Mercedes-Benz USA is recalling a previous recall for fuse boxes, electronic stability control programming and driver’s side seat belt covers, according to documents made public this morning by the National Highway Traffic Safety Administration. First, an incorrect fuse box that was not designed for the vehicle may have been installed. Second, the vehicle’s electronic stability program (ESP) may display an incorrect warning light during an ESP system failure. Third, the driver-side seat belt cover may not be properly installed on the seat belt tensioner, which can cause the seat belt anchor to come loose.
All told ~6700 vehicles are affected. NHTSA recall campaigns are 25V255 or 25V-255, 25V254 or 25V-254, 25V253 or 25V-253.* Planned owner notification dates are not until June 2025.
NHTSA Campaign Number 25V255 – Incorrect Fuse Box
An incorrect fuse box that was not designed for the vehicle may have been installed. Affected are model year 2023-2024 C-Class, S-Class, SL, GLC, EQE SUV, EQE, EQS SUV, and EQS vehicles that were incorrectly repaired under recall 24V-115
“In February 2024, MBAG initiated recall 24V115 (24V-115) to address certain fuses that might not meet production specifications. In mid-March 2025, MBAG was made aware of a field case, from outside the USA, indicating a potential defect on the fuse box.
During the analysis, it was determined that the vehicle had been reworked as part of a recall regarding fuse boxes. Further analysis revealed that it had been equipped with a fuse box not intended for that specific vehicle model.
Thorough analyses of the recall indicated that other workshops had potentially installed incorrect fuse boxes during the recall repair, as well. Through the end of March 2025, MBAG evaluated which vehicles were potentially incorrectly serviced. During the root cause analysis, ambiguities in the parts ordering system were identified and corrected. Additionally, information on the correct use of the parts ordering system was distributed to dealers.
On 11 April 2025, MBAG decided to conduct a recall. MBAG can confirm there are no warranty claims, field or service reports, and other information (such as the numbers of deaths and/or injuries) related to this defect in the US,” Mercedes told NHTSA in the mandatory NHTSA safety recall filing.
NHTSA Campaign Number 25V254 – Electronic Stability Control
“The vehicle’s electronic stability program (ESP) may display an incorrect warning light during an ESP system failure. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 126, “Electronic Stability Control Systems,” and 101, ‘Control and Displays.’ Affected are 2025 model year G 550, G 580, and AMG G 63 vehicles.
“In October 2024, a supplier (Bosch Engineering GmbH) indicated a potential issue regarding the assignment of warning telltales within the ESP control unit software. Immediately, an internal analysis was initiated to assess potential technical implications. In parallel, updated software to correct the issue was developed and introduced into production as an immediate measure in December 2024.
“Through March 2025, further analysis was carried out in collaboration with the supplier to assess potential implications on the vehicles in the field. This included a thorough testing of the specific fault cases and the corresponding warning telltales displayed. Furthermore, a detailed analysis of the relevant guidance to the driver in the operating instructions was performed based on the warning telltales. Additionally, a plant campaign was initiated to rework all vehicles still in possession of MBAG.
“On 11 April 2025, MBAG determined that a potential non-conformity related to the faulty ESP control unit software could not be ruled out and decided to conduct a recall. MBAG can confirm there are no warranty claims, field or service reports, and other information related to this defect in the US,” Mercedes said in the mandatory NHTSA safety recall filing.
NHTSA Campaign Number 25V253 – Seat Belts
“The driver-side seat belt cover may not be properly installed on the seat belt tensioner, which can cause the seat belt anchor to come loose. Affected are some model-year 2022-2025 C 300, and 2023-2024 AMG C 43 vehicles.
“In January 2025, MBAG became aware of a field complaint from outside the US, where a customer alleged that the seat belt loosened while driving. An immediate investigation found that the cover of the driver seat belt’s tensioner was not properly installed. Analyses in February and March 2025 aimed to identify the root cause of this issue. These analyses revealed that the vehicle had undergone plant rework that included the cover, and it was believed that an employee might not have followed the work instructions correctly. Subsequently, MBAG determined the potentially affected vehicle population based on rework data.
“Out of an abundance of caution, on 11 April 2025, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall. MBAG can confirm there are no warranty claims, field or service reports, and other information (such as the numbers of deaths and/or injuries) related to this defect in the US,” Mercedes told NHTSA in the mandatory NHTSA safety recall filing.
