McKinney Buick GMC

Stay away from this dealership. I never leave bad reviews publicly, but this experience was a nightmare. First, Patrick in financing flat out lied to us that all of the warranties a I never leave bad reviews publicly, but this experience was a nightmare. First, Patrick in financing flat out lied to us that all of the warranties are refundable. The Exterior Care Warranty was NOT refundable. We verbally verified with Patrick several times that all of the warranties were refundable and he assured us they all were. That was a lie. When we tried to reach out to the dealership to remedy this, they said "It's not refundable" and did nothing to rectify Patrick's lie. I see in other reviews on Google he has done this also to other people. We were happy with our salesman but, when we got the car home finally (long story of a back-ordered rear-differential debacle that started making noises as we drove off their lot), our local mechanic found the rear struts had been leaking for quite some time and were badly in need of being replaced. This was NOT disclosed at the point of sale and should have been obvious at their inspection when they are listing the condition of the used vehicle. One of the dealership's sales pitch points is their rigorous, competent inspection they promise, and this needed repair was not disclosed and will cost me over $1,000 to fix. I have several complaints about the customer service experience with McKinney Buick GMC, but my main complaint is being lied to about the warranty's refundability, the car's mechanical integrity not being assessed or disclosed properly, and the absolute headache of working with any management who would shuffle us off to other departments and say it "wasn't their problem" or "their hands are tied". We were even told at one point by a manager we needed to "take personal responsibility for buying a high mileage vehicle" during a phone conversation when we called for help for rectifying our situation of being without our purchased vehicle for such a long time (3 months) when our vehicle displayed major problems upon driving off the lot and we had to leave it there. They offered no loaner, no option to return the car and source a different one, or option to have our local GMC dealership make the repair (we bought this car from out of state) so we would not have to keep driving back to TX. They would not alter their protocol for our situation of living out of state and would not skip the initial step of a flush before ordering the necessary part, resulting in a radically extended wait time (3 months). The flush fluid and the part were both on back order, so instead of being put on the right list for the part in a timely manner, they made us wait for back-ordered flush fluid for a treatment that would not fix the failing part. After 2 weeks of no progress, we personally called around to neighboring GMC dealerships who had plenty of fluid to sell to McKinney Buick GMC, and that is how we found the fluid for the dealership. They flushed the rear differential and told us it was fixed. We drove to TX to pick up the car only to find out the fluid flush did not get rid of the noisy symptoms. After much back and forth they agreed to order a new rear differential. This circus of protocol delayed the resolution significantly for us. We had strongly contended for a replacement for the failing part to begin with. Ultimately, the dealership did replace the defective part, but only after 3 months of waiting for the part to come in from a national back-order (and the first rear differential part being "lost" during shipping and we had to be put back at the bottom on the national back-order list for another one). We were stuck with paying full interest, insurance and payments for 3 months on a car that was out of service upon purchase, with no transportation solution or reimbursement option offered to us.

Less than two weeks of ownership, we discovered major issues with the motor mounts and the control arms that hold the engine in place. We also found rust on the spark plugs and on the battery terminals. Dylan Christian the manager told us that is what we should expect from an older used car. He also said they were not willing to do the right thing and a refund/return would cost them money! Worst customer service experience of my life! He was condescending and rude! More

First maintenance visit today and went well. For an oil change and car wash I waited an hour and half which I think is a bit long to wait. But other than that it was ok.

First time to dealership. Brought it in for service, recall items and to diagnose the infotainment system that had quit working. I dropped off on a Wednesday and left messages Brought it in for service, recall items and to diagnose the infotainment system that had quit working. I dropped off on a Wednesday and left messages checking on status Thursday evening, Friday morning and Friday evening to which no one replied. I finally got a call back on Saturday letting me know it was done. I pick it up and the infotainment (radio, nav, seat controls etc) was not even looked at much less fixed. It wasn't even on the paperwork. I was told to bring it back the following Saturday and they might be able to get to it. I've since taken it to another gmc dealer who is finishing the warranty work. Extremely disappointed. More

I made an appointment at 1:00 for an oil change and to check my cars fluids. my car was finally taken back at 2 o’clock. I waited another 45 minutes and was told it was going for the car wash and should b check my cars fluids. my car was finally taken back at 2 o’clock. I waited another 45 minutes and was told it was going for the car wash and should be ready soon. I waited another 30 minutes and went to ask why it was taking so long for the wash. Their employee finally went back to check on it. Finally at 3:15 my car was brought out. I will not be taking it back to them. Thank goodness I didn’t have anywhere else to be. More

The service department did a fantastic job getting my Buick Lucerne running like the day it was made. Who knew that shock made such a huge difference? Buick Lucerne running like the day it was made. Who knew that shock made such a huge difference? More
