I've just brought my 2008 XC70 back to my dealer for the third time for what appears to be a clogged sunroof drain that results in water filling the driver's side footwell during heavy, prolonged downpours. It even overflows the high-lipped Volvo rubber floor mats, soaking the carpets.
The Service Advisor believes that the occasional high pollen count and other debris may be the cause of the clogging. I live in NE NJ.
I park the car outside, in my driveway, at a slight nose-down angle (approx. 7%), and it was suggested that this may be contributing to all the drains not being utilized.
The dealer has been very helpful and apologetic and insisted that they keep the car for several days to remove the seats and carpets and thoroughly dry everything to prevent any mold or mildew from forming. They provided me with a very nice loaner 2010 V50 for as long as it takes!
None of my previous Volvos with sunroofs, 2 XC70's and an XC90 or my current S40 have sunroof drain issues.
Has anyone else experienced this problem?
