Sebastian Vettel has admitted his 2014 troubles are far from over.
The world champion said that even if his run of poor reliability ends soon, Renault's early-season crisis will come home to roost later in 2014.
That is because of the tighter-than-ever longlife engine rules, where drivers may only use five individual V6 engines, turbos, electric motors, batteries and control units in a single season without penalty.
The German and his Red Bull will begin tumbling down the grid once that allocation is exhausted.
Based on his list of component changes so far, Vettel told Germany's Auto Motor und Sport: "It is easy to calculate that I will not have enough" for the entire 19-race calendar.
