Movies of burning Teslas greater than a decade in the past could have been the one largest issue within the anti-EV attitudes of thousands and thousands of individuals. They had been damned scary, and even these of us who had been staunch advocates of the EV revolution had been shocked by how violent they had been. Blaring headlines screamed about first responders getting crash programs in the right way to extinguish battery fires. HOAs all throughout the US voted to ban electrical automobiles from their properties.

The Washington Submit reported this week that there are at the moment 3.2 million automobiles within the US which have been tagged with a “park outdoors” security warning, in response to an evaluation by CarFax. The overwhelming majority of them are not electrical automobiles. In truth, the hazard typically comes from “at all times on” electronics that keep lively even when the car is parked.

We’d by no means counsel {that a} automotive fireplace shouldn’t be a critical problem, however battery fires affected solely a couple of dozen first-generation Chevy Bolts and the fallout price GM and LG Chem over $1 billion. How is it that most people doesn’t know the homeowners of greater than 3 million automobiles — most of them with gasoline or diesel engines — are at the moment being informed to park their automobiles outdoors away from their houses due to the danger of spontaneous fires whereas parked?

Typical Vehicles Have A Larger Fireplace Danger Than EVs

The Washington Submit analyzed NHTSA recall notices and located that typical fuel and diesel automobiles made up the overwhelming majority of automobiles lined by the “park outdoors” label since 2021. The variety of these remembers has surged in recent times. Federal authorities have introduced 17 new “park outdoors” remembers within the first seven months of 2026, protecting a complete of 1.7 million automobiles and making 2026 the second-highest variety of automobiles since one of these recall started greater than a decade in the past.

The explanation for many of these remembers shouldn’t be what you assume. “It’s a mixture of issues inflicting this,” mentioned Sean Kane, president of Security Analysis and Methods, which focuses on auto security evaluation. “It’s messy. It doesn’t lend itself to easy description of what’s occurring. However it boils all the way down to rising digital methods and the variety of parts.”

Gasoline and diesel automobiles nonetheless account for the overwhelming majority of automobiles lined by “park outdoors” remembers, in response to NHTSA information. Partially, that displays how fuel and diesel nonetheless dominate the US market. About 94 p.c of light-duty automobiles have typical inside combustion engines, whereas about 6 p.c are hybrids and absolutely electrical.

“They’re often called ‘key-off’ fires,” Frank Borris, a former NHTSA investigator who now works as a security advisor, informed the Washington Submit. “The engine is off,” he mentioned, “however the circuits are nonetheless scorching they usually keep scorching on a regular basis.” Scorching on this case means they’re powered on, not that they’re overheating. That half comes later.

Earlier this yr, Kia wanted to recall 463,000 Tellurides due to the danger that the entrance energy seat swap may overheat and ignite the seat. It was the second time Kia had issued a recall for that one defect. The primary recall two years in the past didn’t absolutely tackle the issue. Greater than 66,000 Ford Expeditions and Lincoln Navigators from the 2021 mannequin yr have been recalled due to circuit boards within the battery junction field that would quick out. At the very least 16 fires had been blamed on the issue, which regularly ignited when the automobiles had been parked and turned off.

NHTSA Creates “Park Exterior” Designation

The Nationwide Freeway Site visitors Security Administration (NHTSA) created the “park outdoors” designation in 2015 to flag defects that may ignite a car even when it’s shut down and parked. For years it was uncommon, with producers averaging about one such recall a yr from 2015 via 2019. Since then, the variety of such warnings has elevated dramatically. NHTSA logged 10 “park outdoors” remembers in 2024. Within the first seven months of 2026 there have been 17, with eight of these introduced in June and July.

NHTSA has issued 93 “park outdoors” remembers since 2021, in response to a Submit evaluation. Practically half of them — 44 in all — utilized to automobiles solely with typical internal-combustion engines, whereas 38 remembers had been only for EVs or hybrids. So the variety of campaigns had been practically equally divided between fuel and electrical or hybrid automobiles. However fuel automobiles draw back when evaluating the scale of the remembers.

Gasoline-only campaigns lined a mixed 4.6 million automobiles with “park outdoors” remembers over the previous 5 years, in comparison with solely about 662,000 automobiles that had been EVs or hybrids. The most important variety of recalled automobiles had “blended powertrains” — that means the remembers included fashions with typical engines in addition to EVs and hybrids. However fuel and diesel automobiles additionally dominated the “blended” powertrain class.

NHTSA introduced two remembers in September 2023 which accounted for about two thirds of the 5.1 million automobiles with “blended powertrains” being recalled. That’s when Hyundai recalled practically 1.65 million automobiles and Kia recalled greater than 1.73 million automobiles “because of the danger of fireplace.” The automakers mentioned “the most secure place to park [the vehicle] is outdoors and away from houses and different constructions. Fires can happen whether or not the car is parked and turned off or whereas driving.”

Hyundai’s recall lined greater than a dozen fashions, largely with fuel engines and fewer than 100,000 hybrid and gasoline cell variations. Gasoline engines made up nearly the entire dozen Kia fashions recalled. The Hyundai and Kia automobiles shared the identical defect — the anti-lock brake system may leak brake fluid and trigger {an electrical} quick, triggering an engine fireplace even when the automotive was parked. “They’ve found out extra methods to catch fireplace than some other car,” Kane mentioned.

Higher Knowledge

Little is thought concerning the relative fireplace danger in EVs in comparison with fuel automobiles — at the least in america. Regulators sometimes haven’t collected information on car fires by powertrain. That’s starting to alter, mentioned Adam Barowy, principal analysis engineer for the Fireplace Security Analysis Institute. Beginning this yr, fireplace companies nationwide switched to a brand new federal reporting system that features details about car powertrains that ought to make extra granular information out there. “Proper now there’s fairly restricted information on whether or not they’re extra more likely to catch fireplace — at the least for North American automobiles,” Barowy mentioned.

Different nations have offered restricted appears to be like on the EV fireplace points. Knowledge from Norway, the place automobiles with plugs are actually greater than 97 p.c of the brand new automotive market, confirmed that fuel and diesel automobiles had a fireplace incidence charge that was 4 instances greater than EVs from 2016 to 2021.

Yahoo says what everyone knows to be true. It’s tempting to imagine all EVs are a fireplace danger, however the reality is kind of totally different. Immediately, the danger shouldn’t be a lot from batteries. It’s from seat motors, energy steering wiring, starter relays, and “at all times on” management modules that keep energized lengthy after a car is parked and the motive force has walked away. In June, Stellantis recalled Wrangler and Gladiator fashions due to a fireplace danger that was traced to an influence steering pump connection.

Concern Of Fireplace

The worry of EV fires is tough to beat. A couple of years in the past, catastrophic fires inside two packed parking garages caught the eye of fireplace researchers. One was on New 12 months’s Eve 2017, when 1,400 automobiles burned in a storage at an enviornment in Liverpool, England. In 2020, a fireplace broken tons of of automobiles at Norway’s Stavanger airport. Investigators puzzled what made these fires such disasters, and the primary thought anybody had was that an electrical automotive was guilty.

Later, it was decided the fireplace in Liverpool began in an previous Land Rover and the blaze in Norway was brought on by a diesel powered Opel. A contributing issue within the Norway blaze was that the storage the place the Opel was parked didn’t have sufficient overhead clearance for fireplace vans to enter.

A Car Fireplace Each Three Minutes

Fires are scary, however coincidence shouldn’t be causation. In line with the Nationwide Fireplace Prevention Affiliation, there are greater than 170,000 car fires yearly within the US — about one each 3 minutes. Mixed, they account for “extra deaths than nonresidential construction fires and residential condominium fires. Solely construction fireplace incidents in a single and two household houses had greater loss of life charges per fireplace than car fires.” They’re so widespread that the mainstream press barely mentions them. However let an EV catch fireplace and it’s all fingers on deck!

Automobiles powered by inside combustion engines expertise roughly 1,500 fires per 100,000 automobiles bought, making them considerably extra widespread than electrical car fires, which common about 25 per 100,000 bought. Meaning EVs are considerably much less more likely to catch fireplace than typical automobiles with infernal combustion engines. Many could discover that statistic stunning, however it’s true. The trusty fuel automotive in your storage is much extra more likely to catch fireplace than an EV!

I discussed in a remark just lately that my spouse is continually telling me I can’t simply complain about one thing. I’ve to have options prepared to deal with my considerations. (She is ceaselessly disenchanted.) My guess is that the general public we encounter every day imagine of their coronary heart of hearts that EVs are an excessive fireplace danger. However now you’ve gotten the knowledge at your fingertips to counter these fears with information. Data is energy. Use it properly!
