You need to check your by-laws, to see which by-laws (if any) this behavior is breaching. Some buildings have by-laws that restrict how the parking lots are used (ie, just to park a vehicle). In some buildings the parking lots are owners property, in others, they are common property, and commonly, if common property there may be an exclusive use by-law registered that has a result that the common property parking bay becomes the owner’s property. It’s complicated.
The Owners Corporation has more say in how the area is used, if it is common property. But what can be done will depend on the actual wording of a by-law. (You can also consider getting a new by-law adopted to regulate the activity – see a strata lawyer about this, if you are interested, and not adverse to spending money on that.)
The best approach is to make a noise complaint. An owner cannot damage the amenity of other owners to enjoy their property (I’m paraphrasing), so just like someone smoking with the smoke penetrating your Unit, or playing loud music to upset your amenity, you would have a reasonable chance to get an order to prevent this. But you need evidence on the harm being done to you, not just a complaint. Maybe talk with a strata lawyer?
