Replace Fuel Pump Delivery Module NHTSA Recall ID: 23V445
August 2023
Dear Mercedes-Benz Owner: This notice is 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 (“MY”) 2021-2023 C-Class, E-Class, CLS, S-Class, SL, GT, GLC, GLE, GLS and G-Class vehicles. Our records indicate that your vehicle is included in the affected population.
What is the concern?
The fuel pump impeller might not meet current specifications regarding its material characteristics. As a consequence, the impeller might deform and contact the fuel pump housing, resulting in mechanical resistance on the impeller. This could cause the fuel pump to stop operating. As a result, the vehicle could lose drive power, which could increase the risk of crash or injury. Before the fuel pump is switched off, the
� driver may be made aware of a malfunction by a warning message in the instrument cluster and might notice a roughly running engine. Unfortunately, the remedy is not yet available. When the replacement fuel pump delivery module becomes available, we will send you another letter informing you to schedule an appointment with an authorized Mercedes-Benz dealer to have this vehicle repair provided at no cost to you.
We apologize for any inconvenience this may have caused and look forward to taking care of this important safety issue immediately.

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 Model Year (“MY”) 2021-2023 GLE/GLS (167 platform), C-Class (205, 206 platform), E-Class (213 platform), S-Class (223 platform), SL (232 platform), E-Class Coupe/Convertible (238 platform), GLC (253 platform), CLS (257 platform), AMG GT 4-doors Coupe (290 platform) and G-Class (463 platform) vehicles, the fuel pump impeller might not meet current specifications in regards to material characteristics.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : As a consequence, the impeller might deform and therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of crash or injury.
Description of the Cause : Due to a deviation in the production process of a sub-supplier, certain fuel pump impellers might not meet the material requirements and thus certain batches of fuel delivery modules might not meet the durability requirements. Identification of Any Warning
that can Occur : Before the fuel pump is switched off, the driver may be made aware of a malfunction by a warning message in the instrument cluster and might notice the engine running rough.

Address : 29, Yeongni-gil Yeongin-myeon, Asan-si, Chung Cheong Nam-Do Foreign States The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-445 Page 14 Country : Korea, Democratic People’s Republic of Chronology :
In the beginning of June 2022, MBAG launched initial investigations based on individual field reports from outside the US alleging inconsistent power delivery. MBAG hypothesized that, the function of the fuel pump might have been impaired without having any initial indications in regards to common influencing factors on the field cases in this relation. In July 2022, MBAG began retrieving fuel pumps from affected vehicles in the field and analyzing them in coordination with the supplier. Over the next several months, MBAG conducted analyses of the material together with the supplier, as well as the production processes at the supplier and its sub-suppliers. Through the end of the year, MBAG conducted numerous and varied tests in coordination with its tier one supplier, including fuel swelling behavior, structural damage and notched impact resistance tests. In December 2022, these intensive analyses and tests identified an irregularity in individual raw material batches used for the suspect fuel pump impellers, sourced from a sub-supplier. Based on that determination, in January 2023, MBAG’s supplier of the suspect fuel pump started investigations to identify the potentially affected vehicle population by tracking the material flow within the multi-supplier chain from the raw material sub- supplier up to the fuel pump manufacturer. At the same time, the fuel pump supplier implemented several changes in its production process, including a replacement of the raw material supplier, changing the injection molding process at the injection molding supplier and implementing more quality controls within the supplier chain. Through May 2023, MBAG and its fuel pump supplier conducted further testing and analyses to identify potential influencing factors and determine potential consequences of material and process anomalies at different steps of the production process. Please see chronology supplement attached. Description of Remedy :
Description of Remedy Program : An authorized Mercedes-Benz dealership will replace the fuel delivery
module on the affected vehicles.
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 How Remedy Component Differs from Recalled Component : Fuel pump impellers that meet the material requirements.

FMVSS 1 : NR The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-445 Page 11 FMVSS 2 : NR
Description of the Safety Risk : As a consequence, the impeller might deform and therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of crash or injury.
Description of the Cause : Due to a deviation in the production process of a sub-supplier, certain fuel pump impellers might not meet the material requirements and thus certain batches of fuel delivery modules might not meet the durability requirements. Identification of Any Warning
that can Occur : Before the fuel pump is switched off, the driver may be made aware of a malfunction by a warning message in the instrument cluster and might notice the engine running rough.

Country : Korea, Democratic People’s Republic of Chronology :
In the beginning of June 2022, MBAG launched initial investigations based on individual field reports from outside the US alleging inconsistent power delivery. MBAG hypothesized that, the function of the fuel pump might have been impaired without having any initial indications in regards to common influencing factors on the field cases in this relation. In July 2022, MBAG began retrieving fuel pumps from affected vehicles in the field and analyzing them in coordination with the supplier. Over the next several months, MBAG conducted analyses of the material together with the supplier, as well as the production processes at the supplier and its sub-suppliers. Through the end of the year, MBAG conducted numerous and varied tests in coordination with its tier one supplier, including fuel swelling behavior, structural damage and notched impact resistance tests. In December 2022, these intensive analyses and tests identified an irregularity in individual raw material batches used for the suspect fuel pump impellers, sourced from a sub-supplier. Based on that determination, in January 2023, MBAG’s supplier of the suspect fuel pump started investigations to identify the potentially affected vehicle population by tracking the material flow within the multi-supplier chain from the raw material sub- supplier up to the fuel pump manufacturer. At the same time, the fuel pump supplier implemented several changes in its production process, including a replacement of the raw material supplier, changing the injection molding process at the injection molding supplier and implementing more quality controls within the supplier chain. Through May 2023, MBAG and its fuel pump supplier conducted further testing and analyses to identify potential influencing factors and determine potential consequences of material and process anomalies at different steps of the production process.

Based on that determination, in January 2023, MBAG’s supplier of the suspect fuel pump started investigations to identify the potentially affected vehicle population by tracking the material flow within the multi-supplier chain from the raw material sub- supplier up to the fuel pump manufacturer. At the same time, the fuel pump supplier implemented several changes in its production process, including a replacement of the raw material supplier, changing the injection molding process at the injection molding supplier and implementing more quality controls within the supplier chain. Through May 2023, MBAG and its fuel pump supplier conducted further testing and analyses to identify potential influencing factors and determine potential consequences of material and process anomalies at different steps of the production process.

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 Model Year (“MY”) 2021-2023 GLE/GLS (167 platform), C-Class (205, 206 platform), E-Class (213 platform), S-Class (223 platform), SL (232 platform), E-Class Coupe/Convertible (238 platform), GLC (253 platform), CLS (257 platform), AMG GT 4-doors Coupe (290 platform) and G-Class (463 platform) vehicles, the fuel pump impeller might not meet current specifications in regards to material characteristics.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : As a consequence, the impeller might deform and therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of crash or injury.
Description of the Cause : Due to a deviation in the production process of a sub-supplier, certain fuel pump impellers might not meet the material requirements and thus certain batches of fuel delivery modules might not meet the durability requirements. Identification of Any Warning
that can Occur : Before the fuel pump is switched off, the driver may be made aware of a malfunction by a warning message in the instrument cluster and might notice the engine running rough.

Country : Korea, Democratic People’s Republic of Chronology :
In the beginning of June 2022, MBAG launched initial investigations based on individual field reports from The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-445 Page 14 outside the US alleging inconsistent power delivery. MBAG hypothesized that, the function of the fuel pump might have been impaired without having any initial indications in regards to common influencing factors on the field cases in this relation. In July 2022, MBAG began retrieving fuel pumps from affected vehicles in the field and analyzing them in coordination with the supplier. Over the next several months, MBAG conducted analyses of the material together with the supplier, as well as the production processes at the supplier and its sub-suppliers. Through the end of the year, MBAG conducted numerous and varied tests in coordination with its tier one supplier, including fuel swelling behavior, structural damage and notched impact resistance tests. In December 2022, these intensive analyses and tests identified an irregularity in individual raw material batches used for the suspect fuel pump impellers, sourced from a sub-supplier. Based on that determination, in January 2023, MBAG’s supplier of the suspect fuel pump started investigations to identify the potentially affected vehicle population by tracking the material flow within the multi-supplier chain from the raw material sub- supplier up to the fuel pump manufacturer. At the same time, the fuel pump supplier implemented several changes in its production process, including a replacement of the raw material supplier, changing the injection molding process at the injection molding supplier and implementing more quality controls within the supplier chain. Through May 2023, MBAG and its fuel pump supplier conducted further testing and analyses to identify potential influencing factors and determine potential consequences of material and process anomalies at different steps of the production process.

Description of the Defect : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2021-2023 GLE/GLS (167 platform), C-Class (205, 206 platform), E-Class (213 platform), S-Class (223 platform), SL (232 platform), E-Class Coupe/Convertible (238 platform), GLC (253, 254 platform), CLS (257 platform), AMG GT 4-doors Coupe (290 platform) and G-Class (463 platform) vehicles, the fuel pump impeller might not meet current specifications in regards to material characteristics.
FMVSS 1 : NR The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-445 Page 11 FMVSS 2 : NR
Description of the Safety Risk : As a consequence, the impeller might deform and therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of crash or injury.
Description of the Cause : Due to a deviation in the production process of a sub-supplier, certain fuel pump impellers might not meet the material requirements and thus certain batches of fuel delivery modules might not meet the durability requirements. Identification of Any Warning
that can Occur : Before the fuel pump is switched off, the driver may be made aware of a malfunction by a warning message in the instrument cluster and might notice the engine running rough.

Address : 29, Yeongni-gil Yeongin-myeon, Asan-si, Chung Cheong Nam-Do Foreign States
Country : Korea, Democratic People’s Republic of Chronology :
In the beginning of June 2022, MBAG launched initial investigations based on individual field reports from outside the US alleging inconsistent power delivery. MBAG hypothesized that, the function of the fuel pump might have been impaired without having any initial indications in regards to common influencing factors on the field cases in this relation. In July 2022, MBAG began retrieving fuel pumps from affected vehicles in the field and analyzing them in coordination with the supplier. Over the next several months, MBAG conducted analyses of the material together with the supplier, as well as the production processes at the supplier and its sub-suppliers. Through the end of the year, MBAG conducted numerous and varied tests in coordination with its tier one supplier, including fuel swelling behavior, structural damage and notched impact resistance tests. In December 2022, these intensive analyses and tests identified an irregularity in individual raw material batches used for the suspect fuel pump impellers, sourced from a sub-supplier. Based on that determination, in January 2023, MBAG’s supplier of the suspect fuel pump started investigations to identify the potentially affected vehicle population by tracking the material flow within the multi-supplier chain from the raw material sub- supplier up to the fuel pump manufacturer. At the same time, the fuel pump supplier implemented several changes in its production process, including a replacement of the raw material supplier, changing the injection molding process at the injection molding supplier and implementing more quality controls within the supplier chain. Through May 2023, MBAG and its fuel pump supplier conducted further testing and analyses to identify potential influencing factors and determine potential consequences of material and process anomalies at different steps of the production process.

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 Model Year (“MY”) 2021-2023 GLE/GLS (167 platform), C-Class (205, 206 platform), E-Class (213 platform), S-Class (223 platform), SL (232 platform), E-Class Coupe/Convertible (238 platform), GLC (253 platform), CLS (257 platform), AMG GT 4-doors Coupe (290 platform) and G-Class (463 platform) vehicles, the fuel pump impeller might not meet current specifications in regards to material characteristics.
FMVSS 1 : NR The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-445 Page 11 FMVSS 2 : NR
Description of the Safety Risk : As a consequence, the impeller might deform and therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of crash or injury.
Description of the Cause : Due to a deviation in the production process of a sub-supplier, certain fuel pump impellers might not meet the material requirements and thus certain batches of fuel delivery modules might not meet the durability requirements. Identification of Any Warning
that can Occur : Before the fuel pump is switched off, the driver may be made aware of a malfunction by a warning message in the instrument cluster and might notice the engine running rough.

Country : Korea, Democratic People’s Republic of Chronology :
In the beginning of June 2022, MBAG launched initial investigations based on individual field reports from outside the US alleging inconsistent power delivery. MBAG hypothesized that, the function of the fuel pump might have been impaired without having any initial indications in regards to common influencing factors on the field cases in this relation. In July 2022, MBAG began retrieving fuel pumps from affected vehicles in the field and analyzing them in coordination with the supplier. Over the next several months, MBAG conducted analyses of the material together with the supplier, as well as the production processes at the supplier and its sub-suppliers. Through the end of the year, MBAG conducted numerous and varied tests in coordination with its tier one supplier, including fuel swelling behavior, structural damage and notched impact resistance tests. In December 2022, these intensive analyses and tests identified an irregularity in individual raw material batches used for the suspect fuel pump impellers, sourced from a sub-supplier. Based on that determination, in January 2023, MBAG’s supplier of the suspect fuel pump started investigations to identify the potentially affected vehicle population by tracking the material flow within the multi-supplier chain from the raw material sub- supplier up to the fuel pump manufacturer. At the same time, the fuel pump supplier implemented several changes in its production process, including a replacement of the raw material supplier, changing the injection molding process at the injection molding supplier and implementing more quality controls within the supplier chain. Through May 2023, MBAG and its fuel pump supplier conducted further testing and analyses to identify potential influencing factors and determine potential consequences of material and process anomalies at different steps of the production process.

switched off, the driver may be made aware of a malfunction by a warning message in the instrument cluster
and might notice a roughly running engine.
What will your Mercedes-Benz Dealer do?
An authorized Mercedes-Benz dealer will replace the fuel pump delivery module. This vehicle repair will
be provided at no cost to you. While the repair t ime can be between 1 to 6 hours, your dealer can
provide you with a better estimate of the overall time for this visit. As a matter of normal service process,
an authorized Mercedes-Benz dealer will also check for other repair measures that might be applicable to
your vehicle, which may increase the required working time. You will not be charged for other services or
repairs unless so requested.

FMVSS 1 : NR The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-445 Page 11 FMVSS 2 : NR
Description of the Safety Risk : As a consequence, the impeller might deform and therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of crash or injury.
Description of the Cause : Due to a deviation in the production process of a sub-supplier, certain fuel pump impellers might not meet the material requirements and thus certain batches of fuel delivery modules might not meet the durability requirements. Identification of Any Warning
that can Occur : Before the fuel pump is switched off, the driver may be made aware of a malfunction by a warning message in the instrument cluster and might notice the engine running rough.

Address : 29, Yeongni-gil Yeongin-myeon, Asan-si, Chung Cheong Nam-Do Foreign States
Country : Korea, Democratic People’s Republic of Chronology :
In the beginning of June 2022, MBAG launched initial investigations based on individual field reports from outside the US alleging inconsistent power delivery. MBAG hypothesized that, the function of the fuel pump might have been impaired without having any initial indications in regards to common influencing factors on the field cases in this relation. In July 2022, MBAG began retrieving fuel pumps from affected vehicles in the field and analyzing them in coordination with the supplier. Over the next several months, MBAG conducted analyses of the material together with the supplier, as well as the production processes at the supplier and its sub-suppliers. Through the end of the year, MBAG conducted numerous and varied tests in coordination with its tier one supplier, including fuel swelling behavior, structural damage and notched impact resistance tests. In December 2022, these intensive analyses and tests identified an irregularity in individual raw material batches used for the suspect fuel pump impellers, sourced from a sub-supplier. Based on that determination, in January 2023, MBAG’s supplier of the suspect fuel pump started investigations to identify the potentially affected vehicle population by tracking the material flow within the multi-supplier chain from the raw material sub- supplier up to the fuel pump manufacturer. At the same time, the fuel pump supplier implemented several changes in its production process, including a replacement of the raw material supplier, changing the injection molding process at the injection molding supplier and implementing more quality controls within the supplier chain. Through May 2023, MBAG and its fuel pump supplier conducted further testing and analyses to identify potential influencing factors and determine potential consequences of material and process anomalies at different steps of the production process.
