Had my XC 90 for about 8 months now, got it at 30K miles, now I’m about 54K, last weekend there was a leak to the inside through the plastic part underneath the mirror. Very bizarre, Volvo is asking $650.00 just to run a water test. Did anyone had that problem?

 

What was the result of the leak? I just took a newly obtained 2019 XC 90 through the car wash for the first time and there is a leak in the same spot as you mentioned.
