German carmaker Daimler AG will recall 744,000 of its 2001-2011 Mercedes-Benz vehicles in the US because the sunroof glass panel could detach and pose a hazard.

The recall covers more 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 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 $20m civil penalty over its handling of US vehicle recalls after a year-long US government investigation into 1.4m recalled vehicles.

Under the terms of the settlement, the automaker will pay $13m and faces another $7m 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.
