VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect :
Description of the Defect : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain GLE and GLS vehicles (167 platform), the 48V ground connection under the passenger seat might have become loose.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : In this case, the ground cable lug would not be secured correctly.
Subsequently, the electric resistance of the connection might increase. In combination with the high electrical currents potentially flowing through this connection, the temperature in this area might increase. As a consequence, a risk of fire cannot be ruled out completely.
Description of the Cause : Due to deviations in the production process, the 48V ground connection under the passenger seat might have come loose during the assembly workflow. Identification of Any Warning
that can Occur : Before the issue occurs, the driver will not receive a warning due to the nature of the failure mechanism.
When the issue occurs, the driver might notice warning messages in the instrument cluster relating to the 48V onboard power supply. Involved Components : Component Name 1 : Hexagon Nut with Flange Component Description : Hexagon Nut with Flange Component Part Number : A0029906850 The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 24V-207 Page 5 Component Name 2 : Stud Component Description : Stud Component Part Number : A0009915303 Supplier Identification : Component Manufacturer
Name : MBAG Address : NR

Country : NR Chronology :
In June 2022, MBAG initiated an investigation of field reports from customers alleging that their 167 platform vehicles displayed battery-related warnings.
Based on an initial review of these field reports, MBAG hypothesized that insufficient tightening of the ground cable connection for the 48V ground connection under the front passenger seat during production rework could have contributed to the reported warning messages. In July and September 2022, MBAG initiated plant rework campaigns to tighten the ground cable connection in potentially affected vehicles that remained in MBAG’s control.
In September 2022, during the course of its worldwide product monitoring, MBAG identified additional field reports describing issues related to the subject 48V ground connection, however from vehicles that did not undergo rework of this ground connection during production.
From October 2022 through April 2023 MBAG conducted further investigations of worldwide field reports alleging conditions that could have resulted from a loose ground connection to analyze other processes or factors that could contribute to these occurrences. Additionally, between December 2022 and March 2023, MBAG conducted internal reviews of the assembly process for the 48V ground connection under the front passenger seat as well as the process for adjusting a bolted connection in a vehicle that did not meet torque specifications based on quality control testing during production. These analyses were not able to attribute the identified occurrence to any deviation in vehicle production or rework process or other systemic failure.
From April 2023 through January 2024, MBAG expanded its investigations of factors that could cause a loosening of this 48V ground connection. Based on this investigation, MBAG hypothesized that other mechanical rework operations in the physical proximity of, but unrelated to, this component could inadvertently potentially cause reduced torque.

Description of Remedy :
Description of Remedy Program : An authorized Mercedes-Benz dealer will check the bolting of the ground
connection on the affected vehicles and correct it, if necessary.
Pursuant to 49 C.F.R. § 577.11, MBUSA plans to provide notice about pre- notice reimbursement to owners since some of the involved vehicles would have been previously subject to the condition described.
How Remedy Component Differs from Recalled Component :
Vehicles outside of the recall population have the bolting of the ground connection according to production specifications.
Remedy Part No:
Hexagon Nut with Flange: A0029906850 Stud: A0009915303
Identify How/When Recall Condition was Corrected in Production :
The introduction of an additional gauge for the bolting of the ground connection ensures that the aforementioned issue can no longer occur from production date January 9, 2023 onwards. Recall Schedule :
Description of Recall Schedule : Dealers will be notified of the pending voluntary recall campaign on
March 22, 2024. Owners will be notified of the voluntary recall campaign before May 14, 2024. A copy of all communications will be provided when available.

covering, these component parts must be replaced.
Figure 5
Work Procedure B
1. Connect electrical wiring harness of 48 V on-board electrical system battery to “W106/1” ground point.
Torque of screw connection, electrical wiring harness to “W106/1” ground point: 20 Nm.
Torque of screw connection, ground harness to 48 V on-board electrical system battery: 16 Nm.
