From owner reports, verbatim
The pass lock in this vehicle is faulty. On numerous occasions, it has left me unable to start the vehicle, but if you wait 10 minutes each time, it will start again, but it happens all the time. I've seen numerous complaints online and GM needs to do something about it.
The last dealership I went to they advised to come th the dealership but when I got there nobody wasn’t trying to work there instead the said that it was going to be hard to work on it cause nobody work on those cars anymore and then they said they were going to order the part but never call me back for it. Call them but gave me the runaround basically.

Engine was replaced at 163,000 miles now at 168,000 miles the frame is rusted beyond repair and is about to give at any moment nothing really left near rear axels. This could have definitely caused a horrible accident to myself or others having a big car just give way and collapse. Took it to mechanic who warned me first then next day took it to body shop that said nothing could be done. Basically both said get rid of it for parts as fast as you can and don’t look back. After the body shop guy actually showed me the rusted out areas i was scared to even drive it like the 10miles back to my house. It sucks after spending all that money on an engine and now having this issue and now having to buy a new car.

The contact owns a 2008 Hummer H3. The contact stated that while his son was driving 35 MPH, there was a loud metal rattling sound while attempting to turn left or right.

The vehicle was taken to an independent mechanic, where it was diagnosed, and it was determined that the leaf springs needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 67,000.
I was not involved in an incident. The rear frame of this vehicle has rusted 90% away. if it were driven any further the rear axel will fall off. I was towing a boat and it and the axel and rear bumper could have flown off the vehicle. I had no idea the extent of damage. I've owned the vehicle for 11 years. I've read that other Hummer h3 owners have had the axel fall off. Please let other Hummer h3 owners know how severe this can be. Every northern tier state vehicle 2008 and older with 146,400 miles can not have this dangerous of a situation. I've attached a 2011 Buick lacrosse recall of a friend. This truly is a hazard. I had no idea how bad it is.

The fuel level sensor stopped working now it say I’m on E These go out on these cars And are on the recall list, but not on my vehicle yet
THE ANTILOCK SAFETY IS PREVENTING ME FROM STARTING MY VEHICLE. WHEN IT DOES START, AND I GO TO AN INTERSECTION TO TURN THE TRUCK WILL THEN STALL OUT. IT CAN CAUSE A WRECK. IT IS A HUGE SAFETY ISSUE, TIME CONSUMING, AND MONEY CONSUMING WHEN I HAVE TO WAIT 10 MINUTES TO TRY TO START MY TRUCK, OR IT DOESN'T START, I HAVE TO REPLACE IT FOR $450+ WHICH I DON'T HAVE TO REPLACE THE IGNITION SWITCH AND IT'S DANGEROUS BECAUSE IF IT DOES LET IT START I HAVE TO BE CAREFUL BECAUSE IT WILL STALL OUT ON ANY GIVEN SECOND CAUSING A CATASTROPHE!!! THERE ARE MULTIPLE PEOPLE WITH THE SAME ISSUES ON THEIR VEHICLES. GM SHOULD BE RESPONSIBLE TO DO A RECALL AND FIX THIS PROBLEM.

TAKATA RECALL. I WAS DRIVING BETWEEN 10-15 MPH ON A SIDE ROAD APPROACHING A STOP SIGN TO GET ONTO THE MAIN HIGHWAY AND THE SIDE AIRBAGS ON BOTH SIDES DEPLOYED ON THEIR OWN. NOTHING HIT THE VEHICLE TO CAUSE THEM TO RELEASE. IT LOCKED UP MY FRONT SEAT BELTS ALSO. I CUT THE AIRBAGS OUT TO BE ABLE TO SEE TO DRIVE HOME, AND WAS ABLE TO PULL THE DRIVER'S SEAT BELT AROUND ME ENOUGH TO MAKE IT HOME. I CALLED MY INSURANCE COMPANY AND THEN CALLED THE LOCAL HUMMER DEALER TO LEAVE A MESSAGE FOR THEM TO RETURN MY CALL. MY INSURANCE COMPANY TOLD ME IT WOULD BE A DEALER ISSUE, AND NOTHING THEY WOULD COVER, BUT ADVISED ME TO GO TO MY LOCAL INSURANCE AGENT AND TALK WITH THEM ON MONDAY. THIS IS SATURDAY, JULY 16, 2016 AND NEITHER THE INSURANCE COMPANY OR THE SERVICE DEPARTMENT OF THE DEALERSHIP IS OPEN UNTIL MONDAY. I AM NOT SURE WHAT HAPPENED, BUT BELIEVE THAT THERE IT MAY BE CONNECTED TO FAULTY SENSORS ON THE SIDE AIRBAGS.
