Revision Description:
This bulletin is being revised to include an OTA option in the correction statement. Please discard all previous copies of A232424320. Also note that vehicles already remedied through Service Update Bulletin A232415800 are included and will show as closed in IVH for both A232415800 and A232424320.
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.
All involved vehicles that are in dealer inventory must be held and not delivered to customers, dealer traded, or used for demonstration purposes until the repair contained in this bulletin has been performed on the vehicle.
Involved vehicles will be repaired either through dealer repairs as described in this bulletin or through over the air (OTA) programming. Dealers can and should perform the procedure in this bulletin on any vehicle with an “open” status on the Investigate Vehicle History (IVH) screen in GM Global Warranty Management system. Due to the fact that vehicles will be closed in IVH through successful OTA programming, dealers should always check the status in IVH before performing any vehicle repairs.

Condition
General Motors has decided to conduct a safety recall for certain 2024 model year Buick Encore GX and Envista and Chevrolet Trax vehicles. The Virtual Cockpit Unit Module (VCU) in these vehicles may contain software that can cause the instrument panel display to intermittently blackout at vehicle startup or while driving. If the instrument panel display blacks out while driving, it may cause unnecessary diversion of the driver’s attention, increasing the risk of a crash.
Correction
General Motors will update the software in the vehicles’ Virtual Cockpit Unit Module (VCU) to correct the condition. Owners who have accepted applicable terms and conditions will have the opportunity to accept these software changes using wireless over-the-air (OTA) technology without having to bring their vehicle to a dealership. Alternatively, owners may schedule to have the updates performed at a GM dealer.
Parts
No parts are required for this repair.

• The Warranty Claim Code from the programming event must be accurately entered in the “Warranty Claim
Code” field of the transaction.
• When more than one Warranty Claim Code is generated for a programming event, it is required to document all
Warranty Claim Codes in the “Correction” field on the job card. Dealers must also enter one of the codes in the
“Warranty Claim Code” field of the transaction, otherwise the transaction will reject. It is best practice to enter
the FINAL code provided by SPS2.
Warranty Claim Code Information Retrieval
6125774
If the Warranty Claim Code was not recorded on the Job Card, the code can be retrieved in the SPS2 system as
follows:
1. Open TLC on the computer used to program the vehicle.
2. Select and start SPS2.
3. Select Settings (1).
4. Select the Warranty Claim Code tab (2).
The VIN, Warranty Claim Code and Date/Time will be listed on a roster of recent programming events. If the code is
retrievable, dealers should resubmit the transaction making sure to include the code in the SPS Warranty Claim Code
field.
Service Procedure
Caution: Before downloading the update files, be sure the computer is connected to the internet through a network cable
(hardwired). DO NOT DOWNLOAD or install the files wirelessly. If there is an interruption during programming,
programming failure or control module damage may occur.
Note: Carefully read and follow the instructions below.
Safety Recall

• 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.
• Please verify that the radio time and date are set correctly before inserting USB drive into vehicle for programming, otherwise an error will result.
• 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.
• The Engine Control Module (ECM) is the master module (for VIP vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the ECM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master module (for GEM vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the BCM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate.
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 Pre-Owned (CPO), courtesy transportation vehicles, dealer shuttle vehicles, CarBravo, etc. in dealers’ possession and subject to this recall must be held and inspected/repaired per the service procedure of this bulletin before customers take possession of these vehicles. 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 Pre-Owned (CPO) vehicles currently in the dealers’ inventory within the SHIFT Digital system will be de-certified and must be held and remedied per the service 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 SHIFT Digital system, or once again be used in the Courtesy Transportation 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 recall 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 recall and make every reasonable effort to implement the program correction as set forth in this bulletin prior to releasing the 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.

Your GM dealer will update the software in the vehicles’ Virtual Cockpit Unit Module (VCU) to correct the condition. Owners who have accepted the applicable terms and conditions may have already received the update with wireless OTA technology and will not have to bring their vehicle to a dealership. GM began prompting owners through the vehicle’s radio screen on November 6, 2023. Any owner having received this update through OTA technology will not have to bring their vehicle to a dealership. Alternatively, owners may schedule to have the updates performed at a GM dealer. This service will be performed for you at no charge.
What should you do?
A software update is available for your vehicle. The software update can be performed remotely using wireless OTA technology. If the update has completed, no further action is required. You may have already completed this update. You are able to verify that the update is complete using the steps below.
1. Open “Settings” from the radio home screen.

Chronology :
On August 17, 2023, GM’s Safety and Field Action Decision Authority (SFADA) decided to issue a service update
bulletin to update the VCU software in certain 2024 Buick Encore GX, Envista, and Chevrolet Trax vehicles to
correct an issue where the VCU software could, on rare occasions, cause the instrument panel display to
intermittently go black. On September 19, 2023, GM Korea representatives met with officials from the Korea
Automobile Testing & Research Institute (KATRI), during which KATRI indicated that it would require that this
condition be corrected through a safety recall rather than a service update.
GM is aware of 255 complaints globally (out of 75,677 vehicles) of instrument panel blackout received from
May 12, 2023 to September 25, 2023. GM is not aware of any accidents or injuries associated with this
condition. On October 30, 2023, and in response to KATRI’s demand, GM’s Safety and Field Action Decision
Authority decided to conduct this previously launched field action as a safety recall.
Description of Remedy :
Description of Remedy Program : General Motors will update the software in the vehicles’ Virtual Cockpit
Unit Module (VCU) to correct the condition. Vehicles that received
updated software through GM’s previously launched service update
bulletin are not included in this recall.
Pursuant to 49 C.F.R. § 573.13(d)(1), all covered vehicles are under
warranty, so reimbursement is not offered.

Address : 10, Magok-10ro, Gangseo-gu,
Seoul Foreign States 07796
Country : Korea, Republic of
Chronology :
On August 17, 2023, GM’s Safety and Field Action Decision Authority (SFADA) decided to issue a service update
bulletin to update the VCU software in certain 2024 Buick Encore GX, Envista, and Chevrolet Trax vehicles to
correct an issue where the VCU software could, on rare occasions, cause the instrument panel display to
intermittently go black. On September 19, 2023, GM Korea representatives met with officials from the Korea
Automobile Testing & Research Institute (KATRI), during which KATRI indicated that it would require that this
condition be corrected through a safety recall rather than a service update.
GM is aware of 255 complaints globally (out of 75,677 vehicles) of instrument panel blackout received from
May 12, 2023 to September 25, 2023. GM is not aware of any accidents or injuries associated with this
condition. On October 30, 2023, and in response to KATRI’s demand, GM’s Safety and Field Action Decision
Authority decided to conduct this previously launched field action as a safety recall.
Description of Remedy :
Description of Remedy Program : General Motors will update the software in the vehicles’ Virtual Cockpit
Unit Module (VCU) to correct the condition. Owners who have accepted
applicable terms and conditions will have the opportunity to accept these
software changes using wireless over-the-air (OTA) technology without
having to bring their vehicle to a dealership. Alternatively, owners may
schedule to have the updates performed at a GM dealer.
Pursuant to 49 C.F.R. § 573.13(d)(1), all covered vehicles are under
warranty, so reimbursement is not offered.
How Remedy Component Differs
from Recalled Component :
The updated VCU software will correct the condition.
Identify How/When Recall Condition
was Corrected in Production :
Corrected software was fully implemented in production by August 5,
2023.
Recall Schedule :
Description of Recall Schedule : Dealers will be notified on November 6, 2023. Owner notification is
estimated to begin on December 22, 2023.
Planned Dealer Notification Date : NOV 06, 2023 – NOV 06, 2023
