Oh yeah.. back in college, there's one woman who is counseling support for college students and she was having problem with her car. She took it to Hyundai dealership to get it checked and they said they got it fixed. Turn out that it's not fixed. She took it back and for the third time, it's still not fixed. After she heard about me being a mechanic (I rebuild, repair you name it) and she asked me that she was having hard time starting up her car and want an advice. So I take a look and knew immediatly it's the starter gear not catching the flywheel. So, I asked her what did the dealership say that they got it fixed? She told me that it was coming from her window wiper motor, other say it came from bad battery, need to replace and I can't remember what other one...but I got really furious!! Of how dealership mechanic taking advantage of deaf woman of having her keep coming back to get it fixed. She's really in a tight budget, and I was really really furious. So, I helped her to get it fixed by replacing the starter gear and it was only $35 at that time. Then she was very happy that it start up the car like a breeze. Then I wrote a letter to Rochester Newspaper in "Opinions" section, lashing out about this dealership and I even wrote to BBB. Two months later this dealership was shut down completely.
[added: Ha ha, I was re-reading my reply... when I mentioned the words "wrote a letter"...wow... during that time, the "E-mail" technology was not a wide spread yet, but "writing a letter" is long gone.....]
