Li Auto has announced a recall of 11,411 units of its 2024 Li Mega electric MPV, citing a potential safety risk stemming from insufficient coolant corrosion protection. The recall, filed with China’s State Administration for Market Regulation (SAMR), is set to commence on November 7, 2025.

The affected vehicles were produced between February 18, 2024, and December 27, 2024. According to the recall notice (Recall No. S2025M0174V), the coolant in these vehicles may have inadequate anti-corrosion properties. Under specific conditions, this deficiency could lead to corrosion and leakage in the aluminium cooling plates of the power battery and front motor controller.

Such leakage could manifest as illuminated fault lights, restricted power, or the inability to power on the vehicle. In extreme scenarios, this defect poses a risk of thermal runaway in the power battery, presenting a significant safety hazard.

Li Auto will address the issue by providing free replacements of the coolant, power battery, and front motor controller for all recalled vehicles.

As an interim safety measure, Li Auto has implemented a cloud-based early warning system. This system is designed to detect potential coolant leakage and the associated battery safety risks. Upon detection, the company’s 400 customer service line and in-car Ecall system will contact affected users to arrange roadside assistance. Should a vehicle experience a fault, drivers will be alerted via in-car fault lights, text messages, and audible alarms, advising them to pull over safely and await rescue.

Li Auto assures owners that if they have not received any warnings or in-car fault messages, their vehicle is currently operating normally. Owners are encouraged to schedule the free replacement service at their earliest convenience once invited.

The direct cause of this recall is a Li Mega fire incident that occurred on October 23rd. While issuing the recall notice, Li Auto simultaneously published a statement on its official WeChat account, translated as follows:

On the evening of 23 October 2025, a fire involving a Li Mega 2024 model vehicle occurred in Shanghai, attracting significant attention from users, the media, and the public. We would like to extend our sincerest apologies to the vehicle owner and express our understanding of the concerns and worries of our users.

Immediately after the incident, we contacted the vehicle owner and actively cooperated with relevant departments in their investigation. As the accident vehicle requires joint inspection and testing by the user, fire department, and relevant agencies, this process must follow strict procedures and is time-consuming. As of now, no final technical conclusions have been reached.

In the meantime, we immediately launched an internal investigation and analysis, and reviewed the records from our cloud-based early warning system and specialised validation data. The results indicate that in the same batch of Li Mega 2024 model vehicles as the accident vehicle, due to insufficient anti-corrosion performance of the coolant in that batch, corrosion and leakage of the cooling aluminium plates for the power battery and front motor controller in the cooling circuit can occur under specific conditions. This can lead to the illumination of fault lights, restricted power, and the inability to power on the vehicle. In extreme cases, it could result in thermal runaway of the power battery, posing a safety hazard.

Safety is always Li Auto’s top priority. Upholding our principle of being highly responsible for user safety and having zero tolerance for potential hazards, we have proactively filed a recall plan with the State Administration for Market Regulation to conduct safety inspections and replacements/repairs for all Li Auto MEGA 2024 model vehicles from the affected batch. We will spare no effort to identify and eliminate every risk, ensuring all hazards are cleared and resolutely safeguarding the safety of every user’s vehicle.

Here are the answers to frequently asked questions from netizens:

01
The video shows only a few seconds between the discovery of the problem and the emergency escape. Is this accurate?

We deeply apologise for the distress and concern this incident has caused our users, and we have seriously reflected on the entire process. In fact, our cloud-based early warning system received relevant alerts approximately 4 hours before the vehicle caught fire, and staff contacted the owner and driver immediately. However, as there had been no prior instances of non-collision fires, we were unable to take emergency measures at the earliest opportunity, which led to missing the optimal time for early intervention.

This incident has served as a wake-up call for us and exposed shortcomings in our foresight and decisiveness when facing unprecedented, low-probability risk scenarios. Moving forward, we will:

• Strengthen training and support for our frontline teams, enhancing the risk identification and decision-making capabilities of both on-site and remote staff.
• Optimise our cloud-based early warning response strategy. Upon detecting critical signals, we will more decisively instruct drivers to pull over and arrange for emergency measures such as rescue.

We will use this incident as a crucial opportunity for improvement. Even for extremely low-probability safety hazards, we will take decisive action in advance to resolutely safeguard the safety of every user’s vehicle.

02
Was the battery explosion in this incident caused by a cell issue?

Based on the cloud-based early warning system records and specialised analytical validation, all cell status parameters were normal before this incident, ruling out fire caused by abnormal battery cells themselves.

This assessment has formed an internal technical conclusion, but the final result still requires confirmation by relevant national authorities after physical inspection of the accident vehicle, independent testing, and comprehensive analysis. We will continue to cooperate with the authoritative investigation.

03
After the accident, could the second-row electric sliding door be opened normally?

The low-voltage power supply for controlling door locks, window lifts, and other functions in the Li Auto MEGA is located in the central armrest area of the driver’s cabin. This position is designed to ensure that the vehicle maintains power in extreme situations such as collisions, supporting users in emergency operations like unlocking and opening doors.

After this accident, the entire vehicle automatically unlocked. Additionally, both the front and rear rows of Li Auto vehicles are equipped with mechanical emergency pull handles, which fully ensure that occupants can unlock and exit the vehicle in extreme circumstances.

04
How will similar accidents be avoided in the future?

Li Auto’s proactive filing of a recall plan with the State Administration for Market Regulation is precisely to prevent such accidents from happening again. Immediately after the incident, we launched an internal investigation and analysis. Based on cloud-based early warning system records and specialised validation data, we confirmed that the coolant in this batch of vehicles had insufficient anti-corrosion performance, potentially posing a safety hazard under specific conditions.

Upholding our principle of being highly responsible for user safety and having zero tolerance for potential hazards, we proactively filed a recall plan with the State Administration for Market Regulation. We will learn lessons from this accident, draw inferences, and strengthen the testing and validation of liquid chemical materials with more rigorous experiments to eliminate all hazards. We are committed to ensuring that no further spontaneous combustion incidents occur.

Furthermore, Li Auto’s proprietary Lianshan cloud-based early warning platform can provide 24/7 monitoring by combining vehicle and cloud data, using AI intelligent algorithms to identify potential quality and safety risks in advance. Our 400 customer service and in-car Ecall will contact users and arrange rescue services at the earliest opportunity to ensure your vehicle’s safety. Please use it with confidence.

05
Why is a proactive recall being initiated before the final accident investigation results are released?

We understand that users and the public are very concerned about the accident investigation conclusions and hope to receive definitive answers as soon as possible. Although the final technical investigation is still strictly underway, our principle is: if a risk is identified, we will never wait for a conclusion before taking action.

Based on cloud-based early warning system records and specialised validation data, we confirmed that the coolant in this batch of vehicles had insufficient anti-corrosion performance, potentially posing a safety hazard under specific conditions. Even if the probability of this scenario occurring is extremely low, we must eliminate the hazard to the highest standard. Upholding our principle of being highly responsible for user safety and having zero tolerance for risk, Li Auto has proactively filed a recall plan with the State Administration for Market Regulation to conduct safety inspections and replacements/repairs for all vehicles in this batch, sparing no effort to identify and eliminate every risk.

Editor’s comment

Just a week ago, a Li Mega in Shanghai suddenly caught fire while in motion, quickly becoming a hot topic of discussion. The vehicle uses CATL batteries, which have met China’s new national standard of “no fire, no explosion”. This standard has also been a major selling point in Li Auto’s marketing of its vehicles.

In the official statement released by Li Auto, it is claimed that “all cell status parameters were normal before this incident, ruling out fire caused by abnormal battery cells themselves.” (Section 2 above)
