Absolutely Horrible repair shop to do business with. I cannot speak for the sales department because I did not purchase my vehicle from there, this review is specifically for Gwatney GMC "Service" Department. Gwatney will quote you prices for repairs when nothing is wrong with the vehicle. Ended up with shock and strut parts, that cost roughly $250, that I was told needed to be repaired on my car. Got a second opinion, and that was not the case! Shocks and struts were just fine on my vehicle. Needed a transmission flush, a normal service that has to be performed on the vehicle and the "technician" failed to put enough transmission fluid in my car. This could have caused major damage if I didn't pay attention to the faint rattling noise coming from my hood. Also, careless mistakes such as leaving the cap off of the oil reservoir after draining the oil, is an amateur mistake that I don't expect "properly trained" technicians to make. They called themselves replacing the thermostat, and the engine went completely hot after a few days. They said the end part of the hose was shot. Interesting part about this is that the hose is physically removed by from the radiator by the technician when repairing a thermostat. I was able to pull over at a repair shop, lucky for me, that was able to identify the problem without even having to put a hand on anything. There it was, clear as day that the hose was no longer attached to the radiator. When the dealership got the vehicle, I was then told that this occurred because the hose piece was "worn." What trained mechanic puts a worn out hose back on a vehicle?? Instead of the service manager accepting responsibility for the mistake, he tried to blame it on a "worn radiator hose," instead of maybe taking into consideration that it may have not been attached properly, nor securely. Additionally, the service manager, David Sample, tried to go back on an agreement that I'd only have to pay for half of the cost of the radiator.....if Gwatney was not accepting any responsibility for the issue I'm not sure why they would propose that I don't have to pay for labor or any other associated costs for the repair except if I only pay half for the supposedly now damaged radiator? The most unprofessional part of the event is when Mr. Sample initially wanted me to only pay for 1/2 the cost of the radiator. When I came in this morning to pay for half of the cost of the radiator, and pick up my vehicle; he was angry because I had filed a complaint due to the lack of professional service. I had to get the cops involved. The sad part is that all of this happened and the service representatives were all aware of exactly what was agreed upon the day prior. I asked the "Service Advisor" Jonathan Manek, about the higher charge twice, and he did not provide an answer until I got the cop involved. Previously he kept saying I needed to speak with "Mr. Sample" about the price difference, but began to sing a different tune when the cop showed up. The price of the radiator on the printed receipt that was handed to me was $300. However, there was a yellow sticky note that had "Cust-$198," nearly 2/3's the cost of the radiator on the receipt. I was told I only had to pay half the price of the radiator by the "Service Manager," Mr. David Sample. After about 10 unnecessary minutes of both Mr. David Sample and the "Service Advisor" Mr. Jonathen Manek going back and forth with me over the cost discrepancy that I was originally quoted, Mr. Sample caved. He stated that he was aware that I contacted GM, and I'm not sure if that is possibly the reason why he decided to renege on the original agreement. I kept the receipt with the yellow sticky note attached that proves their outright dishonesty and deceit, and how they are perfectly okay and willing to try to get over on customers. I highly advise that anybody who wants to maintain their vehicle in working condition does NOT conduct business with Gwatney GMC. They are bad for business, and their lack of good service and outright lack of professionalism is reason enough for me to never ever let these people near this vehicle or any other vehicles I may purchase in the future. This business is being reported to the Better Business Bureau, and there was a complaint made to GM. Please spare yourself the trouble, and go to a reputable service and repair shop. I don't ever want any customer to have to go through what I went through at Gwatney GMC "Service" department.
