Mercedes opened investigations in February 2018 based on testing of an AMG GT which showed the ESP system might not have been adapted for the different brake types of the vehicles.
The automaker discovered the failure mode system for a failure of the brake negative pressure supply might not have been implemented into the software.
Mercedes fixed the problem in production, but in July 2019 the supplier contacted the automaker about a test where the ESP system failed to perform properly.
Mercedes-Benz says it found a "yaw rate sensor drift" which caused malfunctions of the electronic stability program system.
The driver won't have advance warning if the problem occurs.
More than 5,000 vehicles are recalled in the U.S. and 415 are recalled in Canada.
The Mercedes ESP recall is expected to begin August 28, 2020, when dealers will update the ESP software.
