Vehicle will lock you from immedatly starting. Our concern is what is we got lost and happened to be in an unsafe area? What if a female (or anyone] needs to quickly get out of an area but cannot as vehicle won't start? What if a medical emergency? Etc, etc. Waiting 10 minutes then will start. This issue is off no fault of vehicle other and is common with multiole huimmer owners. Thank you for your assistance.

Every so often the passlock security system malfunctions and my hummer won't start. I have to wait 10 minutes before I can start the vehicle again. It fails without warning. Its been happening more and more often. There was only 55,000 miles on the vehicle when I noticed it starting to act up. I sliced my fingers open on a job and had to drive myself to the emergency room but my hummer wouldn't start because of the ignition security failure. I lost a lot of blood in my hand sitting waiting the 10 minutes. The doctor said I might lose the tips of my fingers because it took so long to get there. I'm sure other people had worse situations, but I seen hundreds of people with the same vehicle having the same issue. It a dangerous issue and should be recalled before a life is lost if it hasn't already.

At any given time the engine will not crank. I have to wait exactly 10 minutes, then it will start as if nothing was wrong. It happens hot or cold. It has been about 3 years now and starting to happen more and more often. Dealer can not find anything because the problem is to intermittent. I believe it is the security system, but that is just my thoughts.

Vehicle is parked and this issue happens wether or not the vehicle has be used, just after turning it off or when its been sitting overnight. When I turn the ignition/key the vehicle will not start each time it makes no indicating/common noise when trying to start it. The battery, alternator and starter check out and are fine. Other gm products have this recall however, this one does not.(?)

My 2009 hummer h3 on occasion will not start. It can happen any time, any where, under any weather conditions. When this happens the car radio, interior lights, etc. Are however still working. I then have to wait approx. 10 to 15 minutes, and the vehicle starts up like nothing happened.. From doing some on-line research I found out that many, many, hummer h3 owners from years 2002 to 2009 have this same disturbing issue. I had this problem from day one when I bought this vehicle. However now it is becoming more frequent.. This occurred three times in the last week. Some attribute this to a faulty security pass lock system. I feel this is widespread dangerous issue and there should be an immediate recall on all hummer h3's that have this problem.

Vehicle will not crank up due to faulty pass lock-security system. After 10 minutes, the system will reset and start. At the beginning, this was infrequent, however, as of late, this problem becomes very persistent, several times a week. Gm has recalled many other gm vehicles with faulty ignition in 2014 for gm vehicles made during the same years as my vehicle. Gm did not recall hummer and should have.
