Warranty Claim Requirements To keep claims fast and fair, we require: Proof of purchase (invoice or order confirmation). Photos or videos showing the defective part, order number, date, VIN, and odometer reading. Diagnostic reports or part returns for non-visible issues may be requested. Claims must be truthful, properly documented, and reflect normal consumer use.
