The recall population was determined through production records. For vehicles outside of the recall population, the front, rear and fixed side window bonding meets specifications. Production Dates : SEP 12, 2023 – SEP 20, 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 GLC (254 platform) vehicles, the front, rear and fixed side window bonding might not meet specifications. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Insufficient adhesion for the stationary front, rear, and side windows cannot be excluded. This might lead to a separation of the windows from the vehicle which could increase the risk of a crash for following traffic. In addition, if a crash resulting in frontal passenger airbag deployment were to occur, the airbag might not be supported by the windshield as intended which could increase the risk of injury for the vehicle occupant. Description of the Cause : Due to a production deviation at a supplier, certain barrels could have been filled with an incorrect adhesive that might not meet current specifications. Identification of Any Warning Before the issue occurs, the driver will not receive a warning due to the nature of the failure mechanism.

As an immediate reaction, MBAG analyzed the adhesive and concluded that the batch delivered did not fulfil specifications. Up until beginning of October, 2023, MBAG and its supplier identified the barrel labelling process as the root cause and could therefore determine the affected batch and subsequently identify the potentially affected vehicle population. In parallel, MBAG started various analyses in order to determine the characteristics of the adhesive which had erroneously been filled into the affected barrels. On this basis, further investigations were performed to check the consequences of the issue. On October 27, 2023, 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 related to this defect in the USA. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will replace the affected windows 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.
