Had some heavy rain last week and noticed a drop of water on the center of the dash. Felt around the headliner and sure enough a damp area in the center behind the rear view mirror. I pulled the center roof trim and hit the entire outside area with a pressure washer for what I think was a generous amount of time. No leak 😡. Next step is running it through the car wash. Sunroof drains are clear. Also I had the headliner down and checked / resealed everything 6 months ago. I had the sunroofs open the day before the rain. Hoping maybe something wasn’t completely sealed during the storm. Putting this out there to see if anyone has any suggestions and to document what I find to help someone else if they have the same issue.

 

What you may find is that you have one of two issues:
1)there is a gap in the roof rack rails where they turn to meet the from of the car. As if they forgot to weld there. You may have to slide the trim piece forward to see it. I had a lead that dripped from the pillar to the mirror in heavy rain. I put some silicone sealant in that area and have nit had a leak since.
2) The drains for your sunroof are broken or clogged. The connectors that go from the drains down thru the pillar are plastic junk. they break or wear out easily. Open the sunroof and get a flashlight and look down in the front corners of the sunroof assembly. Blow out any junk you see.
If it still happens after you try my suggestions, it is very likely that the connectors are broken.

 

I had this problem after my windshield was replaced. The solution was to add a thin layer of silicon sealant between the roof and the upper windshield rubber molding. I used a plastic trim tool to pry it up, and then slid along while squeezing the tube of sealant into the gap. Worked great!

 

Thanks Tim that’s what I’ll try next. I went through the car wash no leaks. Going to hit it with a hose one more time before I put the trim back on
