IMPORTANT SAFETY RECALL
November 2020
This notice applies to your vehicle, VIN: __________________________________
Dear General Motors Customer:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2017-2019 model year Chevrolet Bolt EV vehicles. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.
IMPORTANT
• Your vehicle is involved in GM recall N202311730.
• Beginning on November 17, 2020, please schedule an appointment with your Chevrolet dealer.
• This service will be performed for you at no charge.
• This letter also contains important interim charging instructions for your vehicle. Please review these instructions before charging your vehicle.
Why is your vehicle being recalled?
A certain number of these vehicles were built with high voltage batteries produced at LG Chem’s Ochang, Korea facility that may pose a risk of fire when charged to full, or very close to full, capacity.
What will we do?
While our investigation into this condition continues, GM has developed software that will limit vehicle charging to 90% of full capacity to mitigate this risk. This software will be available at your Chevrolet dealer on November 17, 2020. Your Chevrolet dealer will reprogram your vehicle’s hybrid propulsion control module to limit full charge to 90%. This service will be performed for you at no charge. Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual inspection and service correction time of approximately 25 minutes.
We are working around the clock on our continued investigation and we intend to deploy a final remedy and remove the 90% limitation as soon as possible after the first of the year. When that remedy is available, we will send you another letter asking you to take your vehicle to your Chevrolet dealer to have your vehicle serviced, free of charge.
What should you do?
Beginning on November 17, 2020, you should contact your Chevrolet dealer to arrange a service appointment as soon as possible. Until your vehicle’s battery system has received the updated software, you should take one of the following interim steps:
(Model Years 2017-18 Only): Activate the Hill Top Reserve feature in your vehicle. This feature, when activated, will limit your vehicle’s battery to 90% of full capacity. For assistance activating this feature, please watch the instructional video at www.chevy.com/boltevrecall.
(Model Year 2019 Only): Activate the Target Charge Level feature in your vehicle, and set the target-charge level to 90%. For assistance activating this feature, please watch the instructional video at www.chevy.com/boltevrecall.
(All Model Years): If you are unable or uncomfortable enabling one of the above described charge-limiting features in your vehicle, you should park your vehicle outside as soon as your vehicle completes a full battery charge.
Do you have questions?
If you have questions or concerns that your dealer is unable to resolve, please contact the Bolt EV Concierge team at 833-EVCHEVY (833-382-4389). Hours of operation are Monday through Friday, 8:00 AM to 7:00 PM ET.
If after contacting your dealer and the Customer Assistance Center, you are still not satisfied we have done our best to remedy this condition without charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Avenue, SE., Washington, DC 20590, or call the toll-free Vehicle Safety Hotline at 1.888.327.4236 (TTY 1.800.424.9153), or go to https://www.safercar.gov. The National Highway Traffic Safety Administration Campaign ID Number for this recall is 20V701.
Federal regulation requires that any vehicle lessor receiving this recall notice must forward a copy of this notice to the lessee within ten days.

This bulletin has been revised to update the vehicle table and the Attention box. Please discard all previous copies of bulletin N202311730.
Attention:
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.

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 and subject to this recall must continue to be held following the successful completion of the interim service procedure in this bulletin. A final repair is not available at this time. When a final repair is available, the service procedure in this bulletin will be revised and dealers will be notified. Until a final repair is available and completed by the dealer, involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.
Product Safety Recall
N202311730 High Voltage Battery May Melt or Burn
Page 5 of 7
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 a FINAL service procedure is available and completed. The interim remedy in this bulletin DOES NOT allow the vehicle to be sold or re-certified.
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. A copy of the customer letter is provided in this bulletin for your use in contacting customers. 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 interim correction has been made. 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 interim 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 (see copy of customer letter included with this bulletin).
Export – Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.
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.

STOP DELIVERY ORDER
Effective immediately, stop the delivery of select 2017-2019 model year Chevrolet Bolt EV vehicles in new or used vehicle inventory. General Motors has notified the National Highway Traffic Safety Administration (NHTSA) about an upcoming safety recall that involves these vehicles. The GM recall number is N202311730.
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 until the defect is remedied.
General Motors has decided that a defect which relates to motor vehicle safety exists in select 2017-2019 model year Chevrolet Bolt EV vehicles. A select number of these vehicles were built with high voltage batteries produced at LG Chem’s Ochang, Korea facility that may pose a risk of fire when charged to full, or very close to full, capacity.
As an interim remedy, dealers will reprogram the hybrid propulsion control module 2 (HPCM2) to limit full charge to 90%. GM expects this software to be available at GM dealers on November 17, 2020. Until this interim remedy is completed, customers should enable either “Hilltop Reserve” (for 2017-2018 model year vehicles) or “Target Charge Level” (for 2019 model year vehicles) using their vehicle’s infotainment center. These two features will limit the vehicle’s state of charge to 90% until the HPCM2 software recalibration is applied. If customers are unable to successfully make these changes, or do not feel comfortable making these changes, they will be advised to not park their car in their garage or carport until after they have visited their dealer.
Until further instructions are received, involved vehicles in dealers’ possession (new or used vehicle inventory, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc.) must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration purposes or any other dealer use. All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified.
The Investigate Vehicle History (IVH) screen in the Global Warranty Management (GWM) system will be updated for this upcoming recall by November 13, 2020. This action has been taken to assist dealers with determining which vehicles are involved so they can properly respond to customer inquiries.
A list of involved vehicles that have been identified as being in dealer new vehicle inventory is attached to this message. It is sorted by dealer Business Associate Code
(BAC) for easy reference. Your dealership’s BAC will not be listed if none of the involved vehicles are currently in your new vehicle inventory.
Until the recall bulletin is released, the Investigate Vehicle History (IVH) screen in the Global Warranty Management (GWM) system will display “N/A” under Release Date and “Incomplete – Remedy not yet available” under Status. This means the required repair is not yet available and dealers should not attempt to perform any repairs.

Subject: N202311730 – Safety Recall
High Voltage Battery May Melt or Burn
Application for Used Vehicle Working Capital Assistance Program (WCAP)
Models: 2017-19MY Chevrolet Bolt EV
To: All General Motors Dealers
On November 13, 2020, GM sent to all GM dealers GlobalConnect Message GCUS-3-1963 regarding safety recall N202311730.
The required repair to complete this recall is not yet available. Until further instructions are received, the involved vehicles that are in dealers’ possession (new or used vehicle inventory, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc.) must be held and cannot be delivered to customers, dealer-traded, released to auction, used for demonstration purposes or put to any other use.
This message is to inform dealers who have involved vehicles in their inventory that they can now apply for the used vehicle Working Capital Assistance Program (“WCAP”) for safety recall N202311730.
Before proceeding with the application process described below, dealers must verify vehicle eligibility based on the program terms and guidelines that were provided in GM GlobalConnect Message GCUS-9-9188 dated March 10, 2020. Applications submitted on ineligible vehicles are subject to chargeback of any incentives paid to the dealer under the WCAP. Because compensation and tracking requires visibility into dealers’ inventory, dealers must also have agreed to a Dealer Data Share agreement with GM in order to receive any compensation under this program.
To apply for the WCAP for safety recall N202311730, dealers must access the GM Global Warranty Management (GWM) system and submit a “ZSET” warranty transaction using the labor code provided below for each eligible vehicle. This zero dollar special transaction type is the dealer’s application for compensation and constitutes a representation from the dealer that the vehicle is eligible for WCAP assistance.
Note: Acceptance of the warranty transaction does not ensure vehicle eligibility or guarantee the provision of any assistance as defined by program terms and guidelines.

Working Capital Assistance for Safety Recall N202311730

ZSET
To be eligible for the WCAP, a vehicle must be in dealer inventory at the time the related field action bulletin is released. If a vehicle has been delivered, wholesaled or otherwise disposed of prior to release of the bulletin, the vehicle is not eligible for assistance. Additionally, recalled vehicles taken in on trade may be eligible for assistance if the dealer immediately reports the vehicle in used vehicle inventory via its Dealer Management System (DMS) and makes application through the GWM system.
To ensure that GM is receiving daily inventory information, which is necessary to process payments and make eligibility determinations under the WCAP, the dealer’s vehicles must be properly identified in the dealership’s DMS. A daily feed of this information is provided to GM through the Dealer Data Share (DDS) agreement.
Beginning with the 1st quarter of 2019, all WCAP payments will be facilitated through the Global Warranty Management (GWM) system. For each eligible vehicle, a qualifying dealer will submit for WCAP vehicle enrollment with a “ZSET” transaction type and for reimbursement with a “ZFAT” transaction type both through the GWM system. If approved, a WCAP credit for that vehicle will be issued through the GWM system similar to any other warranty credit. WCAP submission instructions and the required labor code will also be provided in the appropriate field action bulletin. Each WCAP transaction being credited will be clearly identified on the dealer’s daily credit memo.
In order to receive payment, a dealer must have timely reported the vehicle in used vehicle inventory, retained the vehicle until the related field action bulletin is released, and properly applied for the WCAP payment. The vehicle must also be otherwise eligible under WCAP rules and guidelines.
GM reserves the right to amend, modify, terminate, or cancel this program at any time in its sole discretion.

The arrival of the postcard may lead an owner of a 2017/18MY Bolt EV to incorrectly believe the final remedy is available for their vehicles. As we have previously communicated in Global Connect message GCUS-3-2162, the final remedy for the 2017/18MY vehicles is not available now. If you are contacted by a 17-18MY owner who received a postcard, please remind them the final remedy is not yet available for their vehicle. General Motors will have the 2017-18 model year final remedy available for dealers and customers by the end of May. We apologize for any confusion this has caused.
