Mercedes-Benz is recalling 2,976 2014-2020 C300, CLA250, GLC300, and other vehicles because an incorrectly bonded front roof panel between the windshield and panoramic sunroof can detach after a prior repair.

What's wrong?
On affected 2014-2020 Mercedes-Benz vehicles with a panoramic roof, the front roof panel sits between the windshield and the glass roof opening. That panel is part of the roof structure and is held in place with adhesive, so it stays fixed to the body while the vehicle moves through wind, vibration, and temperature changes.
The problem comes from a prior repair to that roof panel. Mercedes-Benz found that some repaired panels were not bonded according to the required workshop process, including cases involving the wrong adhesive or incorrect surface preparation. When the bond is weak, the adhesive grip deteriorates and the panel loosens. If it separates far enough, the front roof panel can detach from the vehicle.
Owners can see the panel partly lifted or separated near the panoramic roof. Another warning sign is excessive wind noise from the sunroof area while driving.
Who's affected?
Spans several Mercedes-Benz and Mercedes-Maybach model lines from 2014-2020, all tied to the panoramic roof and body structure.

What should I do?
- Check your VIN to confirm your 2014-2020 Mercedes-Benz or Mercedes-Maybach model is included in this recall.

- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 23V854 when you call.
