General Motors recently issued a voluntary expansion to an existing battery module recall for the Chevy Bolt EV, including all models and model years, as well as the recently released Chevy Bolt EUV. As a result, some early Chevy Bolt EV owners may be in store for a range boost with the new replacement battery modules.
To recap, General Motors initially issued a battery recall for the Chevy Bolt EV in November of 2020, later expanding the recall in July of 2021. The recall was issued to address a defect with the vehicle battery packs, which is believed to be the cause of 10 vehicle fires. GM later expanded the recall again in August, including all remaining 2019 model-year vehicles, as well as all 2020 through 2022 model-year vehicles, and the Chevy Bolt EUV.
The fire risk was tracked down to two manufacturing defects from the battery supplier, LG Chem, including a torn anode tab and folded separator. The recall is expected to cost upwards of $1.8 billion.
Chevy Bolt EV customers and Chevy Bolt EUV customers will receive new battery modules free of charge. Now, according to Green Car Reports, which cites an official GM communication to some owners, the new replacement lithium-ion battery modules offer “GM’s most advanced Bolt chemistry,” and will include an additional 8 percent battery capacity, providing extended vehicle range compared to the older battery packs.
In addition, the new battery packs will include a new 8-year/100,000-mile limited parts warranty for U.S. vehicles, and an 8-year/160,000-km limited warranty for vehicles in Canada.
General Motors increased the range rating for the Bolt EV with the 2020 model year, offering a rating of 259 miles, up from the previous range of 238 miles. The official battery capacity was increased to 65 kWh, up from the previous 60 kWh.
