Hello,I will be glad to try and assist you with this,Welcome to Just Answer.
This can be an intermittent fault within the control unit.There is a bulletin out on tis concern that says to have the computer reprogrammed to correct this fault.A dealer will have to do this if they have not already.The charge for this is usually about an hour.
You can continue to drive the vehicle like this with no harm being done but when you get a chance I would have the computer reprogrammed to see if it corrects this failure,most likely it will.Here is the bulletin info on this concern.
