2022 Yukon driver side floor soaked!

[Hiebs]

I just purchased a new 2022 Yukon Denali less than a week and a half ago. Both times it has rained I've had my driver's side floor soaked! After the first time I took it to dealership, they said the blew out the drain lines and thought that should fix it as one had some gunk in it, they ran a hose on it for a period of time and said no leaks, dried my floorboard and sent me on my way. 3 days later it rains again, not a lot, but enough that once again the floorboard was wet. The first time water was dripping out of the sides of the upper console ( where OnStar buttons are ), last time no leaks there but floor still wet?? Pretty pissed I paid for a brand new truck and this is happening, it also seems this has been a known issue for a long time on various models. Has anyone found a fix for this, I'm worried that I'll have electrical issues down the road, truck has less than 500 miles and I already want to get rid of it!

have you taken it thru a drive-thru car wash? maybe sit in the passenger seat while going thru the wash and see if you can determine where it is leaking (approx)
sometimes what happens is the front windshield is not sealed up properly allowing for water intrusion, a drive thru car wash may help you determine where it is coming from.

Sure sounds like sunroof drain issue..but could be seal on windshield, roof antenna, or sunroof. See if the roof antenna is loose or gapping at all.

There are TSB's for this issue that involves replacing and rerouting the sunroof drain lines.

This is a great idea.

Or try to position a water hose that’s constantly hitting the top of your windshield and running down the front and sunroof and sit inside and see what you see or hear. Then take video and pics and share with dealer.

I know that sounds like a lot of work for your brand new vehicle purchase, but at least you’ll know.

I'm having this exact same problem on my 2012 Tahoe PPV.

Might want to post that in the NNBS section if you're looking for responses or suggestions.

Just happened to me and have an appointment to get it checked out, now my dashboard is blank...!

Good luck! Mines been in several times , each time they give me a story and say it's fixed yet it's still leaking, it's going back again next week.

@Hiebs mine is still having the same issue as well. Same leak spot in the upper console too. They extended the drain tubes according to a TSB, but that didn’t help. Im starting the lemon process, using the BBB autoline, but might switch to an attorney.

Bummer deal. This happened to ours as well but never had the overhead leak. The TSB that extends the drain tubes was the fix ours needed. That was around 3k miles (didn't rain here for the first couple months we had it) and the yukon now has 22k, still dry

This was shared on another post but think it could be the issue. I pulled down my overhead console and found the exact issue described in the video.

hi, i have the same leak the good people who sold it to me didn't say a thing about. Drivers floor mat. Any other suggestions is greatly appreciated!

If it's under warranty still I wouldn't worry about it as GM will fix it at no cost to you. Out of warranty I'd be pissed. I also think anyone that owns one of these new models without some form of warranty is out of their minds. Way too much high tech shit on these to go wrong that's both expensive and your average indy shop won't be able to fix.

 

[Hiebs]

Been to dealer 5 times now, they say they can’t find the leak, I’ve shown them videos of water pouring out from under the drivers side dash, but that’s not good enough, they keep telling me they need to see the leak to see where it’s coming from

 

[Tahoe14]

Tell them to hire a water leak expert as the Dealer seems incompetent. Maybe reach out to GM no customer service.

 

[Chad G 1979]

They know where the water is going, so that should natrow down where its coming from. Go to a different dealer if these guys are too lazy to figure it out. Using a garden hose and running water over the vehicle in typical locations where it can leak would be a great trouble shooting tool for them to use. Sounds like this dealer service dept is lazy, and the service manager is incompetent. Its a door seal, sunroof seal, improperly fitted windshield, broken or plugged drain tubes from sunroof, or drain from bottom area of hood. Just takes time to work on it and those folks dont want to bother.

I have a 22 Yukon Denali, and the drivers side floor is soaked completely under the all weather mat. Pretty annoying that gmc has engineered such a lousy rig in my opinion. I had a cayenne before this and had another kid so had to get a three row suv. GMC is no where near the level of quality/engineering for the price of these Denali Yukons.

When we had our leak problem the local dealer had a test unit of some sort they used to spray water on it from above. They actually dropped it on our Yukon and scratched the driver front fender but fessed up to their mistake. It was so minor we never would have known but ended up getting an $800 credit out of the deal we used to buy better tires

Did they find the leak?
