“The Magnusson Moss Warranty Act of 1975 lays out consumer warranty rights and does not allow manufacturers to set warranty coverage conditions on using factory-authorized parts or service. If a problem was caused by an independent mechanic or unauthorized part, it is the manufacturer’s obligation to prove it. (Read: “Can an aftermarket part void my car warranty?”)
If an automaker or dealer tries to insist that you use only dealer service or manufacturer parts to get warranty service, don’t believe it. And don’t hesitate to contact the FTC at ftccomplaintassistant.gov.”
