2020 Nissan Leaf Fuel System Problems

Owner reports

Selected complaints filed with NHTSA by 2020 Nissan Leaf owners, lightly cleaned up (personal details are redacted by NHTSA).

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. …

To Whom It May Concern, I am writing to formally submit a complaint regarding an unresolved safety recall affecting my 2020 Nissan Leaf, currently with approximately 30,000 miles. The recall in question addresses a battery overheating risk associated with Level 3 fast charging (CHAdeMO), which Nissan has acknowledged and advised owners to avoid until a solution becomes available-scheduled for November 2024. I have contacted my local dealership, Flow Nissan of Fayetteville (4559 Raeford Rd, Fayetteville NC, 28304 - Tel: [phone]), multiple times requesting assistance during this period. Unfortunately, the service department informed me that no temporary solution or loaner vehicle could be provided, stating that Nissan National has yet to authorize support. As a member of the U.S. Air Force Reserve, this situation poses a serious hardship. …

Note: Searching for similar complaints I found them under "Engine", "Electrical", and "Fuel". There are many such complaints! My 2020 Nissan Leaf has been under a recall notice since September of 2024 (12 months ago). Nissan warned the battery may catch fire during level 3 (rapid) charging. Nissan ordered owners not to use rapid chargers until a fix was in place. Such a fix was (and still is) promised by March 2025. That date is 6 months past now and yet their website still proclaims it. This, to me, demonstrates that Nissan is not actively working on the problem. They seem content to have shifted the burden of dealing with the problem onto their customers. Rapid charging is not a luxury, especially with large capacity batteries. Fully charging the car in 2-3 hours instead of 10-12 hours is a key selling point of the vehicle. To remove it amounts to a bait and switch. …

In fall 2024 we noticed our Nissan Leaf starting to no longer be able to hold a charge. There were no warning lamps, messages, or other symptoms prior to this problem. It would go from fully charged to zero with no warning (including when driving on the highway) and would stop accelerating above 35mph. This was stressful and unsafe. It took 5+ months to "repair" the battery at the dealership, only to have the same issue occur again a few months later. This time the dealership "fixed" the issue in a little over a month, only for us to drive it home and immediately have the issue occur again (on a busy highway - thankfully no one in my family was injured or killed). The car is currently at the dealership for a third time. Combine this issue with an active recall on the charging system for over a year with no known fix, this vehicle no longer feels safe for my family. …

My 2020 Nissan LEAF is subject to open safety recall 24V700 / R24B2 for a high-voltage lithium-ion battery defect that poses a fire risk during Level 3 quick charging. On [redacted], I brought the vehicle to an authorized Nissan dealer for the recall remedy. Three days later, on [redacted], while driving from New Hampshire to Connecticut, the vehicle displayed a "Service EV" warning and entered a reduced-power (limp) state on the highway, creating a hazardous condition in traffic. A separate authorized Nissan dealer diagnosed a fault in the high-voltage battery pack. The vehicle is now undrivable and cannot be charged. Nissan has been unable to supply a replacement battery and has indicated the vehicle will likely be repurchased because the recall remedy is unavailable. …

Can't use fast-charging! I am filing this complaint regarding Nissan's failure to resolve the DC fast charging issue affecting my 2020 Nissan Leaf. In October 2024, Nissan issued a recall for nearly 24,000 Leaf vehicles due to a fire risk linked to Level 3 fast charging. Nissan advised owners to stop using fast charging and promised a software update by November 2024 to fix the issue. It is now March 2025, and Nissan has yet to deliver the promised fix. As a result, I cannot safely use a key feature of my vehicle, which significantly impacts its functionality and usability for long trips. This continued delay has caused major inconvenience and has left owners without a solution for months beyond Nissan's stated timeline. I am requesting that the NHTSA investigate Nissan's failure to resolve this issue and hold the company accountable for not providing a timely fix. …

I own a 2020 Nissan Leaf affected by recall 24V-700 (Nissan R24B2). The recall opened in September 2024 because the high-voltage battery can overheat and catch fire during Level 3 fast charging. Owners were told not to use fast charging until a remedy is available. The recall has been open since September 2024 and there is still no available remedy. Nissan has pushed the fix date repeatedly, first to November 2024, then Spring 2025, and now an unspecified point in 2026, with no firm date and no working repair at the dealer. I bought this vehicle more recently and understood there was an open recall, but a recall is supposed to mean a fix is coming, not a safety defect left unresolved for over a year and a half. In the meantime I am paying for a vehicle whose fast-charging capability I cannot safely use. This is well past any reasonable time to remedy a known safety defect. …

This vehicle is subject to Safety Recall 24V-700 (Manufacturer Recall R24B2) due to a defect in the lithium-ion battery that can cause a fire during Level 3 DC Fast Charging. Since the initial notice, I have received four separate recall communications from the manufacturer, yet as of March 2026, no permanent remedy has been provided. The manufacturer's only "interim" solution is an instruction to refrain from using the Level 3 DC Fast Charging (CHAdeMO) feature. This has effectively disabled a primary advertised function of the vehicle and creates a substantial safety risk should the port be used. This defect has rendered the vehicle unsellable on the secondary market and significantly impairs its daily utility, as I am unable to use charging infrastructure at my place of employment. …

I have been waiting since September 2024 to use my level 3 charger port again. I can't safely use it without a risk of fire severely limiting the cars use and range. On top of this my main battery was tested at the Nissan Dealer November 2025 and needs replaced under warranty. It will rapidly lose charge when on the highway potentially leaving me stranded on the side of a busy road. I only have about 30% usable battery and cant Level 3 charge without risk of fire. I have been waiting almost 2 years now and feel Nissan has exceeded a reasonable amount of time for both repairs. This is my only car and I cant continue driving it like this. I was informed of the charging issue by recall notice and started seeing the battery issue Summer 2025. If they ever do fix this, I'm going to have a hard time trusting driving it on the highway. …

The vehicle is affected by an unrepaired safety recall involving the high-voltage battery during Level 3 quick charging. The recall states that affected vehicles may develop excessive lithium deposits in battery cells, increasing electrical resistance and potentially causing rapid battery heating while Level 3 quick charging. The recall also states that if quick charging continues, a battery fire may occur, increasing the risk of injury. The recall status remains incomplete with the remedy not yet available. Owners are instructed not to use Level 3 quick charging through the CHAdeMO connector until the remedy is completed. This removes the vehicle's fast-charging capability and leaves the vehicle subject to an unresolved battery safety recall. The vehicle is available for inspection upon request. …
