GM recalls Bolt EVs again because some batteries may pose fire risk

General Motors is recalling tens of thousands of Chevrolet all-electric Bolt hatchbacks for the second time in less than a year because of a potential fire risk. 

The company made the move on Friday after two Bolts caught fire without impact recently. GM is confirming that at least one of the Bolt fires was battery-related and happened despite the owner getting the fix from the first recall.

This time, GM said it would recall all 2017-19 model-year Bolts. In total, the recall involves 68,000 vehicles globally; of those, 50,925 are in the United States. The vehicles contain high-voltage batteries produced at LG Chem’s Ochang, South Korea, facility. 

The 2017 Chevrolet Bolt EV, which is made at the Orion Assembly in Orion Township, in September 2016. This model year is part of GM's second recall of Chevrolet Bolt EVs due to potential fire risk.

“As part of GM’s commitment to safety, experts from GM and LG have identified the simultaneous presence of two rare manufacturing defects in the same battery cell as the root cause of battery fires in certain Chevrolet Bolt EVs,” GM spokesman Dan Flores said in a statement. “As part of this recall, GM will replace defective battery modules in the recall population. We will notify customers when replacement parts are ready.” 

Until GM can get parts to dealers and people can get their vehicles in for the fix, owners of the recalled cars should not park them in garages.

Also, Flores said GM recommends they do the following:

  • Return the vehicle to the 90% state of charge limitation using Hilltop Reserve mode (for 2017-18 model years) or Target Charge Level mode (for 2019 model year), or visit a dealer to make that change.
  • Charge the vehicle after each use and avoid depleting the battery below 70 miles of remaining range.  
  • Park the vehicle outside immediately after charging and do not leave the vehicle charging overnight.
  • Customers who have not received the advanced diagnostics software should visit their dealer to get the update. After obtaining the software, limit the state of charge to 90% and follow the advice above.

The starting price for a 2021 base Chevrolet Bolt EV is $36,500. Flores said GM is not providing an estimate at this time for how much this recall and the first one will cost the automaker. Flores did say that since the first recall repair, including the advanced software diagnostics, the cost to GM “was not material” but GM did not disclose a cost for it.
