They over charged me and still gave the wrong diagnosis of my vehicle. I went in to get my car checked out because a weird noise was coming from it. After holding my car for 6+ hours they told me there s an air leak in my exhaust. They asked if I would like to get it fixed and I told them it s cool because I m going to go get a new after market system installed anyways. When I got to exhaust authority (to get my after market exhaust system installed) they examined the weird noise and check the papers that Chevrolet gave me and told me that they lied about what was on the papers . They were even nice enough to show me how the system they put on the papers was working smoothly and that there was no air leaking coming from that portion of my exhaust system. This all took place within a matter of minutes and they didn t even charge me. I do not recommend you to take your car into this Chevrolet unless you want to just waste money.
