Calling 2007 H3 owners!

Got the engine light along with rough idle this morning! I only have 1950 miles on her and its a freakin 2007!! WTF! Taking her in to the dealer today and get a rental. This sucks big time! I am really disappointed already. Hopefully its an easy fix. This sheit shouldnt happen so soon. Sounds like an 06  head/valve problem. Who knows! Anyone have similiar expeirence?

HAVE NOT HAD ANY PROBLEMS YET..BUT ONLY HAVE 300 MILES ON IT. GOOD LUCK AND HOPE IT DOESN'T TAKE LONG FOR YOU TO GET IT BACK.

See my Check Engine (CE) post down below. I have an '07 (now with 24,000 miles on it) and yes, I need a head replacement (that is after the throttle-body replacement that i was told was the cause of these very same symptoms).
 

7398 on ours and no problems  (knocks on wood)

Mine has only 6K and the only problem I had with it was traction control was disabled (I got my H3 this way) - dealer replaced sensors and no other problems ever since.

2007 H3 with 13000 Km (8000 miles) and no issues at all.

I'll refrain from comment as I don't want to jinx my a$$

Let me add that my problem surfaced at about the 18,000 mile mark, so keep your eyes open for when you get to around that mileage. I first noticed the intermittent rough idle, then the CE light came on then it was off after a few additional starts, then same thing again. My scanner showed "multiple cylinder misfires" as did the dealer's Tech II.
 
Has anyone had a head problem after their's was replaced?

thx for the heads up
our 06 had 19k  when  the nasty head issue popped up
only took 2 days and we had ours back
and 2 days later we traded for the 07
kinda scary that some of the 07's are doing what the 06's did
maybe i should trade it in on a 08

Sorry to hear of the 07's getting this problem..I can only imagine that there still is a QC issue with the vender making these heads or engines for GM..Hang in there, I'm sure the problem will be fixed..unfortuantely it's at you inconvience

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 this AM 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.
