The invented rule
Ask drivers who've fought a second claim and you'll hear the rule stated as fact: one exchange only. Staff have said it at the counter; a customer had it confirmed at a second store. So we read the documents. All four chains' published warranty texts. The cap is not in any of them.
O'Reilly, in writing: a warranty replacement is itself covered for 90 days or the remainder of the original period, whichever is greater. A document that gives the replacement its own coverage is a strange place to hide a one-exchange cap. AutoZone, in writing (batteries): the replacement's warranty runs from the original purchase date — a shrinking window, not a vanishing one. Advance and NAPA: no exchange-count rule appears in the published texts this site verified.
The true statement underneath the myth: repeat claims get scrutinized — each failure re-graded on its record, its test, its pattern. Scrutiny is real. A count cap is not.
Because it ends conversations, and because its kernel — the shrinking replacement clock — feels like a cap from the customer's side of the counter. A battery replaced at month 34 of a 36-month free window has 2 free months left; the next failure feels like "no more exchanges" even when the written position is "2 months of window." The replacement-clock page lays out each chain's rule.
"Show me the cap in the written warranty." Said politely, with the part and the record in hand, it is the whole play: a rule the store can't produce is a ruling corporate can review. Then get the actual ruling — the failure finding — in writing, and climb: numbers for all four chains are on the ladder page.
Not sure which wall you hit? The free checker sorts it in a few picks — chain, part, purchase date, your proof, and the store's own words — and gives you where you stand under the written policy, the proration math where it applies, the exact next counter move, and the ladder above the store.
