    I have a 2010 Prius 3 which the cluster at first showed signs of failure, weak lighting and sparking noise at some display modes. Right now the left-side of the cluster isn't working, where the speedometer, fuel gauge and instant fuel consume shows. (The mirrored cluster). What could be the issue and is it possible to replace just this component of the cluster?[​IMG]

    That's only true with 2004-2009 Prius... And while that could be the problem here, It also could be something else entirely...

    Do the warning lights to the left of the cluster still light up when you start the car?

    Yes. Only the Speed/Fuel/MPG screen doesn't work.

    Hi! Wondering if you ever found the fix to this. I am having the same issue and can only find DIY fix info for gen 2 prius.

    In re-reading this I suspect you'll need to find someone that's able to replace rather than repair this part... The main problem as illustrated in discussion above is the instrument failure in Gen2 2004-2009 Prius is so common that its hard to find info specific to 2010-2015 Gen3 Prius. After doing some research just now it seems like replacing the part is only way you repair it. Hopefully the odometer is not integrated into this part and its an easy swap by pulling it from a car in the wrecking yard for cheap. If the odometer is connected to it, then you'll need to reprogram it and that will probably cost a bunch of money from someone who is able to do that.
