The recall and others raise questions about lithium-ion batteries, which are now used in almost all electric vehicles. Ford, BMW and Hyundai have all recalled batteries recently. President Joe Biden will need achieve a goal of halving greenhouse gas emissions by 2030 as part of a broader effort to fight climate change.
GM’s recall announced Friday adds approximately 73,000 bolts from the 2019 through 2022 model years to a previous recall of 69,000 older bolts. GM has said that in rare cases, batteries have two manufacturing defects that can cause fires.
The Detroit-based automaker has said it will replace battery modules in all vehicles. In older versions, all five modules will be replaced.
The latest recall will cost the company around $ 1 billion, bringing the total cost of Bolt battery recalls to $ 1.8 billion.
GM said owners should limit charging to 90% of the battery’s capacity. The Bolts, including a new SUV, are also expected to be parked outside until the modules are replaced.
The initial recall was attributed to a manufacturing defect at a South Korean plant run by LG Chemical Solution, GM’s battery supplier. But the company said an investigation has shown faults are possible in batteries made at other sites. Most new Bolt batteries are manufactured at an LG plant in Holland, Michigan.
GM issued Bolt’s first recall in November after receiving reports that five of them caught fire. Two people inhaled smoke and a house was set on fire.
At first, the company wasn’t sure what was causing the problem, but determined that the batteries that caught fire were almost fully charged. He traced the fires to what he called a rare manufacturing defect in battery modules. This can cause a short circuit in a cell, which can start a fire.
GM said it began investigating the new Bolts after a 2019 model that was not included in the previous recall caught fire a few weeks ago in Chandler, Ariz. This raised concerns about the new bolts.
The fire brought Bolt’s total number of fires to 10, company spokesman Dan Flores said.
GM says it is working with LG to increase battery production. The company says owners will be notified of the need to take their cars to dealerships as soon as the spare parts are ready.
Flores said he wasn’t sure when it would be.
The company has stated that it will not produce or sell any more bolts until it is satisfied that the issues have been resolved in LG batteries, Flores said.
“Our focus on safety and doing the right thing for our customers guides every decision we make at GM,” said Doug Parks, GM’s chief product development officer, in a statement.
The batteries with the new modules will be covered by an eight-year, 100,000-mile (160-kilometer) warranty, the company said. GM will replace all five battery modules in 2017 through 2019 Bolts. Defective modules will be replaced in newer models.
GM has said it will pursue reimbursement from LG.
Bolts make up a tiny fraction of GM’s overall sales in the United States, which runs nearly 3 million vehicles in a typical year. But they are the first in an ambitious rollout of electric models as GM tries to meet the goal of selling only electric passenger vehicles by 2035.
are also announcing additional electric models around the world to reduce pollution and meet more stringent government standards for fuel economy.
Shares of General Motors Co. fell about 2% on extended trading after the recall was announced.
