Toyota. I own a Prius and can tell you it's been the most trouble free car I've ever owned. The downside is it's a hybrid and those batteries don't last forever. I had to replace the traction battery at 78K at a cost of $2300, one year out of warranty. Although Toyota did tossed in $750 and the dealer took $400 off the battery for me. Due to people owning hybrids longer than the manufacture expected Toyota has had to increase the warranty on the hybrid system to 10 years and I think it's either 120K or 150K miles. When I replace my 2010 Prius my next Toyota will be a non hybrid Camry.
