This has happened multiple times on the highway going 60 mph. And at slow speeds, last time on an entrance ramp onto the highway. The vehicle will shut off, as if the key has been turned off. But it hasn't been touched. Steering becomes difficult and I have to try and get off the road. Once I get pulled over and put it in park, it will start and run normally for a time. It most often happens when i turn to the right fairly tight. But not exclusively. Today after driving it approximately 120 miles with one shut off, my check engine light came on and it was difficult to get started again. This is absolutely a Hazzard to others and myself

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.
