What's wrong?
The front acceleration sensor on the 2021-2022 Mercedes-Benz Gle 350 and Gle 450 helps the restraint system decide how the front air bags deploy in a crash. Its wiring harness is the bundle of wires that carries the sensor signal to the air bag control system. That signal has to arrive cleanly and on time for the front air bags to work as designed.
On these vehicles, the harness for the acceleration sensor was routed incorrectly during production. With the wiring in the wrong path, the sensor signal can be affected, which can keep the front air bags from deploying properly. Mercedes-Benz found the issue after a crash test showed a deployment pattern that did not match the design specifications.
There is no warning sign before failure. The driver would not receive a warning message or light because the problem is in how the harness is routed, not in a part that alerts before it fails.
Who's affected?

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific SUV.
What's the safety risk?
If the affected air bag wiring harness is routed incorrectly, the air bag does not deploy properly in a crash, which increases injury risk. There is no warning sign before failure. Schedule the dealer inspection and harness rerouting soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2021-2022 Mercedes-Benz Gle 350 or Gle 450 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free front-acceleration-sensor wiring-harness inspection and rerouting so the front air bags can deploy properly.
- Bring the recall notice if Mercedes-Benz mailed one, and reference recall number 24V724 when you call.
- Call Mercedes-Benz customer service at 1-800-367-6372 if the dealer cannot confirm repair timing.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front acceleration sensor wiring harness and reroutes it if the harness was installed incorrectly. The inspection, routing work, 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 under warranty and were not previously subject to this condition. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
