About the VIN, I checked mine and I fall in the group but I did some investigating and only the last 6 digits are the serial number.
The code: 68287591
The first digit (6) means its a 2006 and the second digit (8) means assembly plant #8 which is the Shreveport, LA plant.
so the S/N's affected is 287591 but the first vehicle off the line is S/N 100001 so 187,591 H3's could possibly be effected.

actually I'm guessing you don't read the forum all that much, because as stated by a hummer tech there has been a PI issued from GM stating that all h3's with the last 8 of the vin before 68287591 could be affected....still think GM would put out such a PI for something that is "rare"? Now a PI from GM with a specific VIN number run IS EVIDENCE that this has/will effect many h3's on the road today....check your VIN...Bet your one of the ones that may run into problems.

GM absolutely would put out an order; to go on the record with monitoring and corrective action as a defense against potential class action suits for problems not acted on. If the problem had a significant occurance probability, owners of all potentially affected vehicles would be notified to take it to the dealer for inspection, if not to schedule head replacement. After the BMW paint case, car makers know better than to play games on warranty issues. Too many lawyers ready to pounce. Trolling for victims to enroll in class actions is also pretty common on auto forums. Not even GM is that dumb (I hope). I don't know what "the last 8 of the VIN" means; eight digits covers 100 million VINs.

Don't get me wrong, I niether defending GM or downplaying the problem for those affected. If I do have cylinder head problems I will be pissed. But you and others seem to be making a case that GM is doing something devious or stonewalling, and I see little basis for that.

I have never said anything to the effect that I feel GM is doing something devious...I think you have me confused with someone else. I actually posted the exact opposite thing in other threads, I feel GM found their error and has made the proper corrections in making harder valve guide castings. Some have made the whole gm conspiracy theory...I am not one of them.

does anyone know how many of I5 vortec engines has been produced 200,000. 300,000.. more??. since 2004. They are in use in the COLORADO and in the CANYON and... in the H3

I don't believe for a second that there is a flaw in the design of this engine.

the problem might have an external reason... let's try to find out the common factor linking together all the forum members having the problem.

HUH????? there IS a flaw...gm knows there was a bad batch of heads and are now casting the heads differently. I guess you can believe what you like, but the bad heads that where put on some of the h3's is a FACT that gm is correcting.

If I may internationally mediate here

These engines are in fact the same used in the Colorado and Canyon..very true..But as all car manufactures do, they sub out certain parts of the engine to be made out of house and I'm sure to the lowest bidder..The Heads are not a pure common componet on any engine and the H3 has had some (minor) design spec changes to accomodate the H3...The supplier of these heads is where the fault lies..But the basic BLOCK is still the same.
