There is a free recall to fix the sunroof drains on the H3. Call the 800# for Hummer

Rear side fenders, check where they clip onto the body. Seals have failed and water can come into the rear of the vehicle through them. To check, you need to remove the rear plastic covers above the wheel wells. To seal them use some 3M windows sealer for automotive use or can use silicone sealant. Also, check your sun/moon roof drain tubes. https://www.youtube.com/watch?v=DbObpYU2lyo&t=1s
