Heikki Kovalainen believes the penalty he received from the stewards after the Australian Grand Prix was a "bit harsh".
The Finn was handed a five-place grid penalty for the Malaysian GP after stewards found him guilty of passing other cars before the first Safety Car line.
Kovalainen passed two cars as he made his way to the pits while the Safety Car was out on Sunday and he was slapped with a post-race penalty.
The Caterham driver accepted the punishment, but nevertheless feels it was "harsh".
"Tough day today, never mind one of those races that happen sometimes, bit harsh penalty from stewards for the next race but that's life too!" he wrote on Twitter.
Kovalainen was forced to retire 20 laps from the end with a suspension problem, but he is confident the team will iron out the issues before next weekend's Malaysian GP.
"I felt the car starting to pull left under braking so we brought the car in to take a look and it seems like a front left suspension problem was causing the handling imbalance I'd felt for a few laps before we had to retire," he said.
"I'm sure we can fix both problems for next week and we have shown today what a step forward we've taken, so it's not bad news, it's just one of those days."
