I have a 2012 Prius V I
I have a 2012 Prius V I bought new. EGR failed just having got off a highway on a Sunday on a trip. Had to tow to a local dealer and arrange a fix. Just under 100,000 miles then and Toyota covered it. Last year, at about 150,000 miles my check engine light came on and my local dealer told me it was the head gasket and needed full engine replacement. I have my car serviced at this dealer at the recommended intervals and it had never come up. I opted for a 75,000 mile engine hoping to keep the car as long as possible. Only other major repair was one set of brakes this year at about 180,000 miles. Overall maintenance costs have been low. I have had the regular cleanouts mentioned. Wished I had known about these problems sooner, but still holding on to the car as parts I can see are aging well and so far other than those known problems it has been great for my uses.
