This can result in a loss of propulsion and may increase the risk of a crash. Software version verification, along with the installation of an upgraded circuit overlay harness kit, is required to address this issue.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11017896-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11017896-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11017896","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"PETERBILT","model":"520","year_from":2022,"year_to":2025,"match":"exact","vehicle_ids":["2022_peterbilt_520","2023_peterbilt_520","2024_peterbilt_520","2025_peterbilt_520"]},{"make":"PETERBILT","model":"579","year_from":2022,"year_to":2025,"match":"exact","vehicle_ids":["2022_peterbilt_579","2023_peterbilt_579","2024_peterbilt_579","2025_peterbilt_579"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
