McKinney Buick GMC

I saw a listing on Autotrader of a 2023 Silverado ZR2 that was priced out as a certified vehicle. I test drove and liked what I was buying knowing it had additional warranty due to it being certified. Purchased the truck and bought an additional extended warranty to be a 6 year/100000 mile warranty total. Four days later I get a call from the dealership saying I needed to come in for some closing papers on the truck. When I showed up they informed me that they couldn't certify the truck due to a recall on the motor. They canceled my initial certified wrap warranty and moved me into a similar warranty to help with that. My issue is that I paid more for the value of a dealership certified vehicle and not the value of a dealership used vehicle. Maybe I'm wrong in this thinking but there is a difference between the two products. I paid for the higher level product and ended up with the lower overall.

Great service and excellent customer service super detailed when explaining the repair or items coming up for repairs

I was able to get an appointment with the service department on the same day.

Rob and Chris always professional, always hospitable. I’ve known Rob for years and he has always taken care of us above and beyond. Chris was extremely friendly and kept me in the loop throughout my service appointment. Service like this is a lost art. Very grateful and happy with the GMC Mckinney service department staff. Thank you

Worst experience from purchasing to warranty. They say they will call back and won’t. They damaged our vehicle while in their possession and refuse to take claim. The GM was supposed to call and hasn’t. I would never take a car to them to have windshield washer fluid added. Now we have to go the legal route and will push for everything. DO NOT BUY OR SERVICE WITH THEM.

Thank you Joshua, for a great first time experience at McKinney Buick GMC service department.

Josh Moreno is a great service rep, he always gets the details right! I will return!

In the service area, brandy does a great job. She is always very responsive and prompt.

Dishonest, Shady, and Overpriced – Buyer Beware I’ve been servicing my vehicle at McKinney Buick GMC since 2021, but ever since my prepaid service contract ended, things have gone downhill fast. The level of dishonesty and scammy behavior I’ve encountered from the service department over my last few visits has been beyond frustrating—it’s infuriating. It started months ago when they told me I needed a new air filter and cabin filter. Problem was, I had just installed a brand-new K&N air filter the day before. When I called them out, they admitted they didn’t even check—it was just a generic recommendation based on mileage. I let it slide since they were honest when called out. Fast-forward to last week, they tried the same thing again. This time, they told me they checked my filters and they were dirty. I knew for a fact they weren’t—I had cleaned both myself recently. I pointed out that there are clear stickers under the hood and inside the glovebox stating they’re K&N reusable filters. When I confronted the advisor, she backpedaled and admitted it was another mileage-based recommendation. That’s not just lazy—it’s deceptive. But it gets worse. After declining the unnecessary filter replacements, I received a text with a laundry list of overpriced “recommended” services: Transmission Flush: $269.95 Coolant Flush: $195.95 EFI Service: $220.00 Throttle Body Cleaning: $89.95 Cabin Filter (again): ~$80 I declined them all but saved screenshots for reference. So I could remember what to get done in the future When I went to check out, I noticed they added a $20 tire rotation I never asked for. When I told the advisor to remove it, she insisted it was done. I stared her down and told her that wasn’t possible—my truck has brand-new tires with less than 25 miles on them, and the wheel lock key was secured in a locked safe inside the truck. I asked her how they managed to “rotate” tires without the lock key. She said nothing other then I will remove it and quietly removed the charge. No apology. Just got caught. Despite all this, I came back a week later to get the transmission flush—because it was due. I asked to confirm the price I was quoted last week ($269.95), and was told by Raul it was actually $700. I showed him the screenshot I took of their own system with the quote. After some back-and-forth, Raul went to his manager and got the price down to $399. While still $130 higher than what I was quoted in writing, I agreed—mainly because Raul was the only one acting like a professional and trying to make things right. He even offered a free detail and ceramic wax to help smooth things over but I did turn it down for the moment becasue it was late in the day and he said I could come back and get it at any time on them for my troubles. I appreciated that and told him as much. If I could separate Raul from this review, I would. But then it fell apart again. When I went to pay (different advisor then Raul), the bill was $450+tax, not $399+tax as quoted. Why? A mysterious “disposal fee” / "Misc charge" was added. I told the person at checkout (who clearly didn’t care about customer service) that it wasn’t what I was quoted, and he just shrugged it off like it was my problem. He wouldn’t remove it, wouldn’t explain it, just handed me my keys like “take it or leave it.” So here I am—writing the review I hoped I wouldn’t have to write. Summary: Tried to sell me parts I didn’t need—twice. Billed me for services that were never performed. Only removed them after I pointed out the impossibility of them being done. Gave misleading price quotes that mysteriously increased at checkout. Showed zero accountability unless caught red-handed—with screenshots. Clearly operate with a business model built around upcharges, deception, and apathy toward the customer experience. McKinney Buick GMC's service department should be ashamed. I’ve been a loyal customer for years, but never again. I encourage anyone reading this to be extrem

Went in for an oil change?the process was quick and smooth. Really appreciated the excellent service. Big thanks to Elliot for taking care of everything.
