Strong braking/full braking at 60 km/h without apparent reason

Moin, my wife drives on a straight country road without obstacles in super weather and at once the EQE puts a full brake at approx. 60 km/h without any obvious reason. Since we could not find animal hair or eagle feathers on the cooler afterwards, I left this at first. Now I drive the children to school last week and on a well-dripped road the car brakes down again really strongly. This time not to a standstill, but already so strong that I worry about h Luckily that didn’t happen. The boys in the workshop have never heard of it – as always – and can’t do anything at all on the car, because it has to be due to the electronics/maybe/could/who knows. Achso –> The driving mode at the first braking was Comfort with standard recuperation. In my braking was the setting on ECO + D car. In “D Auto” it is annoying indeed that the car is just in the car. It also happens that if the front man bends, the car slows down too much in my opinion and interrupts the flow of traffic unbelievably. However, with the brakes described above, there were no obstacles in front of the car. Maybe it is enough if a bird or a thick bumblebee flies along in front of the sensor. However, this would be a real problem on high-speed roads. m. My question to you: did someone have such an experience here? Greetings!
