2021 Trailblazer Leaking after heavy rain
I been going through this issue for months. I been doing my own investigation using a water hose. My final conclusion so far is the hatch gasket. I sprayed water on small areas at a time and the leak started. I decided to add extra gasket around the original gasket (temp fix) 2 days of rain and no leak. Only cost me a few dollars for gasket.
