Here are a couple of pictures
That is the only place. No wet carpet, no sun roof. It has been frustrating not being able to determine source, even with lots of water test.Is that the only place you've found water?
Is the carpet wet anywhere else?
Do you have a sunroof?
Here's what I would try: Put a bright light in the well at night. Crawl underneath and see if you can see light anywhere. Or conversely, put the light underneath and see if you can see any light in the well.
From what I could tell, just sitting, on a level driveway.So did you discover the water after driving?
Or the water pooled up even just sitting there parked?
Yep, thank goodness we are under warranty. Chev dealer has had it twice with no success. The saga continues.Maybe a leak from the roof/roof rails or maybe a faulty window seal or something?
This is gonna require some investigating for sure though
How about pulling everything out of the well, have someone sit inside watching while you use a hose/pressure washer simulating rain on various parts of the car (roof, side windows, tailgate)? I would venture to guess that if it is happening while parked that it's not leaking from below. Plus if it was leaking from below it should also drain as you said there was 2" of standing water.Thanks, I have already tried both methods, no luck. I am looking for some water soluble paint that I can paint inside the well and hopefully when it leaks, it will leave a line in the paint.
I ran into this problem in my 2008 Chevy equinox. I believe the water was going under the rubber seal of the lift gate. I never alleviated the issue though. I just drilled holes through the floor in the bottom of the tire well.A few months ago, my wife had a flat in the rain. After she got home, I was getting the flat tire out of the spare tire well and noticed about 2 inches of water. Thinking that the flat tire may have filled with water until she got the car stopped, I just dried it out and forgot about it. About 2 months later I was checking tire pressures and noticed about an inch of water in the spare tire well. Took the 2018 Traverse to Chev. They could not find any source for the water so I brought the car home. About a month later after a medium rain, I checked again and lo and behold, water in the spare tire well again. Back to Chev. but once again they could not find a problem and they even left the car outside during a 2" rainfall, sitting level the same as my driveway.
I am puzzled as to where the water might be coming in and how to determine the problem. No idea why the car did not leak for Chev dealer. They even sent me videos when they opened the well to show, no water.
Anyone else run into this?
