They need to do the warranty repairs, but I am not sure why you would want them to given your current relationship.

You bought a used vehicle, and they are fixing it. The problem you had could have happened to any vehicle, it isn't specific to the one you bought.

You used the survey to express your frustration, and it cost them big time. They are just saying you should probably go somewhere else given your attitude. I agree. If you don't want to work with them, they are better off without your business. With the qualifier on the warranty work, which is an obligation, if it was my dealership I would suggest you find another service outlet as well.

No, I am not feeling you here.
