when the odometer turned to 69500 = or less started hearing a noise I though it was coming from under driver seat. Took my car to the Volvo and they told me it needed a new eoc unit at a cost of over $5000 dollars. I called the Volvo corporation and also I read on the internet that some of the Volvo xc90s had that same problem, but my financial aid was denied, because I had an accident in 2010. Is any one else having a problem with Volvo xc90 Thank you vsymons
