H3

  • 200,000 miles
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.

The padlock system that the car has it prevents the car to start and leaves you stopped for 10 minutes. It's been doing it lately more in the morning or when the car hasn┐T been moved in awhile. The security icon in the dashboard blinks when the passlock security enables and that leaves the car without starting.

My H3 has been having issues with random warning lights appearing. Often multiple lights like engine, check transmission and traction. Each time I would take it to mechanic and would not find a problem anything in engine. Then the 4 wheel light drive would not illuminate. The most recent problem is much worst... while the car was not running the right turn signal came on by itself. I got in it to drive it to local mechanic and while driving it activated the brake and many warning lights were flashing as well. Very disturbing. I have owned this vehicle since 2006 now it has 125000 miles. I have kept a complete history of maintenance that includes oil changed every time between 3500-5000 miles

My 2006 H3 has sporadic issues with starting for a few years now. When I try to start it, it will crank fine but will not start. If I wait approximately 10 minutes & try again, it starts with no problems. During this issue, everything else works in the vehicle (radio, lights, etc..). I've had it checked by several mechanics & replaced lots of parts but didn't help this issue at all. I have read many complaints reference this same exact issue online & through NHTSA but nobody has had any positive responses. This is a major issue that should be taken care of by GM as a recall. I will be part of this class action lawsuit through these threads related to this Hummer H3 issue. Thank you & waiting to hear about this terrible GM issue.

I have owned this car for 10 years. Its always giving me problems. Especially the electrical and engine. I've gotten 3 notices in the mail for recalls and GM has ignored my request. At this time I am holding them responsible because my Hummer H3 is always in and out of the shop and dont feel like ive gotten the value I deserve on my purchase. Please give me call at [xxx]. imy name is [xxx]. even though there are no more Hummer dealerships and no one specializes in the care of this vehicle, I have taken complete care inside and outside of my investment and hope to get some type of leeway in this matter. Thank you. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My 2006 H3 (50K miles) has starting issues that have been getting more frequent since last year. When I try to start it, it will crank fine but will not start.

The fire department arrived, but the fire was already extinguished. The vehicle was towed to the dealer (lakeside Chevrolet Buick, 10215 w main rd, North East, pa 16428; (814) 746-4300) where it was diagnosed that the dashboard, windshield, wire harness, and carpets needed to be replaced. The vehicle was not repaired. The contact received notification of NHTSA campaign numbers: 15V421000 and 10V179000 (visibility, structure). The parts to do the repair were unavailable.

The vehicle will turn over, battery is fine, but the engine will not start, due to the on-board security system thinking that the vehicle is being stolen. This frequent problem has been reported to the nhtsb numerous times and to GM with no results. GM customer service claims that they have never heard of this problem, but if you google: 2006 hummer3 starting problems, you will see a long list of exactly the same complaints. This situation should warrant a recall and repair at GM's expense. The current remedy is to sit and wait 10 minutes until the security system resets and then the vehicle can be started. This condition occurs without warning and is not covered at all in the owners manual.

Truck will not start for no apparent reason. Key turns, sounds like it will start but does not. This has happened on several occasions and seems to be an ongoing problem for other Hummer owners too. I just had it towed once again to the mechanics shop. This is the 5th time within one year. Unable to leave my house during an emergency, child related.

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.

2006 Hummer H3 security lockout engages randomly. Have repeated occurrences of engine not engaging upon entrance to vehicle. Have to wait 10 minutes before ignition will work again. Problem occurs approximately 3 times a week. Researching online I have found multiple complaints of the same issue with the 2006 H3.

While the vehicle is stationary and upon entering the vehicle, the vehicle will randomly not permit you to start the vehicle. After searching online on several forums, I see that thousands upon thousands of people are having this same issue with Hummer models, not just the H3. It seems that the ignition is believing you are a burglar, and it locks you out for 10 minutes. After the 10 minutes have passed, you can start the car with no problem. The only way to get around this (per GM) is to replace the ignition, but since there are so many complaints of this I believe it should be a recall instead of consumers having to pay for this flaw.
