Check engine light - P0171

So I have had the car for about 2 months and the check engine light came on last night after some hard acceleration. Went to Autozone and got them to check the code - it is a P0171 - Fuel trim bank one - said "Too Lean".

The car is an 07 V and everything else seems to be running fine. I am not positive about this but I think the warranty would have just ran out?? Anyone have any ideas or seen this before?

Thanks in advance!
