The 2020 Mercedes-Benz AMG GT has 6 recalls, all rated at the same severity level, with the most consequential being a faulty emergency call system that can fail to transmit an accurate location or connect a voice call to emergency services after a crash.
The emergency call defect traces to a missing ground wire in the communication module, which can cause the system to send rescuers to the wrong location or cut off verbal contact entirely when it matters most. Prior repair attempts did not fully resolve the issue, and the problem was addressed across multiple campaigns before a complete fix was established. On GT C and GT R trims specifically, the same missing ground wire affects the emergency call feature in the same way.
The other open issue involves the headlights, which on certain vehicles were aimed too high from the factory. Headlights pointed too far upward do not illuminate the road ahead properly and can flood the windshields of oncoming drivers with glare, reducing their ability to see and raising the risk of a head-on collision. This was also addressed across more than one filing, but the underlying problem is the same: the aim was set incorrectly before the vehicles left the factory.
