Open the full vehicle complaint log (all categories)Was driving this vehicle about 45 mph and began to shake violently. Was able to get it slowed down and back under control. Happened two more times on my drive home and took it to an auto repair shop today and found the frame is broken on both sides in front of rear leaf springs.
I was driving the vehicle at a normal rate of speed and stopped at a traffic light getting ready to change. I applied the brakes and when doing so, I heard some horrible noises and felt certain that parts had fallen out of the car. I knew something was immediately seriously wrong. I put the car in park (but it was effort and a grinding noise to put it in park) and stepped out to look under the car. No parts were on the ground, but something was leaking out of the bottom of the car. I got back in and put the car in drive to move it from the roadway knowing I was going to need assistance to tow it somewhere. It grinded trying to put it in any gear and only "revved" the engine when I tried to apply gas to drive it. There was absolutely no warning. The tow driver immediately noticed the drive shaft was disconnected and that was the leaking and thus going nowhere. My mechanic said that both leaf springs snapped off and that caused the drive shaft to sever, hitting the gas tank (or strap) and some other things. My concern is that there is a recall on leaf springs for every year Hummer H3 except mine as well as 1995-2015 Chevrolet, GMC, and Hummer leaf springs. I'm having a very difficult time with how both of mine snapped with no warning tearing all of these components out and it is not involved in the recall. It is the same parts on all of these. Also, my vehicle has spent the majority of its life garaged, never driven in the snow or rain, as I have babied this car. I have a car wash membership too and constantly keep this car meticulous. Hummer said that enough people need to complain, but I would not even have thought to complain had BOTH not snapped off simultaneously finding the recall for all other years while researching the cost. Had only 1 broke, I wouldn't have given it any thought. And Hummer said that they wouldn't even talk to me unless my car was at a GM dealership. This should be included in the recall. This is not pure coincidence. They need to fix it.
Complete rust through of frame of my 2006 HUMMER H3.
Frame rot all the way thru from front to back. I am able to poke holes in spots all around it.
I PUT IN 4HIGH LOCK FOR SNOW. I LATER PUT TRUCK IN 4 HIGH. IT FEELS AS IF IT'S STUCK IN 4HIGH LICK. I TOOK IT TO REPAIR SHOPS AND WAS TOLD IT'S THE 'PLASTIC FORK' ON THE TRANSFER CASE AND THIS IS A FAULTY PROBLEM. THE FOR WAS LATER CHANGED TO A METAL KNE BECAUSE OF THIS PROBLEM. IT SHOULD HAVE BEEN METAL IN THE FIRST PLACE. THIS IS AN EXPENSIVE COST AND I AM IN GREAT HOPES THAT THE MANUFACTURERS WILL HONOR THIS.
