Horror story time. I got a 2015 V60 in back in 2016. The car had only been used for one year but had high mileage ~40k. I take good care of all my cars. I don't drive aggressive. I did all my service at the dealer. I mentioned to them that I have to add oil between oil changes. As I neared 80k miles the frequency of the low oil warning got up to two quarts between oil changes and I told them again saying that this seems like too much to me on such a new car. They did diagnostics for 3 visits, measuring the oil each time. We did a cleaning routine they said would free stuck piston rings and fix the problem. It did not. Then they did a borescope. They said the inside of the cylinder walls were damaged, allowing oil to blow by. They sent the images to Sweden and Volvo said to replace the engine. I was shocked. I've driven a Ford to 400k miles and I've never heard of anyone replacing an engine for any reason. The car was out of warranty but Volvo corporate offered to pay half of the cost. This makes me think that it was a defect or somehow their fault. I've read something about piston ring issues on this model of car. What is going on? Is this a common thing for this year\model? How do I know my new engine won't be ruined in another 80k miles?
