PLEASE HELP, Rattles ugh !!!

[aclar266]

Hey Guys, first timer here. Got my H3 3 months ago, 2 weeks into it, rattle, Rattle rattle! I am SO frustrated. The major one is just over the back seat in the roof (i thought possibly a tack weld broke loose, but usually only does it in the cold mornings. No. 2 rattle is somewhere behind the glove box, again usually when cold. I have Rattle no. 3 behind the light switch/dial, and lastly, the suspension squeeks. OK, now I know I am a bit anal and want my truck tight and quiet since it is brand new, BUT, is this normal, anyone else experience this? I hate to take it to the dealer and have them rip down the head liner and dashboard, then for sure it wont be right. PLEASE HELP ! Tony

I wasn't trying to be a wise ass, honestly...

but at 61 years old i've owned enought vehicles to know rattles 99% of the time need the dealer...if you pull trim, or body parts or headliners and there are problems latter, and they can see someone other then the dealer took a peak it gives them the excuse to say

"HEY ! someone did unauthorized repairs and no more warrenty"

HUMMER is real good but in my opinion there are a few thing you just don't play with during the warrenty period...

For your rear rattle, try takin off the door that covers your jack and tightening the jack hold down knobs. I've had to do that a couple times in mine. As for the others, check what you can then take it in

Hate to say this I have owned 9 Hummers and ALL OF THEM RATTLED like crazy. This is a characteristic of the Hummer Brand. My Brand new $130k Hummer H1 squeaked and had rust on it!!!! All 4 of my H2s had horrible undercarrige corrosion and my H3s creaked as if they were 150 years old. Turn up your radio and the noises go away. If you take it to the dealer you risk plastic parts getting bent, broken or cracked. Push up on the headliner when you are driving and see if that stops it. If so than you need to drop the headliner and tape/fix what ever is making the noise.

Just my couple 2 cents :-)

i have the same problems with my 08. crazy rattles are coming from the back of mine. i think its the spare rattling. i brought it to the dealer and they said it was the exhaust. they put new parts on and i still have the loud rattling.

[aclar266]

hey man thanks for the input. yeah that "loose exhaust" excuse is lame. I do hear the spare mount rattle over serious bumps, but thats not it. I actually had my girl drive me around and sat in the back seat to listen. Its directly above the backrest of the back seat, and it rattles, loud. i thought at first it was some cables or wires hanging down but it just seems too loud. I am wondering if there is a cross member right there and the tack weld broke loose. But I have had dealers in the past tear down the headliners and dashboards, and things are just NEVER right after that.

I have the one behind the glove compartment when it is cool.

Haven't taken it in yet.

35K on mine before it started. Took it in to the dealer and everything was fine for one day, then it started back up just like before.

Funny thing, the loaner with 3K already had EXACTLY the same rattle!

A guy that I work with has the same rattle.

Seeing this many occurrences, you can't tell me that GM doesn't know about the problem and know what the solution is.

I just had the sunroof replaced on my wife's H3 last week due to broken plastic stop that was rattling. It lasted only about 3 miles after picking up from the dealer before the rattle came back. Took it back to dealer and they pulled the liner to find the new sunroof was already broken. They contacted GM who told them to look for broken tack welds. They found one that had broke loose and are in the process of welding it back up. This is the second '08 they have replaced the sunroof on but the first with the broken tack weld. This rattle was coming from right above the rear seats in the middle. The shop was locked up when I picked up the rental so I didn't get a chance to take a pic.

Just got the H3 back from the dealer. It took them three days to repair. They had to use some sort of epoxy on the crossmember and reworked the weld that had broken per guidelines they got from the factory (apparently some sort of service letter exist on this issue per the dealer?). Never made it over to see what exactly was being done so hopefully it will last. It held for the ride home (25 miles) so we will see.

on my 08 h2 sut, before i took ownership of it, the service dept installed double face tape inside the pockets of the door handles on all 4 doors and re-did the trim on the front windshield...they said they do that to all of them because they come back the next day with the same rattles if they didnt do that from the start.

on my 06 h2 suv, i had my wife drive me around on some pretty harsh roads so i could locate the rattles...that was the best thing i ever did because i ended up finding all of them that way and fixing them.

i know what you mean by being annoyed of all the rattles even though its a HUMMER.

[joedirt]

I have those same annoying rattles in the headliner. I took it to the dealer and they said that there was a modification that needed to be made on the sunroof per GM's notification. I drove it off the lot and didn't hear anything until I took it on the freeway at 70mph.... ugh!!!! Well I am definitely taking it back to them.

[RubHer Yellow Ducky]

still no rattles on both of my H-3's

I had a rattle in the right rear some where as well. Sounded like something hitting metal. Did it all the time coming to a stop and acceleration off the line. No noise at highway speed. Around town drove me nuts. After taking out all the right rear trim and riding around in the back it turned out a harness that plugs into the passenger side rear seat belt behind the C pillar trim was rubbing on the long bolts from the right rear door latch. Taped the harness, wrapped it in auto wire harness foam where it passes through the opening and them put sound deadening material over the harness. No more noise.
