I have a 2018 LS 500 driver door leaking. Could this be a weatherstripping seal? Today raining I notice wet from the driver side above head area always down and dripping around my left foot floor. Sunroof completely drive inside, could it be weatherstripping seal?

 

It could be a clogged sunroof drain. Especially if the A-Pillar is wet. If you have the panorama sunroof, I would advise having the dealer clear the drain-lines.

 

OK went to the dealer. The initial check for the leak is $219.00
It was the Sunroof rubber molding deteriorated and need to be replace.
The cost is $1459.59. Wow!!! that's crazy.
Check the part # 63251-50070 only $68.00
Unbelievable!!!!.

 

Curious, is that the fairly thin, fairly soft rubber seal that is in front of the sunroof panel, one you can see from outside top of car and goes from left to right? If yes, is it torn?
Best,

Something must have damaged the weatherstripping.
I have owned more cars with sunroofs than I can count and never had a leak.
Could it possibly be repaired? A picture would help.

 

I lost all trust in Lexus Dealership and Lexus certified mechanic. All vehicles with sunroof tent to leak, but the drain suppose to drop the water onto the ground not into the floor. Instead, I got a quote for $1459.59 minus a $219.00 initial check for the leak.
The part itself only $70-$80.
Went to local shop cost me $20 to blow the high pressure air into the drain and it stop leaking into the floor.
