I dropped off my 2015 Charger about a month ago for a service. I had a moisture in my tail light and problems with shifting gears when engine was cold. At first they made a very good impression. Made me feel like I'm leaving my car in good hands. My car was there for a total of 3 days. They started working on my car on day 2. Excuse was their mechanic specializing in engine was not available. And did I mention that I had my appointment scheduled?! What is the point of asking a costumer to drop their car off for service if they know their mechanic will not be available!! When they finally called that my car is ready they said everything is fixed and in perfect condition. I guess that was a lie!! Not even 24 hours later I still had issues with shifting gears. I called a manager to complain about it. His response was "Let me look into it, talk to my mechanics that did your service and will get back to you" guess what?! Its been 2 weeks and I still haven't heard from the guy!! This is a joke! With all honesty.. don't waste your time with them and find a place that will actually take care of all of your car needs.
