General Motors is recalling roughly 68,700 Bolt EVs to temporarily limit their battery capacities hoping it'll prevent further battery fires. The automaker has confirmed five fires are the result of a defect inside the EV's high-voltage battery systems. The batteries contain cells from LG Chem and as they approach a 100% charged state there's an issue that can cause a short-circuit and spark a flame.
The issue has been under investigation by the safety regulators since last month.
Recommendations for owners ∞
On the surface, 5-out-of-68,700 vehicles sounds like pretty good odds but the situation is too serious to take any chances. GM is asking owners to:
- Manually limit their battery capacities to 90% through multiple options available through the car's infotainment system.
- Not park in or around any enclosed structures, particularily if the vehicle is charging or has a 100% charge.
- Bring their cars in to receive a software update on or around November 17th to reduce their battery capacity.
Obviously a 90% battery capacity is not ideal as it limits the car's range but GM emphasizes this is only a temporary solution until they can get to the root of the problem and provide a more permanent solution sometime in 2021.
