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.

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.

The contact owns a 2006 Hummer H3. While the contact's husband was driving approximately 10 mph, another vehicle suddenly pulled out in front of him. In order to avoid hitting the vehicle, the driver immediately slammed on the brake pedal and the leaf springs suddenly fractured. The vehicle's "U" bolts, shackle bolts, and rear shackles fractured. The failure caused the drive shaft to detach from the transfer case and the rear axle to lay against the rear mud flaps. The vehicle was towed to the dragon auto body shop where all damaged parts were repaired. The contact informed an unknown Hummer dealer who stated that there were no recalls on the vehicle. The manufacturer was made aware of the failure and provided case number: 8/3115342180. The approximate failure mileage was 106,520. Updated 11/01/17

Catastrophic failure of leafspring/rear suspension. Turning out onto road and heard a loud snap, steering went crazy, almost lost control of car. Saw similar incidents happening all over the web. Some ending in the truck flipping end over end. See common thread...bad weld in leaf spring and it snaps randomly over time at weld. Noticed someone on forums also complained with this NHTSA tracking number (10838131). Please look into this before someone gets killed!

On March 20, 2016 we hear a very loud bang in the rear of the Hummer.. rear main leaf spring broke off. We also have the loud bang when you put the vehicle in drive. Both are being investigated by GM engineers @john.criuitt@GM.com. This vehicle should have never been sold by the dealer auto serv of tilton, nh. They will not make good on this vehicle. The vehicle at the time was literally going 15 miles per hour. Can you imagine if we were on the highway!! we have the old leaf springs home with us for proof.

I recently starting hearing a clunk or rattle in the front suspension. I took it to one shop who suggested I replace the shocks so I did. After I left the shop, I noticed the exact same issue was still there so I took it to another shop. They stated that I needed to replace the upper control arm bushing so I did. Unfortunately, neither fix solved the issue so I took it to yet another shop, ken graff in riverdale, Utah who informed me today that the issue is a front lower control arm, that is documented on the GM website. The document number is 2367563 dated 11/10/2009. The engineers knew that this was an issue but their conclusion was that the condition was caused by an external impact event that exceeded the limits of the frame design, which is a line of bs. I have never taken my Hummer 3 off road at any time and it does not even have a scratch on the paint job and it now has 92,000 miles on it. It is common sense to just provide the bushings to the customers instead of making a customer pay out the A-- because of a lack of common sense. I did contact GM who informed me that they have concluded it was caused by exceeded the limits of the frame design. A few things here I find hard to believe from the engineers, that they recommended that the frame needed to be replaced and that it was caused by a external impact which I find strange concerning they were pushing this as a off-road vehicle. If they knew about this issue why did they not recommend a recall instead of blaming the customer? they did not recommend to GM to create just the bushings instead of replacing the whole frame ( $9000 per ken graff) my conclusion is they knew of the issue and were covering their own ass, if I were to place just the bushings and if they were available my cost would be less then $500, I can accept that but exceeded the limits of the frame design hell no.

Was driving 40 mph on a 2-lane northbound highway. Weather conditions were clear and sunny. A car pulled onto the highway and instead of pulling into the right lane, it pulled into my left lane. I had to press the brakes a harder than normal. At that point both rear leaf springs failed and blew apart, damaging the drive shaft and pulling the drive shaft from the transfer case. The rear axle was pushed to the very back of the vehicle, making it un-drivable. There was also some other underside damage, such as the emergency parking brake line, seals, gaskets, etc. I filed an insurance claim, however they determined the issue was due to a "mechanical failure of the General Motors vehicle." I have full coverage and none of this was covered under either collision (I was able to avoid hitting anything) or comprehensive. Repairs for all this are $4200 which are being repaired by a GM-certified mechanic at a GM dealership. I am now out $4200 and have no recourse with GM. I am the sole owner of this vehicle and have owned it since July 2005. I have maintained it in accordance with GM recommendations over the years and it was in excellent condition prior to this incident....updated 08/14/14

(6-03-14) the right rear main leaf spring broke causing the rear tire to lock up and be at the most rearward position that it can be, almost rubbing the body. Then today, (7-27-14) the left rear spring done the same thing except the axle moved so far back that the driveshaft came out of the transfer case and I had to have a rollback haul it to a repair facillity.
