What's wrong?
The front air bag wiring harness in the 2020 Mercedes-Benz Gls 580 and Gls 450 carries electrical signals between the crash sensor and the air bag system. In a crash, that signal helps the vehicle decide when and how the front air bag deploys. The harness has to sit in the correct path so the sensor signal reaches the system as designed.
In the recalled SUVs, the harness for a front airbag sensor was positioned incorrectly during development and production. That routing problem can interfere with proper front air bag deployment in the specific crash condition identified by Mercedes-Benz. Vehicles outside the recall group have the harness routed to current production specifications.
There is no warning sign before failure. The driver will not receive an alert because the problem is in the harness routing, not in a wear part that gives a visible or audible symptom.

What happens at the repair
At the dealer, a Mercedes-Benz technician corrects the front air bag wiring harness routing so the harness follows the proper path and the air bag system can work as designed. Parts and labor are covered by 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 under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
