My Hummer has been in the shop 3 times, for the same problem. I am so ready to blow this car up. I drove these vehicle in the Marine Corps of coarse its a Hum V, and built differently I would hope so but if our troops have to rely on this vehicle I would rather go with the Jeep a better built vehicle by far. This thing has been nothing but trouble from the beginning. I am ready to drop it from the highest mountain I can find. All its been good for is cleaning out my bank account. Its the worst built vehicle I have ever owned. GM should step up to the bat and recall everyone of them.

The vehicle engine light remains "ON" and there is a small chattering noise coming from the engine. It's a bit more noticeable when the engine is started and then it quiet down a bit. Also I guess during certain conditions it spits out a big cloud of white smoke during start-up but not every time.

Car running rough due engine problems. Very inconvenient due to not being able to use my vehicle until repair work is done. Parts have been ordered. Now have to wait for them to come in. Dealership is approximately an hour away from my home, and I will have to leave my vehicle for several days.

H3 3.5L 5 cyl
I am so irritated I can't even begin to form intelligible sentences. The check engine light came on, attempted to call Onstar twice for an on demand diagnostic but the system was down. Drove straight to a local dealer explained the issue and was told to try a non locking gas cap first to see if this corrected the issue with the check engine light. If not come back and they would schedule an appointment to look at my vehicle. Changed the cap. No resolution, light still on engine still running rough. Took to another dealer and dropped it off. A week later and 2981.92 in repairs and labor I now have new heads and valves. was told this was a known problem with the 2006 5 cylinder and that GM made changes in 2007. No recalls no recourse no warranty left. I have followed all scheduled maintenance on my vehicle and it only has 69,475 miles on it! This not the only problem I've experienced with this vehicle since it's purchase in 2006 (that's for another complaint). I'm gonna talk to a lemon lawyer!
