What's wrong?
The airbag control unit is the computer that reads crash sensors and decides how the frontal airbags deploy. In a low speed crash, the passenger frontal airbag is designed to use only the first stage, which gives the needed restraint force for that impact level.
On affected 2018 Mercedes-Benz AMG GT and AMG GT C Cabrio vehicles, the control unit has software that does not match the Roadster airbag setup. The software can command both stages of the frontal airbags instead of the intended first stage. That means the airbag deployment force is higher than designed for that kind of crash.
There is no warning sign before failure. The driver will not see a light, message, sound, or change in how the vehicle drives before the airbag control software makes the wrong deployment decision in a crash.
Who's affected?
Both AMG GT variants appear under the same two component categories: air bag system and electrical system software.
| 2018 Mercedes-Benz AMG GT | air bag system |
|---|---|
| 2018 Mercedes-Benz AMG GT | electrical system software |
| 2018 Mercedes-Benz AMG GT C | air bag system |
| 2018 Mercedes-Benz AMG GT C | electrical system software |
| Units affected | 2 |
| Field incidents | NHTSA has logged no field incidents to date. |
A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific car is included.
What's the safety risk?
If the air bags do not deploy as intended, occupants face a higher risk of injury. There is no warning sign before failure, so the VIN check and dealer repair matter even if the vehicle feels normal. Schedule the software update soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2018 Mercedes-Benz AMG GT or AMG GT C is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free air bag control unit software update, which fixes the low-speed crash deployment issue.
- Bring the recall notice if you have it, and reference recall number 18V724 and Mercedes-Benz recall 2018100008 when you call.
- Ask Mercedes-Benz customer service at 1-800-367-6372 if you need help confirming dealer instructions.
What happens at the repair
At the dealer, a Mercedes-Benz technician updates the air bag control unit software so the frontal air bag deployment logic works as intended in a low speed crash. 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, because all involved vehicles remain under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
