• Like other retailers of branded products, RockAuto does not offer any product warranty of our own--we honor the warranty provided by the manufacturer of the product. If you have a problem with a part during the warranty period, please contact us and we will arrange a return and replacement.
• The summary below does not include all the terms and limitations of each manufacturer's warranty, and manufacturers may change their warranty terms without notice (to you or to us). For warranty details, please visit the manufacturer's website.
• Warranties apply only to the original purchaser of the part and the vehicle on which the part was originally installed.
• Warranties begin upon delivery.
• Terms listed apply only for parts used on a private passenger vehicle; warranties for cargo, commercial or off-road vehicles may be more limited.
• Warranties offer only replacement of the defective part with another part: no cash refunds and no reimbursement of labor costs, shipping costs or other expenses.
• Replacement under warranty does not extend the warranty term.
• Wholesaler Closeout items have a 30 day warranty (but still are covered by our Return Policy).
