mysterious car issue

I just had my engineer tell me something along the lines of „we have an issue, we are looking into it“ without any second radio call on confirmation what the issue is

I just started noticing that no matter what engine mode I was in my straight line speed was massively down all of a sudden - like max. 310khp

I asked for vehicle condition but engineer said all is fine

got handed down from p8 to p13 in 2 laps

I feel like the AI has a massive ERS and straight line speed advantage anyways but this just basically ended the race for me

anyone else encounter this? is this meant as a technical failure/issue? if so, why was the engineer acting like all was fine
