Edit: Issue resolved (dimmer switch turned all the way down), review posted: Review: 2012 Toyota Prius v Three - National Cars | Examiner.com Hi all, I review cars for Examiner.com, and I'm right now in a Prius v Three on loan from Toyota. I was wondering if anyone was familiar with this issue my test car has been having: when I pass through a tunnel or under a good-sized overpass, the speedometer and adjacent displays cut off until I'm back out. I shot a quick video of one such instance, but the system won't let me post a link as a new member. Take out the spaces (but not the underscore) of youtu. be / r8k01wmxn_Y Thanks!
