Recall Campaign Launch Notification				March 19, 2021
Campaign No. :	CA DMV. :	Campaign Desc. :		Battery Management System Software
2020070002	200702	20P5497511
This is to notify you of the Emissions Recall Campaign LAUNCH concerning the battery management system software on 12 MY 2019 Model S560e hybrid vehicles (222 platform). A customer notification letter will be mailed to customers advising of this emissions recall, which may generate questions.  Affected VINs will be flagged in VMI as “OPEN” on March 19, 2021
Background
Issue		Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, determined that on certain S-Class S560e hybrid vehicles (222 platform), the battery management system  software for the high voltage battery might not meet applicable specifications. In this case, the fault memory of the engine control unit would be cleared each time the battery management system is powered up during a “cold start” or a restart within five minutes after idle. Therefore, an OBD or emission relevant defect might not be confirmed in the engine control unit and so might not be indicated by a MIL.  In this case, applicable requirements might not be fulfilled.
What We’re Doing		MBUSA will conduct a voluntary Emissions Recall Campaign. An authorized Mercedes-Benz dealer will update the battery management system software.
Parts		Parts are not required for this campaign since the remedy is software based.
Vehicles Affected
Vehicle Model Year(s)		2019
Vehicle Model		S-Class
Vehicle Populations
Total Recall Population		12
Notice to California Dealers: As required by 13 CCR 2117, a proof of correction (“POC”) certificate showing that the vehicle has been repaired under this recall must be issued by the authorized service facility, and that such a certificate may be required by California as a condition of vehicle re-registration or operation.  Please reference this POC in the attached work instructions.  Failure to complete this step may result in fines and penalties and lead to customer dissatisfaction.
Next Steps/Notes
Customer Notification Timeline			A customer notification will be provided for this Emissions Campaign. Customer letters will be mailed on March 26, 2021
AOMS/SOMS			AOMs – This campaign may generate questions from your dealers.  Please forward this notice to your dealers ASAP.
While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle quality and customer satisfaction. Please refer all customer inquiries to the Customer Assistance Center at 1-800-FOR-MERCEDES.

Campaign No. 2020070002, March 2021

 

TO:	ALL MERCEDES-BENZ CENTERS
SUBJECT:	Model S-Class (222 platform) Model Year 2019 Update the Battery management system (BMS) software

 

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2019 S-Class S560e hybrid (222 platform) vehicles, the Battery Management System (BMS) software for the high-voltage battery might not meet current production specifications. In this case, the fault memory of the engine control unit would be cleared each time the BMS is powered up during a “cold start” or a restart within five minutes after idle. Therefore, an OBD or emission relevant defect might not be confirmed in the engine control unit and thus, might not be indicated by the MIL. In this case, applicable requirements might not be fulfilled. In addition, due to resetting various diagnostics, the vehicle might not pass a SMOG check. An authorized Mercedes-Benz dealer will update the BMS software.

 

Prior to performing this Recall Campaign:

• VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly.
• Please review the entire Recall Campaign bulletin and follow the repair procedure exactly as described.

 

Please note that Recall Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.

Approximately 12 vehicles are involved.

 

Order No. P-RC-2020070002

This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data Control, and MBUSA-SLP S424HH001, Control of Quality Records.
