I went for routine service. I have the the wrap premium coverage. My service advisor told me that everything looked good just needed to have cabin filter changed and battery post had corrosion and needed cleaning. She said it would cost about $50 for battery cleaning. I told her that I would clean it, but did ask her why it wasn't covered. The coverage says "battery to starter". She said you had to buy the battery from them. I said I bought the car from you. It is 2 years old I would assume that the battery still has warranty left and it was just to clean the post. She said she would ask. Never got an answer. I told my service advisor, that we had premium wrap coverage 3 separate times and she acknowledged each time. While checking out with the cashier they wanted to charge me for the oil change. They had to go find out that I had coverage. It was very crowded but all the advisors were consulting with the customers in the hall. It got very loud and no one had privacy. I noticed some people felt uncomfortable. I also noticed for the 5 hours that I was there a up-sale atmosphere/attitude.
