We have just purchased a new 2018 envision. We are experiencing water emptying we the doors are opened. Door are suppose to drain but not only when opened. We took it our local dealer and showed the service manager and as noted on this site others with same problem, was told they were not aware of this occurring with any others and would send the video we supplied to GM. This issue needs to be investigated and corrected as we as with the others live in a cold climate and freezing is an issue for 4 or 5 months a year. This situation is also promoting environment for rust to form more quickly than it should. My request is to anyone with this issue to post so we can get an idea how widespread this issue is, and if you don't have this problem , what is the difference between our vehicles. Thank you

Our 2017 Envision holds water in all four doors and will not drain unless you open the doors
