GM Replacing Battery Modules On Recalled Chevy Bolts

The Chevrolet Bolt has become the focus of negative attention following some fire incidents that were believed to be related to battery components. After two recalls, General Motors has decided to replace the battery modules of every model that could be impacted — rather than focusing on units with proven defects.

While it’s undoubtedly going to cost the company a fortune, this is probably the correct move. The implications of negative publicity stemming from repeat vehicle fires have a tendency to linger and be blown up to larger-than-life proportions. This is especially true if an automaker rushed that vehicle to market to better wrangle the segment. Just ask Ford about the Pinto if you’ve any doubts.

GM’s previous solution involved simply updating the software of all 2017-2019 model year Bolt EVs. However, one of those vehicles also caught fire and forced the automaker to double down on its recommendations to have Chevy customers park their cars outdoors a healthy distance from anything they might not want to see barbequed. Charging protocols were also issued, with owners being warned not to fully deplete the battery.

It also threw its supplier under the bus, citing South Korean manufacturer LG Chem’s Ochang facility in South Korea as having issued bunk hardware. Though LG has received additional criticism from other automakers who’ve used its batteries only to find themselves issuing fire-related recalls of their own (e.g. Hyundai).

The supplier has said it’s onboard to help General Motors to ensure recall efforts are carried swiftly and that the duo had jointly identified two manufacturing defects (claimed to be rare) that caused the fires. Those modules will no be replaced, without the need for the automaker to conduct an investigation of every vehicle. Customers can bring their vehicles to any GM service center for repairs, though it will need to be EV-certified to handle this particular recall.

In the meantime, it’s still recommending owners park their Bolts outdoors and charge them after each use to avoid having to keep them plugged in for longer than absolutely necessary. Ideally, the manufacturer doesn’t even want you to leave them unattended while charging. The software update is also supposed to be helpful, though it doesn’t seem to have been an effective remedy overall.

    Fortunately, GM does not sell a lot of these. As this happens Tesla pulls further ahead. With the exception of the Corvette and a few Cadillac sedans does GM produce anything that is desirable.

    Subjective of course, but GM seems to be the poster child for recalls these days.

  • 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.

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.
  • Duke Woolworth Weight 4800# as I recall.
  • Kwik_Shift_Pro4X '19 Nissan Frontier @78000 miles has been oil changes ( eng/ diffs/ tranny/ transfer). Still on original brakes and second set of tires.
