I purchased an '05 XC90 V8 used but it was still under the original warranty and thank God. 1 week after I bought the car the engine started vibrating and the dealer replaced the balance rod, about an $8000 job from what I was told. 2 months later the alternator went due to an oil leak which was not found until the second alternator went 2 months after that. Now I am told that the tranny is probably going. The car vibrates between 40-50 mph. It will stop after a few seconds or if you give it a little gas. The dealer said just to drive it until it quits, not acceptable and not an option for me with a handicap child. I love my car, just don't love the repair bills and shop visits. I found a one owner '08 XC90 V8 with all the bells and whistles just like my car. It has always been serviced at the same dealer. From what I have read it seems like from 2003-2005 there are numerous problems with the transmission and other things in these cars. Has anyone heard of or had any crazy issues with the '08 model? Thanks for any input.
