Sean Eddleman was very knowledgeable and courteous . He answered all my questions and took care of my Sierra. The waiting room was clean and they provided coffee and popcorn . Its nice that they have two areas, one with a television and an area where you can read or get work done.

Jeff (and the rest of the crew, Jesse, Justin and the other man whose name I don’t know) are always spot on with a smile and a welcome. They cover all the bases when I bring in my Terrain. I really appreciate their listening to my concerns and how I feel they go through with a fine-tooth comb in searching for any issues. This is my second Terrain. My first Terrain I gave to my son because he and his wife needed a family car. I did not need to shop around, because I knew I wanted another Terrain. Now my second Terrain has some issues and I need to build trust again that it won’t break down again. Having said this, when I’m ready for another car, it will be a Terrain again. Once a Denali Terrain owner, always a Denali Terrain owner. Kudos to Jeff and staff. P.S. I love how the cashier always makes fresh hot pop corn (and keeps the pop corn machine clean), and the new fish tank is a nice touch as well.

Since purchasing our car at hardin I have been coming back to service my car there also. I am always happy with the service done on my car, we love the customer service at the service side and I am happy there is a play are to entertain my little ones. The only complaint I have is that every single time I have gone the customer service has never been pleasant at the payment window. The lady always looks like she mad. Not really the customer service I like to be getting when paying for a car service.

I am immensely grateful for the Hardin GMC/Buick team within the Anahiem Auto Center for the impeccable customer service and experience, which was without a doubt easy, efficient, and stress-free, from start to finish for the vehicle purchase. The entire process was conducted smoothly. I look forward to future business and will also ensure to send referrals. Jesus, from the sales dept. was professional, kind, transparent, and thoroughly answered my many questions. His jovial demeanor and patience were admirable. I truly appreciate him! Thank you Jesus - you are absolutely amazing, and you established great rapport with me from the onset of my arrival, and you helped me navigate my options and/or the barriers. You actively listened to my needs, concerns, and understood my situation without judgment. I felt liked you truly cared. We had a few great laughs too (which I needed more than I knew); it was great and added to beyond customer satisfaction and appreciation. All the staff that I came in contact with the day of purchase were extremly friendly, nice and helpful. Gio, (can't recall the dept.) thank you for working with me, I am appreciative of the clarity you provided and transparency. Brian from Finance, I enjoyed our conversation and laughs. I learned a lot from you. Thank you for your kindness, sharing knowledge, and working with me- I appreciate you. There's another person that was extremely kind and checked on me often, (however I inadvertently did not get his name) in addition to checking on me during the process, he asked if I had eaten and if wanted anything as he was headed out to grab something to eat - it's the little things that are impactful to fostering positive customer interaction and a customer feeling welcomed and comfortable- thank you and I appreciate you as well.

Driving back from Arizona on Monday the change oil light soon came on. I called service department late in the afternoon that same day and spoke with Jesse. He was able to arrange an early morning appointment for the next day. I mentioned to Jesse that I was having trouble with cruise control, so after oil change was done, we went on short drive to make sure cruise control was working. Jesse is always helpful and friendly as are any of the other Hardin employees I come in contact with. We are pleased with the service we always receive.

I used the GMC app. Harden was willing good to me due to me make changes to the date. One area that continues to be an issue is when my truck is returned every time the hub-cap plastic lug nuts are not properly fastened. I am aware that they do come loose I look every day. But leaving the shop by the time I get home many are almost off. Next time I will check them before I leave dealership. Over all I will continue to use Hardin GMC.

Justin in the service department was excellent. We tried to get GMC to cover the display problem I’ve had for years on my GMC Sierra, but they refused. That was disappointing. Because it was a $1000 fix. I’m a retired Vietnam nam vet and $1000 these days is money I could use for other things so I decided to pass on the fix and live with it. Again, this is no reflection on Justin in the service department, he did everything he could I believe. Still disappointing.

I have three dealerships closer to me for service, but I decided to go to your dealership since it had the best service reviews. Not a fan of your service department not sure I will ever go back and definitely will not recommend to anyone else. I brought my SUV in for an Oil Change at 7:30 am and was told I was first in line and should take long, since I planned to wait. My SUV then sat for 40 mins without moving from where I dropped it off. I did not get my SUV back till 10am, two and a half hours for an oil change?? Next issue: I receive a coupon in the mail for a $79 oil change, which I showed to the service adviser when I check in, and he did not say anything about not valid for my SUV. When I paid the bill, I was told there are no discounts for an oil change, very disappointing on the communication by the service writer. And the biggest disappointment was the issue with my Automatic High Beam Assist that was not working. In which the service writer told me there is no on/off, you just have to meet certain conditions, and it will turn on. I told him that I have met all the conditions listed in the handout he gave me, and it still does not work. He told me there were not any error codes and there was nothing wrong with the system and argued with me for 10 minutes that I have not met the conditions required. When I got home, I did a little research and found out that all you have to do is flip the high beam twice in two seconds when is dark, and the Auto beams come on. Why don't your service techs and service writers know this??? This was the worse experience I have ever had at a dealership.

I called after being told by Firestone Complete Auto Care that my GMC Terrain had a collapsed motor mount. I was given an estimate for repair, but decided to call Hardin Buick, GMC, where In purchased the vehicle, for an estimate. Sean took my call and provided me a rough, but good idea, what that type of repair would cost. Being lower than Firestone I made an appointment over the phone; the service dept. was busy so suggested I come in on Monday a.m. I took the Terrain in, had the repair done, even lower cost than original phone estimate, and was back on the road that afternoon.

Everything seemed fine. The DEF was not topped off like you said per your flyer. After waiting 2 hours I found this out. I told the service rep to take the truck back in and add it. he did, but it wasn't topped off. He said as the truck moved around the gauge would fill up. That was BS, now it's half empty. Very discouraging!

I came to the service department without an appointment because an oil level low indicator light came on. I agreed to wait while my car was checked out and an oil change completed. There were 3 cars ahead of mine for oil changes with scheduled appointments. I was updated periodically on my probable wait time, told how progress was being made with the other cars, and treated with courtesy & respect - which is always the case for this dealership.

I had my car serviced (30,000 miles) on a Saturday and by the next Wednesday something was wrong. I took it in but there were no appointments available, so I left it. My car was there for three weeks before I got it back. What I think is ridiculous is that I spent a lot of money buying the car from Harding Buick because it was highly recommended by a trusted friend (my car payment is more than my mortgage), but I feel taken. There should have been a loner car available! Three weeks of car rental, even at a discounted price, is just bad form! I was not kept in the loop as to what was going on - I had to call several times and when told that I would get a call back, did not. I have in the past been satisfied with the service in the past, but this time it left a bitter taste in my mouth.

I have owned GM products for over 20 years continuously and have experienced both spectrums of "service" - good and bad. For me, I must be able to trust my vehicle and therefore, my service location. I left my past dealership for service because following a change in ownership, they placed a new Service Manager who believed the "spreadsheet" was more important than providing reliable and high quality service. The quality Advisors and Mechanics starting leaving, being replaced by new, inexperienced (and likely less expensive) staff. Customers started being treated like numbers and concerns were ignored because "service knows better". I have seen this happen MANY times in my GM ownership. However, Hardin and Sean Eddleman are a welcome breath of fresh air. He is experienced, understands his job, and does what is necessary to provide true service - great, honest, communication, a dedication to solving problems, and taking the time to truly understand the issue. I don't come to a dealership for service to get the lowest price. I come so that I can have my vehicle worked on by brand "experts" who should know more about my vehicle and its known issues/remedies more than anyone else! Sean and Hardin clearly fall into this category and as long as that approach remains, you will have my business and full endorsement!!!!
