Hatchback/liftgate Support Device problems of the 2008 Saturn Outlook

Takata recall. . . . Water leaks into the car behind kicker panel on passenger side going directly into the fuse/relay box. It leaks in all door jams and the rear liftgate area. I have problems with my car not shifting. Throwing code p2723 which is transmisson pressure control shift solenoid e. I believe its due to water getting into the fuse box because there is a constant drain on my battery and when testing the fuses with a test light not all of them seem to be getting a good connection due to all the corrosion. Also sunroof leaks. All door circuits get wet. I have to dry evrything out before I can start it. The carpet smells and its full of rust. Common sense would tell you that this cannot be good from any aspect. Im to the point to going up to gm and making them look really bad because this is unacceptable. I cannot believe with so many common problems there is yet to be a recall. I hate gm and never will I ever purchase any gm product nor will I have anything good to say about gm. When all this occured my car was outside either in my driveway or a parking lot or driving down the road. I havr to cover the car up. The entire car. I bought the car sometime last year. I noticed this was happening about 4-5 months after purchase. Ive tried fixing it myself and I just fail everytime and its ridiculous.
