Driver Lewis Hamilton was leading the last race in Abu Dhabi and looked set to claim the chequered flag, before he lost power in his car and was forced to retire.
Reliability has been an issue for both Hamilton and team-mate Jenson Button throughout the 2012 campaign but Neale believes the issues can be resolved before the next race in Austin, Texas this weekend.
He told the official Formula One website: "The failure we had in Abu Dhabi was very painful.
"Having said that, we've just done 1,500 trouble-free kilometres with the same car at the Young Driver test last week.
"So yes, we are very mindful of the Constructors' Championship, but we are still taking performance upgrades to this Grand Prix. We are not taking an overtly cautious approach, but we are going to be very diligent."
