All new Prii come with roadside assistance. Toyota doesn't want unhappy hybrid owners. They'll take you to the dealer, I'm sure, and make sure all your needs are met. Because Toyota wants to be sure this technology has a good name.

Unfortunately most major work MUST be done by a Toyota dealer/Prius Tech. Otherwise you're running a risk of someone really messing up your car and/or getting electrocuted. Minor things like oil changes can be done elsewhere but for warranty's sake most people go to the dealer anyway or do it themselves and get the warranty book stamped.

All in all there are very few problems with the Prius. Many (I stress MANY not ALL because some people just do stupid things to their cars) problems are covered under warranty, and in that case you'll have to go to the dealer anyway.
