I had the same on my 2011. Took it to the dealer and the front drive shafts were replaced; or something to that effect. There is apparently a TSB on the issue. I also had a popping/clunking noise in my front end and the dealer also replaced some suspension parts, think the spring perches; or shimmed them up. Anyway, has taken most of the vibration out. I just have some very light vibration in the steering wheel when at a complete stop. Kind of sucks..... I had an '09 V70 3.2 and had no issues what so ever. It was quiet, solid and smooth....2012 XC-90 3.2. Experiencing vibration during moderate acceleration from zero to 50MPH. Feels like left front drive shaft vibration. Total mileage 33000.
Tried SS thread search but could not find any related posts. Inputs would be appreciated
