GM finds another fire risk in ‘fixed’ Chevrolet bolts

The next generation Chevrolet Bolt is almost here, but General Motors can’t seem to escape the shadow of the model’s troubled past. The automaker just recalled old Bolts again, a reminder that the troubles with its early electric vehicle experiments are far from over.

You’ll no doubt remember that three years ago, General Motors recalled more than 140,000 Bolts in the United States because they posed a risk of catching fire. The issue can be traced to an issue with the battery pack, which comes from LG. Now, General Motors has revealed that some 2020-2022 Bolt EV and Bolt EUV models that were fixed in previous recalls still pose a risk of catching fire.

As part of previous recalls, GM dealers were required to install advanced diagnostic software that alerted drivers to faults within the batteries. However, it has been revealed that in some Bolts, the software is not installed correctly and the vehicle may not recognize a defective battery module that needs to be replaced. GM says this increases the risk of vehicle fires.

That’s bad news for General Motors, which is already deeply embarrassed by previous Bolt problems. Fortunately, the latest glitch isn’t widespread, affecting only 107 vehicles in the United States. This includes 2020-2022 Bolt EV models produced from November 8, 2019 to May 19, 2021, and 2022 Bolt EUV models produced from March 30, 2021 to July 23, 2021.

The automaker became aware of the issue on July 23, 2024, after the brand’s quality manager discovered that a faulty software update limited the state of charge of a customer’s Bolt EUV to 80%, despite exceeding the stated range of approximately 6,200 miles (about 10,000 kilometers). ) evaluation period.

GM will notify owners by December 16, 2024 and instruct them to take their electric vehicles to dealers where the diagnostic software will be properly installed. During this time, GM is asking owners to set a 90% charging limit on their vehicles to encourage them to charge more frequently and avoid draining the battery below 70 miles (113 kilometers) of remaining range. In addition, car owners should park their vehicles outdoors immediately after charging and do not let their vehicles charge indoors overnight.
