Has anyone had this problem on a 2011 model? I am hearing a noise under the car that sounds like a little fuel dump with a metal noise too. I don't know how better to discribe it. I have taken it to the dealership and they can not duplicate the noise...like going to the doctor and you feel better in the waiting room...

is there a TSB on the valve covers baffle of a L99?

Onyx · 06-08-2012, 01:28 PM

The TSB# is 2756752

Of course they have to see it to believe it. I have a 2010 model built before #50,000. I only have 22.3K on it and will be printing out the TSB and placing it in the passenger seat when I drop it off. That noise is a whole lot worse on the outside. It sounds like a chevette!!! Argh!

Brandon,

Ken Dixon Chevrolet, Waldorf, Md was very professional and stated that it would take up to 7 business days to get the parts. They had it back to me in 5 days, no charge and sounds like normal again. Thanks!

I'm about to do the same. Need to take mine back to the dealership to readdress an issue that wasn't initially resolved. Early model 2010 with 18k miles.

I think my car has this issue. I just picked it up last sunday, and noticed the noise. I thought it might be the plate frame rattling, but after reading all the posts this sounds like I might need to have it looked at :(

I apologize for the inconveniences you may be experiencing. It would definitely be best to get it diagnosed by the dealership.

Please let us know how the visit goes.

It means you should have bought an v8

When I bought my Transformer edition it had the same noise they said it was a broken exhaust baffle and after getting in several that were bent up on the tail pipes they finally replaced it and the noise went away for awhile. After a road trip of 400 miles it came back now they say it is a known problem with the 4-6-8 system and will not fix it. Same problem same noise but after 5 assemblies they say I have to live with it. What the heck over 40 g's and I have to accept it. Not me I'll be back till they fix it.
