General Motors has notified some owners of the 2017 Chevrolet Bolt electric car, since there is a possible issue with the Bolt’s lithium-ion battery pack, which could cause it to fail. The problem is with a malfunction in one or more of the 288 battery cells, that could deliver incorrect data to the battery management system.
GM says of the more than 10,000 Bolt EVs sold, fewer than 1 percent of the cars produced could have the problem. Early production Bolt electric cars are more likely to have the issue as well.
The battery issue was originally revealed on Plug-In Cars, where Brad Berman discussed how he experienced the issue in June with his 2017 Chevy Bolt. On his way home one day, the battery indicated that it had 100 miles left of range, but then moments later the Bolt came to an abrupt halt with only 9 miles showing on the indicator.
Normally the Chevy Bolt will enter a “turtle mode” to reduce the power output when the battery capacity is low, but that did not happen here. The Bolt also wouldn’t shift into drive or reverse, but it did power up.
“The car could be powered up but not shifted into Drive or Reverse. After multiple failed attempts to shift into Drive after restarting the car, I shifted into Neutral and rolled down a slight incline to reposition the car more safely on the side of the road.”
