I just got an 05 with 49k miles and my cruise control is rattling. I read the fix, Cruise Control Buzz DIY Fix, but I also read a lot of people saying that it was fixed by dealerships for free because of a TSB. I called my local dealership and asked them about it but when they searched on my VIN they said that there were no open issues with the car. They also said that they had never heard of the problem and that it would not be covered under warranty. So I am wondering if it was in fact something that should be fixed under warranty or because of a TSB and if so could someone post more info on that. Thanks.
