A park-outside advisory is recorded. Verify applicability immediately with NHTSA or the manufacturer.
Reported concern
General Motors, LLC (GM) is recalling certain 2020-2022 Chevrolet Bolt EV and 2022 Bolt EUV vehicles previously repaired under Recall 21V-650. The installation of advanced diagnostic software may have failed. As such, the high voltage battery could catch fire when charged to full or nearly full capacity.
Manufacturer’s stated response
Owners are advised to take the following interim steps: Set the Target Charge Level feature in their vehicle to limit the charge level to 90%, charge their vehicle more frequently, avoid depleting the battery to 70 miles range remaining, park outside after charging, and do not charge the vehicle indoors overnight. Dealers will reinstall advanced diagnostic software, free of charge. Owner notification letters were mailed December 3, 2024. Owners may contact the Bolt EV Concierge Team at 1-833-382-4389.

Pedestrian alert soundsDP22005
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

Find investigation DP22005Electric Vehicle Battery FiresPE20016
In October 2020, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE) on 2017-2020 Model Year (MY) Chevrolet Bolt vehicles based on complaints received alleging that the vehicles caught fire under the seating area while parked and unattended. At the time, ODI had received 2 Vehicle Owner Questionnaires (VOQs) and several field reports. All complaints alleged vehicles caught fire during or after electrical charging.ODI's review found vehicle thermal events occurred during and/or at the end of the battery module charging cycle. The information learned from NHTSA and General Motors joint vehicle inspections prompted General Motors to file Recall 20V-701 on April 29, 2021. The remedy for this recall included 1) performing diagnostic procedures to identify and replace potentially defective battery cell-module assemblies and 2) installing onboard diagnostic software, designed to detect and warn owners regarding potential issues related to changes in battery module performance over time. Until this interim remedy became available for all affected vehicles, General Motors instructed their customers to enable ?Hilltop Reserve or ?Target Charge Level, based on the vehicle-equipped technology. Enabling these technologies would limit charging capacity of the battery module to a maximum of 90 percent. General Motors then continued to investigate the root cause of these battery cell module thermal events, which would lead them to their long-term recall remedy solution. Utilizing the information obtained from the Recall 20V-701 software update, General Motors and LG Energy Solutions,the supplier of the battery cell module pack along with LG Electronics,determined the root cause of the thermal events to be the result of two simultaneous manufacturing defects occurring in the same battery cell. The defect condition appears to be aggravated by routinely charging the battery to a full or nearly full state of charge after it has been substantially depleted. The two defects, located within the same battery cell module, would cause an internal short within the battery pack, resulting in the thermal events. The manufacturing process was changed to prevent the occurrence of these two defect conditions.On July 24, 2021, General Motors filed a defect information report recalling all 2017-2018 Chevrolet Bolt and certain 2019 Chevrolet Bolt vehicles with design level N2.1 battery cell produced at the LG Ochang, Korea plant. This remedy replaces defective battery cell-modules and will prevent potential thermal events from occurring during and/or at the end of the charge cycle. The recall (21V-560) includes vehicles that were remedied under 20V-701.General Motors continued to review new data after Recall 21V-560 and learned of an incident that occurred outside of the scope of the recall population. Additional analysis led General Motors and LGES to determine that the manufacturing defects defined by Recall 21V-560 were not isolated to one battery manufacturing plant. On August 21, 2021, General Motors filed a defect information report to expand the scope of recall 21V-560. The recall (21V-650) includes all 2019-2022 Chevrolet Bolt EV and 2022 Chevrolet Bolt EUV vehicles. In view of the recall actions being taken by General Motors, ODI is closing this Preliminary Evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances.The ODI reports cited above can be reviewed online at nhtsa.gov under the following identification numbers:11230072, 11425524, 11339878, 11365622, 11364692, 11427180, 11429891, 11374956, 11407212, 11372429, 11425225, 11415800
