 Purchased a 2006 hummer h3 from the seller in this complaint. i paid exactly $23,250 all cash for this vehicle. he actually drove the vehicle to new jersey from mass. to my residence. the vehicle appeared to be in excellent condition, as it only had 14k miles when i bought it only 3-month's ago. one would hardly think of hidden issues at that mileage. in any event, i have had repairs to the rear and front differential, as it had a leak and the front end was out of alignment. the most disturbing thing was this seller lied to me and misrepresented the true or actual condition of the vehicle. unfortunately which would surface after he left with my $23,250 in cash! i would e-mail the seller and told him he misrepresented himself and the condition of the vehicle and how he apparently abused it. more importantly, i discovered excessive rust underneath this vehicle. because these conditions were not divulged to me by mr. johnson, i am having a hard time selling the vehicle that practically cleaned out all of my savings. he claimed this truck was garaged kept and that he did no off road riding. this apparently is totally untrue, as the car would not have as much rust as it is loaded with for a 2006! so, can you tell me what recourse, i may have as a the buyer, besides hiring a private attorney who i can't afford, as i am on permanent disability. there must i something my i can pursue under any state or federal consumer laws, especially, since the vehicle is still under warranty by general motors.. i should also add that i am having difficulty with a local hummer dealer royal hummer in florham park, who seemed reluctant to address the many issues i am having with this hummer! i would also appreciate if you can forward this complaint to general motors corporation, in michigan, as they should know i am having difficulty with dealers wanting to honor,as they should, any warranty work! i am prepared to file every complaint i could to get restitution for this apparent. *tr

 I have a 2006 hummer h3 with app. 79,000 miles on it.. i was driving to work on the highway and halfway there, i started to get a really bad vibration and loud humming noise coming from the driveline. it starts at about 40 mph and comes and goes every few seconds. its worse when i hit the gas pedal.. the universal joints have already been replaced due to cracked universal joints for some odd reason.. the top end of the engine had just been rebuilt 2 weeks ago as well due to sticking exhaust valves. this truck is babied and has never been off- road. mainly highway miles only.. i just had it aligned. all the fluid levels are correct. all the driveshafts are tight and nothing seems to be loose.. no modifications have bben done to it.. very unsafe to drive because something could lock up and make you lose control of vehichle.. this will be the 6th time i've had it in the shop for problems...

 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
