    was there much clogging? if not, you may have to open the battery case. you can make a filter, or buy one online.

    You got to and cleaned the fan? If so, dirty was it? If not, you should do that.

    I believe this is the cooling system for the inverter not the fan.

    The plastic filter is from Toyota, about $14.
    The foam is from Lowe's. $3 or $4???? Cut to fit.

    "I believe this is the cooling system for the inverter not the fan."

    NOPE. Says right there on the dashboard: Hybrid Battery. If it were the inverter, it'd say Check Hybrid System.

    @NutzAboutBolts has a video on cleaning the fan; there's a link in pinned thread at top of this forum.

    Only thing: I wouldn't pull out the rear seat cushion, not necessary: you just need to reach through, remove one bolt.

    Perhaps, but your point about the inverter is still incorrect. ;)
    A myriad of things can evoke Check Hybrid System...
