1DX bad curcuit board!
Ha, the only thing redundant about my airplane is two sets of plugs per cylinder! The 1DX is a stunning camera but it did seem a bit odd that the board went bad so quickly.
No it isn't. How electronics work, if they are going to fail they will generally fail within the first few months of usage. If they last the first few months or first year they will generally last a long time. This is why most electronics have a 1 year warranty: if it works fine for the first year it'll keep on working...
