Nissan LEAF Fast Charging Lawsuit Dismissed Over CHAdeMO Battery Fire Claims
A federal judge in California has dismissed a proposed class action lawsuit involving 2019–2022 Nissan LEAF vehicles equipped with CHAdeMO Level 3 fast charging systems. The lawsuit alleged that Nissan sold LEAF vehicles with defective batteries that could overheat and potentially catch fire during DC fast charging, and that Nissan’s recalls failed to adequately solve the problem.
The ruling is significant because it highlights the growing tension between EV manufacturers attempting to address battery safety concerns through software updates and owners who argue they paid for functionality that they can no longer safely use.
What’s the Problem?
The lawsuit centered around Nissan LEAF vehicles equipped with CHAdeMO fast charging ports. Owners alleged the vehicles’ lithium-ion battery systems could overheat during repeated Level 3 fast charging sessions, creating an alleged fire risk.
According to the complaints, Nissan issued recalls that effectively warned owners not to use Level 3 fast charging until repairs became available. Plaintiffs argued this dramatically reduced the usefulness and convenience of the vehicles because fast charging was one of the primary reasons consumers purchased the LEAF in the first place.
The affected vehicles included:
2019 Nissan LEAF
2020 Nissan LEAF
2021 Nissan LEAF
2022 Nissan LEAF
All specifically equipped with CHAdeMO Level 3 quick charging capability.
Allegations
The plaintiffs alleged Nissan knew before sale that the LEAF battery systems were susceptible to overheating during rapid charging but continued selling the vehicles without properly disclosing the risks.
The lawsuit also claimed:
Nissan’s recalls did not truly repair the issue
Software updates merely limited charging functionality
Owners lost access to a key advertised feature
The vehicles allegedly lacked proper active thermal battery management systems
Nissan concealed the alleged defect from consumers
Plaintiffs argued the only real solution would be battery replacement or vehicle repurchase.
Recall / TSB
Nissan first issued a recall in 2024 involving certain 2019–2020 LEAF vehicles after determining batteries could overheat during Level 3 charging. Nissan later expanded the recall to include certain 2021–2022 models.
According to reports, Nissan warned owners to avoid using CHAdeMO DC fast charging due to fire concerns while the company worked on software-based remedies.
Some owners criticized the recall process because the proposed fixes allegedly reduced charging speeds or functionality rather than replacing battery hardware. Online owner discussions reflected frustration that the “fix” appeared to limit charging performance instead of fully resolving the overheating concerns.
Why Was the Lawsuit Dismissed?
The federal judge ultimately dismissed the lawsuit with prejudice, meaning the plaintiffs cannot refile the same claims in that court.
According to the ruling:
None of the plaintiffs alleged their vehicles actually caught fire
None alleged physical damage to their vehicles
Owners still retained Level 1 and Level 2 charging capability
The court found that loss of one charging method alone did not necessarily make the vehicles unfit for transportation
The judge also concluded the plaintiffs failed to adequately show the vehicles themselves were defective.
Importantly, the dismissal does not necessarily mean owners are satisfied with Nissan’s solution. It simply means the plaintiffs failed to state legally sufficient claims under the causes of action asserted in this particular federal case.
Canadian Lawsuit Still Moving Forward
Interestingly, while the California federal lawsuit has been dismissed, a separate proposed class action in Quebec, Canada was recently filed involving similar allegations.
That lawsuit alleges:
LEAF batteries can overheat and catch fire
Software updates are inadequate
Fast charging restrictions reduce vehicle utility
Nissan should replace defective batteries or repurchase vehicles
This means litigation over Nissan LEAF charging and battery concerns may continue in other jurisdictions despite the California dismissal.
Symptoms
Some Nissan LEAF owners have reported:
Warnings to avoid DC fast charging
Reduced charging speeds
Charging interruptions
Battery overheating concerns
Range anxiety caused by inability to use rapid charging
Reduced usefulness during long-distance travel
Even if no fire occurs, owners may still experience substantial inconvenience if the vehicle cannot use advertised fast charging functionality.
How to Proceed
Document Issues: Keep detailed records of all repairs, recall notices, charging warnings, dealership visits, and communications with Nissan. Make sure your concerns are specifically documented on repair orders.
Save Recall Correspondence: Retain all recall letters, software update notices, and charging restriction instructions you receive from Nissan.
Monitor Charging Performance: If your LEAF experiences charging interruptions, overheating warnings, or reduced charging speeds, document when and where it occurs.
