How Much Water Accumulates On the Roof of a Yukon XL

[Joseph Garcia]

How much water accumulates on the roof of a Yukon XL during a long rain storm?

Short Answer: A freakin' LOT.

Long Answer: Yesterday it rained for the entire day with my Yukon XL remaining outside, something that I do not usually do. With today being over 60 degrees in NH, I decided to put down the windows, open the sun roof, and go for a nice Spring ride. Leaving my driveway, the road heads downhill, with a stop sign at the bottom. When I leave my house, I drive slow and quiet, so that my exhaust system does not bother my neighbors.

As I approached the stop sign, I braked the truck to slow down and come to a stop. Suddenly, a waterfall of water comes pouring down from the open sun roof above, onto my head and down my neck and body, all over my center console, and all over the passenger seat (So good that my wife was not with me!). I was completely soaked from the waist on up.

Lesson Learned: Do NOT open the sun roof after a rain storm, without driving your truck around a bit before doing so. We can add this to our accumulated knowledge base.

It is actually a bit funny now looking back, but I can assure you that it was NOT funny at all, at the time it happened.

Lol, don't mean to laugh, I'd be pissed--at myself. Hopefully you dried it up quick and nothing got ruined.

Sounds like you figured it out. I was gonna say based on how much comes in my window on a right turn seems to be around 5 gallons give or take.

Sorry Joseph, I had to stop reading about 3 lines in....

You are right, Tony. There was nobody to blame, but myself. And, I was pissed, initially.

Fortunately, I always keep a few rags in the truck, and I was able to quickly mop up the water on my seat, the center console, passenger's seat, and wherever else it was. I let myself air-dry, as I drove around with everything open. It was cold as Hell, as the water on my body evaporated, but that was my penance to pay for my stupidity.

Kuddo's for driving with your neighbors in mind. And I know for a fact that there is a lot of water up there...................mine was the drives window and my wife was there to laugh first.

Just when you thought you couldn't get anymore awake, bam.

Wife: honey, why are you soaking wet? It quit raining yesterday?
Joseph: ummmmm

My wife would surely laugh (and she did, when I got home and told her).

She actually had a similar, but more sinister, issue with a Honda Accord that we used to own. Apparently, the drain tubes within sun roof interior assembly were clogged, along with a minor leak on the gasket seal of the sun roof glass itself to the sun roof opening. Our house at the time had an upward sloping driveway, and during successive rain storms, water would collect within the interior assembly of the sun roof.

The interior assembly would fill with water, and then when my wife would go out in the morning to go to work, fully attired in her business suit, when she got to the bottom of the driveway and and turned onto the road and accelerated forward, the accumulated water would come pouring down on her head. Fortunately for me, I was already long gone on my commute to work by then, so I was not there, when she had to go back into the house, fuming, to change her clothes and try again.

So, she saw my episode with the Yukon as some type of poetic justice.

I don’t see that many here in So Cal that open the sunroof in their NNBS lol. GM did get the sunroof mechanism right though. Not too many issues w/ them.

Oh yea, that water WILL wake u up, especially if it’s cold. Rolling through a particular stop sign is the only way to avoid a full XL flood. [emoji12]

I miss the good 'ol days when there was a water channel on the roof edge. ( station wagons)..
That said...... I back out of my driveway and stab the brakes to run the water off the roof at rear.
Then stab the brakes at my 1st stop sign to complete the water removal process. What a pain.
But... We live with it

I agree. I never got wet from water coming in the window of my 78 C10.

I think some water accumulates around the sunroof seams as well.

Same problem as JG only worse..."Brain Freeze"... weather was sunny and clear.Took my 19 Denali out and opened the roof for the first time to enjoy the ride. Left it parked in the drive and you guessed it-now it's pouring roof still open-every thing soaked.Anyone know of a way to rewire roof to auto-close when ignition is turned off. Use to have a Tahoe with Holandia after market roof with that feature and loved it.
