Jules Bianchi of Marussia and Caterham's Charles Pic face 10-place grid penalties at next weekend's Japanese Grand Prix after being reprimanded following Sunday's race in Korea.
The French duo automatically get the grid penalty for accruing three reprimands this season.
Also reprimanded by stewards after an incident-packed race at Yeongam were Pic's team-mate Giedo van der Garde and Bianchi's stablemate Max Chilton.
Bianchi and Pic received their reprimands for failing to respond to yellow flags, whilst van der Garde and Chilton were punished for lapping too quickly during the safety-car period.
Stewards opted to take no further action against McLaren's Sergio Perez and Force India's Adrian Sutil, who were also the subject of post-race investigations.
