The large recall covers more than two dozen vehicles from C-Class, CLK-Class, CLS-Class and E-Class model lines. The automaker said the bonding between the glass panel and the sliding room frame might not meet specifications and could lead to sunroofs detaching.

Owners who paid for repairs for the issue will be able to seek reimbursements from Daimler. A Mercedes-Benz USA spokesman said on Saturday he did not have a worldwide vehicle total for the recall.

Dealers will inspect the glass panel bonding and replace the sliding roof if necessary, the company said.

Last month, Mercedes-Benz USA agreed to a US$20 million civil penalty over its handling of US vehicle recalls after a year-long US government investigation into 1.4 million recalled vehicles.

Under the terms of the settlement, the automaker will pay US$13 million and faces another US$7 million fine if it does not comply with the agreement.

The US National Highway Traffic Safety Administration said the company failed to notify owners in a timely fashion in some recalls, did not submit all reports and did not launch at least two recalls in a timely fashion.
