GM passlock system very randomly engages or is trigger without warning when simply turning the key in the ignition to start the car. However, the attempt to start the vehicle is not successfuly which causes the inability to power the vehilce for 10 minutes. There are numerous Hummer H3 owners with the same issue. The GM dealers are no help in resolving the problem. In fact I feel as if I'm making it up. I've tried 3 GM dealers now between Louisiana and Texas. The only thing are expensive guess at the problems the dealers state they can "try" to resolve their very own made GM system. I believe it's an obvious and known issue, because it seems GM made changes to the GM passlock system in the more recent years. I just hope if a dangerous situation ever occurs that my vehicle will start if I need to depend on it. Please check the other list of unhappy H3 customers at the web address(ES): www.hummerforums.com/forum/Hummer-H3-17/how-turn-off-GM-passlock-anti-theft-system-Hummer-H3-28665/ www.carcomplaints.com/Hummer/H3/2006/electrical/passlock_light_on_preventing_engine_to_start.shtml just because the vehicle is no longer in circulation, it doesn't mean we don't expect knowledgeable service or purchasing a new vehicle. Please help us. This is the most inconvenient issue and most annoying and potentially dangerous. Thank you when: And the vehicle is just parked at my home. I walk in my garage, turn the ignition, and nothing happens... ugh!!! security light may or may not flash. But that's my cue to go back into the house and sit for 10 minutes before I can leave my home. And this happens everywhere I go: Grocery store, parking in the cold, to the mall, to the movies, and the list goes on. It often occurs one right after the other depending on how many different locations I need to travel. Therefore I have to tack on extra 10mins to each location.

I rec'd a safety recall notice 8/15 for 2009 H3 recall# 15042 or 15V421 (2 different # in letter) from Hummer. The connector module that controls blower motor speed may overheat." If this condition occurs, there is the risk that the heat generated could melt the plastic surrounding the connector module, which increases the risk of a fire" I called dealer-and told GM has no "fix" for this issues (I call every few weeks) I called GM direct that said they don't have the parts yet to fix it. I was advised to drive around with a fire extinguisher in vehicle and not use the fan and leave the car if I smell smoke. Nothing has happened yet and I am not using fan but I would like this condition fixed before a fire occurs. It is very unsettling to drive this way. Hummer/GM

As in the other reports, my vehicle had same electrical short and fire under passenger glove box area. Here is the technician repair notes which completely verify there is an engineering problem with A/C and heater blower motor electrical configuration: Verified customer concern, opened and removed glove box, removed blower motor resister (2fastners) from HVAC box, inspected resistor, attempted to unplug resistor, connectors stuck together, forced connectors apart, found they were melted together due to short in HVAC system. Installed new harness: 25949869 installed new resistor: 10397098 blower motor HVAC system now operable; unknown reason for short.
