On August 20, General Motors voluntarily expanded the Chevrolet Bolt EV recall to cover 2019 and 2020-2022 models, including the Bolt EUV.
According to General Motors, in rare cases, there may be two manufacturing defects in the batteries of these vehicles: anode cracking and separator folding, which increase the risk of fire. Out of caution, General Motors will replace the defective battery modules in the Chevrolet Bolt EV and EUV with new ones, with an expected additional cost of about $1 billion.
After further investigating LG’s manufacturing process and disassembling the battery packs, General Motors found that certain batteries produced in LG’s manufacturing facilities outside of Korea’s Ochang factory have manufacturing defects. General Motors and LG are working to correct the cause of these defects. Meanwhile, General Motors is seeking LG’s commitment to compensate for this on-site action.
To reassure customers, the batteries equipped with these new modules will provide an 8-year / 100,000-mile limited warranty (or an 8-year / 160,000-kilometer limited warranty in Canada).
If General Motors cannot reach an agreement with LG, the Ultium battery partnership may be at risk.
