The 2017 Mercedes-Benz AMG GT has 6 recalls, the most serious being a carbon-fiber driveshaft that can separate from the vehicle while driving, causing a sudden loss of power and raising the risk of a crash.
On the occupant safety side, vehicles equipped with AMG Performance Seats have a passenger seat occupant classification system that may misread who is sitting in the front passenger seat. If the system classifies the occupant incorrectly, the passenger frontal airbag can either fire when it should not or stay inactive when it should deploy in a crash, either outcome raising the risk of injury to that passenger.
There are also two related recalls covering the emergency call system, which automatically contacts emergency services after a crash. A software fault can cause the system to report an incorrect date, time, and vehicle location, meaning first responders may be sent to the wrong place after a collision. Prior repair attempts did not fully resolve the issue, and a broader filing later extended the scope of the fix across a wider range of model years and classes. The practical concern is the same in both cases: a delay in emergency response following a crash.
