You will not get anything else. You could have asked for a better rental vehicle

Yah did that already. The dealer was shady and played it off telling me to talk to the rental place about it. All they had was a malibu so I got moved from an aveo to a malibu whoooopeeee! Its more of a customer satisfaction thing, basically I know under the contract i signed they did their part, they just did the minimum. And in the end their goal is customer satisfaction, and now they have an unsatisfied customer.

So are they gonna be cool and work with me a little or tell me to pound sand? Being my first new vehicle and first GM this will influence me on whether i want another GM or not. I'm trying to milk something out of them I dont deserve just for the heck of it but bottomline I've owned the car three months and they have had it for 1 of those months I deserve something besides a rental Malibu.

yah i know "the" noise is normal, but "mine" wasnt. Even if it was the paper work from the dealership said a grinding noise was present and that metal shavings were also present. Whether this was true or not ill never know but i got a new blower, it sounds a lot better, and now i am happy.

If my M62 failed I would say **** it and toss on a nice GT28/30R.

When parts breaks it's a great excuse to buy something better. I am also loving the STS rear turbo IDEA!

Yeah I like that STS rear turbo idea too. Probably won't work out well if you drive your car in the winter though.

my noise started the day i put the 2.8 pulley on.. its not bad and only sounds bad at idle. if you give it 100 rpms more than idle then it goes away.. if i felt the need to i would just up my idle using HP Tuners...

Mines sounds like that and I went to the dealership after reading this post and they are getting me a new supercharger as well. It's sounded like that since the day I bought it so I didn't think anything of it. oh well, I get a new supercharger for free!!

weird noise when i make a turn in a parking lot

So I am in the rental until they get the new blower in and installed.
Well everytime when i pull out of a parking spot and turn to leave it always make this loud noise when i turn the wheel. Sometimes it say low traction...but when i first got it for a couple of months it never did it..Do you think it just does because its the Winter time?

So, I'm back in the rental.......AGAIN
Sings *Back, in the rental again! Back in the Rental Again!* (It's the GM rip off of an Aerosmith song LOL.

I had bad bearings in my supercharger too. It cost me $350 to replace it because it was not warrantied since I have Intense Stage 4.

Mine does that noise when I turn left. It is annoying, any ideas?!

i think all the cobalts have a problem. my service person where i bought was a too dumb to be a service writer, but...
i can recreate that noise on demand.

slower than idle speed in first gear. drive forware doing a full wheel turn serpentine movement back and forth, i get a clunk from the right wheel area.

result, they say if it still drives well, nothing to worry about, "but sir, you have a modified suspension, I'm sure that is what would be causing it..."
i have a HR springs lowering kit in. i took it there for an alignment and to check the noise. the noise was there before the springs went in, and i had 800 kms on the car.
I am taking out the springs, and going to Devon, where they treat me like I'm not a mentally challenged adult. retarded, for all you ppl that say i cant say it.
