LG is cooperating and providing GM the data it requests, Flores said, noting LG is as eager as GM to fix the problem.
“It’s in everybody’s best interest if we speed the repairs along as best as we can,” Flores said. “Both LG and GM understand the significance in what we’re doing here and we’re committed to doing the right thing for our customers.”
GM and LG know the defects are a torn anode tab and a folded separator in the modules. The presence of those two defects in the same battery cell increases the risk of a fire, Flores said. But GM and LG do not know what is causing those defects in the manufacturing process. They also do not know if the defects are in every Bolt that is recalled, or just a few.
GM is also working to develop a software technology that will enable a dealership’s service technician to identify whether a specific module is defective and just replace that defective module, Flores said.
“But short of that, we’re going to replace all the five modules in all the vehicles,” Flores said.
That’s once GM is assured that LG Chem is making the new modules without any defects. Then, and only then, will GM contact all the Bolt owners to let them know a remedy is available and dealerships will start repairs, Flores said.
Flores could not provide a specific timeline on how long Bolt owners might have to wait for a repair at a dealership. But, he said, besides searching for the cause of the defect, GM has assigned a team to work with LG’s production team on increasing, “their capability to build battery packs because we’re going to need a lot and it will take time to build up inventory, to build it, ship it and build product for Orion.”
