Estimated percentage with defect : 100 %
Vehicle Information :
Vehicle 1 : 2024-2024 Mercedes-Benz GLE 450 e
Vehicle Type : LIGHT VEHICLES

Power Train : HYBRID ELECTRIC
Descriptive Information : 2,770 vehicles. The recall population was determined through production records.
For vehicles outside of the recall population, the installed ESP control unit software is
according to current production specifications.
Production Dates : JAN 06, 2023 – OCT 27, 2023
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”) 2024 GLE Plug-in-Hybrid (167
platform) vehicles, under specific conditions (such as electric driving under
wet weather conditions), the required input force on the brake pedal might be
increased.
FMVSS 1 : NR
FMVSS 2 : NR
Description of the Safety Risk : If the driver does not apply the increased input force to the brake pedal, the
braking distance might be temporarily extended, which could increase the
risk of a crash. If the required input force is applied, then a sufficient braking
effect is achieved at all times in accordance with FMVSS 135.
Description of the Cause : Due to a deviation in the development process, the brake force boost by the
ESP control unit might not meet current production software specifications.
The issue described is not caused by a supplier.

Chronology :
In February 2022, MBAG investigated isolated field reports, from outside the US, alleging that the braking
system in certain GLE vehicles did not respond as expected during operation.
MBAG began its analysis by conducting a detailed review of field data and examining vehicles identified in the
field reports. At that time, MBAG was unable to identify a failure mechanism that might result in the reported
issue.
MBAG conducted extensive further investigations through April 2023, including simulations of field and
environmental conditions during endurance and wind tunnel tests that it suspected could trigger the reported
failure. As part of these analyses and tests, MBAG explored whether factors such as weather conditions, the
driving profile of the vehicle and wear to the braking system might contribute to the alleged issues. Due to the
complexity and numerous environmental influences that contribute to the issue, MBAG was unable to
reproduce the alleged phenomenon during this investigation.
MBAG launched a Black Belt project and team to analyze other processes or factors that may have contributed
to the alleged occurrences. This team reviewed available data and hypothesized that, in certain driving
conditions, the ESP control unit might not provide sufficient brake support. During the next several months,
MBAG validated this hypothesis using technical reviews as well as analyses of field data from newly identified
reports of the alleged issue from outside the US.
Part 573 Safety Recall Report 23V-807 Page 3
The information contained in this report was submitted pursuant to 49 CFR §573
In September and October 2023, MBAG analyzed production records pertaining to this ESP control unit
software version to identify the population of potentially affected vehicles in the field. Additionally, MBAG
initiated a plant rework action to update the ESP control unit software in potentially affected vehicles that
remained in MBAG’s control.
On November 24, 2023, MBAG determined that a potential safety risk could not be ruled out and decided to
conduct a recall.
Please see chronology supplement.
Description of Remedy :
Description of Remedy Program : An authorized Mercedes-Benz dealer will update the ESP control unit
software in 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 :
ESP control unit software is according to current production specification.
Remedy parts: A2139025727 (ESP Software)
Identify How/When Recall Condition
was Corrected in Production :
The introduction of a new ESP software ensures that this issue can no
longer occur from October 30, 2023 onwards.
Recall Schedule :
Description of Recall Schedule : Dealers will be notified of the pending voluntary recall campaign on
December 8, 2023. Owners will be notified of the voluntary recall
campaign on or before January 30, 2024. A copy of all communications
will be provided when available.

Background
Issue
Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY24 GLE Plug-in-Hybrid (167 platform) vehicles, the brake force boost by the ESP control unit might not meet current production specifications. Under specific conditions, such as driving in full electric mode during wet weather conditions, the required brake pedal force might be increased. If the driver does not apply the increased brake pedal force, the braking distance might be temporarily extended, which could increase the risk of a crash.
What We’re Doing
MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will update the ESP control unit software in the affected vehicles. Parts Remedy is not available at this time.

Interim Letter: Update ESP Control Unit Software
NHTSA Recall ID: 23V807
13470 International Parkway
Jacksonville, FL 32218
January, 2024
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 2024 GLE Plug-in-Hybrid vehicles. Our records indicate that your
vehicle is included in the affected population.
What is the issue?
Due to a software error in the electronic stability program (ESP) control unit, the braking force required to
stop the vehicle while driving in electric mode and in certain conditions (such as wet weather), may
increase. This could require an extended distance to stop the vehicle, which can increase the risk of a
crash.
Unfortunately, the remedy is not yet available. We are working to obtain the necessary parts and/or
software to address this important safety recall as quickly as possible. When the remedy becomes
available, we will send you another letter informing you to schedule an appointment with an authorized
Mercedes-Benz dealer to have your vehicle repaired, at no cost to you.
Should you have any concerns or questions regarding your vehicle before you receive the next letter when the
remedy becomes available, please contact 1-(800) FOR-MERCEDES (1-800-367-6372).
