Took them 1 week to diagnose what was wrong with my Mustang 2016 GT when the wrench light was on. Brought the car to the auto shop near by, the technician plugged it in the computer and after 20 minutes he was able to tell me the issues.
Fun fact: had brought my car here for service the last 3 years, always receive an email asking for my feedback. This time, zero email. Guess they don't like bad feedback.
