The front roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair.
Mercedes says the adhesion of the front panel to the vehicle body might degrade over time and cause the front panel to partially or fully detach from the vehicle and cause problems for others on the road.
A driver may notice a loose panel or hear more wind noise than normal coming from the sunroof.
Federal safety regulators contacted Mercedes in June 2020 regarding roof panels in front of the panoramic sunroofs which detached on the highways. Mercedes launched an internal investigation and found the wrong adhesive was used to bond the panels during previous repairs.
The automaker learned of more incidents that occurred between 2018-2020 involving claims of cracked or detached panels. Then engineers determined all the vehicles had been through previous repairs to the front roof panels.
The National Highway Traffic Safety Administration opened an investigation in January 2021 for C-Class vehicles that had their front sunroof panels replaced. Investigators determined there were deviations in the repair procedures concerning pre-treatment, cleaning and primer application to bond the panels.
Mercedes-Benz dealers will replace the front roof panels when the recall begins May 14, 2021.
Also included in a separate recall are these 2006-2007 Mercedes models due to bonding problems between the glass sunroof panels and sliding roof frames: C350, C230, C280, CLK350, E320CDI, E350 Wagon, E350, 2006 C55 AMG, CLK500, CLS500, CLS55 AMG, E500 Wagon, E500, E55 AMG, 2007 CLK550, CLS550, CLS63 AMG, E550, E63 AMG and E63 Wagon AMG.
