I've had it happen to mine, a Day One controller, 10 days before it was a year old. I rang Microsoft who replaced it but with a standard one and gave me £10 as they had no Day One editions left.
Just to add mine just happened out the blue and would light up as if it was connected but wouldn't do anything even if i connected via USB.
