I was charged a $149 diagnosis fee, for a CCC drive that I already knew was bad. They told me I needed to replace it. But couldn't tell what was actually wrong. I showed them a service bulletin for which I came in for with the exact problem. Still charged me the fee, when I left with no more information. They stated it was going to take 3 hours, and I had the car back the next day. I got charged for essentially nothing.
