My G5 GT 07 has this weird noise I dont know what it is... Its been there almost since I bought the car, I noticed it when my car had like 1200miles/2000km, and I havent been able to take it to the dealer yet.

No matter how long I drive the noise is there, it could be a 5minute or an hour drive.
Do you have the same noise on your G5s??
do you have any idea what could it be?

um that dont sound good lol it does that when its running?

 

[Caifan]

yah it does... But I only hear it when I stop at red lights..
Hard to tell where it comes from, but I think its from the rear

Last day I heard a G5 GT 06 with the same noise, but it wasnt that louder as mine, and the thicking was slower also


Basically its a thicking sound, and even after car is parked it takes like 5-10 minutes while the thicking decreases and finally stops

oooooh! thats the muffler are cars all do that. it it really loud on the g5 and cobalts then any other car nothing to worry about

 

[Caifan]

glad to hear that.. thx for the help

lol, that would make me nervous as hell

i've never heard that.
the only weird sound i have heard is sometimes after i start the car it sounds like someone is knocking on the back :lol:

 

[denlou]

I wouldn't accept that sound, it's pretty loud.

 

[th0ughtless]

is there a recall on that?

 

[Nighthawk243]

Sounds like my Grand Am did after it spun the #3 bearing...

I don't think that's the exhaust. Exhaust has a quieter popping sound. This sounds like a very slow fan hitting metal...

Ummm.. that's not normal, and whatever it is, will be under warranty.. better get it in to the dealer.

 

[06Pursuit]

thats the exhaust expanding, and yes it is freakishly loud

 

[th0ughtless]

I've heard that before with glass packs, but never that loud. lol

 

[njg5gt]

there's something wrong there.

 

[fusiongt]

thats the exhaust expanding, and yes it is freakishly loud

i thought it was the exhaust shrinking a little bit since it only happens after i shut my car off

 

[Smokey]

obviously a mixed opinion here, but in a case like that, you best be taking it in to be checked out. Could be something expanding sure, but it shouldn't keep doing that all the time. I wouldn't consider that part 'normal'. either way better safe than sorry, you don't it to result in you getting stranded somewhere if you have already noticed potentially something wrong.

 

[ajemery]

yea you might want to get that checked out...

 

[06pgt]

the dealer isn't gonna do anything for u most likely. Any car with stainless or aluminized exhaust make that sound. For some reason the G5's and cobalts are loudest. As soon as it heats up it makes that sound and until it cools, used to work in a dealer, hate the sound, gotta live with it

 

[Caifan]

I wish it didnt doit.. Im gonna take it to the dealer just to check...

Thanks all for your help
