NHTSA Launching Investigation Into Chevy Bolt Fires

According to the very people trying to sell them, electric vehicles are slated to become the hottest commodity on the automotive market since the Ford Pinto, Pontiac Fiero, or Ferrari 458 Italia. But, following a swath of highly publicized fires, there’s been this creeping narrative that there may be some unaddressed safety concerns pertaining to EVs. Numerous video clips of vehicles spontaneously combusting in Asia and local media reports of phantom garage fires in North America have helped feed the story, with regulators now taking accusations of battery flambé extremely seriously.

Case in point is the National Highway Traffic Safety Administration’s new investigation into the Chevrolet Bolt. The agency’s Office of Defects Investigation received just two complaints regarding 2018 and 2019 Bolts that were alleged to have caught fire in a similar manner. But lids were flipped when the NHTSA realized it had seen a 2017 model with a similar burn pattern working its way up through the rear seat. The group is now launching a preliminary evaluation to decide whether these were freak accidents or if the Chevy Bolt actually has a tendency to catch fire while nobody is around.

Since the mere suggestion of a specific model having safety issues is often all it takes to cement it into vehicular lore, we want to be extremely clear in saying there’s little proof of anything at this juncture. A handful of Bolts have caught fire under suspiciously similar circumstances and the NHTSA wants to make sure that it doesn’t pertain to the other 77,842 examples manufactured between 2017 and 2020.

It might also be nice for regulators to nip any EV fire hazards in the bud before they become the dominant form of personal conveyance. While reports of battery fires routinely get more media attention than the banged-up Buick Century I saw burning on the Henry Hudson Parkway over the weekend, there’s not supposed to be much of a difference in the frequency of gasoline and battery-related car fires. But regulators seem terrified that won’t remain true as more battery-driven vehicles enter the marketplace. Automakers are no less concerned because absolutely nobody wants to be the brand with the famously dangerous EVs.

General Motors informed us that it was aware of the preliminary examination and intended on cooperating with the investigation fully, as well as launching its own to make doubly sure there’s no doubt about what is/isn’t happening with the Bolt.

Automotive News, which first caught wind of investigation PE 20-016, said the NHTSA reported that “the fire damage appeared to be concentrated in the EV battery compartment area with penetration into the passenger compartment from under the rear seat,” but that nothing conclusive had been determined at this juncture.

From AN:

U.S. safety regulators will evaluate the cause of the fires as well as the scope, frequency and consequence of the alleged defect.

Most NHTSA investigations start as preliminary evaluations, where agency engineers request information from the manufacturer, including data on complaints, injuries and warranty claims. The manufacturer can also present its view regarding the alleged defect and may issue a recall.

After the evaluation, NHTSA will either close the investigation or move into the next phase. If a safety-related defect exists, according to NHTSA, the agency may send a “recall request” letter to the manufacturer.

A lot of the concerns pertain to the unique dangers of battery fires — something we recently covered following a report from the National Transportation Safety Board (NTSB) claiming most U.S. fire departments couldn’t handle them. The NTSB has been cracking down on newer automotive technologies in general but has recently focused on electric vehicle fires as manufacturers gear up to dump countless new models into various markets over the next few years.

    The following documentary clip rather vividly demonstrates a very typical real-world scenario which results when self-driving technology is combined with internal combustion/liquid fuels. Note: Language advisory (and other unpleasantness). https://tinyurl.com/y33jqxlx

    It is tragic GM is betting the company on a lost cause like the Bolt.

      @28-Cars-Later Wild prediction: Tesla will buy GMNA in a multi year transition deal when the parent GM pulls out of North America. This will be for its EV technologies and distribution network. Tesla will sell cheaper crappier EVs under another marque and use the GMNA dealer network to move the volume.

  • Lou_BC I had a 2010 Ford F150 and 2010 Toyota Sienna. The F150 went through 3 sets of brakes and Sienna 2 sets. Similar mileage and 10 year span.4 sets tires on F150. Truck needed a set of rear shocks and front axle seals. The solenoid in the T-case was replaced under warranty. I replaced a "blend door motor" on heater. Sienna needed a water pump and heater blower both on warranty. One TSB then recall on spare tire cable. Has a limp mode due to an engine sensor failure. At 11 years old I had to replace clutch pack in rear diff F150. My ZR2 diesel at 55,000 km. Needs new tires. Duratrac's worn and chewed up. Needed front end alignment (1st time ever on any truck I've owned).Rear brakes worn out. Left pads were to metal. Chevy rear brakes don't like offroad. Weird "inside out" dents in a few spots rear fenders. Typically GM can't really build an offroad truck issue. They won't warranty. Has fender-well liners. Tore off one rear shock protector. Was cheaper to order from GM warehouse through parts supplier than through Chevy dealer. Lots of squeaks and rattles. Infotainment has crashed a few times. Seat heater modual was on recall. One of those post sale retrofit.Local dealer is horrific. If my son can't service or repair it, I'll drive 120 km to the next town. 1st and last Chevy. Love the drivetrain and suspension. Fit and finish mediocre. Dealer sucks.
  • MaintenanceCosts You expect everything on Amazon and eBay to be fake, but it's a shame to see fake stuff on Summit Racing. Glad they pulled it.
  • SCE to AUX 08 Rabbit (college car, 128k miles): Everything is expensive and difficult to repair. Bought it several years ago as a favor to a friend leaving the country. I outsourced the clutch ($1200), but I did all other work. Ignition switch, all calipers, pads, rotors, A/C compressor, blower fan, cooling fan, plugs and coils, belts and tensioners, 3 flat tires (nails), and on and on.19 Ioniq EV (66k miles): 12V battery, wipers, 1 set of tires, cabin air filter, new pads and rotors at 15k miles since the factory ones wore funny, 1 qt of reduction gear oil. Insurance is cheap. It costs me nearly nothing to drive it.22 Santa Fe (22k miles): Nothing yet, except oil changes. I dread having to buy tires.
  • AZFelix 2015 Sonata Limited72k when purchased, 176k miles currentlyI perform all maintenance and repairs except for alignment, tire mounting, tire patching, and glass work (tint and passenger left due to rock hit). Most parts purchased through rockauto.com.Maintenance and repairs during three years of ownership:Front rotors and all brake pads upgraded shortly after purchase.Preparing for 17th oil change (full synthetic plus filter c.$50), one PCV valve.Timing & accessory belts, belt tensioner.Coolant full flush and change.Fibrous plastic material engine under tray replaced by aftermarket solid plastic piece $110.One set of tires (c.$500 +installation) plus two replacements and a number of patches due to nails, etc. Second set coming soon.Hood struts $30.Front struts, rear shocks, plus sway bar links, front ball joints, tie rod ends, right CV axle (large rock on freeway damaged it and I took the opportunity to redo the rest of items on this list).Battery c.$260.Two sets of spark plugs @ $50/set.Three sets of cabin and engine filters.Valve cover gasket (next week).Averages out to c.$1400 per year for the past three years. Minor driver seat bolster wear, front rock chips, and assorted dents & dings but otherwise looks and drives very well.
  • 3-On-The-Tree 2014 Ford F150 Ecoboost 3.5L. By 80,000mi I had to have the rear main oil seal replaced twice. Driver side turbo leaking had to have all hoses replaced. Passenger side turbo had to be completely replaced. Engine timing chain front cover leak had to be replaced. Transmission front pump leak had to be removed and replaced. Ford renewed my faith in Extended warranty’s because luckily I had one and used it to the fullest. Sold that truck on caravan and got me a 2021 Tundra Crewmax 4x4. Not a fan of turbos and I will never own a Ford again much less cars with turbos to include newer Toyotas. And I’m a Toyota guy.
