Before I talk about my experience with John Thornton Buick GMC yesterday, I need to take you back 6 weeks. My wife and I were looking for a vehicle that would comfortably seat our family of five including two tall teenage boys. We narrowed or search to GMC Yukon XL, Chevy Suburban XL or Ford Explorer MAX. After looking at several, we found a Yukon XL at John Thornton Buick GMC in Carrollton. I called to make an appointment for July 8th. When we arrived, no one knew about the appointment. We finally were helped by Jon Day. He helped us look at the vehicle and arranged for a test drive. During the test drive, the transmission did not feel quite right, but Mr. Day assured us that the vehicle had been thoroughly inspected by their service department. We felt like the price was a little high, so Mr. Day called in his used car sales manager, Glenn Pierce. Mr. Pierce dropped the price a little and we agreed to the purchase. Because the transmission did not feel quite right, we asked for an extended warranty. We met with the Finance manager, Joanna Thigpen, and communicated that we were looking to purchase an extended warranty. Mrs. Thigpen insisted that it was not worth buying the extended warranty. Based on this, we reluctantly signed the warranty opt-out. It was a little strange to sign the opt-out when we were the ones pushing for a warranty. Normally, car dealerships put a hard sell on extended warranties, but not in this case. We now know why. The first thing that happened was a failed TPMS sensor within a day of the purchase. I contacted Mr. Day via email but never received a response. We also started noticing the transmission was getting worse. I called to schedule a diagnostic check, but in the meantime, my father fell ill. I had to cancel the appointment as my father was placed in hospice and then passed away. I finally was able to reschedule the diagnostic check for yesterday at 9:30. Since we live about 45 minutes away, I decided to work from the customer lounge. Four hours later the diagnostic was completed. I was informed that the transmission needed to be replaced along with the motor mounts and 2 TPMS sensors. Since I only recently purchased the vehicle, I was instructed to speak to Mr. Day to see what the used car department could do to cover the cost. I spoke to Mr. Day, who produced the warranty opt-out to show that I had declined the warranty that they "offered" and that there was not anything they could do. I asked to speak to Mr. Pierce. Mr. Pierce also stated that I had declined the warranty but he "would do me a favor" by having the repairs done "at cost" and throw in $1,500 toward the cost of the repairs. With all of that, the repair estimate was still more than $6,000. After several hours of back and forth with Mr. Pierce, it became obvious that the dealership was not going to make this right. So, we decided to post a 1-star review. Mr. Pierce immediately confronted me about the review. I explained that he knowingly sold me a damaged vehicle and asked to speak to the General Manager, Zach Robinson. While walking across the parking lot to speak to Mr. Robinson, I continued to express my dissatisfaction with how we were treated. Mr. Pierce told me to wait outside in the heat. I waited about 2 minutes and then walked inside. Mr. Robinson was with another customer and shut his office door. While I waited, I had a conversation with a nice older couple that were there to purchase a vehicle. I explained how we had been treated and suggested that they have an independent mechanic check out any vehicle they were considering purchasing. Mr. Robinson immediately came out of his office, was very irate, and told me to leave. While Mr. Robinson was walking with me to get my vehicle from the service department, Mr. Pierce called 911. Teh service department conveniently could not find my key fob until the police showed up. As soon as they brought the vehicle, I left. I write all of this to express that I will never buy anything from any John Thornton dealership again. If you search you will find many stories just like this one. read more
