I had to replace one a couple years ago, so i was curious as to how many people had the same experience.

It actually caused smoke to get into the interior. Ruined an oxygen sensor and catalytic converter.

Its never been an issue for me, I still have a slight misfire from time to time, but given that I have no idea which cylinder/cylinders its coming from, I dont want to start replacing coils at random, even if I do have an extra one laying around.

funny....i thought this was going to be a bigger problem than it turns out to be.

at the time, i thought....guaranteed recall

lucky thing is that the catalytic converter was covered under the emissions warranty.

Never had to do ignition coil, but... The whole ignition was our problem and car would stall while driving. Had to put in a whole new ignition !!! Cost big bucks too.
