My wife took our new Mazda CX-5, that was just purchased 4 months ago, to have service completed after the first 5k miles. After the service was completed, my wife was on the highway and the car began to shake and black exhaust started coming from the car. She was able to get off the highway and call Towne to tell them the problem and they did not make arrangements to get the car back to the dealership and instead told her that she should either drive the car back or call a tow service and they would compensate her. When she got back to the dealership they told her that they put too much oil in the car and said they fixed the problem. When she was leaving the dealership after this the car started to have the same problems and after she brought it back they said they put too much oil in it a second time. After they fixed the issue the second time, my wife went into the driver seat to find a coffee cup in the cup holder from whoever was servicing the car. My wife advised me that although they offered her a free tire rotation and oil change for the future, she never received an apology from anyone involved.
