Add me to this long list of folks with H3 problems... my daughter and I were on our way back to Texas from a mission trip in Shiprock NM on Friday night, and got stranded for 5 hours in a remote area of New Mexico ~100 miles from Albuquerque in the middle of the night! Yesterday, after having it towed to an Albuquerque Chevrolet dealership, the initial diagnosis is a new engine is "probably" needed. However, they need to physically remove parts of the engine to fully diagnose and it will cost ~$700 for them to do the work next week (not enough time to complete on Saturday). Needless to say, I am now spending $700 to get the car transported to Dallas to allow my mechanic to diagnose and repair the car.
Symptoms appear similar to other reports of head problems found on the Hummer Forum and other websites. The H3 was losing power while going up hills, check engine light came on, started making noises and then finally died in a very remote area of New Mexico. Have had this car since new in 2006 and it has 134k miles. I cannot believe that the engine may have to be replaced at 134k miles!
Pending final diagnosis, would be interested in joining a lawsuit and can be reached at firstname.lastname@example.org.
I bought my 06 Hummer H3 1 year ago with 55k. About 2 months ago I got the rough idle and was told by a certified mechanic that #1 cylinder was bad. So I drove it home and parked it. After calling GM and getting nowhere, I decided to get a second opinion from another garage. On the drive there, guess what, the transmission goes. The vehicle has 73k and needs a new motor and transmission. Where's the class action lawsuit?
Also have an H3 2006. The engine light keeps coming on, and the mystery is to see if it is what everyone is discussing here. Has anyone started a class action against them? Also, with all the GM cars recalled lately, why isn't this going to be taken care of?
My family members have owned both the H-2 and H-3 Hummers.
Unless one drives off road a lot, I see no purpose whatsoever in the H-2. It has zero performance, horrible handling and 5-mile-per-gallon fuel economy.
As for the H-3, it was a gussied-up Chevy S-10 with ten grand tacked onto the price and half the fuel mileage. Those family members now drive far more sane large trucks (one Chevy Avalanche and one Ford F-150). GM made the right decision in dropping Hummer.
I have a 2006 H3. It has about 113,000 miles on it. It is starting to throw misfire error codes on #4 cylinder. I have a feeling it is a blown cylinder head. Please contact me if a class action lawsuit is started. Jpickard4@centurylink.net. Thanks!
Same problems here. Almost done paying off my 06 H3 and now the excitement is gone. My Hummer has been overheating and leaking coolant. I am waiting on a diagnostic, but it does sound like it is a problem with the gasket or the cooling system. Class action I agree. Please contact me as well thanks. email@example.com
Hello, I have recently purchased a 2006 H3 Hummer in June. I drove it off the lot and the check engine light came on after 25 miles. I took back to dealership after inspection; the head needs to be replaced. I'm currently fighting with the warranty company to repair it. They will not pay for repairs. If there is a class action suit, count me in. My e-mail is firstname.lastname@example.org thank you. If we all come together, we can get this issue taken care of.
