The General Motors Detroit-based automaker on Friday announced the voluntary recall of all 2019 and newer Chevrolet Bolts, extending its recall of the electric vehicle back to its first model year, 2017. It’s about a battery defect which could led to car fire. Experts “have identified the simultaneous presence of two rare manufacturing defects in the same battery cell.” GM urged drivers to limit their charging, avoid overnight charging and park them outside. GM is replacing the battery modules in those vehicles. Batteries with modules covered under the new recall will come with an 8-year/100,000-mile limited warranty (or 8-year/160,000 kilometers in Canada). The auto giant blamed supplier LG for two defects it described as “a torn anode tab and folded separator.” GM discovered manufacturing defects in certain battery cells produced at LG manufacturing facilities beyond the Ochang, Korea, plant. Both companies are working to rectify the cause of these defects. The latest recall will cost the company about $1 billion, bringing the total cost of the Bolt battery recalls to $1.8 billion.
The recall is an expansion of a similar action the company took last month when it discovered a defect in the battery that powers the EV. “All Chevrolet Bolt electric vehicles are now recalled due to the risk of the high-voltage battery pack catching fire,” the National Highway Traffic Safety Administration said in a statement. The Bolt’s global recall has also deepened consumer safety concerns about lithium-ion car batteries in general, which are used in virtually all electric vehicles and have impacted other car manufacturers.
