Not quite as bad, but when I tried out a car in 2008 with Ford/Microsoft's SYNC system (voice interface), there were cases where pressing an unconfigured button would disable the sound system until you restarted the engine. See number 8:

Also, whenever the power goes out, I always express thanks that the toilets still work, and they didn't introduce some npm-style pointless dependency.
