Respuesta :
The fee is called an "excess mileage fee" she she has driven more miles than she was allowed in her lease agreement.
I believe the answer is: Lease penalty
Lease penalty refers to a financial punishment that is given to the lease if a clause within the lease contract is being breached/violated. Examples of events that can cause lease penalty could include things such as not paying monthly fees, surpassing miles allowance, unsafe usage of the property, etc.
