Rattiling from the break and gas pedals?

[3Hummer]

Anyone have a similar problem? Today on my way back from school my gas and break pedals were rattling and shaking like crazy, and i was able to hear it a little as well. I took it into the dealership and the second I got there the rattiling stopped, so at Hummer they called OnStar and had them run a scan of the car and they said they found nothing wrong with it. After I left the rattiling starting again but only very minimal, If it gets worse I'm going to call OnStar up again and go back to the dealership. But in any case anyone have this happen to them, and does anyone know what it is? Thanks.

I would be concerned if that happened to me. I like my brake pedal to be still as I am trying to stop. Take it back to the dealer and have them drive it (ALOT).

I did, and we drove like 10 miles or so and nothing happened it stopped like as i was pulling into the dealer, also the sales guy wasnt nice at all he picked up the phone as he was talking about it and then stayed on the phone the entire time and was driving my car like crazy so i had him turn back to the dealer, i have to wait till monday till the other service guy is there, but the rest of today it was fine so unless it gets really bad i think ill be fine till monday and if it feels really bad if i drive it over the weekend ill just have to use my moms car!

I think you should determine if its an engine vibration causing pedal noise, driveline noise or is it a weird stretch of road. My experience is no one gives a shxt at the dealers unless they're pushed a little. Sometimes you gotta be your own mechanic. Regards The Reb:(

I know it isnt a certain stretch of road cuase it did it on my way from school to pick up my sister and then on the way to the Hummer dealership, so i dont think it was a road becuase that whole trip for me is like 30 miles and it nevers happened before over the same road.
