In very wet conditions my 2006 XC70 sometimes emits a loud, screeching sound. I mean very loud! During dry weather it has not happened. First noticed it about 6 weeks ago when the car had 51k, happened again 9/26 with about 52.5k. Anyone had this experience? Any suggested solutions?
Thanks, Ksan

 

The accessory belt may be a little loose and when it is wet it squeals as it is slipping. The belt is too new to be worn, so I would look at the tensioner.
