Somehow my wife's 2016 GT CX-5 with 5500 miles on it got a big chunk taken out of the sidewall. It's deep enough I can see the belt a little. Any chance that would be covered by warranty? Can that be patched?
agree with Yrwei,
it's cheap enough now to get a new one and with only 5500 miles on the the other three, I don't think there will be a major tread depth difference
I wouldn't take a chance on patching up a sidewall, too dangerous and why risk a blowout on the highway, just get a new one.

Good catch!If "somehow" hit something hard enough to take off a chunk of sidewall rubber then you may need to get a realignment. Ed
Don't think Mazda dealer would handle the warranty on OE tires. They'll direct you to contact the tire manufacture if you have defect on OE tires and you'll find separate tire warranty pamphlet in your owner's manual booklet.
In OP's case there's no warranty and the tire is not patchable. Your only choice is to buy another matching Toyo A23 tire with similar tread depth and do it ASAP. The good news is this OE Toyo A23 tire is not expensive like it used to be, the price has dropped from $269.31 to $145.42 each from Tire Rack!
Tire warranty is provided by the tire manufacturer, not Mazda. Most Mazda dealerships can warranty a tire that originally came on a new Mazda, if the tire failed due to a tire manufacturer defect. Road hazard incidents are not covered on tires that came with a vehicle when new.
Also, the tire can't be repaired, will need to be replaced.
