absolutely systemic... When I asked my dealer to balance a tire because I had a steering wheel vibration, he just rotated them and the vibration clearly moved to the back. Also overfilled my oil by almost two quarts, (which is not acceptable to me). When the underpaid office assistant called on "service followup", and wanted to know what they could do to make it right. I told them they could reumburse me for having Discount tire do the balance that they should have done. She said, no problem, the Service manager would call me back. Never happened. I'm done with service there.colin said:Here is a follow-up to my earlier post. The very same day that I made the earlier post my dealer called me to see if I would rate them "Completely Satisfied" on item 16 on the GM Satisfaction Questionnaire. I replied no and explained what happened to me on my last visit. The lady I spoke with said that she would send the details of my experience onto the Service Manager and have him call me to see what they could do so that I would rate them as Completely Satisfied. Here's the kicker though - no one has called me yet. Talk about a complete lack of follow through. Seems that this is a systemic problem at that dealer.
