Force India driver Sergio Perez lamented a hydraulics leak which cost him a shot at making the top 10 shootout during qualifying for the Hungarian Grand Prix.
Perez was restricted to just a single run at the start of Q2 as a problem developed on his VJM07, forcing him to abandon his session.
He will start the race from 13th on the grid.
"It was a difficult session with the main issue being the hydraulic leak that affected my car in Q2," he said.
"It meant that I was only able to do one run before I had to park in the garage. Without this I think we had the potential to reach Q3, especially because we made a good step with the balance this morning.
"It’s a shame not to maximise our potential here on this track because it’s so difficult to overtake. It means we will have to try and make up the ground tomorrow with the strategy."
Team-mate Nico Hulkenberg is sure he can extend his run of finishing in the points after qualifying in ninth position.
"Considering our performance this morning in final practice, I think it’s a good effort by the whole team to make it through to Q3 this afternoon," he said.
"The wind was affecting us quite badly, but fortunately the direction changed before qualifying and that seemed to help us. Then it was just a case of keeping calm, being nice and tidy with the laps and pushing the car as much as we could. For the race I’m feeling optimistic because our long-run performance looked reasonable yesterday and I certainly feel we can be in the battle for points."
