What's wrong?
The MBUX multimedia system in the affected 2024 Mercedes-Benz E 350, E 450, Cle 300, AMG CLE53, and Cle 450 vehicles runs more than entertainment features. Its headunit software also communicates with the parking control unit, which manages parking assistance functions, including cross-traffic alert and automatic braking while backing out of a parking space.
In this recall, the software synchronization between MBUX and the parking control unit is impaired. That communication error can deactivate certain parking assistance systems without telling the driver. If cross-traffic alert is inactive when another road user is approaching, the vehicle loses the automatic brake intervention that is supposed to help before the driver reacts to visual or audible alerts. That can increase crash risk while exiting a parking space.
There is no warning sign before failure. The driver does not receive a message or alert that the affected parking assistance functions have been deactivated.

What happens at the repair
At the dealer, a Mercedes-Benz technician updates the MBUX multimedia system software and adjusts the parking control unit settings. The software update and labor are free under the recall. Out of pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program, since the involved vehicles remain covered under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
