AutoZone lists three different warranties in its Terms and Conditions: Limited Warranty, Duralast Gold and Duralast Battery Limited Warranty, and PROFormance Warranty. According to the Terms and Conditions page, most parts and accessories are covered by the AutoZone limited warranty.
AutoZone's Terms and Conditions page explains that AutoZone's parts and accessories are covered by its Limited Warranty, with the exception of those listed above. Also, the length of the limited warranty varies, depending on the part. Individuals have to search for the specific part or accessory on the website to determine the exact length of the warranty for that particular part. Furthermore, for replacement parts, there is a warranty of either 90 days or the remaining length of time on the original warranty, whichever is longer. The AutoZone limited warranty also expires if someone sells the vehicle.
The battery limited warranty expires either the date specified on the receipt or the day that one sells his or her vehicle. If a battery is found to be defective during the free replacement period, AutoZone provides a free replacement battery.
The PROFormance warranty provides three-year, unlimited mileage coverage for any cause of failure, either due to manufacturing or non-manufacturing problems. Individuals that face problems with products falling under the PROFormance warranty receive a replacement engine on the initial claim.
