I dropped off my 2013 Buick Regal in order to fix a flex fuel sensor that had caused the engine light to come on. I dropped if off just before I left the country for a couple weeks, they had two weeks to fix it. The whole time I was in Canada, I hadn't received one phone call saying the vehicle was done, or they had an issue, etc. When I got back into the country, I gave the dealer a call and they had said they didn't have my car. They had no record of me dropping the vehicle off whatsoever. A lot more phone calls later, they found my car and said they ordered the replacement part and it still hadn't arrived, but it should be done that week. Thursday rolled around and I went in to pick up my car. The engine light was still on, so I went right back into the service garage and told them. The guy told me that the mechanic must've forgotten to reset the light. No big deal, but you'd think it would reset itself had it been fixed. Regardless, they reset the light for me and I was off to my house (less than 5 miles away). One thing to note here, I received zero paperwork for the service they "performed", they said they would mail it out to me. It is now ~6 months later and I have yet to receive any paperwork for the reason that follows I presume. Before I got home, the service engine light came back on. I ended up taking it to the Chevy dealership down the street who fixed it literally the same day I dropped it off. I had them look up the service record that this dealership wrote up. Apparently they wrote that they could not duplicate the issue and did absolutely nothing to it and lied straight to my face saying they did fix it.
Prior to this visit, I also went in to test drive some new vehicles. I was not allowed to test drive any cars for some reason. My only guess is that it's because I looked too young to afford one, but honestly I do not know for sure. I was just surprised that I wasn't allowed to drive something.
