Yes, golf drivers will eventually lose their pop. It's hard to put an exact time frame on this. Golf drivers tend to lose their pop after a certain number of hits. If you play twice a year, chances are your golf driver still has plenty of life left to it.
For golfers that play a few times a week, your driver will likely start to lose its pop after about six or seven years. You won't see truly terrible shots or a loss in thirty yards; it's usually just a difference of ten to fifteen yards. When you put a new club in your hand, you would notice the difference immediately. If you feel as though your driver has lost its pop and it is only two or three years old, you may want to have the manufacturer take a look as there could be a defect.
