Such was the extent of Verstappen's problems that the Dutchman did not set a lap time at all in FP2, hampering his preparations ahead of another crucial race in his quest for a fourth consecutive championship.
Unable to remedy the problem, Red Bull were forced into making significant changes to their star man's car ahead of FP3 and qualifying on Saturday.
F1 champ Max Verstappen facing FIA penalty
Ahead of the rest of the weekend's action, Verstappen's car has undergone an engine change, with Red Bull not willing to risk any further issues for their star.
In order to do this, the FIA has confirmed that Red Bull broke the overnight curfew, although they will not receive a punishment for this given it was the second of their two exceptions allowed for the season.
Similarly, Verstappen will receive no sort of engine penalty for the change.
Whilst drivers changing their power unit or parts of it are often subject to a grid drop of some sort, in this instance, Verstappen will not receive a punishment due to the fact he has changed back to an old engine that was already in his pool, rather than introducing any new parts.
However, things are not all rosy. During FP3, Sky Sports commentator David Croft suggested that Red Bull were now very tight on engine parts for the remainder of the season, and suggested that Verstappen could still take fresh engine parts pushing him above his permitted amount for the season, and therefore a penalty.
If Red Bull were forced into this change, it would be preferable to do so at the Brazilian Grand Prix, rather than the final few races in Las Vegas, Qatar and Abu Dhabi were overtaking is harder.
