Sergio Pérez's Monaco Grand Prix was marred by controversy as the driver of the No. 11 car was penalized for a false start, stripping Cadillac of their first points in the inaugural season. The penalty report stated that Pérez started from position 16 instead of 18, which is a significant advantage at Monaco. This mistake led to a pass-through penalty, which ultimately affected his chances of scoring points.
Pérez's teammate Valtteri Bottas also suffered a DNF, while Max Verstappen retired on the opening lap.
