Vibration noise in the emergency brake handle

When it is serviced at your Hyundai Dealership, mention the noise and as it is under warranty, they will sort it out for you.

What kind of clicking noise do you expect to hear? Applying the main brakes is usually a silent activity.
If you are referring to the emergency brake, it is the clicking of the ratchet when applying the emergency brake. The clicking is the sound of spring loaded metal teeth bouncing along a cog wheel. The action is similar to the teeth on a hand winch that does not allow backward turning. If when applying the emergency brake the sound is not heard then the spring may be broken or dislodged.
Does the brake engage? Does the handle stay pulled until the brake is released? If not then the locking of the brake is not happening.

It depends on what your point of reference is. Is the car vibrating when you brake? Or Do you feel it drifting while you drive? Does it feel loose or hear noises coming from the front end? Bottom line is it will depend on the symptom of your vehicle as it relates to the problem. Does your 2003 Maxima need an alignment or will it ever?? Probably so!

probably a bad wheel bearing

The first thing I would check is for a bad wheel bearing. If the noise lessens when turning left than I would look at the left front first. Chalk the rear wheels or set the emergency brake. Put the transmission in neutral. Jack up the left side of the car. Grab the coil spring and rotate the tire by hand. If you can feel/hear the noise than your on the right track with the bad wheel bearing. I can give you instructions on how to replace if you need them.
