Can I use an independent mechanic without voiding the warranty?
Yes. Under the federal Magnuson-Moss Warranty Act, it is illegal for a manufacturer to void your warranty simply because you had routine maintenance or repairs done at an independent shop. However, you must ensure the shop uses correct fluids and parts meeting Manufacturer / engineering specifications, and you must keep all maintenance receipts. If a failure occurs, Ford must prove that the aftermarket part or independent work directly caused the failure to deny a claim.
