Over the first two years of his career in Formula One, Di Resta had only four failures to finish against his name. The Scot, however, already has four this season, and more alarmingly three of those have been in the last three races.
In Hungary, Di Resta's Force India suffered a hydraulics failure four laps from home; in Belgium, the 26-year-old was broadsided by Williams' Pastor Maldonado, while in Italy his race lasted a matter of seconds after another collision for which he was to blame.
Overall, after starting the season by scoring points in seven of the first eight races, Di Resta has drawn a blank in the last four.
From potentially being in the shop window, Di Resta appreciates even his own team may be looking elsewhere, despite the fact there is an option on his contract for 2014.
"This is the crucial time for people to make decisions and for me to secure my future, wherever that may be, here or elsewhere," said Di Resta, speaking to Press Association Sport.
"With regard to Force India, it's about understanding the tools you have and doing what you can with them.
"I would certainly like to think I've enough of a reputation and I've shown the team that when the tools are delivered, and when we've a working package, we are strong together.
"I have the utmost respect for the team and what they've given me, and I'd like to think it's the same for them, that we're a family working together."
Di Resta's situation has not been helped by Pirelli's change of tyres in the wake of the failures during the British Grand Prix at the end of June.
Force India were one of the few teams to fully understand the rubber prior to that race, and the results underlined that fact.
But since alterations were made to the tyres the best result the team has achieved came with Adrian Sutil's ninth place in Spa.
It means any chance of a repeat of last season's career-high fourth-place finish in Singapore going into this Sunday's race at the Marina Bay Street Circuit is remote.
"It's looking tough at the moment, but I'm not going to rule it out," said Di Resta.
"As things turned around quite quickly on us, so things can easily turn around the other way.
"We'll work away. As long as we give 100 per cent, what can you say. That's all you can ask for.
"Unfortunately, we've just not got the speed at the moment. We need to get performance back before we are going to start scoring points.
"The tyre change has definitely hurt us more than any other team, and other teams have caught up massively and overtaken us, even the likes of Williams and Sauber.
"Maybe there have been other things, but there has been one dramatic change on the car and as a result we've lost our strength.
"All I can say is, we're fighting hard."
