To be honest I've had very few problems with electronics failing, per se, on my 100+ electrics, LPs and diesels. My biggest problems come in with intermittent system glitches in the software especially on my Clarks and now my newest 2 Toyotas. Did you know on the newest line of Toyotas you can no longer jumper pins 1 and 4 to read the codes? You only get a heart beat. I had to have a tech come out with a lap top...he ended up updating the software! The truck was only a month old!
