Purchased the car and the light came on. It was serviced by adding air on the tires, so it went away for one day. I returned to the dealership and I was asked to make an appointment. After arriving at my appointment I was told it is an electrical issue and it is costly, mind you the car is no longer under the warranty in lieu it is either 4 years or 50,000 miles. Per the mechanic it will be costly.
