| The check engine light goes off and on intermittently. the vehicle was taken to a mechanic who performed a diagnostic that located the failure at the engine head cylinder. the vehicle was not repaired. the manufacturer was contacted and denied assistance with the repair because the vehicle warranty was expired. the mechanic stated it was due to an inferior soft metal used to manufacture the heads which caused a loss of combustion when the engine was idling. the blowback at idle was what was causing the engine light to illuminate. mechanic also stated this problem was a recurring problem in this 5cyl engine which is the same engine that is in the colorado pickups and is covered under a gm recall in the pickups but not the hummer. the mechanic stated that the issue will only get worst. please help as i was given a price to repair of approx. $4000 if i was going to pay for the repairs myself at the dealership. | |||

| I have two 2006 h3 hummers both with the 5 speed manual transmission. upon acceleration from a stopped position in first gear, depressing the clutch for the shift into 2nd gear the engine rpms revs to about 4000 and stays there. shifting into 2nd gear & releasing the clutch the rpms drop back down. accelerating to about 3000-3500 rpms, depressing the clutch, again the rpms climb to around 4000 and stays there. the same thing occurs during up shifts ... this has happened no less than 7 times on one h3 and 5 times on the other h3. the hummer dealer can find no stored codes, and can not duplicate this. gm has been notified, but nothing has been done to repair this problem because the dealer can not supply defect codes. this has been going on since august '06 with no end in sight. i have asked the ecu be either reflashed or replaced and was told it was too costly to just put parts in without any codes. i believe the software could be corrupted. and is not aware anything is wrong. thus there are no codes. *jb | |||
