Good afternoon. I had my car in for service ecently. The water pump went out, which is amazing since it should have lasted 10 years! However the service writer questioned if it was covered under powertrain! First sign of trouble. After it was determined that it was covered I was called and they tried to sell me on overpriced, unrelated service. Since when does an in cabin air filter have ANYTHING to do with an engine? At least the other questionable preventative maintenance items were engine related. Once I explained that no I will not pay 90 dollars for an in cabin air filter and that I was on top of the other issues I could hear his attitude change. Not being able to actually prove he had an attitude the conversation ended without provocation. I was called back later to be told that I needed two hoses at a cost of 115 dollars! Again 4 year old parts. So I said that I wanted to see the parts when I came in. Although I have a right to see them I did not say that to him. The attitude he had before was no longer there and I trusted that I would see them. So to make a long story short they refused to let me see the parts. Based on the fact they tried to sell me on unrelated service then would not let me see the parts they claimed I needed I have no way to beleive anything other than they ripped me off. Of course NOTHING was done to rectify the situation. At this point what can I do? Should I report this Stealership's name on the forum? Is there a number for GM customer care that I can call? I can't just sit back and do nothing as long as I have that doubt in my mind. All it would have taken is showing me those two hoses and no issues whatsoever. Now, that Stealer loses my business and GM might too.
