Widespread availability will be a couple of weeks in the process.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10152494-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10152494-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10152494","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MCI","model":"J4500","year_from":2017,"year_to":2019,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
