I recently learned the issues with owning a Volvo AWD Cross Country. I purchased a brand new 2001 Cross Country 5 weeks ago. This past week I ran over a big piece of metal on the highway. This piece of metal puntured the rear tire. The car only had 2500 miles on it. Ironically, I received a link to this web site the day of the incindent. I read some of the issues with riding on the donut with the AWD. I made sure to maintain the 50 mph all the way home and to the dealer the next day. Upon arriving at the dealer, the service manager met me and explained that I would have to buy all new tires for my brand new car. He also explained that this was ultimately my choice, but the warrenty could be voided if all four tires did not have the same tread. I had not even made the first payment and had to spend $650 on new tires. While waiting at the dealer, I did give a new cross country owner the bad news. I also instructed the sales person(who said he had never heard of that). I wished I would have known this prior and I would have just bought the regular wagon. I now have 3 good Pirelli tires with only 2500 miles on them. What a hard first lesson to learn. Add me to the list of upset Cross Country owners.
