Recently my 2009 Hummer H3, has been acting strange. While driving down the road, warning lights will flash, will beep, (traction control, ABS, service 4WD, change oil, service tpm), all the while all things electrical stops working such as headlights, brake lights, blower fan, heated seat, turn signals, and all this while driving down the road at normal speed. It started doing this as the weather got colder but this H3 is well maintained and is garage kept and I only use it to drive to and from work. It is now a safety hazard and with these issues will not be able to trade it in. I have no idea where to start in order to fix it. After finally driving for 30 min or so sometimes it will finally quit messing up and act normal.

The truck will lock the ignition out for 10 minutes. You are unable to start the truck. Now having that happen in an undesirable parking area or out in the winter old, is not safe. Has been happening at random times for the last 4 years or so.

Can you please help"?????"

Needed recall for Hummer H3. "reduced power/service stab system/traction" notification that appears without warning, and immediately drops the engine to almost no ability to accelerate. This began happening in local traffic, then on the interstate at high rates of speed. GM has been notified of this issue, even after numerous attempts to repair this very dangerous malfunction without success, they are unwilling to address it with a recall. The most dangerous of the numerous times this happened was on 4/27/17. I had just left moses GM of charleston, wv after they had repaired the vehicle for this issue. I drove approximately 5 miles on interstate 64 before losing power, and almost being struck by a vehicle on the South charleston bridge. The dealership towed me back to the service center where the vehicle was once again unsuccessfully repaired. It seems that this is an issue with GM vehicles around the same time period, and not just the Hummer line. Any help would be greatly appreciated.

The contact owns a 2009 Hummer H3. While attempting to start the vehicle, it failed to start initially. The vehicle felt as if it had a delayed start. The vehicle was taken to the dealer where it was diagnosed that the battery failed and would need to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that the vehicle was taken back to the dealer on several occasions where it was repeatedly diagnosed that the battery was the reason for the failure. The contact stated that the battery was changed a total of three times in four years, but the failure continued. The dealer mentioned a manufacturer's recall for the wiring for the contact's year, make, and model, but insisted that there were no other recalls. The manufacturer was notified of the failure. The NHTSA campaign number was unknown. The failure mileage was 2,000.

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.

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

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 GM Hummer with 39000 miles has an issue with the ignition/ disabling system. The vehicle cranks some time and some times it doesn't displaying the locked security symbol on the dash. It has come on while driving and I'm concerned it will shut the vehicle off. I'm absolutely concerned for me and my families safety. I have quit driving the vehicle as much as possible.

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.
