Well, at a minimum it was throwing errors and the car was making beeping sounds. That's definitely bad. Right door wouldn't close properly - might have to re-open, re-close to get it to latch. It also wouldn't open properly. First the ice-breaker would start to extend just to push it away from the frame a bit, very bad. Also, once free, it certainly wouldn't swing out by itself a meaningful amount. (What do I you call this? Auto-present? I forget) And both sides made 'weak' electrical motor sounds when you activated the opening mechanism. Something was struggling. Since the replacement they are functionally perfect, plus as soon as you activate the door from inside or outside you get a brief, crisp sound from the various servo motors involved. Much more confidence-inspiring.
