I got a diagnosis, paid $900 bucks to have my car healed, and nothing changed.
I called Firestone and asked for another appointment, but they were booked for the week. When I finally got in, they ran another diagnostic test. I asked the logical question, "Why is my car having the exact same problems that it was having before you fixed it?" The man said, "Honestly, I have no idea."
At least he was honest.
