Chronology :
In October 2023, MBAG launched initial investigations based on a finding on an internal vehicle during a standard quality control. This finding indicated a contact between the wiring harness and the drive shaft.
Immediately, analyses on the root cause were started and further tests on internal vehicles were performed to verify the issue. In December 2023, an additional quality check in the assembly line was introduced to check for sufficient distance between wiring harness and drive shaft.
Starting in January 2024, possible consequences for the vehicles in the field were analyzed and relevant regulations were researched. Furthermore, a plant campaign was initiated to rework all vehicles still in the control of MBAG, and analyses were performed to identify the potentially affected vehicles in the field.
On March 15, 2024, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall.
MBAG can confirm there are no warranty claims, field or service reports, and other information (such as the numbers of deaths and/or injuries) related to this defect in the USA.

Country : NR Chronology :
In October 2023, MBAG launched initial investigations based on a finding on an internal vehicle during a standard quality control. This finding indicated a contact between the wiring harness and the drive shaft. Immediately, analyses on the root cause were started and further tests on internal vehicles were performed to verify the issue. In December 2023, an additional quality check in the assembly line was introduced to check for sufficient distance between wiring harness and drive shaft.
Starting in January 2024, possible consequences for the vehicles in the field were analyzed and relevant regulations were researched. Furthermore, a plant campaign was initiated to rework all vehicles still in the control of MBAG, and analyses were performed to identify the potentially affected vehicles in the field.
On March 15, 2024, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall. MBAG can confirm there are no warranty claims, field or service reports, and other information (such as the numbers of deaths and/or injuries) related to this defect in the USA. Description of Remedy :
Description of Remedy Program : An authorized Mercedes-Benz dealer will check the routing of the
transmission wiring harness on the affected vehicles and rework it, if necessary. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since none of the involved vehicles would have been previously subject to the condition described and all remain covered under the new vehicle warranty.
