Brought my car in on Thursday, I still don't have it. They said the car was ready after a few hours, but soon as I pulled it out of the garage it cut off. One of the gentlemen said he told another worker that he didn't feel that the problem was fixed. Called numerous of times for an update no one has returned my call. I was told the car has to be turned over to GM because they can't figure out was going on. In the meantime, I wasn't offered a car due it seems to be a manufacturing problem. Also, I brought the car in for headlights a few times while under warranty and they never could find the problem. Now that it's not under the manufacturing warranty, they said the lights need to be replaced and I'll have to pay out of pocket. I don't understand why they didn't figure it out while under the warranty. I'm VERY disappointed in the service I've received.
