Hello everyone. I have a 2016 XC-90 T6. I'm the only owner, and I've kept it serviced regularly. I currently have approx. 52k miles on it. Around 40 to 45k, my car started prompting me to add a quart of oil every so often. This seemed a bit odd, but I have owned and currently own German cars so I didn't think much of it. I figured it had something to do with running a little hotter than your average engine.
Before my warranty expired at 50k, I took it in for its scheduled service, and I gave them a laundry list of minor things that I wanted fixed under warranty. One of the things I noted was the oil consumption. BOY AM I GLAD I COMPLAINED. They told me to drive it another thousand miles and bring it back. I did so, and my car had used a quart of oil. They then said I had to drive it another 1000 miles and bring it back per Volvo protocol. After checking it out, they said the pistons need replaced. Luckily, this will be covered under warranty.
I asked if any other cars had this problem, and he said there are 2 XC-90s currently in the shop needing the same repair. He said it has to do with the oil rings wearing out/getting gunked up. Apparently Volvo recently changed their oil viscosity recommendation because of this.
Has anyone else had this problem? If so, what is you understanding of the cause. I'm a little gun-shy now to keep the car if it's going to need another major repair done.
