This is a 1975 United States Federal Law which
deals with consumer warranty coverage. It defines responsibilities for both the buyer and the seller of all consumer
goods costing more than $25. A portion of this law applies to aftermarket parts and modifications and how it affects your
car warranty.
For our purposes the law basically states that you have a right to use aftermarket, non-OEM parts on your car and still
retain the factory warranty. However, if there is a failure and the manufacturer (Hyundai, in this case) can show that the
failure was caused by the aftermarket part, they can deny coverage.
The important thing is that your dealer cannot
VOID your entire warranty just because the part is on the car. There have been cases where a dealer would tell a customer
that their new car had no warranty because it had an aftermarket exhaust. Granted, the exhaust is not covered, however the
rest of the car is still under the normal warranty.
The bottom line is to talk to your dealer and get their feeling about aftermarket mods. Some
dealers are more prone to be ok with it than others.
