Original source, historical coverage and missing authority
Original public bulletin rechecked 29 October 2026. No newer revision was established by the bounded search; this is not a claim that the document is current service information. The stated original warranty was 96 months/80,000 miles from in-service, whichever first. Ordinary 2010-vehicle coverage is historical in 2026; no present eligibility is verified.
