Today I noticed that it only shows 8 blueish bar,normally it should be 10.And the bottom 2 bars are purple.Techstream software shows no codes and all 17 cells with around 16.3v. Wondering has anyone encounter this before.It’s a 2015 with 107k kms on it.

 

That's really odd. I've never seen purple bars on the driver display, they're always blue from top to bottom. Better get it checked out at a dealer.

 

That's normal if you are looking at the Large Display. I miss the Prius when you entered into the Bars 7 & 8 they would all turn Green. Drop back to 6 and below Blue, drop down to the last 2 and they turn Purple.
