Driver career mode DNF

So i decided to start a new career mode, driving as Daniel Riccardo,and in four out of the five first races (including the sprint race in China) i have had a engine failure,all in the same scenarios while i'm leading and starting my in lap ",(at Suzuka i tryed to pit earlyer and no DNF) , it might not be any real issue but i did several races driving as my self and i only had like 3 DNF in 8 races after the patch, but i set the engine failures to moderate for my next race (i'm just starting a new season since the mid race save to my own driver career mode keeps crashin when loading it) ,but if i still get a DNF in the next race (Chinese GP) with the engine failures set to moderate in the same scenario as mentioned,it might be worth looking into
