I have a 2008 Prius with 110k miles. I admittedly know little about cars so any advice is appreciated. I had my engine replaced by the dealer July 2015 which was rebuilt and paid for by the warranty. This week my car started making noises and I brought it into the dealer, where I always have my maintainence done. After three 3 days, the codes came up that the transaxle needed to be replaced. Could this be related to the engine replacement? Seems pretty early for a blown transmission on a dealer maintained vehicle.
