Agree with above, coils have the same amount of use, now, you didn’t tell us how many miles are on your Corolla?? 80K or 300K miles?? Is your spark plug tube seals leaking oil, that can cause the COP (coil on plug) boots to swell and the COP start arcing…
If the spark plugs have been replaced, were they replaced with the correct OEM spark plugs, and not the will fit spark plugs?? Almost always recommend installing the same plug that came out, matter a fact, I jut about refuse to install a non OEM spark plug, seen to many issues over 30+ years…
I’m a replace one coil at a time guy if they are easy to get to, but if they are hard to get to then I replace them all, I always give the customer the option for one or all… But if a 2nd one goes out fairly quick, then I just replace all the rest… And I almost always replace all the spark plugs when the 1st coil goes out…
