Unexplainable how disappointed I am with the service of the mechanics at the Chevrolet dealership. It seems like there in just a rush get your car out of there that they don't properly diagnose it. I had to go back three times now for the same issue within a couple of months. I spent over $3,000 trying to get it fixed and it still is not fixed. Took it to another mechanic locally and they did the proper test.
