24 trail boss diesel leaking sunroof help

[Ndean9142usmc]

What’s happening fellas. I’ve got a 24 Silverado trailboss, bought new little over a year ago, roughly 22 k miles. Having an issue potentially with the left driver side of the sunroof leaking and staining the headliner. Already made 1 trip to the dealership where they said they can see obvious signs of water getting in but after 2 hours of pouring water on the sunroof they were unable to detect where the water was leaking in from. They made sure the drain tubes weren’t clogged with debris and i verified they weren’t by pouring water myself directly into the track and saw the water drain from underneath the truck on both sides. After some rain last night and this morning, the headliner was soaked yet again and bringing the truck back to the dealership Thursday. When the sunroof is closed and you look at from the roof the driver side front corner appears to sit much lower and recessed than that of the front passenger side, possibly the sunroof is out of adjustment and causing excessive water to leak through on the driver side?? Anyone else experience this issue with any luck of resolving it? Any help and Input would be greatly appreciated. Thank you in advance.

It may also be the XM shark fin antenna. Was with mine. They couldn't replicate in there water dosing machine. Told them to keep it over the weekend. It rained Sunday into Monday, then they saw it. Just an idea to look at, as well. Good Luck.

Thank you very much for the insight, I’ll definitely mention it to them on Thursday, they claimed to have checked during the first visit about a month ago. But maybe they can check the seal around it and make sure it’s tightened down properly.
