Education only. PartsWarrantyDecoded publishes general information about auto-parts warranty terms and claim tactics. It is not legal advice, not a claims-adjusting or advocacy service, and not a substitute for a consumer attorney where one is warranted (for example, claims involving injury, fire, or consequential damage beyond a part's price).
Not affiliated. We are not affiliated with, endorsed by, or employed by AutoZone, Advance Auto Parts, O'Reilly Auto Parts, or NAPA. Trademarks and trade names belong to their owners and are used to identify the publishers of quoted warranty terms.
Likely rulings, not promises. The checker and the Kit state likely rulings under published terms. Stores apply terms unevenly; managers hold discretion the documents don't describe; examiners decide NAPA tag claims on inspection. No outcome is promised, and no page here should be read as one.
Your documents control. Warranty terms are era-stacked: the terms in force at your purchase, as printed on your receipt or its accompanying documents, govern your claim. Where those printed terms differ from a general statement here, the printed terms win — several pages on this site say exactly that, because it is the single most useful sentence in this field.
