Update Transmission Control Unit Software
This is to notify you of the Recall Campaign Update to update the transmission control unit software in 104,851 Model Year (“MY”) 2020-2023 GLE/GLS (167 platform) vehicles. The recall campaign is visible on the www.NHTSA.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on March 15, 2024.
Issue
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2020–2023 GLE/GLS (167 platform) vehicles equipped with the 6-cylinder gasoline engine and 9-speed transmission, the transmission control unit software might not meet current production specifications. If a downshift of the transmission from 7th to 6th gear is not fully completed during a simultaneous slight braking maneuver of the vehicle, and additional conditions exist (e.g. aborted shift operation, low transmission oil temperature, simultaneous recuperation by the 48V starter-alternator), the engine might stall. In that event, the vehicle would lose propulsion, which could increase the risk of a crash. When the vehicle comes to a standstill the engine can be restarted. This occurrence does not affect the functionality of the vehicle’s steering and braking systems.
What We’re Doing
MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will update the transmission control unit software on the potentially affected vehicles.
Parts
The remedy is available and can be performed.
Given this notice, it is a violation of Federal law for a dealer to sell or lease any new vehicles in dealer inventory covered by this notification until the vehicle has been repaired. Once the remedy is available, the vehicles will be flagged as “OPEN” and Work
Instructions will be available in NetStar VMI and Xentry Portal. Once the repair is complete, the vehicle may be sold or leased. Loaner and demonstrator vehicles may continue to be driven, but must not be retailed until repaired. As a matter of normal service process, please check for other repair measures which might be applicable to the vehicle(s). Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent new vehicles covered by this notification until the vehicle has been repaired.
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 Mercedes-Benz dealer, 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.

Chronology of Defect/Noncompliance Determination Supplement for ODI 24-00855-30502-10
In March 2022, MBAG initiated an investigation of field reports alleging that certain GLE/GLS (167 platform) vehicles stalled while driving.
MBAG began its analysis by conducting a detailed review of field data and vehicle diagnostic information. These analyses identified some abnormalities that occurred during automatic transmission shifting from 7th to 6th gear. Based on data and information available at that time, MBAG could not connect the reported engine stalling incidents to the shifting abnormalities and did not identify any systemic failure.
From mid-2022 through 2023, MBAG retrieved vehicles from the field whose owners had reported similar stalling incidents and installed data logger hardware for further analysis and testing and attempted to reproduce the reported stalling phenomenon.
In parallel, MBAG developed an advanced diagnostic software feature for workshop technicians to gather and analyze additional data from vehicles with reported stalling incidents and distributed this new diagnosis feature to its service partners.
In May 2023, MBAG succeeded in duplicating the described issue on a single vehicle and record relevant data with an installed data logger. MBAG used that result and related findings as the basis for further in-depth testing, investigations, and analysis of potential failure mechanisms. MBAG’s investigation of the complex and multi-factored phenomenon continued through the end of 2023 and early 2024. Extensive analysis was required to determine the combination of multiple conditions and other factors necessary to allow stalling to occur. MBAG also compared its testing analyses and hypotheses with the additional diagnostic data collected from the field by its service partners using the diagnostic feature developed for this investigation.
These analyses further determined that the reported stalling could only occur in certain GLE/GLS vehicles equipped with a certain 6-cylinder gasoline engine and a certain 9-speed automatic transmission. Using this information, MBAG was able to determine the potentially affected vehicle population.
On February 9, 2024, MBAG determined that a potential safety risk in the identified vehicle population could not be ruled out and decided to conduct a recall.
MBAG is currently aware of 261 field reports received between December 3, 2019 and February 6, 2024 and 730 warranty claims received between May 6, 2019 and December 5, 2023 regarding this topic. MBAG is aware of no other information (such as the numbers of deaths and/or injuries) related to this defect in the USA.

Country : NR Chronology :
In March 2022, MBAG initiated an investigation of field reports alleging that certain GLE/GLS (167 platform) vehicles stalled while driving.
MBAG began its analysis by conducting a detailed review of field data and vehicle diagnostic information. These analyses identified some abnormalities that occurred during automatic transmission shifting from 7th to 6th gear. Based on data and information available at that time, MBAG could not connect the reported engine stalling incidents to the shifting abnormalities and did not identify any systemic failure.
From mid-2022 through 2023, MBAG retrieved vehicles from the field whose owners had reported similar stalling incidents and installed data logger hardware for further analysis and testing and attempted to reproduce the reported stalling phenomenon.
In parallel, MBAG developed an advanced diagnostic software feature for workshop technicians to gather and analyze additional data from vehicles with reported stalling incidents and distributed this new diagnosis feature to its service partners.
In May 2023, MBAG succeeded in duplicating the described issue on a single vehicle and record relevant data with an installed data logger. MBAG used that result and related findings as the basis for further in-depth testing, investigations, and analysis of potential failure mechanisms. MBAG’s investigation of the complex and multi-factored phenomenon continued through the end of 2023 and early 2024. Extensive analysis was required to determine the combination of multiple conditions and other factors necessary to allow stalling to occur. MBAG also compared its testing analyses and hypotheses with the additional diagnostic data collected from the field by its service partners using the diagnostic feature developed for this investigation.

This is to notify you of the Recall Campaign Launch to update the transmission control unit software in 104,851 Model Year (“MY”) 2020-2023
GLE/GLS (167 platform) vehicles. The recall campaign will be visible on the www.NHTSA.gov website and may generate questions from
customers. Affected VINs will be flagged in VMI as “OPEN” on March 15, 2024.
Background
Issue
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that
on certain MY 2020–2023 GLE/GLS (167 platform) vehicles equipped with the 6-cylinder gasoline
engine and 9-speed transmission, the transmission control unit software might not meet current
production specifications. If a downshift of the transmission from 7th to 6th gear is not fully
completed during a simultaneous slight braking maneuver of the vehicle, and additional conditions
exist (e.g. aborted shift operation, low transmission oil temperature, simultaneous recuperation by
the 48V starter-alternator), the engine might stall. In that event, the vehicle would lose propulsion
which could increase the risk of a crash. When the vehicle comes to a standstill the engine can be
restarted. This occurrence does not affect the functionality of the vehicle’s steering and braking
systems.
What We’re Doing MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will update the
transmission control unit software on the potentially affected vehicles.
Parts The remedy is available and can be performed.

Country : NR Chronology :
In March 2022, MBAG initiated an investigation of field reports alleging that certain GLE/GLS (167 platform) vehicles stalled while driving.
MBAG began its analysis by conducting a detailed review of field data and vehicle diagnostic information. These analyses identified some abnormalities that occurred during automatic transmission shifting from 7th to 6th gear. Based on data and information available at that time, MBAG could not connect the reported engine stalling incidents to the shifting abnormalities and did not identify any systemic failure.
From mid-2022 through 2023, MBAG retrieved vehicles from the field whose owners had reported similar stalling incidents and installed data logger hardware for further analysis and testing and attempted to reproduce the reported stalling phenomenon.
In parallel, MBAG developed an advanced diagnostic software feature for workshop technicians to gather and analyze additional data from vehicles with reported stalling incidents and distributed this new diagnosis feature to its service partners.
In May 2023, MBAG succeeded in duplicating the described issue on a single vehicle and record relevant data with an installed data logger. MBAG used that result and related findings as the basis for further in-depth testing, investigations, and analysis of potential failure mechanisms. MBAG’s investigation of the complex and multi-factored phenomenon continued through the end of 2023 and early 2024.
