As long as the issue wasn’t caused by misuse or a road hazard, there’s some good news:
Alignment is covered under Toyota’s warranty for one year or 12,000 miles, whichever comes first. Wheel balancing is covered for this same period as well, so as long as you don’t have more than 12,000 miles on your Corolla and get it in the shop before it’s over a year old, you should still be covered. Hope this helps!
