Hello AcuraZine,
I'm new to the community here and have an 07 TLS. As the title implies I have a water leak and looked in multiple threads about this topic and have done what is advised.

1. Check sunroof drain tubes. I used compressed air at the entry of the hole, on both front holes. I didn't have an smaller extension to go into the tube itself. I poured water and water comes out behind both front mud-flaps
2. Check seam sealer behind the roof molding. I removed the molding, cleared the leaves and other gunk. I found a small fine crack between the windshield corner towards the A-pillar. I JB welded that crack and put clear waterproof epoxy over it, to the top windshield seal, and behind the sealer that bulges out.

Results, I still have a leak what seems to start from the front of the grab handle to the headliner down the mating edge of the headliner and A-pillar. If unattended to wipe it off the water it will drip to the left bolster of my bottom cushion of my seat. This only occurs when it rains vs a car wash or spraying water in the general area.

Other observations, I noticed upon raining the sunroof gasket on the driver side is slightly below the roof line and water semi pools in the area compared to the opposite side. Additionally, the rear is slightly above the roof line. Not sure if this has any substance to anything? Anyways I'm flustered and not sure what to do next. I have everything disassembled to drop the headliner at the corner to observed anything when it rains next. Help is appreciated!

Can you share some pics of the areas you're describing?

The fact that it's only rain is telling, and makes me think it still has something to do with your sunroof. Can you rig up something to completely block/seal the sunroof, and then dump a few gallons of water on the car and see what happens?

 

Yeah I thought about putting duck tape around the entire gasket of the sunroof itself before another rainy day. Another step was taking a small scrubber that can go into the drain hole and push it down with some welding rod

Most likely EasyLoveRDX was asking for pictures of the interior and the places that were getting wet.

 

It would start essentially just below the grab handle as shown in the picture and stop at the crease where the headliner and A-pillar butt up to each other.
