    I have a concern about my 2010 Prius V(five). I've noticed some issues lately that may all tie in to one big problem.
    1. My ev mode will not work at all. My battery will be fully charged and not in "B" mode. Turning car off and on will not help.
    2. Engine will not turn off when coming to stops. Mind you when the battery is above 3 lines.
    3. Throttle response feels like it's in PWR mode(super sensitive) but the engine is laggy. If I floor it for a sec the RPMS are super slow to come down.
    4. The Eco line is quick to go in PWR portion and I'm not pushing it any harder than I was before all of this started. It seems like when I push the gas it skips the electric and automatically pulls from the engine.

    I plan on going to Toyota but wanted to post here first.
    Can anyone help?

    Overheated HV battery?
    Any sound from the cooling fan?

    No idea. I will listen tomorrow. Wouldn't I get a dash light for that? No warning light has ever came on.

    Maybe your 12V battery. I haven't experienced issues yet, but it can cause problems when it goes bad. They don't have a reputation for lasting very long.

    Have you been keeping the A/C on a very low setting? If so, in hot weather, this will drain the HV battery very quickly and will result in the symptoms you described.

    Yeah and on the MFD, when it's on the picture of the car, when the engine will not turn off the arrow from the engine to the battery is not there. Mind you the battery is half to full

    I've done this here in Phoenix every summer when it's above 110 degrees for years with no issues...

    Interesting. If I run the A/C on "LO," my HV battery will drop to two or three bars fairly quickly if I am in stop-and-go conditions.

    So nothing has changed but this can somewhat explain my problem. That battery is being charged when then battery is charged when it's not even low. And when the car acts when you drive it, it seems like it's using the engine only.

    I wonder if the electric mtr. has burnt out? Sounds like it's not helping the ice. H

    The only thing is that it's not all the time. It may do this a couple times a month
