A violation of Federal Law
A quote from the Federal Trade Commission website:
An independent mechanic, a retail chain shop, or even you yourself can do routine maintenance and repairs on your vehicle. In fact, the Magnuson-Moss Warranty Act, which is enforced by the FTC, makes it illegal for manufacturers or dealers to claim that your warranty is void or to deny coverage under your warranty simply because someone other than the dealer did the work.

Went by my RAM dealer (Bremerton, WA) today to discuss a few problems with the service adviser. I happened to mention that I would be doing my own oil changes after the complimentary first change. Adviser made it quite clear that that would void my warranty because I would have no proof that the work had been done. I said that I would have receipts and the adviser said that was not proof that the work was actually done!
