Coughlin Circleville GM

6 months ago, I bought a 2020 GMC Sierra AT4, 85K miles, no warranty. Background, I live 115 miles from this dealership but they had the truck I wanted so I made the drive. There was never any doubt in my mind that I would not go back there for service just due to the distance. On my way home from picking up the truck, the TPMS system said there was an error and was only showing pressure for three tires (no LF). I chocked it up to a bad sensor and as I have replaced these in previous vehicles and know they are not that expensive, I pressed on home as it was too late and I was half way home . This was an intermittent problem until I did my first oil change / tire rotation. I mentioned this problem to the Chevy dealer and asked them to change the sensor. They checked the sensor and it was reading a strong battery signal so I told them to just rotate the tires and I would see what happens. Soon after, this intermittent problem became and consistent issue. The problem was it was showing the same LF tire even though the tires had been rotated and reprogrammed which meant the issue was something else. That Chevy dealer wanted a ridiculous amount of money just to diagnose the problem ($200). That's the history now why I'm recommending Coughlin, a couple weeks ago someone from Coughlin just made a 6 month check up call. I told her I loved the truck and had no issues other than this TPMS problem. I had no expectation of the dealership doing any thing about this, (six months and 7k miles later) she told me she would contact the Service Manager, John Tackett, and have him call me. The next day he did and he told me they would at least diagnose the problem, no charge and see what they could do. Thinking this was looking like it was going to turn into an expensive fix I took him up on the offer. Today I took the truck in and dealt with Paul Lynch, the Service Advisor. Long story short, not only did they diagnose, but they spent a total of 3-4 hours taking care of it at no charge to me. I find it so refreshing this day in age to have a company stand behind what they sold me, I'm just at a loss for words of thanks. Next time I need to buy a vehicle, I will be checking this dealership first, even with it being 115 mile drive. Kudos to John & Paul, thank you both very much!!! Also a shout out to my salesman, Forest, as I had a good experience when I made the purchase. Obviously, I recommend doing business here!!!
