Important: Verify the vehicle SOC is less than 80%. This can be determined by looking at the bars on the power level indicator. If four or more empty bars (not showing green) are displayed, the SOC is at an acceptable level. If the power level indicator shows an SOC of greater than 80% The SOC must be adjusted before proceeding with the recalibration.
Caution: During this procedure, a puddle of water may form around the vehicle from HVAC system drainage. Use care to prevent any slip/fall conditions.
Note: Each hour of operation will reduce SOC by about 10%. Left unattended, the vehicle will automatically turn OFF after 2 hours. This procedure must be performed in a secure location because the vehicle is in a drivable condition. Take proper steps to ensure no unauthorized drivers have access to the vehicle.
If required, reduce the SOC as follows:
• Vehicle in PARK, Vehicle ON.
• Headlamps Low Beam: ON.
• Temp Control: Hi (Max Heat High) (note: windows should be down).
• Distribution: MAX Defrost (Engages AC Compressor).
• Fan Speed: High (8).
• Select: Fresh Air (Not recirc).
• Select: Heat & A/C .
• If equipped, turn heated seats to hi position.
• Verify SOC after 60 minutes. If the SOC is still greater than 80%, allow additional time for the loads listed above to reduce the SOC to less than 80%.
• When the SOC adjustment is completed return the HVAC controls to 72 Deg. AUTO, Set the headlamp control to AUTO.
Programming
Note: Carefully read and follow the instructions below.
• Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector. If there is an interruption during programming, programming failure or control module damage may occur.
• Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Install a GM Authorized Programming Support Tool to maintain system voltage. Refer to www.gmdesolutions.com for further information. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
• Follow the on-screen prompts regarding ignition power mode but ensure that anything that drains excessive power (exterior lights, HVAC blower motor, etc.) is off.

Page 3 of 7
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M)
system status indicators to NO.
Important: The service technician always needs to verify that the VIN displayed in the TLC left side drop down menu
and the top center window match the VIN plate of the vehicle to be programmed prior to using Service
Programming System 2 (SPS2) for programming or reprogramming a module.
• For the TLC application, service technicians need to always ensure that the power mode (ignition) is “ON” before
reading the VIN from the vehicle’s VIN master module and that they do not select a VIN that is already in the
TLC application memory from a previous vehicle.
• If the VIN that shows up in the TLC top center window after correctly reading the VIN from the vehicle does not
match the VIN plate of the vehicle, manually type in the VIN characters from the vehicle VIN plate into the TLC
top center window and use these for programming or reprogramming the subject module with the correct vehicle
VIN and software and/or calibrations.
Caution: Be sure the VIN selected in the drop-down menu (1) is the same as the vehicle connected (2) before
beginning programming.

Dealer Responsibility – For USA & Export (USA States, Territories, and Possessions)
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Dealer Responsibility – All
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers’ possession are subject to this recall. Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held until the final remedy is completed. Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle is not re-certified for sale within the CPOIS system, and cannot be used in the CTP program.
Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter. In summary, whenever a vehicle subject to this field action enters your vehicle inventory you must take the steps necessary to ensure the program correction has been made before selling the vehicle. In addition, for vehicles entering your facility for service, you are required to ensure the customer is aware of the open field action and make every reasonable effort to implement the program correction as set forth in this bulletin prior to releasing the vehicle.
Dealer Reports
For dealers with involved vehicles, a listing has been prepared and will be available through GM GlobalConnect Maxis Field Action Reports or sent directly to export dealers. The Inventory tab of the dealer reports will contain VINs that apply to this recall. This information is intended to assist dealers with the PROMPT COMPLETION of these vehicles. The Customer In-Service tab will contain customer names and addresses from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall may be a violation of law in several states.
Courtesy Transportation – For USA & Canada
Courtesy transportation is available for customers whose vehicles are involved in this safety recall.
Customer Notification
USA & Canada – General Motors will notify customers of this recall on their vehicle.
Export – Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act.
GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.

To: All General Motors Dealers
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 below, 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.
GM’s instructions remain:
1. Set the vehicle to a 90 percent state of charge limitation using Target Charge Level mode. Instructions on how to do this are available on chevy.com/boltevrecall. If customers are unable to successfully make these changes, or do not feel comfortable making these changes, GM is asking them to visit their dealer to have these adjustments completed.
2. Charge the vehicle more frequently and avoid depleting battery below approximately 70 miles (113 km) of remaining range, where possible.
3. Continue to park vehicles outside immediately after charging and do not leave vehicles charging indoors overnight.
Customers who have additional questions can visit www.chevy.com/boltevrecall or contact the Chevrolet EV Concierge 1-833-EVCHEVY (available Monday through Friday, from 8 a.m. – midnight ET; Saturday and Sunday, from noon – 9 p.m. ET) or contact their preferred Chevrolet EV dealer.

2017-2018 model year vehicles have been added and the programming steps of the service procedure in this bulletin have been revised. Please discard all previous copies of bulletin N212343883.
General Motors has developed an advanced diagnostic software package in N212343883-01 that will remove parking and charging limitations on 2017-2019 MY Chevrolet Bolt EV vehicles that have not yet received their replacement battery module. This software is not the final remedy, and customers will be notified when battery modules are available for replacement under Safety Recall N212343881.
The new software automatically sets the vehicle’s maximum state of charge to 80%, allowing owners to safely resume:
• charging indoors overnight;
• depleting their vehicle’s battery below 70 miles (113 km) of range, resulting in greater overall vehicle range compared to GM’s prior interim charging guidance; and,
• parking indoors after charging.
This software also contains new diagnostics designed to detect specific abnormalities that might indicate a rare battery issue in the vehicle.
IMPORTANT: The information referenced in this message contains a service procedure that WILL NOT close the recall.

This recall must only be completed by Chevrolet EV certified dealers who have met all Bolt recall-specific training, tool and equipment requirements. Repairs must be performed by a technician who has successfully completed the required training. Any dealership unsure of their eligibility status should review with their District Service Manager.

GLOBAL SAFETY FIELD INVESTIGATIONS DCS6014 URGENT – DISTRIBUTE IMMEDIATELY Date: December 21, 2021 Subject: Bolt EV/EUV Parking Update Cling Sticker Models: 2017-2022 Bolt EV and Bolt EUV Vehicles To: All General Motors Chevrolet Dealers As battery module replacements continue and advanced diagnostics software is now available for all Bolt EV/EUV owners, Chevrolet has created a “Chevrolet Certified” window cling for owners who have either had their battery modules replaced or the latest advanced diagnostics software installed in their vehicles. These clings feature a QR code that parking lot attendants and garage owners can scan to confirm that the particular Bolt EV/EUV has been serviced. Clings should be provided directly to the owner to be used at their discretion. If the owner requests the dealership to apply the cling to their vehicle, it should be put in an area of the windshield visible from the outside but not obstructing the driver’s view. GM decided to make this cling available as the result of direct feedback from our owners. These clings should be made available ONLY to owners who have completed either the Advanced Diagnostic Software updates outlined in recall bulletins N212343883 (17-19MY) / N212345940 (20-22MY) or the battery module replacements outlined in recall bulletins N212343881 (17-19MY) / N212345941 (20-22MY). These clings are being shipped to your dealership based on the volume of VINS currently estimated to be repaired at your location. We expect the clings begin arriving at dealers in early January 2022. If you run out and need to order more, you will be able to do so through the GM 1Store in Global Connect. Go to the 1Store and search for “Bolt Update Label”. When dealers order a quantity of one (1) through the 1Store, they will receive a sheet that contains eight (8) window clings.
If you have customers that have already completed either the battery module replacement or the advanced diagnostic software, we recommend contacting the owner and, if the cling is requested, mail directly to their address of choice. A list of Frequently Asked Questions is attached to this message to assist dealers in answering customer questions regarding the cling. Thank you for your continued commitment to keeping our customers at the center and appreciate your continued patience.
FAQs:
Q: Why was it necessary to provide something like this to owners?
A: There has been on-going confusion around Bolt EVs and EUVs and parking garages or parking lots. Some garages and parking lots had inappropriately denied access to Bolt EVs and EUVs without consideration of whether or not the owners were following GM’s published charging guidelines. Having heard from owners that this was happening, we decided to provide a visible indication that customers have had their hardware replacement performed or had the interim software remedy performed, either of which lifts GM’s previous charging and parking guidance.
Q: You indicated the window cling has a QR code. Where does that direct to and what
information is provided when the QR code is scanned?
A: The user will be directed to a special website that will feature the following text:
Certification confirming vehicle has had recommended battery software update or defective battery module replacement performed at a Chevrolet Dealership. The certified battery update removes charging and parking limitations.
For additional information please visit: www.chevy.com/boltevrecall.
Q: How can owners obtain a window cling if they have completed their battery module
replacement or received the latest software update?
A: Owners who have already completed their battery module replacements or received the latest advanced diagnostics software update can request a window cling from the Chevrolet dealer which completed their battery or software update. Going forward, dealers will provide a window cling to owners once they have completed either the module replacements or software update.

Models: 2017 – 2019 Chevrolet Bolt EV
To: All General Motors Dealers
Additional 2017 – 2019 model year Chevrolet Bolt EV vehicles have been moved to ‘Open’ status in IVH and are now eligible for a battery module replacement in bulletin N212343881. Please verify a VIN’s involvement in this field action by checking in IVH prior to doing any repairs. The Dealer Maxis App via Global Connect can be utilized to download a list of eligible ‘open’ VINs. Dealer Maxis should be queried at a minimum weekly for the most up-to-date information on all open field actions. IVH is the best source for individual VIN inquiries.
As VINs become eligible for a battery module replacement in N212343881, they will be closed in N212343883. Dealers will be informed as additional VINs become eligible for final repair in bulletin N212343881.
All remaining VINs in N212343883 with an “Incomplete-Remedy Not Available” status are eligible to receive the advanced diagnostic software package.
WCAP is calculated from the “Release Date” on VINs in “Open” Status in IVH and will be adjusted as additional releases occur.
When making customer appointments, please remind the customer to not charge their vehicle 24 hours prior to their scheduled appointment. Not charging the vehicle before the service appointment and ensuring that the battery’s state of charge is at 90% or less will help speed up the repair procedure.
Until the battery module is replaced (N212343881), OR the vehicle receives the advanced diagnostic software package (N212343883), customers should take the following interim steps:
1. Set their vehicle to a 90 percent state of charge limitation using Hilltop Reserve mode (for 2017-2018 model years) or Target Charge Level (for 2019 model year) mode. Instructions on how to do this are available on
(chevy.com/boltevrecall). If customers are unable to successfully make these changes, or do not feel comfortable making these changes, GM is asking them to visit their Chevrolet EV certified dealer to have these adjustments completed.
2. Charge their vehicle more frequently and avoid depleting their battery below approximately 70 miles (113 km) of remaining range, where possible.
3. Continue to park their vehicles outside immediately after charging and not leave their vehicles charging indoors overnight.
