Bolt EV and Bolt EUV
As part of GM’s commitment to safety, experts from GM and LG have identified the simultaneous presence of two rare manufacturing defects in the same battery cell as the root cause of battery fires in certain Chevrolet Bolt EVs. As a result, GM will be conducting a recall of Bolt EVs (2017-2022) and Bolt EUVs (2022) to address the risk of battery fires in these vehicles.
What You Should Do
Out of an abundance of caution, GM will replace defective lithium-ion battery modules in Chevrolet Bolt EVs and EUVs with new lithium-ion modules. We will notify customers when replacement parts are ready. We are asking customers to take the following steps until the new remedy has been performed:
  1. Set your vehicle to a 90 percent state of charge limitation using Hilltop Reserve mode (for 2017-2018 model years) or Target Charge Level (for 2019-2022 model years) mode. Instructions on how to do this are available in the videos below. If you unable to successfully make these changes, or do not feel comfortable making these changes, GM is asking you to visit your dealer to have these adjustments completed.
  2. Charge your vehicle more frequently and avoid depleting their battery below approximately 70 miles (113 kilometers) of remaining range, where possible.
  3. Park your vehicle outside immediately after charging and do not leave your vehicle charging indoors overnight.

Chevrolet Bolt EV Battery Production Resumes

LG battery cell and module production resumes with updated manufacturing processes
Battery module replacements to begin in October
GM to introduce new advanced diagnostics software

DETROIT – General Motors today outlined a comprehensive action plan to ensure that customers can safely and confidently drive, charge, and park the Chevy Bolt EV and EUV. The action plan includes both hardware and software remedies, some of which are in place with immediate effect.

“We’re grateful for the patience of owners and dealers as we work to advance solutions to this recall,” said Doug Parks, GM executive vice president, Global Product Development, Purchasing and Supply Chain. “Resuming battery module production is a first step and we’ll continue to work aggressively with LG to obtain additional battery supply. In addition, we’re optimistic a new advanced diagnostic software will provide more convenience for our customers.”

New Battery Production

LG battery plants in Holland and Hazel Park, Michigan, have resumed production. In addition, LG is adding capacity to provide more cells to GM. As a result, replacement battery modules will begin shipping to dealers as soon as mid-October. The root cause of the rare circumstances that could cause a battery fire is two manufacturing defects known as a torn anode and a folded separator, both of which need to be present in the same battery cell. LG has implemented new manufacturing processes and has worked with GM to review and enhance its quality assurance programs to provide confidence in its batteries moving forward. LG will institute these new processes in other facilities that will provide cells to GM in the future.

Prioritized Battery Replacement

GM will continue to prioritize Chevy Bolt EV and EUV customers whose batteries were manufactured during specific build timeframes where GM believes battery defects appear to be clustered. The company has established a notification process that will inform affected customers when their replacement modules will be available. The new batteries will include an extended battery 8-year/100,000-mile limited warranty.

New Advanced Diagnostic Software

Within approximately 60 days, GM will begin launching a new advanced diagnostic software package that will increase the available battery charging parameters over existing guidance. The diagnostic software will be designed to detect specific abnormalities that might indicate a damaged battery in Bolt EVs and EUVs by: monitoring the battery performance; alerting customers of any anomalies; and prioritizing damaged battery modules for replacement. It is GM’s intent that further diagnostic software will allow customers to return to a 100 percent state of charge once all diagnostic processes are complete. This new software, which will be provided to all Bolt EV and EUV owners, requires dealer installation. Owners will be able to start to schedule installation at their Chevy EV dealer in approximately 60 days.

Updated Guidance on Parking

If customers are following GM’s instructions issued above, they can park in a location of their choice. In an abundance of caution, GM recommends customers leave ample space around their vehicle wherever they choose to park. GM is not aware of any fires that have occurred where customers followed this safety guidance, in parking decks or otherwise.

This limited parts warranty begins at the time of installation.
What confidence does GM have that the replacement modules won't have the same defects?
GM will only begin replacing battery modules in customer vehicles when GM and LG are confident in the safety of LG's product.
