Yeah, once I’m out of this headache that may be what I look into as I never use it, I purchased my truck preowned so didn’t have a choice of sunroof or not

So my truck has been at the dealership for a week, so far it has been determined that the driver side front sunroof drain was in fact missing and appears to have never been installed from factory, and the water that had entered the truck for the past 5 yrs has caused corrosion to the driver side fuse panel and fuses which are currently being replaced, at the moment the dealership has been treating this as though my aftermarket warranty will not cover this and warning me of the costly labor that is accumulating. for something that is an original part of the vehicle that was neglected and missing I would think should be covered especially since my aftermarket warranty mimics a factory 5yr new car warranty. I am in need of my truck back, but it looks like this could be a long drawn out fight where fingers are pointed and no one wants to own, I don’t think this dealership should be stuck eating this bill, but wish helping me get this covered by manufacturer was on there list of things to do for a customer

@Unhappy client check your sunroof drains are actually installed, my 2020 seems to have never had the driver side drain installed at all, when I bought my truck I only had noticed the rear window leak and after some searching decided to do the fix myself to avoid damage to the headliner. also read that the fix from the dealer was temporary for many that ended up with leaks again… my fix is rounding 18 months.

Thanks for the info @newdude I really appreciate it, I already ordered the drain tube, but now I’m thinking I should let a dealership install this as I am now afraid that the prolonged moisture to the fuse box on the driver side could potentially cause an issue later on and it would at least be on record that the truck was missing the hose in the first place.

I had originally posted this in an old thread to see if I could find any users with same issue. All the rain I got in the last few days in the northeast and now the issue appears to be worsening and I now have my beautiful truck missing panels so I can keep my driver side fuse box dry I might even have to have the sunroof wrapped as a temporary fix.

Sad thing is its only a $7-$8 part…and drips down into a location of the truck that can cause thousands in repair…I have trust issues with dealerships and would attempt to add drain hose myself but can’t seem to find an schematic or diagram showing where the hose routes down to… if anyone has any idea, I would appreciate it. im out of dealer warranty and my extended warranty is iffy about water issues even though I’m pretty sure this is a “manufacture error” I mean its completely missing.

I have owned my 20' Sierra SLT for 2 yrs and have always noticed some small amounts of water on my driver side rubber mat, I initially thought it was from windy rain making its way through the door seal, but we have had some heavy rains this year that I noticed the water stain on headliner above the driver A-pillar, and noticed the water dripping down behind the dash, near the obd2 port...originally thought the source could be the shark fin antenna, so I partially lowered the headliner and ran a hose over the truck, only to realize the source is the sunroof drain...HAS NO DRAIN TUBE ATTACHED, looked to see if it had disconnected but it is not installed at all, anyone else have this happen?
