One of the most common questions and fears we get from customers or potential customers is a valid one: “Will adding aftermarket parts void my warranty?”

It’s a scary premise, and unfortunately one some uneducated dealerships seem to drill into their customers, that using non-OEM parts or upgrades will void the factory warranty, and leave you the new car owner to fend for yourself, without support from the vehicle maker.

Thankfully this isn’t the case, and there is legislation in place to protect you, the consumer, from these types of situations.  The Magnusson-Moss Warranty Act was passed way back in 1975 to combat this exact subject, and ensure that you have the freedom to choose aftermarket parts and upgrades without having your warranty stripped or voided.

Dealerships and car companies are required to prove that any modification of the vehicle with aftermarket parts is the cause of the failure.
