Ferrari are going through some tough times recently.
After Singapore, where both their drivers failed to finish, came Malaysia with Vettel's heroic race leading only to a fourth place.
The engine trouble experienced at the Malaysian Grand Prix caused company president Sergio Marchionne to make changes in the "quality department" of the Ferrari team.
Sebastian Vettel's championship ambitions look in thread now, as Lewis Hamilton is 34 points ahead of the German.
In Singapore, Vettel caused a clash with Max Verstappen and teammate Kimi Raikkonen. Two weeks later in Sepang, he suffered an engine issue during qualifiers and had to start from the back of the grid and was only able to claim 4th spot.
Raikkonen, on the other hand, qualified second and was looking for a battle with Lewis Hamilton for the win, but faced similar issues in the build-up to the race. They stopped him from starting in the race and even though Hamilton lost the race to Verstappen, he managed to extend his lead in the championship with just five races remaining.
Fans are left wondering what would have happened if Ferrari drivers were not affected by the engine issues, and president Marchionne has his explanation for the accidents.
"On Sunday, both Ferraris could have won the race," Marchionne claimed a day after the Malaysia Grand Prix.
"That's a fact. It could have also been the same at Singapore, that's another fact.
"It's also a fact that we've got some issues with our power units because we have a young team, but also because the quality of the components is not at the right level for a race car. We are intervening and we are working on it.
"It's almost fortunate we haven't had that problem until the Malaysian GP. Now we're working on the quality department and making some organisational changes.
"Having this kind of problem during the race make us angry. That's not a big problem if this kind of issue appears in our factory, but it's really ugly when you're in second place on the grid and you can't start the race."
Recent results saw Mercedes extending their lead over Ferrari in the Constructors' Championship to 118 points, which was only 44 before September.
