When I hear dealers use that old standby BS about voiding warranties it just frustrates the hell out of me since they are speaking out of their butts. Anybody being told that BS should tell the dealer they need to look up " The Magnuson-Moss Warranty Act". Quote from the Act " Commission staff has recently issued a number of guidance documents to better educate consumers and businesses concerning their rights and obligations under the MMWA. For example, in order to cure perceived misconceptions in the marketplace, staff issued and recently updated a consumer alert stating that the MMWA prohibits warrantors from voiding an automotive warranty merely because a consumer uses an aftermarket or recycled part or third-party services to repair one’s vehicle."
Sorry, done ranting now...Time for my meds.
