Went out to start h3, turned key, check engine light came on, the battery light came on and the anti-theft system light came on. Passlock/security system inside the steering column is bad. Car won't start. Is unsafe and will strand owner without warning by not starting. Goes into security mode. Was told to wait 10 min and try again. Can't turn it off at gas pump for fear of it locking me out and not starting. I had this happen to me 4 times in one day. So many complaints all over the internet and people trying to fix this issue. There is even a company selling a part to bypass this and the security system which again is another issue. Gm is clearly aware of this issue. This needs to be recalled. Stranding people can be very dangerous. If there is an emergency and the car won't start. All around bad business by gm for not issuing this recall. This has nothing to do with mileage which gm manager said on the phone. These h3's are know from this fresh off the dealership floor. People are being forced to take it to a dealership for repair and replacing the part when the labor costs more than the part. Seem like a monopoly for gm and its dealerships. I have seen anywhere from 1500-2000.00 to install and rectify this bad part at the gm dealerships.

Hummer will not start, engine turns over normally, but will not start. Wait exactly 10 minutes and it starts up fine. Can happen any time, at the gas station, first thing in the morning. Learned that if the security light on the dash blinks when the key is turned on, the vehicle will not start. If light stays on, the vehicle starts. Have watched for this at every start up, can now tell when the vehicle won't start. This is a major problem with gm vehicles with pass lock since the late 1990s, gm need to take responsibility for this problem now!!!!!!!!!!

I stopped at gas station for fuel. Vehicle would not start for approximately 10 minutes after fueling up. Then it started. Apparently this is a wide spread problem with the hummer, as I have read a number of incidents reported on line with same issue.

Sir/ma'am, I am writing to complain about the 2007 hummer h3 security system not allowing the vehicle to start under certain conditions. I maintain my vehicle to high standards and over the last 8 months have had issues starting my hummer. When the hummer does not start, you must wait 10-15 minutes to even attempt to restart. The vehicle will turn over, but no fuel is sent to the engine to start. If it doesn't start again, you must wait another 10-15 minutes. The latter has happened to me 5 or 6 times in just the last 2 months. There have been numerous complaints to gm about this exact issue, and has fallen on deaf ears. Many vehicle forum users complain of the exact issue as well, with zero assistance from gm as seen here: https://www.cargurus.com/cars/discussion-c8039_ds531571 I am concerned that if the sporadic security lockdown (passlock) occurs while driving, fuel is cut off from the running engine, speed/steering/braking will be minimized, and the possibility of a crash is increased exponentially. Please advise gm there needs to be a fix for this and ensure they comply! Thank you for your time. I believe my photos of the blower motor fan resistor being burnt helped get gm issue a recall, and I hope this will urge them to fix as well

Vehicle won't start. The passlock prevents the vehicle from starting. The car alarm will start while I'm outside the vehicle and then the vehicle won't start. I replaced the battery but the passlock still makes the alarm go off while its locked in the driveway.

I purchased this 2007 hummer h3 on june 2016 with 77,000 miles on it. On 11/13/2016 with 80,300+ miles , I experienced the first no start condition due to "passlock theft-deterrent system" indicator blinking when I tried to start the vehicle. I looked up the owners manual on page 100 and it indicated to wait 10 minutes before starting the vehicle again. The vehicle started after waiting for 10 minutes. The second no start condition with "passlock theft-deterrent system" indicator blinking again was on 12/05/2016 with 80,900+ miles and outside temperature was freezing point at that time and I have to wait 10 minutes inside the cold vehicle before I can start it again.

Repeat no start due to faulty security system. Had to go to emergency room and could not go due to faulty security or "pass lock" issue and this is apparently known. Why is there no recall, this is a safety issue!
