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.

The H3 will not start. Dash screen keeps showing the passlock activated and won't turn off. Computer thinks the H3 is being stolen. I have tried to reset and no luck. I had this problem about 4 weeks ago and changed the fuel pump. Then it happened again last week and now on 28 March 2020. Engine is turning over and electrical systems light up, but sounds like fuel is not getting into the fuel pump again. After doing some research, finding others having the same problem. Recommended procedure is to wait 10 min, still no luck. Waiting 15 min seemed to work before, but now it doesn't. how am I supposed to be safely in the vehicle, drive somewhere and then it stalls again" I am the original owner and haven't had this issue until it started 4 weeks ago. What if this happens while I am driving on the highway and fuel stops going to the pump" this could cause a multi-vehicle accident.

The contact owns a 2006 Hummer H3. When the vehicle was started, it shut off without warning. The vehicle was towed to an independent mechanic where it was diagnosed that the fuel relay and the fuel pump needed to be replaced. The vehicle was repaired, but the failure recurred. The contact called edwards Chevrolet Buick GMC Cadillac at 712-366-9400 (located at 3400 South expy, council bluffs, ia 51501) and was informed that there was no recall. The manufacturer was made aware of the failure and referred the contact to NHTSA. The vehicle was not repaired. The failure mileage was approximately 91,000.

I bought this H3 Hummer used and it ran good until last year. It would not start at different times but after you waited 10 minutes, it would start. We just paid $1300 to have the fuel pump replaced last week. Now it won't start again. I have seen many complaints on this and there should be a recall on this problem.

I've had it tested and it's the ignition switch that I'm taking about. Why is this not being recalled!!!!! someone's life can be taken away for something that keeps happening to these Hummer H3!!!!!

GM has a security system called passlock that over time seems to fail and trips a "failure" and flashes a key symbol on the dash and disables starting your vehicle until it resets 10 minutes later. This occurs to my wife almsot 50% of the time she tries to start her vehicle. So far GM has come forward with a fix yet I've seen posts on Hummer forumns from hundreds of owners. This has many safety concerns as well as just being a general annoyance: 1) in las vegas we routinely see tempatures over 110F. If the system trips and you have to wait 10 minutes in that heat it can be deadly 2) missing appontments or being late to work because you vehicle intentionally is disabling itself it unacceptable 3) groceries cold/frozen stuck in the heat for 10 minutes waiting for a reset get ruined 4) my wife when alone is stuck waiting outside the vehicle in the heat or locking herself inside waiting for the system to reset can leave her exposed to criminal types

The contact owns a 2006 Hummer H3. The contact stated that the seat belt warning light was illuminated for twelve months. The check engine and the evaporation system lights had also been illuminated since 2000. The vehicle was taken to the dealer who stated that the failure could be related to the evaporation system and gasoline cap but the dealer was unable to determine what caused the failure to occur. The manufacturer was not notified of the failure. The failure mileage was 38,000 and the current mileage was 79,000. The VIN was not available.
