Been reading a lot on the web about this: problems with 3.2L I6 oil consumption in 2010-2011 XC90s (and other years). It's a common issue that Volvo apparently knows about and is addressing through warranty repairs.
Now, the issue is close at hand because our one-owner 2011 XC90 with 72K miles (FWD NA 3.2L) has the problem. During services, the car has been monitored for quite a while because of high oil consumption and the dealer finally has concluded "the pistons are bad," which I interpret as defective piston rings.
The dealer is engaged (car has only been serviced there) and says it has submitted a warranty claim for a new engine. The other alternative is to replace pistons and rings in the existing engine. Either way, the car is going to be laid up for a while.
A new, replacement engine seems the best way to go. Any downside?
