2020 Nissan Leaf

SAFETY COMPLAINT / INCIDENT DESCRIPTION Vehicle presented to Dennis Dillon Nissan on June 20 2026 for a factory high voltage battery recall software update intended to fix Level 3 fast charging safety risks. The software update rendered the vehicle completely inoperable by disabling standard Level 2 charging. The vehicle has been held in continuous dealer custody for 58 consecutive days without a working repair. Nissan failed to disclose that the recall patch could brick a functioning EV. Loaner support was revoked prematurely forcing 850 in out of pocket rental costs. Inadequate buyback offer via Morley Companies was rejected. Factory recall update rendered vehicle useless and unsafe to operate.

I am unable to use my 2020 Nissan Leaf because of the recall (R24B2) on the battery preventing fast charging. My child has the vehicle and now lives in an apartment and there is no place to plug in my car overnight. So the only option for my child is to fast charge it. I'm frustrated that this recall is almost 1 and a half years old and there is still no remedy.

On November 5, 2025 our 2020 Nissan LEAF (42,701 miles) experienced rapid loss of battery capacity under normal driving/temperatures (80F.) Vehicle defaulted to "turtle mode" temporarily, an unsafe condition. Were able to replicate condition on subsequent days. Took vehicle to Cedar Park Nissan for evaluation. Technicians concluded that the traction battery had one or more defective cells and recommended battery pack replacement. Vehicle is inoperable. Started complaint with Nissan customer assistance. Dealer and Nissan refused use of a loaner vehicle, despite offering no timeline on repairing/replacing the battery pack. The defect in our vehicle's battery cells may lie in the battery chemistry and be related to issues associated with damage from DC fast charging (recall 24V-700.) Our vehicle has seen little or no fast charging, being charged mostly on Level 1 or Level 2.

We have an open recall for the DC fast Charging for the last year. I use my car for work and often need to fast charge and haven’t been able to and so have to use another vehicle. This has caused a lot of stress and problems for work over the last year and Nissan have failed to address. I am also then concerned about resale value for the vehicle

I have previously had an issue with low resistance of the high voltage battery. This resulted in the car giving a warning code that prevents the restart of the vehicle once it's turned off. This is itself potentially leaves a driver in an unsafe location if they are in an isolated place since you are also unable to charge. I took it to the dealer multiple times and it took them almost a month to determine the vehicle did have an issue, that it needed 8 modules out of around 24 total replaced. These modules were replaced and the vehicle was returned to me. In spite of this the vehicle when under 50% capacity still exhibits erratic range and capacity readouts when under heavy load. The vehicle has been returned to the dealer and is under investigation again because it is unsafe to drive in this condition. There is currently an outstanding recall for high internal resistance when dc charging. This is the same resistance the battery has at all times so to assume it will only be a charging issue and not discharging is disingenuous. Any time a high load, either going into or out of, the battery a high internal resistance will lead to a cascading failure. The only repair is either replacement or the battery or derating the battery. The latter would vastly decrease the capabilities of the vehicle.
