The 2017 Mercedes-AMG G65 is a very powerful and fast SUV; and it’s not cheap at all (started from $220,000). Packing a hulking twin-turbocharged 6.5-liter V12 engine, the beast is capable of producing 621 HP and 1000 Nm of torque. The heavy SUV can accelerate from 0 to 60 mph in 5.3 seconds. It’s so wild that it requires a speed limiter when it goes backwards, or else it will endanger the driver and anyone who may be around the car.
That is the reason Mercedes-Benz issued a recall for 20 units of the 2017 Mercedes-AMG G65 in the US. This recall affects the models built between September 6, 2016 and October 10, 2016. It was reported that the reverse-speed-limiting software on the affected vehicles isn’t properly calibrated, so it would let the vehicle continue to accelerate backwards even after it reaches 16 mph, which is the very speed limit for a safe turn over. A sudden steering input when speed rises above that limit could make the vehicle unstable. And given the boxy shape and the agility of the Mercedes-AMG G65, seeing the possibility of it rolling over after making a quick backward turn is not so difficult.
According to Mercedes, incorrect ECU software is the culprit behind this defect, therefore the company has issued a fix to tame the affected G65s. Owners only need to bring the SUV to the dealership and it will be given a free software update to stem reverse speed with the proper limit. The recall notifications have been sent to owners since a few days ago through first-class mail.
