Lately the water drips after from the Sun glass compartment after heavey rain.(right next to the rear view mirror. My car as sunroof both in the front and the back of the car. The Maxima had this problem and my car did had a recall and the sunroof was replaced. The problem just came back after 4 years.
A sunroof has drain tubes. If one or more of them clog up, water can get inside the car. Supposedly you can use string trimmer line or compressed air to clean them, but I have no experience doing this myself.
I went and looked at this TSB (not a recall) and you are going to have to do the same thing that was instructed to be done previously. That is you will have to lower the headliner and locate where the water is comming in then apply the sealant as instructed.
