I have an 07 NNBS truck and think the sunroof is leaking. I keep hearing water rolling down the B post lacated between the front and rear door. After the last rain, I opened the sunroof and found lots of water around the inside of the sunroof towards the front of the metal etc. Please let me know if this is normal or not. I have never had another vehicle with a sunroof that allowed water inisde the sunroof at all.
