If all the lights are coming on like they should when you first start the car, but do not go out after starting, it's likely going to be the ignition switch not returning all the way from the start position to the run position. This isn't very common and should be verified before anything is replaced. I don't see how any one sensor could cause all those lights as the dealership states. I recommend having a qualified independent technician, like one from YourMechanic, come out to you and diagnose your electrical problem.
