NHTSA Complaint #11699598 — 2021 NISSAN LEAF

The dealership without our knowledge or approval did an update on our car last November that makes the heater and more importantly defroster not work when it's colder than about 17F degrees outside. This causes the vehicle to fog up all over including the windshield making it dangerous to drive. After about 10 minutes it finally starts working. We've told them about it numerous times and even saw other Leafs at the dealership for the exact same thing on the first cold day last winter after the update. They haven't yet gotten a fix for it and said it's on purpose. As far as us owners can tell they aren't looking into any sort of fix. They say we should just start the car for 10 minutes without driving but that doesn't work. You can leave it run for 30 minutes and the heat doesn't turn on. It only works after 10 minutes of dangerous driving. Besides we shouldn't have to run a vehicle for 10 minutes before driving. There are numerous examples of emergencies that require immediate driving. Please look into this as every Leaf owner is dealing with the same dangerous conditions in the northern states and I assume Canada.
