My leased vehicle is supposed to have 2 years of free oil changes and my 2 years isnt up until November 2016. So I made an appointment and had my husband bring it in today and they tell him our oil changes arent free anymore. That it was 2 years or 24,000 miles... Well we knew nothing about that otherwise we would have been prepared to pay & I wouldnt have made an appt with them! What a waste of our time, gas, and day! Like they couldnt have just told us that last time we were in a few months ago... Thanks for nothing Rosner Chevy! You wont be getting out service AGAIN!
