According to Sepang CEO Datuk Ahmad Razlan Ahmad Razali, sales for the grand prix reached only 60 percent recently, in contrast to the MotoGP event, which is expecting a sell-out for this weekend's round of the championship.
Local media reported Razlan as saying the TV viewership for this year's Malaysian Grand Prix was the "lowest in history".
The circuit has a contract to host the grand prix until 2018, but a meeting between Sepang's shareholders and the ministry of finance will be held this week to decide the event's future.
Razlan said Formula 1 was no longer an exciting sport and that the country should re-consider the future of the grand prix.
