What owners say
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.
Vehicle misfires frequently. Engine will nearly stall at idle due to misfires and shake the whole vehicle. Lack of power and efficiency. And juddering while accelerating. It is known to gm and many people have had to resort to cylinder head replacements costing hundreds at a minimum.
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.
Tl* the contact owns a 2007 hummer h3. While driving 45-50 MPH, the vehicle stalled without warning and all the electrical functions failed to operate. The contact was able to restart the vehicle after approximately three minutes. The vehicle was not taken to be diagnosed or repaired. The dealer and manufacturer were not contacted. The approximate failure mileage was 134,565.
The engine completely shut off while driving on a major highway. The steering wheel locked up and the car came to a stop. Luckily, each time this occurred, I was able to pull over to the shoulder. There were no error lights that came up on both occasions of this happening. The battery continue to die, even after being replaced three times in 6 months!
Tl* the contact owns a 2007 hummer h3. While driving 45 MPH, the vehicle stalled and the theft lock warning indicator illuminated. The vehicle was restarted. The vehicle was inspected by an independent mechanic and unknown fuses related to the electrical system were replaced, but the failure recurred. The manufacturer was notified of the failure. The failure mileage was 145,000.
Passlock anti-theft system is malfunctioning causing the dashboard lights and functions to shut down while driving the vehicle which, is very unsafe at night. It also prevents starting the vehicle randomly until you wait 10 minutes, after it resets.
My hummer stalls and dies at various times. This is dangerous and know one can seem to tell me why it dies while driving. I take great care of my truck and me I have metal shavings in oil. Dying in an intersection with children is dangerous. This needs to be addressed.
Passlock problem (gm security) causing the vehicle to stall at any speed with no power brakes or steering till you coast to the shoulder and try it again might go 1 mile might go 100 miles before it happens again, passlock light flashes when vehicle stalls, tons of people with the same problem on the internet, this has happened 100's of times till I took it to the only service mechanic shop on our island in alaska and it has sat there for a month no one can figure out the problem and no dealership has come through on the phone to help either
