Question about 2006 Hummer H3
Hi, my research on this issue has turned up phantom causes as sticking valves, ignition switch and seat movement.
On some Hummer, it turns out to be sticky valves in the head. GM replaced the head under warranty and the hummer haven't had any more trouble out of it. There is a recall for the 2006/2007 5 cylinder models and you should be able to have this taken care of at no cost.
Do you have a remote start? The H3 Bypass module has an issue with Remote Start. When this happens to you must wait 10 full minutes before trying to start it again (DONT USE REMOTE, USE THE KEY) the bypass module takes 10 minutes to get out of "theft mode" this is in your manual as well, I forgot what page. The only way to get this to full proof work is to get a shop to "OLD SCHOOL" wire around the bypass module.
