    I got a "Check Hybrid System" warning in my 2011 Prius while driving home. No other warning lights, and the car seems to be running normally. I have turned it off and started it right back up with no trouble other than the warning light.

    My usual mechanic doesn't do hybrid system stuff, so I took it to the Toyota dealership. Again, no issues with driveability.

    Toyota guy says a bottle of brake fluid stashed in the hatch bin has leaked onto the battery. Now, there was indeed a bottle of brake fluid stored in there, and I can certainly believe that it may have leaked. I'm having a harder time imagining how it made its way to the hybrid battery.....
    Toyota guy says pricing to take out the battery and clean it up will *start* at $800!! o_O He also says it isn't safe to drive the car, but that may be a tactic to ensure that I agree to let them do the repair. He also couldn't tell me what codes it was throwing-said he didnt have that info in front of him (phone convo)

    What on earth should I do to avoid being taken for a ride by the dealership? Maybe they're on the up and up, but I am def. operating from a place of skepticism. And I DEFINITELY don't have an extra $800+ to burn unnecesarily. What questions do I need to ask? Does $800 seem reasonable for that kind of work?

    The standard way to “check” or diagnose the hybrid system is to use an OBD tool called Toyota Techstream. If the Toyota dealer did that, he would have a precise reason for the light.
