Recall 23V574 covers 880 2023 Mercedes-Benz vehicles with exit-warning software that fails to alert occupants. Repair is free at any franchised Mercedes-Benz dealer.
Mercedes-Benz is recalling 880 2023 E 350, E 450, Cls 450, AMG E53, AMG E63 S, AMG GT43, and AMG GT53 vehicles because a software error can stop the exit warning system from alerting occupants to approaching traffic. When that warning fails before a door opens, the risk of a crash or injury rises; Mercedes-Benz dealers will complete the repair free of charge.

What's wrong?
The exit warning system on these 2023 Mercedes-Benz vehicles is part of Active Blind Spot Assist. It uses multimode radar software, which reads sensor information around the vehicle, to warn occupants when traffic or another road user is approaching from behind before a door is opened.
On affected vehicles, the system was coded with inaccurate parameters. Those settings do not match the intended software specification, so the exit warning system does not give the expected visual or audio warning while the vehicle is parked on a street or roadway. The issue is limited to the exit warning function, not the rest of Active Blind Spot Assist.
There is no warning sign before failure. The missing alert is the failure: an occupant opens the door and does not receive the visual or audio cue that the system is supposed to provide.
Who's affected?
The shared link is the multimode radar software tied to the blind-spot sensor system across the listed Mercedes-Benz cars.

What's the safety risk?
If the exit warning system fails, occupants are not alerted to an approaching vehicle when opening a door, which increases the risk of a crash or injury. There is no warning sign before failure, so use extra care when exiting and schedule the software update. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2023 Mercedes-Benz E 350, AMG GT43, E 450, Cls 450, AMG E53, AMG GT53, or AMG E63 S is included in this recall.
- Contact your nearest franchised Mercedes-Benz dealer to schedule the free exit-warning-system software update that restores audio and visual alerts for approaching vehicles.
- Bring the owner notice if Mercedes-Benz mailed one. If not, reference recall number 23V574 when you call.
- Use extra care when opening doors until the software update is complete; check mirrors and look for approaching vehicles first.
- Call Mercedes-Benz customer service at 1-800-367-6372 with questions about the recall or dealer scheduling.
What happens at the repair
At the dealer, a Mercedes-Benz technician updates the exit warning system software so the audio and visual alerts can warn occupants about approaching vehicles. The software update and related 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.
