First off wanted to say hello and I am a long time GM/Chevy truck owner. I currently drive a 2017 High Country Silverado and it is my third one. Had some minor issues with the last one (Xm antenna water leak) but by and large all 3 have been good. The current one has 1000 miles and so far so good.

My wife's 2015 Crystal Red Suburban LTZ is the issue. Mainly it leaks water on to the drivers side floor.

First attempt to fix was replacing Xm antenna. Week later back at dealership with a leak.

Second attempt was a sunroof seal, no dice.

Third attempt was a remove and reinstall of the windshield with a multi layer seal to correct for a bent windshield frame. Been good for about a month. Good rain today, leaks again.

We bought the car GM Certified preowned with 12,000 miles on it about a year ago. Clean car fax, clean service history, clean auto check. One owner local car. We looked at it all. All seemed ok.

Anyone else ever heard of this many parts and this many attempts to fix without any luck? The bent windshield frame had to be a manufacturing defect but I don't know what to do about that either. This time I am going to demand that GM get involved again as the multi-seal windshield fix was supposedly their idea. The underside of the dash looks like a rusty old fence and the wiring is once again soaked in water.

Any ideas from the fine folks here?

Thanks in advance for any wise words.

Brandon.
