Maybe? When it's level it drains pretty well as the driveway slopes gently to the right side (north) of the garage (the lot is east-west, garage faces west) so as long as it's level it works out pretty well. When the landscapers came in to fix it the first time they added a second drain to the right of the garage as well which helped (but only when the driveway is level).
If it keeps settling adding a small trench at the foot of the garage to the drain would probably be the solution.
Here's a video of the water flowing towards the garage:
