I don't think you can make a blanket statement like that, really. I've seen the same problem on other vehicles, too. Toyota's, Nissan's, Fords to name a few.
Quite simply, I don't think there was anything wrong with the actuator. I believe the problem is with the door latch itself, and the only way to fix it (it's cheap, really, it is) is to remove it, clean it up really well (with a spray penetrant), let it dry, lubricate well (I prefer silicone spray) and reinstall.
