The C190/R190 two-door AMG GT does not use a torque-converter automatic. It uses a rear-mounted Getrag/Magna 7DCL750 seven-speed dual-clutch transaxle — the same family as the Ford GT unit — and it is the single most expensive failure point on the car. Owner and specialist report… Repairs typically run $5,000-$15,000. Severity: high.
The GT 43 and GT 53 use the M256 inline-six with a 48-volt EQ Boost integrated starter-generator that replaces the conventional starter and alternator. Two distinct failures cluster here. First, a safety defect: NHTSA campaign 24V100000 covers 2021-2023 GT 43 and GT 53 whose 48-v… Repairs typically run $900-$3,500. Severity: high.
On the X290 four-door AMG GT (GT 43 / GT 53), the transmission wiring harness can be routed incorrectly so that the electrical connector sits where it is exposed to water and road spray. The connector corrodes, and the corroded contacts can short-circuit — which Mercedes-Benz its… Severity: high.
NHTSA campaign 21V961000 covers 2019 AMG GT 53 and AMG GT 63 four-door models and calls for replacement of the fuel rail together with the fuel injectors. A defective high-pressure rail or injector interface on a direct-injection engine leaks fuel into the engine bay under pressu… Severity: high.
On 2019-2021 AMG GT 63 and GT 63 S four-door models (sharing the recall with the 2018-2021 E63 S), the starter motor positive cable was not installed correctly at the factory. The misposition lets the power-supply harness wires chafe against adjacent structure. Once the insulatio… Severity: high.
The C190 AMG GT mounts its rear transaxle on three ACTIVE (electronically controlled) mounts that stiffen under hard cornering and soften at idle. The most common reported failure isn't rubber breakdown — it's wiring harness or connector corrosion at the mount sensors, which trip… Repairs typically run $400-$2,800. Severity: medium.
The AMG GT has been recalled repeatedly across its entire production run for defects in the telematics communication module that carries the emergency call function, and the campaigns stack across different root causes rather than repeating one. NHTSA 21V058000 covers 2016-2021 A… Severity: medium.
The wheel-hub center caps on 2019-2020 AMG GT 53 4MATIC+ and AMG GT 63 4MATIC+ four-door coupes were not manufactured to specification. The fastening clip mechanism cannot withstand the stresses induced in normal driving, and the cap detaches from the wheel hub while the vehicle… Severity: medium.
NHTSA campaign 20V395000 covers 2019-2020 AMG GT vehicles that left the factory with an incorrect Electronic Stability Program software version installed. With the wrong calibration, the ESP system can react inaccurately — intervening when it should not, or failing to intervene c… Severity: medium.
