Revision: 01
A labor time adjustment has been made in the Claims Information Section for Labor
Operation 9103746. Please discard all previous copies of bulletin 17386.

The reprogramming of the vehicles involved in this field action will be initially attempted by OnStar through
in-vehicle prompts from the radio display. The new software updates will enhance the functionality of the
vehicle’s Serial Data Gateway Module (SDGM) and the Bring Your Own Media (BYOM) radio. The overthe-air update process will be rolled out to vehicle owners in phases beginning April 2018 through August
2018. However, if the remote vehicle update is unsuccessful or the customer declines this service,
dealers will be required to reprogram the vehicle. This program is in effect until April 30, 2020.
All involved vehicles are identified by Vehicle Identification Number (VIN) on the Investigate Vehicle
History (IVH) screen in GM Global Warranty Management (GWM) system. During the service writeup process, dealership personnel should check IVH to determine if installation of the new
software package has already been completed. If the remote vehicle update has been
downloaded or installed, DO NOT install the update via USB. Otherwise, proceed to Update
Procedure Using TIS2WEB (USB Download).

Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management
system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections
and/or repairs.
Condition

Update

Certain 2017 model year Chevrolet Bolt EV vehicles need to be reprogrammed with an updated software
package. Depending on the vehicle’s configuration, it may require two updates. The software updates
will improve phone connectivity, display resolution, rear camera operation, and prevent instances of
intermittent screen freezing. The updates will also remove certain video playback functionality and
improve the ability to perform software updates to the radio.
OnStar will update vehicles remotely through in-vehicle prompts from the radio display. However, some
customers may decline the vehicle update or the update is attempted, but is not successful. In such
cases, dealers will be required to reprogram the vehicle with the new software updates.

Dealer Responsibility
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this program must be held and inspected/repaired per the update procedure of this bulletin before
customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealertraded, released to auction, used for demonstration, or any other purpose until the update has been completed.
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 and remedied per the update procedure in this bulletin. Upon submitting
an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified
for sale within the CPOIS system, or once again be used in the CTP program.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle,
or ownership, through April 30, 2020. Customers who have recently purchased vehicles sold from your vehicle inventory,
and for which there is no customer information indicated on the involved vehicle 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. Program 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 program enters your vehicle inventory, or is in your facility for service
through April 30, 2020, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.
Dealer Reports
For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and
Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. The listing may
contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor
vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in
several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to
complete this program.
Customer Notification
U.S.& Canada - General Motors will notify customers of this program on their vehicle (see copy of customer letter included
with this bulletin). When possible, involved U.S. customers will also be notified via e-mail.

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.

April 2018
This notice applies to your vehicle, VIN: ________________________________
Dear General Motors Customer:
As the owner of a 2017 model year Chevrolet Bolt EV vehicle, your satisfaction with our product is very important to us.
This letter is to inform you of new software updates that will soon be available for your vehicle. Depending on its
configuration, your vehicle may require two updates. The software updates will improve phone connectivity, display
resolution, rear camera operation, and prevent instances of intermittent screen freezing. The updates will also remove
certain video playback functionality and improve the ability to perform software updates to your radio. This service will
be provided for you at no charge.
We are rolling out the software updates to vehicle owners in phases beginning April 2018 through August 2018.
Updates will be performed remotely, through in-vehicle prompts from the radio display. When a software update
package becomes available for your vehicle, you will be notified through those in-vehicle prompts. To ensure
successful completion of the update, please review the enclosed information.
The download and installation of the software updates will occur in steps. You may be asked to accept the download of
the software update package. The vehicle must be parked to accept the download, but after the download is accepted,
you will be able to use your vehicle normally during the download process. Once the download is completed, you
will then be asked to accept the installation of the software update package. During installation of the software update
package, your vehicle must be parked. You may also notice one or more system resets during the installation
process.
IMPORTANT: You do not need to remain in your vehicle during the software installation. The vehicle cannot be
driven during the software install process (up to 10 minutes). The vehicle must be parked at a safe and secure
location with the ignition in the OFF position during installation. Please ensure that your charging cable is
unplugged prior to starting the installation. Once the installation is complete, you may plug in your vehicle and
resume normal charging.
For more information about the remote vehicle update process, please refer to the appropriate “Learn About Page” at:
my.chevrolet.com/learn/2017/Bolt%20EV
If you receive a message that the installation cannot continue or did not complete successfully, the installation process
may retry after your next ignition cycle. If the problem persists, please contact your dealer for assistance with the
software update.
You can also decline the update by selecting the “More Info” button, and then the “Decline Update” option. If you
decline the update, you can still receive it at a later date by contacting your dealer. This programming opportunity will
be in effect until April 30, 2020.
We want you to know that we will do our best, throughout your ownership experience, to ensure that your 2017 model
year Chevrolet Bolt EV vehicle provides you with many miles of enjoyable driving. If you have any questions, please
contact the Connection Center Team at 877-558-8352, 7:00 AM to 10:00 PM, Eastern Standard Time (EST), seven
days a week.
