While I may be proven wrong in time, I doubt the '07's have "a" head problem. Sure, a few may come along that have head issues, but I don't think we'll see a bad run again like the '06 models had. It is bad news in any event, but no sense getting all worked up or crying wolf about it. Obviously we will want members who have similar problems speaking up, so we can find out for sure!

 

Yes, I agree...I really think feces occurs with any machine and the few with this problem in the 07 is probably a coincidence..

 

Bad fuel injector, I was told by tech today. He ordered me a new one. Getting fixed on Monday. Got a Pontiac Grand Prix for rental-POS! Hopefully no damaged was done? He said no of course?

 

Well that's good to hear..I mean that it wasn't the head after all..Don't worry, a bad injector ain't gonna hurt a thing...It's just an aerosol nozzle that squirts fuel..and from some experience, I'd say it wasn't squirting all the times it should...sorta like shooting blanks....anyways, an easy fix.

 

i can relate to that shooting blanks thing . . . . did they find staples in the line to the injector? painful little bastards, in more ways than one . . . . .[:@]

 

Yeah , not too bad. Cant wait to get back in the saddle! I miss her!

 

Started my 2007 H3 thisAM and it started sputtering with the check engine light on solid. Only 9,000 miles and has been babied/not run hard or taken off road. It was running fine with no problems prior. Took to dealer this AM, bad head. 3rd repair so far (back seat latch not connected from factory, CD player malfunction, and now heads). NOT GOOD!!!!!!!!!

 

2007 Hummer H3 with 14500 miles purchased Feb. 07. It was manufactured 12/06. My engine light came on this week. I hit the onstar button. Got the question is blinking or solid. Told her it was solid. They told me it was an engine misfire & to proceed cautiously to the dealer. I went the next morning & the cylinder head was cracked. They told me it was safe to drive & they had to order the parts. They have to replace the cylinder head, 2 valves, & one gasket kit. I have never driven it hard nor taken it off road. I hope this is the only problem I have but I do have four other cylinders that I am now worried about. I do notice a loss in power & my mpg has dropped from 16 to 15.

 

Touch wood..... I've got 15,500 miles and mine is still running great. I've don't long road trips, tons of local road driving and some off roading as well. Mine is an early 07, purchased in Nov. 06.

 

The head is for all 5 cylinders, one piece. No problems at 10.5K.
