Hahahaha... what do you expect, it's not a Lexus (or Benz)? I've actually been told that, too! For complaining about a problem that didn't appear until a dealership screwed my car up.
I guess my standards are just too high. A vibration-free car IS too much to ask for at this price point, I suppose.
And repairs that don't cause new issues with your car is too much to ask for, too. After all, it's just a Ford dealership, not a professional repair facility staffed with competent techs, LOL.
