Mercedes-Benz Sunroof Recall Affects 134,000 Vehicles

2011 Mercedes-Benz AMG CLS63.

Mercedes-Benz has recalled more than 134,000 vehicles because the sunroof glass may not be secure and could detach from the vehicles.

Mercedes said the bonding between the glass sunroof panel and the sliding roof frame might not meet specifications.

The Mercedes sunroof recall is an expansion of a December 2019 sunroof recall.

These 2001-2011 vehicles are affected by the expanded sunroof recall.

"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 correct usage of the primer is necessary in order to ensure the specified strength of the bonded joint," Mercedes-Benz said.

Mercedes opened an investigation in December 2017 based on sunroof reports outside the U.S. Owners said the sliding roof panels detached from the vehicles, although no damage or injuries were reported.

Mercedes, the supplier and an outside lab analyzed the sunroofs and learned how the supplier had changed the process of the primer application several times, including having changed the drying time for the bonding agent.

In November 2019, the automaker determined the supplier reduced the drying time of the primer to two minutes from more than five minutes.

Mercedes ordered the December 2019 recall but vehicles continued to suffer from detached sunroof panels.

A driver may get advance notice before the sunroof flies away if they see loose components or hears too much wind noise from the sunroof.

More than 10,000 of the recalled Mercedes vehicles are in Canada.

Mercedes expects to mail sunroof recall letters Feb. 21, and dealerships will replace the sunroof panels if necessary.
