2013 malibu code P228D
 

Fuel pressure selenoid bank one control performance out of range . Wife had a reduced engine performance message but no driveability issues. I drove the car on 2 occasions later and had a check engine light code but no other issues. Onstar advisor gave the code to me and said it said to service at your leisure . With 41,200 miles am i gonna have to cover this repair ? and if so how much do you think it will run ?
