Brought them my sisters Chevy Cruze 2014 I had recently got in the ocean with my key in my pocket and now the car no longer will start I had my car towed to the dealership where I told him I'll need a new key that I got my key wet and now it's no longer working. Clifford, in customer services, guaranteed me that it was not the key fob that it's something else with the car so they charged me $150 for a diagnostic for him to call me back the next day and tell me it's the key fob now they told me it's going to be $226 so I took it to him and I went to pay and the price said $252 so there's another lie. What started out as a simple $85 fix led to a bunch of hassle and ended in a $250 fix. Went ahead and paid it just to get out of that dealership it is the worst business I've ever done with anyone and in my opinion they are modern-day crooks and while I was in the waiting area another lady next to me I had overheard her conversation and she was having the same problem where they told her a price of $400 and then tried charging her five hundred and something dollars for the repair but I kept listening and they brought it down to the 400 they agreed on the invoice which they did not do for me because I am not one to argue over nickle and dimes. I recommend staying far away from this dealership!!!!!
