Will This Mod Void My Warranty?

[Apex Chase]

This is a question we get asked often and is a major concern for many people as they start down the road of modifying their vehicle. Search the web and you will find plenty of answers from the internet “experts”, but as usual most of them are incorrect. So, what is the answer?

Despite all the bad information out there, it is pretty cut and dry because there is federal law on the matter. The Magnuson-Moss Warranty Act (15 U.S.C. 2302(C)) regulates warranties and protects the consumer. This legislation was enacted in 1975 in response to widespread deceptive warranty practices in many industries. Here is how SEMA summarizes things:

The essence of the law concerning aftermarket auto parts is that a vehicle manufacturer may not condition a written or implied warranty on the consumers using parts or services which are identified by brand, trade, or corporate name (such as the vehicle maker’s brand) unless the parts or service are provided free of charge. The law means that the use of an aftermarket part alone is not cause for denying the warranty. However, the law’s protection does not extend to aftermarket parts in situations where such parts actually caused the damage being claimed under the warranty. Further, consumers are advised to be aware of any specific terms or conditions stated in the warranty which may result in its being voided. The law states in relevant part: No warrantor of a consumer product may condition his written or implied warranty of such product on the consumers using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name… (15 U.S.C. 2302(C)).

So in short, this means a service department or automotive manufacturer can not void your warranty simply because you have installed aftermarket parts or have modified your vehicle. They can, however, deny a warranty claim if they can prove the issue in question was a direct result of the installed part or modification. Unfortunately, plenty of people have stories of going to a dealership service department with a warranty issue and being denied because they have modified their vehicle. There are definitely shady service departments out there who will try to get over on their customers if they can, but this is illegal and it is up to the customer to know the law and stand up.


Here is an example of what can not be denied:

You install a supercharger in your vehicle and a month later your drivers side window stops working. The supercharger has no impact on your electric window motor, therefore, the repair should be covered.


Here is and example of what could be denied:

You install a supercharger in your vehicle and a month later your clutch is toast. The additional power created by a supercharger can easily overpower a stock clutch and lead to the repair not being covered under warranty.


So what do you do if you are illegally denied a warranty repair? According to the law, if the repair is over $25 you lawyer up and file a lawsuit in federal court. However, it is much easier to just take you business to dealership that treats their customers fairly. They do exist.

There is a great deal of confusion regarding vehicle modifications and manufacturer warranties on the Internet. What follows are some simplistic clarifications to help consumers navigate the murky waters of vehicle modifications and warranties.


Magnusson-Moss Warranty Act: This act provides a host of benefits for common consumers, and some protections for automotive enthusiasts as well. The Magnusson-Moss Warranty Act may be viewed as a federal "lemon law" (California's state lemon law is the Song-Beverly Consumer Warranty Act). Lemon laws serve the basic function of protecting the consumer from vehicle defects and improper warranty denial or abuse.


Magnusson-Moss provides that before a manufacturer can deny warranty coverage as a result of a vehicle modification (e.g., aftermarket exhaust or wheels), the manufacturer must provide proof or evidence that the aftermarket part caused or contributed to a warranty concern or issue. [*Please check your owner's manual for the extent and duration of all vehicle warranties before attempting to assert protections provided by Magnusson-Moss.]

For example, if you have an aftermarket exhaust, and you take your car to the dealership to service a transmission issue, the manufacturer must demonstrate a causal link between your aftermarket exhaust and the transmission issue in order to deny warranty coverage that would have addressed the transmission issue.


In the event that an aftermarket part or component is found to have caused or contributed to a warranty issue, then the warranty for that specific manufacturer part is no longer valid; the warranty for the rest of the vehicle still remains in effect. For example, a manufacturer cannot void your powertrain (engine/transmission) warranty because you installed an aftermarket stereo head unit and amplifier in your car, and your factory speakers are now blown and no longer functional. Only the portion of the manufacturer's warranty for the vehicle's factory (original) sound system is affected. Your powertrain warranty remains intact despite the fact you modified the interior of your car, damaged the factory speakers, and no longer have warranty coverage for your factory/original sound system.


Real World Implications: Despite the protections provided by Magnusson-Moss, many automotive dealerships (which are independently owned and operated) will attempt to void vehicle warranties (or refuse service under warranty) because of aftermarket parts or modifications because they know that many people are not aware of their rights, will not go through the trouble of fighting the dealership and/or manufacturer, or do not want to wait to have vehicle service performed at a later date. *Remember that your vehicle warranties are through the manufacturer, and that the dealership is compensated by the manufacturer for warranty service when the service is approved by the manufacturer or its service divisions.


Preventative Solutions/Tips:
1) Try to have your vehicle serviced at a dealership that is fair and reasonable with respect to vehicle modifications. Inquire as to the dealership's stance regarding modifications before going in for service with aftermarket parts installed. Some dealerships are owned by enthusiasts and they appreciate the modifications performed by owners, and other dealerships don't want to deal with the potential liability or headaches that come with servicing modified vehicles under warranty. There are many dealerships that take no issue with modifications such as air intakes, cat-back exhausts, lowering springs, and aftermarket wheels, but draw the line at more involved modifications such as forced induction or aftermarket tunes. Conversely, there are dealerships that will take issue with minor modifications such as an aftermarket air filter or an axle-back exhaust.


2) Certain manufacturers provide branded performance parts such as intakes and lowering springs from in-house racing developers or third party affiliates such as TRD or STi. Performance upgrades from these sources are often backed with factory warranties so long as they are installed by a dealer. This is one potential way to avoid warranty hassles, but the trade-off is that these upgrade parts are limited in application and can be rather expensive.


3) Some dealerships will even install aftermarket (not from TRD or STi) parts for you, but be aware that if something goes wrong, and a warranty issue arises, all bets are off regarding your treatment by the dealership. If possible, get a written representation from the dealership that installed the aftermarket parts that you will be covered in the event of a subsequent warranty issue.


Editor's note: Organizations such as SEMA can provide you with more in-depth information and additional resources regarding the aftermarket industry and aftermarket parts.

Your warranty booklet should say, or just ask a dealer
