Failure rates for HPC loaders?

Hello, am also from the Stuttgart area and still waiting for my I4. Before delivery I look back and forth into the ENBW app like the hpc load on my regular routes looks and was actually good things – are the failure rates really so high? The app sometimes shows β€žin maintenance, is that really much more? In the city center the occupancy in the last months on the AC columns felt strongly increased – almost always hybrid, partly for days the same Pappenheimer (or Mo-fr, returning every day. Really terrifying!
