Well, Islam has not a church to begin with, so that a Reformation analog is simply impossible.
However, there was a broad-based array of regional, very loosely coordinated reform movements that called for something on lines like: "back to the sources, let's stop entrenched mundane practices, cult of saints is idolatry, down with all this corruption among usual religious elites". Wahhabism is just one of the most successful results of this renovation/restoration discourse, but by no means the only one. And it is arguably pretty successful, at least since oil has been found in Saudi Arabia.
The movement as a whole was nowhere near as cohesive, structured and connected as the Christian Reformation was, though the pilgrimage gave some sort of a common focus beyond regional matters. And it was peripheral, in the sense that the Ottoman Empire was maybe affected less by it (the same could be said to be true for European Reformation as well: with the exceptions of England and partly the Low Countries, none of the more central cores of Western European civilization went massively Protestant). And it was quite spread through time, with first instances in early sixteenth century, but the whole movement really taking off a couple of centuries later.
