I have had Prii since 2001 (back when it was a sedan). Had good experience with them until recently: 2011 prius with 110K miles had to have it's engine replaced. Decided to do that instead of getting another car because anecdata tells me this was an aberration.

Did you have the EGR valve and cooler cleaned? It's the most notable issue with the 2009-2015 that leads to head gasket issues. Although, some say it's fine until ~140k ish, it could happen earlier if oil changes weren't full synthetic, yearly, or less than 10k miles.
