I had a 2007 Volvo XC 90... Worst car I've ever owned. The angle drive that controls the AWD broke at 75,000 miles, then because that broke the computer freaked out on every turn and made the car quite dangerous to drive. The seat-move button broke. The muffler rusted through in a dry climate. I somehow bent my lower rear control arm while on a very mild dirt road. The frame was built very weakly. You need a special proprietary tool to change the oil filter. No one ever has the air and oil filter in stock. The wheels were too wide for the wells so the turn radius was crap. The engine is mounted transverse and canted over so sparkplugs are terrible to get to. My main seal developed a leak. The radiator cooling fan died at 60,000 miles and cost $1500 to fix. In any other car it wouldn't cost more than $400.
Overall an absolutely crappily designed car. It wasn't just me. A friend had a 2005 XC90 where the transmission completely came from together at 80,000 miles. They had to send it to a junk yard, wasn't even worth selling.
The XC90 is total junk. I have no experience with their other vehicles and can't comment on them, but I will never be buying Volvo again.
