original hybrid battery in place.....this might be bad news.

Thank you.. Would I be getting a check engine light or light from the dash if high voltage battery is going bad?

Yes eventually. But sometimes you notice other symptoms before the battery gets bad enough to trigger any fault lights.
