Default head replaced SECOND TIME

2006 Hummer H3,
Head replaced Apr. 4, 2007 at 13,000 miles for check engine light rough running.

Today Apr. 20, 2008, Took to dealer for check engine light and running rough.
They said cylinder 5 missing, needs new head. They had one in stock.
They gave me a rental and here I sit in disbelieve.

I do not remember seeing any threads on a second head.
I am going to do a search,
and I think I will check in the Alaska Lemon Law.

Dan

That Sucks

I had mine replaced at 12,000 miles. I was wondering if they had solved the problem... I guess not

Maybe in Alaska they didn't have an updated head in stock when they replaced it the first time?

Update on my second head replacement.
After 2 days they called and said the second head they put in was bad.
Have to get another one.
Two days later they called and said the timing chain tesioner bracket is cracked. Will be two more days.
They gave me a Tohoe for a rental.
I willing like this Tohoe.

Perhaps the ninnies should learn how to do a proper root cause analysis? I'm thinkin' it's NOT the heads that are the problems but something else? There's too many high mileage H3s like mine that are getting HAMMERED with no problems. It's not a head design issue in my opinion. I've got 53k (yeah, not much by some folks standards) on our '06 3.5 and believe me, half it's life is spent at full throttle (poor thing needs a little less ass or a little more grunt). No engine problems as of yet.

Neat thing about the little 3.5 is that driven properly, I can exceed 19mpg. But, driven hard, I only get a little over 15. It does indeed reward a patient foot!

Now, if I could just get a set of BFG ATs to last more than 25k!!!!...

2006 Lux 70k miles Manual Transmission high rpms buzzing around the high country daily. (Knock Wood) No engine or transmission issues.

Was in at MedVed today for an oil change and rotation and they were trying to get me into an Alpha....lease is almost up....big sigh.....
Solar Flare....they laughed when I said I didn't want the Chrome on the Alpha Lux and would put my black steps and grill guard on it.

My son, who now owns my '06 H3 with VIN xxxxxxx084 is still going strong in Colorado with 89,000 miles on it. No engine or drivetrain problems. I'm not sure if running Mobil 1 synthetic has anything to do with it, but it's the only oil the engine has ever seen. He is about to put his second set of brakes in, but living in the mountains is hard on brakes.

Any other symptoms? My 07 stalled twice on the way to work this morning, verry noticable "rough Idle", stalled when stoping at traffic lights. noticable fluttery sound while warming up, much louder on acceleration. 23k miles...however no engine light, ...yet. Any thoughts?

Give it a few more days.
You'll get the light.
Look at this way... you'll get 10yr/10,000 mile engine warrenty now.
Also new oil and coolant.
Hey I even got a free set of plyers I found under the hood.

Dan.
On my 3rd head. (wish my wife was as willing as GM)

Are you a technician? You obviously have never diagnosed or repaired one of these cylinder head problems. The problem is in the valve seats. The intake valves don't seal because the valve seats deteriorate. The updated heads have inserts in the seats. I've replaced probably 400 of these things and only had 1 of the updated heads come back needing another head. The reason yours hasn't had a problem is because you've driven it hard. We've never replaced one on a rental car because we all know how people drive a rental.

Wasn't this problem addressed and solved at the manufacturing plant in NY after it was identified in early builds and early 2006?
Most of the early problems with this have been shaken out, no?

Yea, but they sold a lot of them before the new heads came out. The new head didn't come out until like 7 months after the vehicle was released.
