Failures no, but I see the frequent trend of low mileage, newer vehicles, with oil consumption issues. Some are blamed on low piston ring tension and/or ring coking but some are also blamed on worn cylinder walls and piston rings. Manufacturers are experimenting with coatings to combat the low vis oils but, as I have seen, the coatings don't last very long.
I owned a late 80's BMW with, what I would call, an experimental "high MPG" engine that used low tension piston rings. To compensate, this engine still called for a 5w40 grade oil and got great MPG with no oil consumption.
