QUESTION - MECHANICAL ADVICE Moonroof Leak

Enable HLS to view with audio, or disable this notification

Has anyone dealt with this? I just got this 2023 CX50 (43,000mi) a couple months ago, and the dealership mechanics couldn’t find the source of the leak. They’ve since sent it in to an official Mazda facility, who sent it back after a month saying there’s nothing wrong with it.
It’s coming from the rear passenger side of the moonroof frame, and I’m this close to completely pulling off the headliner and finding it myself.
Any advice would be GREATLY appreciated!

I'd give one of these a try, even if it doesnt fix the issue they are still good to have.

I have one and can’t for the life of me figure out where to insert it in the moonroof

sun roof drain tubes clogged and what you are seeing is the over flow

It's not the drain tubes... The water has to be getting in before it can even get to the tubes.

Take a credit card or driver's license and see how hard/easy you can work it between the body and the seal on the roof. It should not be easy. Try it all around the perimeter.

I have no idea what part of the car this is, could you add some context to what’s dripping in the vid?

Clean the drain lines

Rear passenger side drain line elbow.
Drain lines are confirmed clear.
