Last weekend's Red Bull Ring event descended into near farce as race control could not keep up with the more than 1200 track limit offences that were alleged to have taken place.
Delays in going through them eventually meant the final result was not sorted until many hours after the race.
As part of that late investigation, several drivers, including Sainz and Lewis Hamilton, got penalties that shuffled them down the order.
Sainz found out that he had dropped from fourth to sixth just as he took off from Austria to head home, and was far from happy about things.
But he believes what is important now is F1 and the FIA take firm action to prevent repeat trouble.
The FIA had already suggested that the Red Bull Ring should build new gravel traps to improve matters at its venue, but more action is needed according to Sainz.
"There has been so many solutions [offered] and, for some reason, we keep postponing," he said when asked by Autosport about what the solution was to the track limits problem.
"It's like an alarm: postpone, postpone, instead of acting on finding solutions for these kinds of circuits.
"For me, it is time to act, whatever they want to do. I would be even happy if you leave the rule the same and you put a [detection] loop, because at least the loop is telling me immediately if I've done a track limit and I know I can correct it."
