We might never know for sure, but chances that 4 different new parts fail on Mercedes are extremely slim.
With new technology coming every day - mechanics have hard time to educate themselves how to deal with it and it is pretty common that they have no idea how to troubleshoot newer cars.
Read old topics in W163 and W210 sections.
In first years of digital cars - mechanics often replace one $2000 computer, than other $3000 computer - only to find later that it was $140 sensor that malfunctioned.
Than you read that dealer filled gasoline into diesel car.
So your saga is not that new to the brand in America.
