My vehicle has water leaking in it when it rains on the passenger side

I keep getting a code that states that my truck runs with a low engine temperature. Plus my truck has had a leak from some where around the lower windshield that is causing electrical problems and soaking wet floors! We had a mechanic look for the leak and try to fix this issue but was unable to find the problem and we were also told by a few dealership that they have seen a lot of h3 hummers with the same problem! Also we are having issues that causes the traction signal to come on regularly and it causes my truck to lock up. It has almost caused us to wreck several times! It's very scary to drive my hummer! Every time we have any of these problems we are always in motion and it's always on the highway when we are driving at higher speeds. It never seems to happen while driving around town!! This has been continuing going on ever since we purchased this vehicle in august 2014

The radiator has a crack in it which is a very common issue...needs to be recalled. My h3 was idling rough and would shut off. Had to replace throttle body and solenoid. The anti-theft acts up and the h3 won't start have to wait 10 minutes. The AC blower and connector burnt paid for it to get fixed then the recall comes out 7 days later....still haven't been refunded for that. I have all the issues on my 2007 h3 that should all be recalled and fixed at gm expense. Sunroof drains get clogged all the time and have water leak onto the floor which makes the ABS light trigger on and off. Issue after issue which gm doesn't take any responsibility for. It looks like it's time to sell the hummer h3!!

There is a known issue with this vehicle leaking I noticed it when it was raining that rain would leak through the on star microphone as well as through the front the driver and passenger doors and make the carpet like a sponge: https://youtu.be/ennnfwkhqwo the video attached to this link shows a prime example. If you read the comments it would show many customers of been affected with the same exact model vehicle. Also this video shows another example of water leaking through the on star microphone. Https://youtu.be/aqhyfoosmxg it is too expensive to have to pay $130.00 for them to diagnose a manufacturing flaw that multiple owners are going through. Please set a recall for this vehicle for them to resolve. Again it is a 2006 hummer h3. Thanks in advance.
