What an interesting report ... AND a "comforting" one! My sister bought a base model, 2010 Prius "loaner" with about 11,000 miles on it from a dealership in Wichita, KS, just two weeks ago -- traded in a '97 Saturn with about 145,000 miles! -- and, prior to making the trade, had shared with me some concerns she has about the battery life and the expense in the event it needs replacing at some point. I'll have to let her know about this video report that you've included here.
180,000+ Miles on a 2003 It’s not the battery you need to worry about – however, the complex hydraulic braking system has some high repair costs.
