I came in for a $200 AC issue on my Santa Fe. When I left, after it was "fixed" the transmission shifter wouldn't shift. They took my car to a transmission shop and told me it would need to be rebuilt for about $1600, this took a about a week to find out. The day I came to pick my car up because it was totaled, it was miraculously able to start shifting again, after I said I wouldn't pay the $1600, and I had the triple A tow truck with me.
I can't trust them with my car, I was about to be out a fair chunk of change for something that wasn't broken.
