Once the High Voltage battery has reached a 100% state of charge, the regenerative function will shut off and the electric drive motor load will be released. Under certain driving conditions, this release of load from the engine can result in sporadic misfire faults storing in the Engine Control Module fault memory. The production solution to this issue was improved software implemented into production.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10125728-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10125728-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10125728","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"VOLKSWAGEN","model":"JETTA HYBRID","year_from":2013,"year_to":2014,"match":"base","vehicle_ids":["2013_volkswagen_jetta","2014_volkswagen_jetta"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
