Mercedes-Benz of McKinney - Service & Repair Facility

Excellent service experience! I needed to replace the auxiliary battery on my 2019 GLC PHEV SUV, and although it was a special-order battery, the dealership had it available by the very next morning and completed the work quickly. A special thanks to the service supervisor, Jesus, for arranging a loaner car while my vehicle was being serviced. His professionalism and thoughtfulness made the entire experience smooth and stress-free. I truly appreciate the outstanding customer service and highly recommend this dealership!

I scheduled a service appointment because my Mercedes indicated that it was due for Service A. When I booked the appointment, I was provided an estimate approximately $399 for the service. After arriving at the dealership and handing over my keys, the service advisor added several additional services—including spark plug replacement, differential fluid service, and other items—which increased the estimate to more than $1,270. My issue is not that additional services were recommended. I understand that dealerships should identify and recommend maintenance items that may be due. The problem was that when I specifically asked if I could proceed with only the Service A that I came in for, I was told that I could not. I was informed that all of the added services had to be performed because the vehicle supposedly showed Service A2. I asked for clarification more than once and received the same response. Fortunately, I chose not to authorize the work and left. After checking my vehicle myself, I confirmed that the dashboard clearly showed Service A1, not Service A2. I also reviewed Mercedes-Benz maintenance guidelines, which confirmed that Service A1 primarily consists of an oil and filter change, fluid checks, and a multipoint inspection. What concerns me most is not the recommendation of additional maintenance items, but being told that I had no choice and that the dealership would not perform the requested service unless I agreed to all of the additional work. As the customer, I should be able to decide which recommended services to approve and which to defer. I have owned and serviced multiple luxury vehicles over the years, including Mercedes-Benz, Audi, Porsche, and Acura, and I have never experienced a service department attempting to force additional maintenance in this manner. This experience felt misleading and not customer-focused. Very disappointing.

I normally don’t write reviews, but the level of care and professionalism I received from Nathan at Mercedes‑Benz of McKinney absolutely deserves recognition. After dealing with two other Mercedes dealerships — Plano and Dallas — where the service, attitude, and professionalism were honestly disappointing, I was close to giving up on Mercedes entirely. Our GLB 250 4Matic AMG package had been overcharged, under‑serviced, and important items were overlooked. Plano in particular left us feeling dismissed, rushed, and unheard — especially regarding my health conditions, which require a little extra patience and clarity. Then we met Nathan, and everything changed. From the moment we arrived, he was kind, patient, and genuinely understanding. He took the time to listen, explain things clearly, and make sure we felt comfortable. He didn’t brush off our concerns — he actually showed us what the previous dealerships missed, what should have been done, and what we were overcharged for. That honesty alone meant the world to us. Nathan treated us like people, not transactions. He respected my health limitations, communicated with empathy, and made sure we understood every step. For the first time in a long time, we felt like our Mercedes was being cared for properly. Because of Nathan, Mercedes‑Benz of McKinney restored our trust in the brand. He is exactly the kind of service advisor every dealership needs — knowledgeable, professional, and genuinely good to people. If you’re tired of feeling ignored or upsold, go see Nathan. He’s the reason we’ll continue servicing our GLB 250 at McKinney from now on. -Jacob and Michelle

I recently purchased a Mercedes-Benz and had an outstanding experience from start to finish. I especially want to recognize Sunny (Shams Hashmi) for going above and beyond throughout the entire process. Sunny took the time to walk us through every detail — from features to pricing — making sure we fully understood everything before making a decision. He was incredibly patient, transparent, and genuinely focused on helping us find the right fit rather than just making a sale. What stood out the most was his dedication — he stayed late into the night to ensure everything was handled smoothly and that we left completely satisfied. That level of commitment and professionalism is rare and truly appreciated. If you’re considering a Mercedes-Benz, I highly recommend asking for Sunny. He made the experience seamless, informative, and enjoyable. Thank you again for such a great experience!

Mercedes of McKinney I've used your service department several times in the past and have been pleased. I'm staying in Emory Texas with family therefore considered using the service center in Tyler, their quote for service B was $1300. However after asking if they were certified to handle a Mercedes recall I learned they were not. Which lead me to return to McKinney for service. However I was disappointed to find out your shop wouldn't be able to accommodate the recall either. I also requested my front tires be rotated to the rear and learned your shop wouldn't be able to accommodate this either. I also have messages on the DIC indicating Trailer light problem and Turn signal problems. However since my RV is a class C and not OEM rear lights all your shop could do was clear the error, which came back before I left the parking lot. The routine service B was performed to my satisfaction although at $3042.89 it was considerably higher than what I was quoted in Tyler. I would rate the routine service B at 4 with a negative comment about the expense. As far as the tire rotation, the Trailer light messages and ability to deal with the recall, your dealership did not meet my expectations and I would rate those issues as 2 and only that high because Nathan Myers, was able to explain why your service center were not able to accommodate those issues and did so in a very professional and polite manner. I appreciated his tact and professionalism. Your service center charges a premium for what could be high quality professional service and did not meet my expectations. I would think you'd want to improve in the areas I've pointed out, which would then justify the premium service rate charged.
