My 3G battery keeps discharging when I am stopped. Any ideas?

    I don't believe this has happened under any circumstances. AC off temps about 74, rainy and obviously humid.

    Car in drive AC is off and it is still doing that. Now when I shift to Park and put the AC on it doesn't do that.
    I am having my anti lock, brake and traction lights on after I changed a RWB. This just started today, bearing change was Thursday.

    A 13, is five or six, a good life for a battery.

    2500$ and a new one, get it checked.

    understood, but i'm wondering if you are actually using battery, or if the arrows are the whole issue.

    so it sounds like a computer problem. hard to believe it is tied to the bearing replacement, but that would be the obvious place to look.

    maybe a loose wire or harness. if not, you'll probably have to read the trouble codes with tech stream, and look at the service manual troubleshooting tree.

    Thank you very much for the input. I am going tomorrow to have the wire on the bearing checked and the codes read. Have a great night and i really do appreciate all the expertise given on this site.

    I wonder if an ABS sensor is unplugged or it (or its cable) was damaged during the bearing replacement. Torque or Techstream could probably tell you if the car thinks a wheel is still turning (when it's not) and which one, but it would make sense that the repair caused the new problem.
    I had a shop replace a bearing on a different brand of car a few years ago and the mechanic did not follow manufacturer's directions for fastening the ABS sensor cable--it rubbed against the rotor and cut thru two days after the repair--I don't know if that same problem is possible on the Prius.

    They are called idiot lights for a reason. I am the idiot who was being too careful when i reconnected the ABS wire and didn't have it in all the way. The wait for the mechanic was too long so I bought an OBD2 and reset the codes my self. The battery issue also disappeared, so I am 1 happy Prius owner.
