Mercedes-Benz is recalling nearly 125,000 coupe and sedan models to address a potential defect with their sunroof panels that may allow them to detach from the vehicle while in motion. Broadly speaking, the campaign covers various 2001-2011 C-Class, CLK, E-Class, and CLS models — including AMG variants where applicable. Per Mercedes, the vehicles included in the campaign may have shipped with inadequate bonding between the glass panel and sliding roof frame, which may allow them to separate.
“Due to a production deviation at a supplier, glass panels might have been bonded without proper application and/or ventilation of the primer (bonding agent),” the automaker said in its defect notice. “The correct usage of the primer is necessary in order to ensure the specified strength of the bonded joint. In this case, the adhesion of the bond might deteriorate gradually over time. Therefore, the specified durability requirements of the bond would not be guaranteed. As a consequence, a separation of the glass panel from the vehicle cannot be ruled out. This could increase the risk of a potential accident and/or injury for other road users.”
Here is the full list of models covered by the campaign, taken directly from the Mercedes-Benz recall notice:
- C230/2002-2007

‘Benz says that owners may notice increased wind noise or visible gaps between the panel and mechanism as it begins to fail. The company will reimburse those owners who have already had this problem addressed outside of the factory warranty and new parts will be provided for those whose vehicles show signs of degraded bonding. Look for notices to be distributed by the end of February, 2023.
