There are plenty of cases where a dealership will deny a repair claim, but it\u2019s rare for a dealer to void a car warranty completely. Under federal law, your car\u2019s manufacturer can\u2019t just cancel your warranty because you used an unauthorized part or dealer. <\/span><\/p>\n

However, extended warranties work differently. Because they\u2019re technically vehicle service contracts, not true warranties, the provider may have more room to void your contract.<\/span><\/p>\n

\n

How federal law protects your factory warranty<\/h2>\n<\/div>\n

Factory warranties are a promise from your car\u2019s manufacturer that the car will work as expected. They guarantee certain repairs in case of mechanical failure or breakdown. They’re also called manufacturer warranties.<\/span><\/p>\n

The Magnuson-Moss Warranty Act is a federal law that protects your factory warranty. It states that a manufacturer can\u2019t deny a warranty claim (or void your warranty) because you used an aftermarket part or went to an independent mechanic for the repairs instead of the dealership. <\/span><\/p>\n

Under this law, the manufacturer must prove that the alternative part or service caused the issue. For example, if you install fun custom wheels, your manufacturer needs to prove that the wheels damaged the car\u2019s wheel bearings to deny your claim.<\/span><\/p>\n

Under factory warranty, you can have your car serviced anywhere, including at home. Just make sure to keep the fluid receipts and service records to make future claims easier.<\/span> <\/div>\n<\/div>\n

\n

Common reasons your car warranty claim could be denied<\/h2>\n<\/div>\n

These factors typically won\u2019t void your entire factory warranty, but there are a few reasons your manufacturer could deny a warranty repair claim:<\/span><\/p>\n

\n
    \n
  1. \n

    Neglect.<\/span> If you don\u2019t have proof that you maintain your vehicle at regular intervals, your claim might be denied. For example, if your engine fails, but you don\u2019t have records of oil changes, the manufacturer may assume that the failure is due to neglect.<\/span><\/p>\n<\/li>\n

  2. \n

    Misuse. <\/span>If the dealership can tell that you used the car in extreme ways, such as racing, over-revving, off-roading and ignoring towing capacity, they might deny a warranty claim.\u00a0<\/span><\/p>\n<\/li>\n

  3. \n

    Modifications. <\/span>Some modifications, like a new stereo system or window tint, don\u2019t tend to affect the rest of your car. However, if you install an aftermarket part that causes engine or transmission problems, for example, your warranty may not cover repairs.<\/span><\/p>\n<\/li>\n<\/ol>\n<\/div>\n

    \n

    Rare cases where your factory warranty could be voided <\/h2>\n<\/div>\n

    Your entire car warranty is unlikely to be voided in most cases. However, a few unique circumstances could get your warranty cancelled:<\/span><\/p>\n
