Hands down among the worst customer service I have ever experienced IN MY LIFE.
Bunch of con-artists here that when they do something wrong, the only thing that matters to them is: "Did Courtesy Chevrolet make money on it?". If the answer is yes, then you're screwed.
Worse yet, if you have a problem with it and ask them to remedy it, they will not only tell you in person that they won't do anything for you, but they will also call you at your home and remind you that they aren't going to do anything about it, and if you hang up THE DIRECTOR OF CUSTOMER SERVICE will email you to let you know that they aren't going to do anything about it.
It was a mistake going to a GM vehicle. I've driven Fords for years, but I made an uninformed decision to buy a Chevy because of the Volt and Cruze having great gas mileage and my GM card was supposed to give me a discount.
Never doing business again with Courtesy Chevrolet and I'm done with GM all together. Impressive honestly how quickly they managed to lose my business.
