When do coil packs fail?
Okay, I'm about to go into the dealer for my third coil pack failure (most likely the cause). My first coil failed about 97K, seconds around 115K, now at 123K another. I'm assuming it will be a different coil pack that the two replaced already.
Anyway, when do these things typically fail at? Am I just having some bad luck, or they fail around early 100K? I'm asking because I'm considering replacing the four at this time, than to wait for next to fail.
I've been lucky that the ones that have failed happened to fail while I was close to home, or at work. But what if it's 1/2 way through a vacation?

I've only had one fail (right around 100K by my memory), and that's pretty much because I botched a job on cleaning the intake manifold with a bit too much cleaner. Other than that they've run fine. I'd check the gap on the spark plug under the coil in question, but also see how clean the plug is.

Can I say that for whatever reason, the coil packs then are prematurely failing on my RX?
I guess I should proactively replace them then...

Plugs are one thing I don't care to tackle myself, so if nothing else, I've been too quick to replace them. I had my first set replaced at 58K, then again at 115K when my 2nd pack failed.

Whenever I did plugs with my uncle and cousins using single prong plugs (like most plugs), I'd always check the gap on them, because even though they are new, sometimes they aren't gapped properly.

My view about things that are manufactured together have close to the same life. So if one coil-pack goes bad, it is very likely the others will go. So if one fails it can be an anomaly but if more than one fails the chances are the lot will have similar life.
Incidentally, one of my coil-pack failed immediately after I installed new plugs [140k miles]. Since I have longer arms, for me replacing plugs gets 2/10 in difficulty. [changing oil filter is 3/10].

I plan to replace the back one that is hardest to reach with a new coil pack when I do the spark plugs in the next week or two. Use the old but still working one as a spare, keep it with couple of hand tools in the car.

I'm taking the opinions here to be that I should check the gap first (dealer will do that), but that I should probably replace the remaining four.
My whole deal is, the three failed when I was close to home. I don't want one failing when I'm like 200 miles from home and I have to scramble looking for a shop/dealership to fix and lose one day hanging around (even with loaner).
Thanks guys/gals (if there are any).
