Customers may experience the following: ● The vehicle will not start and cannot be keyed off. NOTE: The vehicles 12V system remains powered up. The following software enhancements are also available: ● Improved diagnostic robustness of P0DAF-00. ● Increased maturation time for P0DE6-00 fault to cover extreme cold-start scenario where HV SOC drops low due to cold-cranking. ● Coordinated change with Electric Vehicle Control Unit (EVCU) to prevent high voltage battery drain during flashing events. This bulletin involves inspecting and possibly reprogramming the BPCM, Drive Motor Power Inverter (DMPI), EVCU and Powertrain Control Module (PCM) with the latest available software.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11032836-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11032836-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11032836","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["P0DAF","P0DE6"],"topics":[],"vehicles":[{"make":"JEEP","model":"CHEROKEE","year_from":2026,"year_to":2026,"match":"exact","vehicle_ids":["2026_jeep_cherokee"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
