Crankcase (pcv) Problems of Volvo XC90

Without any warning, the motor suddenly dropped from 60-65 mph to 35-40 and would not accelerate beyond this- I got a warning message after this happened "reduced engine performance". Research on this later told me that this was "limp mode. " I was on an expressway and other vehicles around me, including many large semi trucks, were driving at high speeds. Fortunately, I had just come out of a toll plaza and was in the right lane so I was able to get out of the way quickly enough to avoid a collision. I had to have the car towed since it was not safe to continue to drive at such a slow speed and I was far from a suitable exit. My repair shop identified a problem with the throttle body and the pcv (valve) I see on research of earlier models of this car that there had been an "warranty extension" for this very problem. My car apparently was not included on this extension, but I find it suspect that I had the same problem. There may not be that many reports of problems like this with my particular model year because a large number of the 2006 Xc90s had early transmission failures and are no longer being used.
