I was working with this dealership back in September 2024

I was working with this dealership back in September 2024 and was looking for a traverse In within two days of asking, John Cushman found the traverse with everything in the exact color I wanted. I looked all over Columbus for it and couldn’t find it. He bent over backwards to help me now we are going to look for a 2025 new truck And I’m sure we will have him look around and find the truck that we want since he was so helpful with finding us our traverse. Can’t wait till spring, so I can come back there again and check out your line of trucks. Even after I got home, I called him several times and asked questions where to find this or that and he answered me promptly that same day. See John in the spring 😍

By far the worst Service Manager I've dealt with , car

By far the worst Service Manager I've dealt with , car buying experience was great. I do not recommend taking your vehicle to this dealership for any kind of service.

Would not recommend service department, service manager

Would not recommend service department, service manager is rude and couldn’t care less if he has your business. Made appointment a week earlier for 7:00 on Monday morning, truck sat there all day and no one even looked at it.

Bad service all around nothing fixed

Long story short truck went in for service. 5 monthes later and $1,300 later nothing fixed. Ask what bill was, what progress with truck always said call you back never did. Got mad gave them 3 days to get trucked fixed and put back together and Bill ready went in to pay for it didn't know if they fixed it couldn't find bill. Finally got what I wanted was my bill but problem was not fixed bought it to another shop.

Don't buy from them and don't let them work on your car.

Don't buy from them and don't let them work on your car. Jim trenary of Union service department can't fix a vehicle correctly then they don't want to cover their mistakes. I have a 2013 ford that i bought from them .and that they messed up. Two transmissions and a torche converter later and my transmission is still not fixed. First they screw something up when they did a tyranny flush. Then they said it just needed to be reflushed. Then on my way home from dealer light comes on. Take it back said it was torche converter, pick it up from that and few day later tyranny goes out. They replace transmission with one from junk yard. Then I noticed transmission fluid leaking and then transmission goes out again. They replace it with again another junk yard transmission. Drive it home and see a puddle of transmission fluid under car. Take it back and they supposedly fix it and tell me the mechanic that worker on it is no longer with them. Transmission light back on, i bring it back and they tell me the sensor needs to be reflashed. Well transmission is out again and they won't cover it. Guy says they've done enough for me and I should have bought a new car with a warranty. No. Your service department messed my car up and never fixed it correctly. Im so upset. I owe a lot of money on a car that i can't drive and has been in the shop more times than I've made payments. I've been dealing with this since two months after I bought the car last July. What if anything can I do. I feel since it was cover at first and its the same problem then they should have to fix it. I was thinking even if I don't have a legal case maybe a letter or call from someone that has some kind of authority may help. I don't know what to do I'm beside myself . They finally say they will cover it if its only the torche converter so I have it towed to them and its been there for two weeks and they haven't even looked at it and no one will call me back . This is litterly making me sick

Jim Ternary of Union, MO

It was the worst experience in my life to work with this dealership. We were charged for things that we told them we didn't want along with they over charged for the taxes and didn't give us the best interest rate. When questioning them they refused to do anything to help us or refund us.

Dealership needs lessons how their managers treat people

Dealership needs lessons how their managers treat people from out of town that have had their vehicle towed their for service or repair, this customer provided proof, thru fuel test, that fuel was ok,still they would not honor warranty of vehicle thru General motors, they are ????? Questionable, feel liked I am being taken advantage of because I am traveling thru and will not be back again, would think twice about dealing with this dealership

Consumer response

Been almost 10 weeks still waiting on truck, worst service department in the world, service manager needs lessons on fuel test results prove that fuel was 5% to 6% BIODIESEL 94% to 95% ultra low sulfur diesel, well with in the guidelines of general motors requirements for diesel fuel for 2021 gmc, they are denying warranty to pay for this, they want I as the owner to pay for this out of pocket, saying wrong fuel in truck even tho fuel tests proves them wrong, the dealership provided the sample from truck tank to ship off for testing, amazing how science can prove technicians wrong, hopefully time will correct and retraining may help in the future of this type of situation

Avoid this dealership and car

They didn’t even fix the problem! We ended up taking it back to them because it was still doing it. We were told three times they tested it and couldn’t replicate it, even though it does it every time to us. One morning they said they drove it on Hwy 47, went 70mph, the speed limit is 55 on that highway and it was ice and snow that morning so I don't believe them So, we googled it. Low and behold in 5 minutes we had an answer. They have a service information sheet on this exact issue, #18-NA-095. It’s a known issue and Chevy instructs not to do anything to the vehicle and to tell us it can’t be helped. When we picked the car up, we took it with us to show it to them. Scott wasn’t surprised and said that sounded about right, something to that affect. So, after servicing it twice, having the car for days and over $300 we are still stuck with a car that can’t be driven over 60mph if it is below 27 degrees.
