Dear Mercedes-Benz Owner:
This notice is being sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has decided that a defect which relates to motor
vehicle safety exists in certain model year 2020- 2021 GLE and GLS vehicles. Our records indicate that your vehicle is included
in the affected population.
~
What i: the i::ue?
In certain MY 2020-2021 GLE-Class and GLS-Class vehicles, the air conditioning drain hoses might be
incorrectly installed in the vehicle. In this case, condensation water from the air conditioning might enter the
passenger compartment. If a significant volume of condensation water enters the driver and passenger side
footwells, it is possible that corrosion and/ or short circuits to the electrical components installed in this area
could occur, which could increase the risk of fire. In addit ion, the performance of other features of the vehicle
could be affected. For example, the automatic emergency call (eCall) might not be available, the vehicle might
not be able to be unlocked and/ or started; and the engine limp-home mode might be activated during driving.
The impact on these features could increase the risk of injury or a crash. Vehicle occupants might observe wet
carpets in the front footwells, and fogged windows.
What will your Mercedes-Benz Dealership do?
An authorized Mercedes-Benz dealership will inspect and reinstall the air condit ioning drain hoses, if necessary.
This vehiele repair will be provided at no eost to you. While the minimum repair time can be less than one
hour, your dealership can provide you with a better estimate of the overall time for this service visit. As a
matter of normal service process, an authorized Mercedes-Benz dealer will also check for other repair
measures which might be applicable to your vehicle and this may increase the required working t ime. You will
not be charged for other service or repairs unless so requested.

Description of the Defect : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Bez vehicles, has determined that on certain Model Year (“MY”) 2020-2021 GLE and GLS vehicles (167 platform), the air conditioning drain hoses might be incorrectly installed in the vehicle. In this case, condensation water from the air conditioning might enter the passenger compartment.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If a significant volume of condensation water enters the driver and passenger side footwells, it might cause corrosion and/or short circuits to the electrical components installed in this area, which could increase the risk of fire. In The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-177 Page 4 addition, the performance of other features of the vehicle could be affected. For example, the automatic emergency call (eCall) might not be available, the vehicle might not be able to be unlocked and/or started; and the engine limp- home mode might be activated during driving, which could increase the risk of injury or a crash.
Description of the Cause : Due to a deviation in the assembly process, the air conditioning drain hoses might not have been installed according to current production specifications. As a result, the tightness of the connection cannot be ensured. Identification of Any Warning
that can Occur : When the issue occurs, the customer might observe wet carpets in the front footwells and fogged windows.

Country : NR Chronology :
In August 2021, MBAG began an initial investigation of field reports from GLE and GLS vehicles (167 platform) describing varying instances in which customers described water ingress into the passenger compartment.
These subject vehicles were produced outside the production date range of the prior recall measures 19V587 and 21V288.
Between September and December 2021, MBAG examined the affected vehicles and reviewed production records, seeking to identify a cause of the reported issues. In parallel, MBAG reviewed the production facility and relevant vehicle assembly processes, seeking potential factors that might lead to the observed issues with the affected vehicles.
In February 2022, MBAG commenced a further investigation based on the results and findings of its review and updated field reports and analyses. From March to May 2022, MBAG conducted a detailed analysis of field data and reviewed related production records, and a plant rework campaign was issued based on the then-assumed The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-177

failure mechanism. From June 2022 onwards, further cases that occurred in the field required re-evaluation of the failure mechanism and influencing factors. These intensive analyses that were conducted together with the vehicle assembly plant continued throughout the year 2022, while the field situation was constantly monitored and new information was continuously included in the analysis process. In February 2023, final alignments regarding failure mechanism, influencing factors and definition of potentially affected vehicles were conducted. It was determined that condensation water from the air condition might enter the passenger compartment due to incorrect installation of the drain hoses during vehicle assembly.On March 10, 2023, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall. MBAG is currently aware of 58 field reports in the U.S. received from August 12, 2019 to January 3, 2023. MBAG is not aware of any reported crashes, injuries.
Description of Remedy :
Description of Remedy Program : An authorized Mercedes-Benz dealership will check the air conditioning
drain hoses and correct their installation, 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 could have been previously subject to the condition described.
How Remedy Component Differs from Recalled Component :
Air conditioning drain hoses installed according to current production specifications.
Remedy Part:
A 167 832 36 00 – A/C drain hose Identify How/When Recall Condition was Corrected in Production : A change in the production process due to the introduction of special checks and documentation during the installation of the A/C drain hoses ensured that this issue would not occur after February 3, 2021. Dedicated training for production personnel were made mandatory and implemented accordingly. Recall Schedule :
Description of Recall Schedule : Dealers will be notified of the pending voluntary recall campaign on
March 24, 2023. Owners will be notified of the voluntary
recall campaign on or before May 16, 2023. A copy of all communications will be provided when available.
