What Can Void Your Specific Parts Warranty


Some people are so unconcerned about their automobiles’ demands that they spend years without getting an oil change. Avoid this at all costs if your car is still under warranty. The dealer is not responsible for any damage to your engine if you neglect to take your vehicle in for service during its regular maintenance.

Use of Dirty or Improper Fluids

The warranty does not cover any harm caused by accidentally putting sugar in the gas tank or spacing out and putting diesel fuel in your gasoline. Always check your owner’s manual to make sure you’re using the suitable fluid.

Aftermarket Parts or Modifications

There is much gray area in this area of warranty coverage. Despite what many dealers would have you believe, installing an aftermarket part or having modifications on your vehicle does not void your warranty.

Some sellers may claim that just because you have a performance part on your car, such as a cold air intake, your entire vehicle warranty is worthless. However, this is not the case. Before they can deny you warranty coverage, they must prove that the aftermarket equipment in your car caused the need for repairs, according to the Magnuson-Moss Warranty Act of 1975.

If the cause of a part failure is unknown, however, a dealer will almost always charge you to diagnose the car. If the aftermarket equipment was not installed properly or a modification caused a component failure, the dealer has the right to invalidate the warranty for the part, and you will be responsible for the repairs. On the other hand, you will be repaid the diagnostic fee if the aftermarket parts have nothing to do with the repair issue.

Any aftermarket parts on your vehicle may lead the dealer to believe that you are driving it hard or racing it. It is thus always advisable to research dealers who are more mod-friendly if your car has modifications on it and requires a repair.
