How many hybrids have caught fire?

[VanWalker]

Hybrid and plug-in hybrid vehicles have an exceptionally low reported fire rate of 0.04 per 1,000 vehicles, significantly lower than internal combustion engine (ICE) vehicles. Analysis of U.S. vehicle fire incident data from 2020 to 2025 shows hybrids and plug-in hybrids accounted for a minimal fraction of total incidents, confirming their high safety standard relative to fire risk.

The core data is clear. Over the six-year period from 2020 to 2025, a total of 51,142 vehicle fires were reported. The breakdown by powertrain is stark:

• ICE Vehicles: 50,833 fires, representing 99.39% of all incidents.
• Hybrids & Plug-in Hybrids: 222 fires, representing 0.43% of all incidents.
• Battery Electric Vehicles (EVs): 87 fires, representing 0.17% of all incidents.

When normalized for exposure, the fire rate per 1,000 vehicles is most telling. The rate for hybrids and plug-in hybrids is 0.04. This figure is derived from the number of fires relative to their population on the road. In practical terms, this means you are vastly more likely to encounter a fire in a traditional gasoline or diesel vehicle. Industry data consistently shows that the most significant fire risks in vehicles are associated with conventional fuel systems and aging electrical wiring in ICE cars, not with high-voltage hybrid or electric powertrains.

The safety of hybrid systems is underpinned by rigorous design. High-voltage battery packs are equipped with sophisticated cooling systems and battery management software that continuously monitors cell voltage and temperature. These systems are designed to isolate faults before they can escalate. Furthermore, automatic high-voltage disconnects in the event of a collision are standard, cutting power to reduce risk.

It's important to contextualize these numbers. The 222 fires involving hybrids occurred over six years across millions of vehicles in operation. Many of these incidents may not have originated from the hybrid battery system itself but could be due to shared conventional components (like 12V batteries or wiring) or external causes (such as arson or accidents). The data reflects all reported fires where the vehicle was identified as a hybrid, not necessarily fires caused by its hybrid powertrain.

For prospective buyers concerned about safety, this data is compelling. The statistical risk of a hybrid vehicle catching fire is extremely low. This record is a result of decades of engineering refinement and stringent safety testing mandated globally. When considering overall vehicle safety, fire risk should not be a deterrent against choosing a hybrid or plug-in hybrid model.

As a data analyst who tracks automotive safety trends, I look at these numbers and see a very clear story. The fear around hybrid vehicle fires isn't backed by the statistics. With only 222 fire incidents attributed to hybrids over six years—amidst tens of thousands of gasoline car fires—the relative risk is minuscule.

That 0.04 fires per 1,000 vehicles rate is a key performance indicator. It tells me that the engineering controls in place are highly effective. My takeaway for consumers is straightforward: if you're comparing vehicles based on fire safety, a modern hybrid is a statistically safer bet than a conventional car. The data from recent years gives us a solid, real-world basis for that conclusion.

I’ll be honest, I was a bit nervous about the battery in my plug-in hybrid when I first bought it. You hear stories. But then I looked into it. Seeing that hybrids and electrics together made up less than 1% of all car fires over several years was a real eye-opener. My old gasoline SUV felt more worrisome in hindsight.

My mechanic explained it to me simply. He said the high-voltage systems in these cars have more safeguards than the regular 12-volt system in any car. They’re built to shut down if anything seems off. The numbers prove it—0.04 fires per thousand is a tiny, tiny chance. It actually made me feel better about my new car than my old one. The risk is just elsewhere.

From an engineering perspective, the low fire incidence in hybrids is a validation of system design. The primary focus is on thermal management and containment. Lithium-ion battery packs are not inert; they contain significant energy. However, they are housed in sealed enclosures with liquid cooling or sophisticated air channels to maintain optimal temperature.

More critically, the Battery Management System (BMS) is the guardian. It monitors each cell module for voltage irregularity and temperature spikes. If an anomaly is detected, the system can limit power output or command a full shutdown. In a collision, inertial sensors trigger pyrotechnic disconnects to physically separate the high-voltage battery from the rest of the vehicle's circuitry within milliseconds.

This multi-layered safety architecture—physical, electronic, and software-based—is why the real-world failure rate leading to fire is so exceptionally low. The 0.43% incident share, largely from non-battery sources, aligns with the expected reliability of such a redundant system.

Let’s talk about what this data means in the bigger picture. Yes, any vehicle fire is serious, but focusing solely on hybrids or EVs misses the point. The overwhelming majority of fire risk—over 99%—still resides with the hundreds of millions of gasoline and diesel cars on the road. Their fuel is highly flammable, and their electrical systems can degrade over time.

The conversation needs to shift from "can a hybrid battery catch fire?" to "what is my actual risk?" The answer, supported by half a decade of reports, is that your risk is orders of magnitude lower. Automotive safety regulators scrutinize these powertrains intensely. The fact that hybrids have maintained such a low incident rate while their sales have grown proves the technology is mature and safe.

When new technology enters the market, it's scrutinized under a microscope, while long-established risks become normalized. This data helps cut through that imbalance. It provides a factual foundation for assessing true risk, which strongly favors newer electrified powertrains from a fire safety perspective.
