I have noticed that water is getting into both of my Montes rear lights. It seems to get in around the area of the clear indicator section. Only a small amount seems to get in the passenger side but the drivers side has more in and appears to go down further to the bottom of the light. Is this common and something that would be fixed under warranty? 

I have the same problem and when my car goes in next month for a service il mention it to the dealer then. Should be covered by warranty as its a defect in the light.
