On affected vehicles, at temperatures below -10°C/14°F, use of the blower motor at full speed can cause the defrost function to operate at a low electrical current and trigger failsafe logic. This may result in reduced defrost performance. Dealers will update the HVAC control software. *****What Dealers Should Do***** 1. Verify if vehicles are affected by this service campaign using Service Comm or DBS National Service History – Open Campaigns I.D. P4A17 • New vehicles in dealer inventory can also be identified using DBS (Sales-> Vehicle Inventory, and filter by Open Campaign). • Refer to NPSB 15-460 for additional information • Please continue to check newly arriving inventory for campaign applicability. 2. If a retailed vehicle affected by this Campaign ID visits the dealer for service, the dealer should inform the customer about the service campaign and communicate that the updated software is available. 3. Once remedied, dealers should submit the applicable warranty claim for the action performed so it can be closed in Service Comm and release the vehicle to the customer.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11012290-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11012290-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11012290","components":[{"id":"visibility","name":"Glass, wipers and mirrors","parent":null},{"id":"wiper","name":"Wipers and washers","parent":"visibility"}],"codes":[],"topics":[],"vehicles":[{"make":"NISSAN","model":"LEAF","year_from":2018,"year_to":2025,"match":"exact","vehicle_ids":["2018_nissan_leaf","2019_nissan_leaf","2020_nissan_leaf","2021_nissan_leaf","2022_nissan_leaf","2023_nissan_leaf","2024_nissan_leaf","2025_nissan_leaf"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
