Does an UNDERHOOD compressor void my vehicle warranty?

A common question people ask before they buy a VMAC UNDERHOOD compressor is, “Does this thing void my warranty?”

Does an UNDERHOOD compressor, or any compressor or piece of equipment void the vehicle manufacturer’s warranty?  Great question.

The great news for anyone thinking of adding equipment to their truck is the answer is no.

For those of you in the United Sates, the Federal Trade Commission – Bureau of Consumer Protection – Division of Consumer and Business Education has published an article about something called the Magnuson-Moss Warranty Act.  This act puts the burden of proof on the dealer to show that the aftermarket equipment caused the need for repairs before denying warranty coverage.  You can find that article here.

For this particular topic, the paragraph referencing aftermarket parts is of interest.  It states:

Will using ‘aftermarket’ parts void my warranty? No. An ‘aftermarket’ part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer. Simply using an aftermarket part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket part. Still, if it turns out that the aftermarket part was itself defective or wasn’t installed correctly, and it causes damage to another part that is covered under the warranty, the manufacturer or dealer has the right to deny coverage for that part and charge you for any repairs. The FTC says the manufacturer or dealer must show that the aftermarket equipment caused the need for repairs before denying warranty coverage.

The people over at Tundra Headquarters have published an article walking you through the Magnusson-Moss Warranty Act.  You can find it here.  At the end of the day, aftermarket parts can’t void your warranty although if they are deemed to be the cause of a failure, that particular failure won’t be covered.

To be safe, buy aftermarket equipment from companies that are reputable and follow their instructions carefully.
