I have a 2007 Mazda 3 and my check engine light came on this week. I have 40K on the car. My dealer told me the leak detection pump needs to be replaced and will put me behind 815$.

Shouldn't this be covered under an emissions warranty? I can't believe that at 40K I would need something replaced. I also have my fuel pump go out after 22K. They replaced that under warranty.

Any help, appreciated!
