With so few units, it seem likely to me that you could bypass the committee. If you have enough other owners who are annoyed by the parking matter, you could between you require the committee to call a general meeting in order to put a motion directing the committee to issue a notice to comply.
Since it would be clear that such a resolution would pass since you have the numbers and the resolution would compel the committee to act, it should be easy to make it clear to the wavering members that it would be easier to just support a resolution by the committee to issue a notice to comply without all the rest of the bother.
On the other hand, if it become clear that few if any of the other owners are actually all that bothered, perhaps it is not worth a fight.
