Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The problem was unknown to me and probably would be to any vehicle owner that is not a mechanic. I was driving a death trap and didn't know how easily it could have been a serious problem. The driver side leaf spring bracket had completely broke apart from the frame on the upper drive side corner in an area that without getting underneath the vehicle with a flashlight and specifically looking for would be impossible to see. The only reason I know about it now is because I took it for an inspection and it failed due to this structural defect which the technician informed me was a very common issue with the 2007 H3 vehicles. He said that if I had been on a highway at 65/70 mph and this thing broke completely free the axle would swing out behind the vehicle on the drive side and cause an uncontrollable crash that could lead to severe injury and possibly death

I have the well known issue with the passkey security system. Nothing is wrong mechanically with the car but the security system will not allow the truck to start, therefore leaving me randomly leaving me stranded. Much has been documented on this issue, yet gm has never done a recall.

So the part that is a malfunction is the rear doors weren’t made with any child lock and of course one of my kids opened the door while i was driving on the highway.I have a 3 and 5 year old and it scared me so bad I had to hurry and pull the hummer over and park and just held my son. I couldn’t even drive after that because of how bad it traumatized me. My mom had to come get and take me and my kids home and drive my hummer back home. Even though we didn’t crash or one of my kids didn’t fall out.it’s still a very serious safety hazard. I reached out to gm to see what my options were and there response was how gm made child locks in 2007 and up and that’s not the truth because mine is a 2007 and it clearly doesn’t have child locks. Then they later proceeded to tell me I should just sell my vehicle. I was so upset because if one of my kids would have fallen out and something happened I would do everything in my power to make sure they were held accountable and file a lawsuit against them. Yes The vehicle is available to inspect. My kids safety was at risk and then me braking and pulling off the highway in panic mode could have caused an accident.it’s been reported to gm and also local dealers. There was no warning just when it happened scared me so bad because my kids are in my back seat. The photos I uploaded are of the transcribed voicemails and I’m willing to also submit the voicemails from gm as well.
