That should still be under original warranty that I believe is 36 months 50K miles on the powertrain. That may be out if the original owner did not perform regular maintenance according to their requirements. As stated earlier the lemon law is for one owner, and is applicable when the vehicle has been in to a dealer for repair for the same problem at least three times. Keep leaning on them as being a nice guy will get you nowhere. By the way are you a repeat customer to the lot that you purchased it from?
