Nissan Leaf owners warned to avoid DC fast charging after fire-risk recall

A sudden shock for Leaf owners

Nissan is recalling 19,077 2021–2022 Nissan Leaf vehicles because some lithium-ion battery cells can overheat during Level 3 (DC fast) charging. Nissan is advising owners of potentially affected vehicles to avoid using Level 3 (DC fast) chargers until a software remedy is installed.

Interim owner letters are scheduled to be mailed beginning October 24, 2025, instructing customers not to use Level 3 (DC fast) charging until the remedy is completed. The NHTSA states that some battery cells may have excessive lithium deposits, which increase electrical resistance.

During Level 3 charging, this resistance can cause rapid heating and, in some cases, lead to a battery fire. Therefore, Nissan advises owners to avoid Level 3 charging until the software remedy is deployed. This recall has left many EV owners frustrated and worried about safety.

What’s really causing the issue

The main problem lies inside the Leaf’s lithium-ion battery. Engineers discovered that some cells have excessive lithium deposits, leading to increased electrical resistance.

That resistance makes the battery work harder and heat up faster, especially when using high-speed chargers. When temperatures rise too much, the battery can enter what’s called a “thermal event,” which means it could catch fire.

The buildup likely happened during the manufacturing process, but Nissan hasn’t shared exact details. What’s clear is that these deposits interfere with the battery’s ability to charge smoothly, making it risky to plug into a fast charger.

Drivers won’t see any warning signs

One of the scariest parts of this problem is that there’s no way for drivers to spot it in advance. No lights, alarms, or alerts appear on the dashboard before the vehicle overheats.

That means the issue could build silently while fast charging, giving owners no time to react. As a result, Nissan is strongly advising against using DC fast chargers until the software update is installed.

For the 2021–2022 vehicles, NHTSA’s filing indicates that there may be no preceding warning to customers. In contrast, earlier 2019–2020 vehicles sometimes displayed signs such as smoke, noise, or thermal odors, suggesting that the presence or absence of warnings varies by model year and circumstance.

Which Leafs are on the list

The recall affects 2021 and 2022 Nissan Leaf models made at the Smyrna, Tennessee, plant. Both the 40-kilowatt-hour and 62-kilowatt-hour versions are included. Both the 40-kWh and 62-kWh battery options were offered on U.S. LEAFs during 2021–2022 and are listed as affected in NHTSA’s filing.

Owners can check their VIN on the NHTSA or Nissan recall lookup tools. The NHTSA indicates that VINs will be searchable beginning October 4, 2025, and interim owner letters will be mailed starting October 24, 2025, with invitation-to-repair notices issued when the remedy is ready.

While newer Leafs aren’t part of the recall, the situation has many wondering if older batteries could eventually face a similar problem down the road.

Why fast charging matters so much

For many owners, Level 3 (DC fast) charging is critical; DC fast chargers can typically add most usable charge in tens of minutes (commonly 20–60 minutes to reach a high state-of-charge, depending on the charger’s power and the battery’s size), so losing that option is a significant inconvenience.

Losing that option means longer charging times and less convenience. Level 1 or Level 2 charging at home can take several hours, sometimes overnight, depending on the setup.

This recall requires a significant lifestyle change for some drivers. Until Nissan delivers its software fix, owners will have to plan trips carefully and rely on slower but safer ways to keep their cars powered up.

What Nissan’s fix will actually do

NHTSA describes the remedy as software that will ‘prevent progression to thermal incident’; dealers will perform the update free of charge once it is available.

The system will monitor internal temperatures and prevent the cells from reaching dangerous levels. This digital safeguard could allow fast charging again once installed. The update will be available for free at dealerships as soon as testing is complete.

While no hardware replacement is needed, Nissan wants to ensure that the software prevents future fires. Until then, the company is asking owners to be patient and follow the temporary safety guidance.

How owners will be notified

The recall process will happen in two steps. First, Leaf owners will receive letters this month confirming their vehicles are included in the recall. Later, a second letter will be sent to announce when the software fix is ready.

HTSA lists a phased recall schedule; interim letters are scheduled to begin on October 24, 2025, and VINs became searchable on October 4, 2025. Each dealership will handle the update at no cost to the owner.

In the meantime, Nissan is reminding customers to stick with Level 1 or Level 2 charging only. It’s a frustrating wait, but the goal is to make sure every affected Leaf can charge safely again soon.

A problem that keeps returning

This isn’t the first time the Leaf has faced this issue. A similar recall in 2024 covered 23,887 LEAFs from model years 2019–2020 (NHTSA 24V-700).

Now, another 19,077 cars have been added, bringing the total to nearly 43,000 Leafs at risk. Each recall points to the same root cause, lithium buildup in the battery cells. That consistency suggests the problem has been around longer than expected.

Nissan insists that only about one percent of affected cars will exhibit the defect. However, owners are still advised to avoid fast charging altogether until the final software update is released.

Why the issue keeps happening

Experts believe the problem starts during the battery’s manufacturing process. Slight differences in temperature or chemistry can cause lithium to cluster unevenly inside the cells.

Over time, these clusters increase electrical resistance, leading to excessive heat. Once the battery starts overheating, the process can accelerate rapidly under fast-charging conditions. Even with strict quality checks, battery production is complex, and tiny flaws can slip through.

NHTSA’s report lists Automotive Energy Supply Corporation as the battery supplier for the affected packs. Nissan has not announced any supplier changes, and the company states that it is investigating the root cause.

What makes Level 3 charging risky

Level 3 chargers, also known as DC fast chargers, deliver a substantial amount of power in a short period. This high-speed energy transfer generates more heat than slower chargers.

That’s usually safe with well-balanced batteries, but when internal resistance increases, the heat can rise too fast. Once a battery gets too hot, chemical reactions inside can spiral out of control. That’s why Nissan and safety officials are taking no chances.

Until the update is ready, fast charging any affected Leaf could risk overheating. It’s a reminder that battery technology needs precision at every level.

What Nissan is saying publicly

Nissan has promised customers that a fix is coming soon and that safety is its top priority. A company spokesperson said the software update is in the final stages of testing before rollout. Once installed, it will allow drivers to use Level 3 chargers safely again.

Nissan says it understands the inconvenience and is working with dealers to speed up repairs. The company also stressed that all recall work will be done free of charge. This latest setback comes at a sensitive time, as Nissan prepares to introduce its redesigned next-generation Leaf later this year.

Battery safety across all EVs

The Leaf recall isn’t just a Nissan issue; it’s a wake-up call for the entire electric car industry. As automakers strive for faster charging times and higher performance, heat management becomes increasingly challenging to control.

Battery chemistry is complex, and even minor imbalances can create significant safety issues. Other brands have faced similar challenges, from overheating to charging system failures.

Experts say the next step is to develop more innovative battery software that constantly monitors for early signs of trouble. These systems could become standard across all EVs, ensuring that drivers stay safe without giving up the convenience of fast charging.

How to check your Leaf

If you own a 2021 or 2022 Leaf, you can find out if your car is affected by entering your VIN on the NHTSA recall website.

Nissan will also send printed notices by mail. Some owners have already received the first letter, which urges them to stop using fast chargers immediately. When the fix is ready, you’ll be invited to schedule an appointment at a local dealership for the free update.

It’s a quick process, but until then, stick to slower charging methods and avoid any public DC chargers, even if your battery seems fine.

Owners react to the recall

Many Leaf owners have taken to online forums to share their frustration about the situation. Some rely heavily on fast charging for work or travel, and losing that option feels like a significant setback.

Others are just relieved that Nissan caught the issue before any serious accidents occurred. Drivers say they appreciate the free fix but wish the update had been ready sooner.

While some EV fans view this as a temporary setback, others worry it could erode confidence in electric cars that rely heavily on reliable battery technology.

The future of the Nissan Leaf

Nissan’s all-new 2026 LEAF features a liquid-cooled lithium-ion battery (up to 75 kWh), faster charging, and revamped thermal management, according to the official U.S. press kit.

The upcoming model is expected to charge faster while staying cooler, using upgraded software to monitor every cell. Nissan hopes this new version will restore confidence among EV buyers.

Even with the current challenges, the Leaf remains a key part of Nissan’s electric lineup and continues to be one of the most affordable EVs on the American market.
