While I was driving down the road at approximately 55 MPH the windshield wipers stopped during a rain shower, while in traffic. I immediately had to pull off the road as I had problems seeing oncoming traffic.. Then the wipers started to move erratically and then started operating as fast as they could, with no control by the windshield wiper knob. After the rain stopped the wipers would not turn off. I had to remove the fuse to stop them. When I got home, I replaced the fuse but the wipers would not operate then. I took the vehicle to a repair shop. They told me I had wiper motor problems and that a recall had been instituted for the same problem by hummer but my VIN was not involved in the recall. I believe my problem is an extension of the recall.

I was driving on a residential street in washington, d.c. In my 2003 hummer h2 when I noticed after a briefly trying to brake for a pedestrian that my brake pedal was not as tight as usual. I continued to drive believing since no warning lights then there's no issue. I came to another stop and realized their is something wrong my brake pedal was very loose and almost to the floor with minimal stopping ability lucky I was now at my home I coasted to my home by now the brakes have blown completely I had to use the emergency brake to stop the truck. Thank god I survived. Upon inspection of my rear brake hoses it seems the left blew completely causing the serious issue. The warning light never came on. If I was going at a high rate of speed their would have been no question 2 or more fatalities.
