I was going to schedule an appointment for the 2 recalls (airbag and fuel pump) along with oil service. They also said service recommendation for mine is to change spark plugs (mine is an '08 with 85K miles). Of course I won't do that at the dealer but is it really necessary or just preventative maintenance?
