    Hello! Happy to be a part of the Prius family.

    I just bought a 2010 Prius Five with the Solar Roof package and I have two issues so far.

    1. The trunk/hatch won’t open unless I reach in through the back door and manually unlatch it. I have tried unlocking with the doors, the key fob, having all doors open, closed, etc. The button on the back refuses to work.

    There is also an aftermarket “Compustar” system that can remotely turn on the car, lock/unlock, and open the trunk. All functions on this work except for opening the trunk.

    2. The rear wiper doesn’t work. I honestly don’t care much about this. I am considering doing a delete anyway. I just added it in in case it’s relevant to the trunk not working.

    Other than that, great car! Everything else seems to be working! Regular locks, key fob, front wiper and liquid, etc. all works as new.

    Oh, and I also pulled all the labeling off of the back to see if any wires were disconnected, and it looks like everything is connected fine. I unplugged and plugged the trunk button wire back in and still no luck.

    congrats and welcome!

    hopefully just a fuse, or wire in the hatch. check the fuse continuity first, if that is okay, check the hatch wire connector for corrosion. if that's okay, you probably have to pull the inside of the hatch off to get to the wiring.

    Welcome. Sounds like something happened to the cable going to the hatch. Most likely, either mouse damage or something got left disconnected during the Compustar installation.

    As long as you are doing continuity testing, test the button itself when you have it unplugged. I'm hypothesizing that the previous owner may have been lifting the hatch by putting full force on the button after it unlatches, instead of moving back a half inch and using the stronger part of the back trim to lift the hatch..

    Perhaps the compustar system is defective, or there is a wiring problem at the hub
