General Motors is recalling some older Chevrolet Bolts for a second time to fix persistent battery problems that can set the electric cars ablaze. Until repairs are done, GM says owners should park the cars outdoors, limit charging to 90% of battery capacity, and not deplete batteries below 70 miles of range. The company says the Bolts should not be charged overnight, and should be parked outside immediately after they are charged, per the AP. The second recall comes after two Bolts that had been fixed under a previous recall caught fire, one in Vermont and the other in New Jersey. It covers about 69,000 Bolts worldwide from 2017, 2018 and part of the 2019 model year. All have batteries made by LG Chem in South Korea.
GM says it has confirmed battery fires in nine Bolts. NHTSA said two people suffered smoke inhalation and the battery fire spread to one house. In a statement Friday the company said the faulty Bolt batteries can have two rare manufacturing defects in the same cell at the same time. So GM will now replace any defective battery modules and possibly the whole battery pack. Spokesman Dan Flores says engineers are still working around the clock on how to find the battery defect and what the repairs will be. He said GM doesn’t know how long it will take to develop the fix. The number of Bolts with the defect is likely to be small, Flores said. The previous recall announced in April didn't fully fix the problem. It was diagnostic software designed to look for battery anomalies. If one was found, GM said it would replace faulty parts.
