The body is defective in keeping water out of the cab. Water intrusion into cab causing moisture build-up and damaging interior and electrical components. My safety is at risk due to the electrical components in the cab that run the vehicle could cause electrocution or cause the vehicle to fail while in use. No they have not reproduced the problem. Yes, GM Collision center and service center (three separate times) have seen the vehicle and the video of the leak. I informed them of the TSB5396 of the known manufacturer defect issue. No warning, problem was first noticed in May 2023. I found my interior completely soaked one morning. I have waterproof marathon seat covers and they are soaked thru to the seats. Checked all windows to make sure they were up and the door seals were shut, everything was closed. Assumed that it was a fluke, followed up by checking the next morning and found the headliner dripping along with a soaked interior again. With the electrical seats and all the electronics in the dash I am concerned about that much water and moisture being in the cab might electrocute me or cause malfunction while driving. Besides the fact that moisture causes rust, mold and mildew that are dangerous to your health to breathe in.
