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.

Vehicle will not crank. After 10-12 minute wait vehicle cranks. According to symbol this is an anti-theft lockdown. But it happens repeatedly for no reason. Has happened 5 times in 6 days. My concern is this could happen during an emergency or in a dangerous place for a woman alone (dark deserted parking lot for instance). For this reason I am very conscious of where I park, but the 1st time it happened, with no warning, was terrifying. From what I have read even replacing the ignition does not solve the issue permanently, the same thing begins to happen again.

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.

The security lock system on my Hummer H3 intermittently flashes during start causing the vehicle to not crank. Normally I have to wait 10 to 20 minutes for the system to reset itself and she starts right up, but today it's been 8 hours. Finally I had to call for a tow to the GM dealership. We got lucky today. At 10am my wife thought she was going into labor, we get to the truck and no start. Just a flashing security lock symbol flashing at me. Ended up using her car. This is definitely a safety concern, what if her water had broke or my son was needing medical attention. I know GM knows of this defect because I have read thousands of complaints about this exact problem online. They will not fix it unless made to.

The anti-theft system activates on its own. Several times in the past two months when I go to start my vehicle it will not start because it thinks its being stolen. I have purchased a new key and also switched key fobs. I can park the car in the garage in the morning and at 5pm when leaving work go to start it and nothing. All the dash lights come on but, it will not start.

Upper rail rubbed against the plastic tank on the radiator, creating a crease that fractured, spraying radiator fluid all over the engine compartment. Radiator had to be replaced. Tech advised that the design of the vehicle was faulty because the rail was installed too close to the radiator. He shimmed it to prevent it from happening it again.
