NHTSA Complaint #11627966 — 2020 NISSAN LEAF

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.
