EXTERIOR LIGHTING

SUSPENSION:FRONT

i have a 2008 hummer h-3. on november 3rd 2009 while driving about 30 miles an hour on a sharp left curve, there was a loud clunk in the front end and the truck pulled hard to the right making the vehicle go down into the ditch. several week before this incident while in a parking lot making a sharp left turn( less than a mile per hour) there was a real loud clunk in the front passengers side, this happen twice including a week before the failure. when i checked under the front end i did not see anything. the vehicle was taken to the hummer dealer but they could not tell if anything failed. something failed! this causes me great concern because if it happened on a main highway and the vehicle went into traffic, that would not have been good. please help me find out what went wrong as i don't think hummer is going to help!

problem: rear passenger doors when driving in wet mud,slush freeze rear passenger doors shut in freezing weather... you can not get doors open from inside or out.... children or adults will be trapped inside rear passenger seat with really no way out... there is no rear cargo manual door release either... most adults could not get over seat front or rear seat to try and exit vehicle anyway.... this door freezing has happened to me (3) times when driving on wet slush or muddy roads in freezing weather......the rear doors take in these elements because of poor designed rear door seals... when i say frozen shut, i mean really frozen.... these elements also make it into the sides of the rear seats.... i will report this condition to gm hummer but i believe i'll only get a run around.... i feel this could be a death trap for children or anyone... thank you for your time.... if you can please do something about this issue.....

smell of burning plastic and the a/c stopped blowing. the a/c works on the lower speeds. burnt/melted plug on the a/c resistor plug. from what i have found online this is a very common problem with h3's at about 40-60k miles. why wont gm do a recall if this is a daily problem with h3 owners. how many h3's have caught fire from this ? it was over a 110 degrees when mine went out. what if i had young child or an elderly person in the vehicle at that temp ?

i looked on the internet to find out why my heater blower was not working and there were lots of complaints about the wiring harness and resistor burning out. i checked mine and sure enough mine was burnt on the wiring harness all the way through the plastic. gm needs to figure out why it would cause it to malfunction like that cause it could cause a fire.

i was driving in very thick fog which was a white out. i was going through a turn and was lost in the fog quickly and i ended up off the side of the road struck a speed limit sign and a utility pole on my drivers side door because i seen it at the last moment and tried to avoid hitting it. but at the point of impact my driver side airbag never deployed at all causing me to suffer numerous broken ribs and loss of work for over 2 months time. i wasn't driving fast at all actually was going under the allotted speed limit. but due to my injuries the had to extracate me from the vehicle causing it to be a total loss because they had to cut it apart running my vehicle completely. i was not happy about this at all.

the radiator had a crack in it when we bought the hh3,in 6-2011 which was replaced with a new factory radiator. it is now march 0f 2013 and we have another crack in the radiator. we contacted" savvy" goodyear in long beach ,new york who replaced the first one and they said it is not covered. really does a radiator only last 2 years. they indicated that gmc would not cover the replacement. i see that this has happened to several vehicles shouldn't there be a recall?

radiator end tank ruptured releasing coolant on everything under the hood and getting on the windshield. research of this finds that there is a defect in the design of the factory radiator which gm refuses to take action on. had this happened at higher speeds, this could have been a much worse situation.

we practiced winching techniques with sno cty search and rescue. my vehicle was being winched up a hill. when we finished our practice, i notice the airbag warning light on the dash was illuminated. i took the vehicle to a gm dealership who sold hummers and had the vehicle diagnosed. they stated that the rollover sensor had indicated deployment. the vehicle did not roll, nor did the srs system deploy. they recommended replacement of the rollover sensor. i had them fully test the system to be certain that the $500.00 part would solve the problem. i had them replace the sensor with gm approved parts bought from the dealership. after the repair, the mechanic stated that he thought there was an electrical fault with the sensor - but had no way of testing the circuits; nor the willingness to try a part he fixed because it could deploy the system. the light is on again (the repair was completed june 11, 2013). i took the vehicle back to the dealership, where they pulled the entire dash apart and tested all the circuits. they did not find a definite cause. they recommended that we use dielectric grease on the connections. they indicated that if that did not solve the problem, the next "repair" would be replace the airbag itself (roughly $800.00). this is where i am at today - the light is illuminated again; gm has basically washed their hands of the vehicle (there is no warranty so all of this is coming out of my pocket); and they want to "try" to replace the airbag. i'm now concerned that the rollover sensor was not at fault; rather, there is an electrical problem with the srs system. i think the dealership has done the best they can - but without gm's participation in the solution; i think i will be continually throwing parts and still not finding the problem. gm can test these parts; they have the schematics; charts; and ip to allow them to find the issue.

i have the same issue as hundreds of others with gm's faulty blower motor resistor. the blower motor resistor and wiring harness have failed 2 times now. melting to each other. luckily no fire, yet. these are expensive vehicles, and gm should own up to the design flaw and issue a recall, and or offer a repair kit that truly fixes the flaw that owners can install as the location is fairly easy to get to and work on it. the purchasers of these vehicles should not have to put up with this quality flaw, and risk themselves, family and friends. gm - do the right thing and avoid major lawsuits.

as many have explained before, my blower motor all of a sudden went out i started to read online what it might be and found that everyone complained of resistor harness wire burning out or the plastic melting. and just as everyone said i pulled out the harness and it was burn completely out. gm this really needs to be addressed, how many people need complain, or something possibly happen to someone before your company takes action, with all the recalls going on with your company you would think you guys would learn.
