IMPORTANT SAFETY RECALL
May 2021
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.
Previously, you were notified that your 2019 model year Chevrolet Bolt EV was involved in GM recall N202311730. This letter is to inform you that the final remedy service procedure is now available to repair your vehicle under N202311731.
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 safety recall N202311731.
• Schedule an appointment with your GM dealer.
• This service will be performed for you at no charge.
Why is your vehicle being recalled?
A certain number of these vehicles were built with high voltage cells 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?
Your GM dealer will perform diagnostic procedures on your vehicle and, if necessary, replace battery module assemblies that fail the diagnostics. Your dealer will also install advanced onboard diagnostic software that, among other things, has the ability to detect potential issues related to changes in battery module performance before problems can develop.
This service will be performed for you at no charge. In most cases, the inspection and service will take approximately one hour. If the replacement of a battery module assembly is required, your dealer will provide you with a courtesy loaner vehicle while your vehicle is being repaired, which could take several days, depending on parts availability.
What should you do?
You should contact your GM dealer to arrange a service appointment as soon as possible.
When scheduling your appointment, confirm with the dealer that they are an EV certified dealer.

LEADERSHIP MESSAGE
Check out the newest edition of “Chevy 0 to 60″.
This segment touches on today’s Bolt EV safety recall for select 2017-2019 model years.
For details, please see recall bulletins – N212343880 and N202311731-02.
Owners can visit my.chevrolet.com/how-to-support/safety/boltevrecall or contact the Chevrolet EV Concierge at 1.833.EVCHEVY.
Thank you for everything you do for Chevrolet. As always, let us know what you think.
VIDEO TEXT:
Chevy Team – Today, at 9am, we’re announcing a new recall for the previous population of select 2017 through 2019 Bolt EVs.
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 Bolt EVs.
Now, as a result, GM will conduct this new recall for this previous population to address the risk of battery fires in these vehicles.
As part of this recall, GM will replace defective battery modules in the recall population.
When replacement parts are ready, we will notify both the customer and you, our Dealers.
While we prepare to conduct this recall, we’re asking customers to take several steps that are outlined in the dealer bulletins and will be outlined in the customer letter and on the website and this will be until the new remedy has been performed.
As always, if customers need support we need to be there for them.
In the meantime, customers who have not received the diagnostics software from the last recall, should visit your dealership to obtain this update.
So, let’s break down a few questions that you might have:
1) Is there a stop sale on the 2020, 21, 22 Bolt EV or EUV?
The answer is no – keep selling.
The 2020, 21, 22 Bolt EV & EUV batteries have a different battery cell chemistry and were produced with improved manufacturing processes.
2) I’ve got a 2017 through 2019 Bolt EV on my used car lot, that is affected by this recall, what do I do?
Don’t sell it because it has an active recall.
3) Is this the same population of vehicles from November?
Yes – it’s the same population of vehicles but a new recall . . . affecting about 50,000 vehicles in the U.S.
In terms of timing … We are announcing the recall this morning.
And we will notify customers by mail and email starting next week.
We’re working with our supplier and manufacturing teams to determine how to best expedite battery capacity for module replacement under this recall.
This is what we know today . . .
Just like with the microchip situation, you have my commitment to provide ongoing and transparent updates on this issue.
What you’re going through right now is not lost on me.
This recall does provide an opportunity to once again, deliver an exceptional customer experience.
And no one does it better than this Chevy network.
Thank you for all that you do.
We’ll be talking to you soon.

EV Battery Fire
NHTSA ID: PE20016
Dated opened: October 9, 2020
The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) has received two Vehicle Owner Questionnaires (VOQs) regarding a model year (MY) 2018 and a MY 2019 Chevrolet Bolt EV and alleging that the vehicles caught fire under the rear seat while parked and unattended.
ODI conducted additional research, and found a MY 2017 Bolt EV with a similar burn pattern in the interior rear seat area.
In the three cases identified, fire damage appeared to be concentrated in the EV battery compartment area with penetration into the passenger compartment from under the rear seat. The root cause of these fires is unknown. One of these incidents, ODI 11230072, reported smoke inhalation injuries.
ODI is opening a Preliminary Evaluation to assess the scope, frequency, circumstances, and safety consequences of the alleged fires.
The reports cited above can be reviewed at NHTSA.gov under the following reference numbers: 11230072, 11339878.
Reprogramming
GM Diagnostic/Programming (TIS2Web)
Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.
To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle's 17 character Vehicle Identification Number (VIN) and select 'Get CAL ID’.
You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.
The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.
The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.
Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle. The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles.
The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.
