brand new zuzuki aerio 2006 defected

We bought a brand new Suzuki aerio 2006 on May 20, and two weeks later oil started to leak. We took the car to the dealer ship on Dixie (were we got the car) and one of the answers was ... " every car has problems." The mechanic changed the oil for thicker one but one week later started to leak again. We asked for a new car or for our money to be returned. The dealer and also Suzuki Canada said NO. We went again to the dealer for third time when they check very well the car and said they would call us to repair the car. We being waiting for more than two weeks and nothing had happen. We had a lot of trouble with this brand new car; we wish we would never ever could buy a Suzuki car because of the terrible quality and the horrible service at the Dixie dealer ship. We don't want a repaired car, for that we could buy a second hand car. We would really appreciate your help in this matter. Sergiy and family
