Since the car is under warranty, I'd just make an appointment and bring the car in. Thats why you paid the premium, to harass the stealership when stuff goes wrong.

P0229 = throttle position sensor switch C/accelerator pedal position ( APP ) switch C - circuit intermittent, check wiring, poor connection, let the warranty fix it
