NHTSA Complaint #11634852 — 2022 NISSAN LEAF

After a recent software update, my vehicle's cabin heating system began malfunctioning. On cold days, when heat is most critical, the system suddenly stops providing heat and blows cold air (around 64°F) for the remainder of the drive. This issue compromises both safety and comfort. My car is still under warranty so I brought it to the vehicle to Eden Prairie Nissan. Initially, the technician claimed I was not performing the "proper starting procedure" (keeping the blower speed low for the first few minutes). However, the provided owner’s manual supplement makes no mention of such a procedure affecting the heating system. After speaking with the dealership manager, I learned that other Nissan Leaf owners are experiencing the same issue. I was informed that the problem is an unintended consequence of a software update designed to prevent overheating. Despite following the dealership's instructions, the issue persists. For example yesterday during a 20-minute drive, the heating system stopped after five minutes, even with the blower on the lowest setting it was 9F outside.This morning during a round trip to an appointment, the system provided no heat at all 11F outside. Thank you for your attention to this matter. Please let me know if additional details or documentation are required.
