VIN Range 1 : Begin : NR End : NR Not sequential Description of Noncompliance : Description of the Noncompliance : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2019-2022 GLC (253 platform) vehicles, the headlamp adjustment might not meet current production specifications. FMVSS 1 : 108 – Lamps, reflective devices, and assoc. Equipment FMVSS 2 : NR
Description of the Safety Risk : In this case, the headlamps might be adjusted slightly too high. As a result, FMVSS 108 S.10.18 might not be fulfilled.
The headlamps installed in the US might exceed the range specified by FMVSS 108 by approximately 0.15%.
A headlamp adjustment that is outside of the FMVSS 108 specifications has the potential to create glare for oncoming traffic, which may increase the risk of a crash.
Description of the Cause : Due to a deviation in the headlamp adjustment tool in the vehicle production plant, certain headlamp adjustments might not meet current production specifications. The issue described in not caused by a supplier. Identification of Any Warning
that can Occur : The driver will not receive a warning due to the nature of the failure mechanism.

Country : NR Chronology :
In late 2021, IIHS conducted a rating of certain GLC (253 platform) vehicles, including their headlamp adjustments. The review of the rating results concluded that those headlamps might have been adjusted at an angle that exceeded MBAG’s current production specification. The reported deviation was within the tolerance limits specified by FMVSS 108. Nonetheless, MBAG conducted plant actions to check headlamp adjustments on potentially affected vehicles and ensure headlamp adjustments were completed and consistent with current production specifications. Additionally at this time, MBAG readjusted the calibration process to avoid potential headlamp adjustment deviations in the production process. These process changes occurred in January 2022. In July 2022, MBAG’s vehicle audit process determined that headlamps in a GLC vehicle, built prior to the internal production adjustments, were set slightly above MBAG’s internal production specifications (but still within FMVSS specifications). Based on that finding, MBAG initiated an investigation of the headlamp adjustments in GLC vehicles produced at two different plants. MBAG conducted additional testing and analyses through the second half of 2022 until the beginning of 2023 to determine whether production lines from the two identified plants showed deviations in the headlamp adjustments. These analyses ultimately determined in mid-2023 that only vehicles with headlamps adjusted on two production lines from a single plant might not meet MBAG’s current production specifications. In the second half of 2023 and into January 2024, MBAG conducted further investigations to determine the cause of the incorrect adjustments and the extent to which the adjustment might potentially deviate from MBAG´s production specifications. As part of that review, MBAG found that, in some instances, the headlamp angle adjustment could also slightly exceed the tolerance requirements of FMVSS 108. Please see attached chronology update.
