Overview

2021 Mercedes-Benz AMG GT

The 2021 Mercedes-Benz AMG GT is a high-performance coupe that delivers exhilarating driving dynamics. However, as a used purchase, its appeal is tempered by an average reliability assessment. A notable concern is the high volume of recalls, particularly those affecting the eCall system and Electronic Stability Control (ESC)/Traction Control System (TCS). While the manufacturer has issued remedies, buyers must confirm these are completed. The car's powerful 4.0-liter V8 engine and rear-wheel-drive setup provide thrilling acceleration, but fuel economy is modest, leading to potentially high fuel costs.

Critical Failure Risk

Recalls indicate a persistent issue with the eCall system's SIM card software, potentially preventing automatic crash notification. This is primarily a software-related problem requiring manufacturer updates.

Early detection can help you avoid a $300-$700 repair.
