What's wrong?
The sunroof control unit on the 2020 Mercedes-Benz Gls 580 is the software-controlled module that tells the glass roof when to open, stop, reverse, or close. It is part of the power-operated roof system, so its job is to respond only under the conditions allowed by the vehicle controls and federal power window rules.
On affected vehicles, the software allowed the sunroof to close automatically when car wash mode was activated through the central display or center-console touchpad. Mercedes-Benz traced the issue to a deviation in the software development process. That left some vehicles without the corrected software that blocks this car wash mode closing behavior.
There is no warning sign before failure. The driver does not get a message or light because the issue is built into how the sunroof software responds to car wash mode, not a part that wears out or gradually changes behavior.

What's the safety risk?
An unexpectedly closing sunroof can injure an occupant in the opening. There is no warning sign before an unexpected closure, so keep hands and heads clear and schedule the software update soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2020 Mercedes-Benz Gls 580 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free sunroof-control-unit software update that stops the sunroof from closing unexpectedly in car wash mode.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 23V733 when you call.
- Avoid using car wash mode until the software update is complete, and keep hands and passengers clear of the sunroof when it moves.
What happens at the repair
At the dealer, a Mercedes-Benz technician updates the sunroof control unit software so car wash mode no longer allows the sunroof to close unexpectedly. The software update, parts, and labor are free under the recall. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain covered under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
