O2 Sensor - 33K miles

I've got an '04 2WD SE. Got an SES light, found out how to check codes here on the forums and got an 0057. Looks like a right bank O2 sensor heater voltage if the codes carry directly from the Infiniti page. I'm just wondering if this is something to look forward to with this truck, or if I just got the luck of the draw for one to fail early(?). I've never had to replace an oxy sensor before 100,000 on anything, so was kind of a surprise to me to have this code.

Thanks,
