Yes 3rd gen cars are not as
Yes 3rd gen cars are not as reliable as 2nd gen. I owned a 2008 Prius and it was very reliable. My 2013 Prius 3rd gen started using oil at 102,000 miles and Toyota dealer said that it needs a new engine. They said it is a common problem with 3rd gen Prius and that the problem is with piston rings that need to be replaced. We had a car since 2014 and changed oil every 10k miles as per Toyota. Apparently if we changed oil every 5k miles the problem might have happened later in the life of the car. I would not keep gen 3 cars for as long as I would gen 2 cars. This is from my personal experience owning both gen 2 and gen 3 cars.
