Wheel bust after 10 months, is this normal / usually covered by warranty? Not sure if this is the right place to ask...

I bought new bike about 10 months ago. The past few weeks I've had no end of trouble with the rear wheel (Mavic Aksium) in regards to spokes.

About 4-5 spokes on the non-drive side consistently come loose. I tighten them, then after riding for about 15 meters I hear the "twang" as they work themselves loose. One of them snapped right off at the nipple, looks a bit brittle where the break was.

Questions:


Is this normal for a wheel to wear out so fast? I've done about
2500km on it.
I'm missing 1 spoke, and loose on about 4 now. Is the wheel ready for the bin, or is it worth fixing? 
Is this something that is normally covered in bike manufacturer
warranties, or is it a case of "sorry mate, its just general wear"
1) It's hard to say what's normal - what sort of riding have you been doing on it, as in, have you been going over a lot of curbs and potholes? The more you bounce on it, the more strain it'll have.  Have you hit one particular pothole hard recently?  How heavy are you? The heavier you are, the more likely you are to damage the wheel.

2) You should take it to your LBS, they'll be able to tell you the answer to this, but most likely they'll be able to repair it and re-true the wheel.

3) Depends on who you got it from.. and what warrantee you have I guess.  Probably going to be a general wear though I'd suspect.
