The Chevy Bolt EV owner posted a photo (above) of his vehicle’s digital dash display in a Bolt EV owner’s group on Facebook this week, noting the predicted range on the vehicle had jumped up to 310 miles after he received a replacement battery as part of GM’s battery fire recall repair campaign. The owner said the display typically showed about 220 miles of predicted range, but after he received a replacement battery module, this figure climbed to 263 miles for the first time ever.
The replacement 65 kWh battery packs being installed in 2017 to 2019 Chevy Bolt EV models use newer battery chemistry that provides an eight percent boost in range over the early 60 kWh batteries used in these vehicles. This improved battery chemistry that was first implemented on the Bolt for the 2020 model year, along with the fact the battery is brand new, are likely behind the large increase in predicted range. As a reminder, the 2020 to 2022 model-year Chevy Bolt EV has an EPA-estimated range of 259 miles. The 2017 to 2019 model-year Bolt EV had an EPA-estimated range of 238 miles with the older 60 kWh battery.
In addition, the new battery packs being installed in Chevy Bolt EV vehicles will come with a new 8-year/100,000-mile limited parts warranty, protecting owners from future manufacturing defects.
The battery fire recall affects all Chevy Bolt EV and Bolt EUV models produced between 2017 and 2022 model years – believed to be around 140,000 units. Battery fires in these vehicles have been traced back to a manufacturing defect within the battery modules, which are produced by GM’s battery partner, LG Chem (now called LG Energy Solution). New replacement battery models have been improved to prevent future fires, with GM closely monitoring LG’s production processes.
Limited production of the Chevy Bolt EV and Bolt EUV returned on November 1st after it was paused due to the recall, but will go back offline starting on November 15th.
