AutoNation Cadillac Corpus Christi

I’m really disappointed in the Cadillac dealer in Corpus Christi. My car is new and under warranty. It was making a weird noise so I called to get it in. I was told that I would have to drop it off and it takes 4-5 days for a diagnostic. I said that’s fine I’ll take a loaner car. They said they don’t do that I have to rent my own car!!! I told them my car is new and under a full warranty so why would I have to rent a car. So I rented a car, $450! I go to pick my car up when it’s ready. The drivers floor mat was black from workers shoes and be carpet is now stained black!!!! The service guy then tells me it was some kind of fluid that I needed and it could take 3-4 times to get the levels corrected!!! I said so I just need to call and they will know what’s wrong then? He said no!! I need to bring it in and get a diagnosis like I did the first time!!! So every time I need to bring my car in I have to rent a car!!! Before we moved to corpus, we looked at what car Dealers were here so I could get good service! I’m so annoyed with Cadillac that I told my husband I want to sell my car and get Mercedes or Tesla cuz they have wayyy better service!!!
