Automakers are spending billions of {dollars} to transition to cleaner and greener battery-powered autos, however the brand new know-how has include an excellent steeper value: Status-damaging automobile fires, remembers, sudden energy loss and issues getting a few of the vehicles began.
The training curve with batteries is steep for conventional automakers, and battery know-how stays difficult even for Tesla, which has confronted comparable points. However automakers are desirous to embrace the brand new know-how with President Joe Biden within the White Home pushing for half of latest automobile gross sales to be electrical by 2030, a plan that may probably include billions of {dollars} in tax and different incentives.
Whereas pricey remembers happen in conventional autos with inside combustion engines, lots of the present hassle spots for electrical autos are software program and batteries — two areas essential to EVs that aren’t traditionally core areas of experience for Detroit automakers.
“Anytime you go into a brand new space of know-how, there’s extra to be realized than there may be that you already know,” Doug Betts, president of J.D. Energy’s automotive division, instructed CNBC. “There are dangers, and there are issues to be realized.”
The issues are already displaying up on company stability sheets. Three high-profile automaker remembers throughout the final yr — by Common Motors, Hyundai Motor and Ford Motor — involving about 132,500 electrical autos value a mixed $2.2 billion. Most not too long ago, GM mentioned it might spend $800 million on a recall of its Chevrolet Bolt EV following a number of reported fires on account of two “uncommon manufacturing defects” within the lithium-ion battery cells within the automobile’s battery pack.
Recollects are widespread within the automotive business, particularly for brand spanking new autos. It is one of many causes autos with the most recent applied sciences historically carry out poorly in some J.D. Energy research.
“Whenever you go from fuel to electrical, there’s going to be an entire new set of issues it’s a must to take care of, and we simply have to determine learn how to take care of these points that you already know that we have not needed to take care of up to now,” mentioned Guidehouse Insights principal analyst Sam Abuelsamid.
Latest remembers or issues with batteries or software program of latest EVs have included:
- GM final month issued a second recall of its 2017-2019 Chevrolet Bolt EVs after a minimum of two of the electrical autos that have been repaired for a earlier drawback erupted into flames. The automaker mentioned that officers with GM and LG Vitality Answer, which provides the automobile’s battery cells, recognized a second “uncommon manufacturing defect” within the EVs that will increase the chance of fireplace. The $800 million recall covers about 69,000 of the vehicles globally, together with almost 51,000 within the U.S.
- Porsche recalled the Taycan, its flagship EV, on account of a software program drawback that precipitated the automobile to fully lose energy whereas driving.
- In April, Ford Motor mentioned a “small quantity” of early prospects of its Mustang Mach-E crossover EV reported the 12-volt batteries of their autos would not cost, stopping these vehicles from working. Ford mentioned it was on account of a software program concern.
In Europe, Ford final yr recalled about 20,500 Kuga plug-in hybrid crossovers and suspended gross sales of the autos on account of considerations that the battery packs within the autos may probably overheat and trigger a automobile hearth. It value the automaker $400 million. - Hyundai Motor earlier this yr mentioned it might spend $900 million for a recall following fires in 15 of its Kona EVs.
- BMW, Volvo and others even have recalled EVs, together with plug-in hybrid fashions, on account of points with battery methods.
Betts, whose profession has included turns at Toyota, Fiat Chrysler and Apple, mentioned he believes legacy automakers will work out such issues as they launch extra electrical autos. He mentioned it is only a matter of time.
“I would not say that the normal OEMs [original equipment manufacturers] have had roughly hassle than Tesla,” he mentioned. “There have been fires with Teslas, too. Clearly, they’ve much more expertise now.”
Tesla
The National Highway Traffic Safety Administration opened an investigation in October 2019 into Tesla’s high-voltage batteries.
This Tesla Model S Plaid caught fire while the driver was at the wheel, according to a local fire department chief and attorneys representing the driver, on June 29, 2021, in Haverford, Pennsylvania

The probe began after NHTSA’s Office of Defects Investigation received a petition alleging that Tesla rolled out one or more software updates to control and conceal a potential defect that could result in non-crash fires in affected battery packs.
California-based attorney Edward Chen, who submitted the petition, also filed a class-action complaint for the issue against Tesla in August 2019. While Tesla recently agreed to pay $1.5 million to settle the lawsuit, NHTSA’s investigation remains open.
After the settlement, Tesla CEO Elon Musk said on Twitter: “If we are wrong, we are wrong. In this case, we were.”
Another proposed class-action lawsuit in California, Fish v. Tesla Inc., alleges that Tesla knowingly overstated the capacity of the high-voltage batteries in its cars and has used remote “battery health checks” and software updates to conceal battery degradation and deny owners battery replacements to which they were entitled under warranty.
The complaint says the lead plaintiff’s 2014 Tesla Model S lost more than half of its range over just six years, dropping to the equivalent of a 144-mile range on a full charge from a 265-mile range when he first bought it.
The battery complaints in the U.S. were similar to one in Norway in which more than 30 Tesla drivers told the courts that a 2019 software update slashed their Teslas’ battery life, decreased the range and lengthened the time the cars took to charge, according to Norwegian newspaper Nettavisen.
The courtroom preliminarily sided with the homeowners and instructed Tesla it could should pay prospects affected by the battery throttling software program as much as $16,000 every, which may quantity to a $163 million payout.
In April, Musk mentioned throughout an earnings name that there had been “extra challenges than anticipated” in growing new variations of the Tesla Mannequin S and X — the corporate’s dearer autos. That included the not too long ago launched Mannequin S Plaid and “fairly a little bit of growth to make sure that the battery of the brand new S/X is secure.”
Tesla didn’t reply to requests for touch upon the federal inquiries or allegations. The corporate shouldn’t be but delivering the up to date model of its luxurious SUV, the Mannequin X, and has delayed deliveries of many shoppers’ Mannequin S autos this yr.
Fires
Car fires are widespread, usually. In keeping with the National Fire Protection Association, there have been 212,500 automobile fires that precipitated 560 civilian deaths, 1,500 civilian accidents and $1.9 billion in direct property harm within the U.S. in 2018.
Most of these fires didn’t contain EVs, which nonetheless solely make up about 2% to three% of latest automobile gross sales within the U.S. yearly. Nonetheless, automakers and their battery cell suppliers are going to should be extraordinarily cautious within the manufacturing of battery-electric autos and their elements.
“The manufacturing processes are actually going to should be tightened up,” Abuelsamid mentioned. “It is a part of coping with the way in which batteries behave. They do not like warmth, they usually do not like contamination. They’re very delicate.”
One thing as small as an errant spark from welding or one other course of could cause a significant issue in battery cells.
Specialists are nonetheless attempting to find out EV hearth incident charges; the info is difficult to gather from disparate hearth departments. Fleet Auto Information reported that 2019 London Fireplace Brigade data counsel, based mostly on a small native sampling, “an incident charge of 0.04% for petrol and diesel automobile fires, whereas the speed for plug-in automobile is greater than double at 0.1%.”
