Replace Stationary Windows

This is to notify you of the Recall Campaign Launch to replace the stationary windows on 7 Model Year (“MY”) 2024 GLC (254 platform) vehicles. The recall campaign will be visible on the www.NHTSA.gov website and may generate questions from customers. Affected VINs will be flagged in VMI as “OPEN” on November 10, 2023.

 

Issue

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2024 GLC (254 platform) vehicles, the stationary front, rear and side window bonding might not meet specifications. Insufficient adhesion 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 front passenger.

 

What We’re Doing

MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will replace the stationary windows on the affected vehicles.

 

Parts

The remedy is available and can be performed.

 

Given this notice, it is a violation of Federal law for a dealer to sell or lease any new vehicles in dealer inventory covered by this notification until the vehicle has been repaired.

Chronology :

Mid-September 2023, MBAG became aware of an irregularity in the production process, during which the adhesive on one window had unexpected material characteristics. 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.
