You might call a shop who does fab work for your local utilities. People who fab up traffic rated plates & drainage grates. They could quote you on & give you advise for a solution to your problem.

Always tough to tell from photos but it looks sloped to keep water away from your garage. Maybe if you call a concrete contractor the could give you a quote to fix your issue & still allow for proper slope to keep the water headed in the right direction.

Unfortunately you have a curve there. That will likely make fab expensive. Asphalt patch usually is a temp fix. as you see, most pothole fixes don't last. If you have some hot asphalt put in properly, it might go a long way to a lasting solution. As mentioned before, drainage is important to keep in mind. you want any rain water to flow away from the house.

I used to do a lot of work with Grating Pacific. They have locations in Tracy & Madera. They might quote a ramp system for you. Maybe something aluminum? that you can store in the garage? Who knows. But, worth giving them a call & with some photos to see if they have any suggestions.
