P0460 Fuel Level Sensor Circuit Malfunction
I'm kind of fuzzy on technical aspects of this, but it sounds like the fuel sensor may be dirty and it's giving off the code. Maybe it just needs a new fuel filter? I feel dumb when it comes to this stuff. Either way, you'll have to take it in under warranty, or wait until that tank of gas runs out and try gas from somewhere else...
