Nintendo Switch Joycons with malfunction?

I have the following problem with the Joycons of my Nintendo Switch:

My two Joycons (more of the left) are not calibrated properly (I run forward in many games by myself). Even after multiple calibration and reset to factory defaults, this does not improve. What should I do now (is there a trick?)

Apparently your Joycons are broken. Send it to the Nintendo repair service. This is in most cases even free
