Confusion broke out on the formation lap at Sepang when multiple Formula 1 drivers suddenly lost power. Reports identified Max Verstappen, Lewis Hamilton, Charles Leclerc and Lando Norris among those affected, with cars slowed dramatically during the pre-start lap.
Coverage of the incident said a software bug triggered the problem. The episode led to questions over whether affected cars should have been penalised and prompted criticism from drivers and commentators about how Formula 1 handled the situation.
