Comment : Jose Campos is amazing! I really appreciate his thoroughness and professionalism. He has a wonderful way of offering additional services without sounding 'salesy'. The car was returned clean, and the overall experience was very nice. Please let Jose know how appreciated he is! Thank you.

Comment : Went to bring in my Hummer EV for service as scheduled then told me they wouldn’t be able to get to it for 2 weeks+. Terrible customer service not willing to help or find another dealership to help me out.

Comment : It feels like our truck is being held hostage at this point. Needing to do the diagnostics went from 4 days to not having a technician assigned to it until after the 7th day! We have had our truck serviced here ONLY since 2014....what has happened? Icing on the cake, I'm on a "waiting list" for a complimentary vehicle. That tells me there are other customers in the same pickle.

Comment : Purchased one car from this dealer, Cadillac Escalade. The purchase was fine. There were no bad experiences however , purchasing a vehicle is easy but service is most important. It’s what happens after you buy the car and how they treat you. I have had the best experience with RAY in the service department. He’s very responsive takes care of his customers and I highly recommend him if you go here I have purchased other vehicles at other dealers and continue to go back to Simpson because of him.

Comment : I'm extremely disappointed with the service department at this dealership. While my truck was in their care, it was left out front in a high-traffic area and ended up getting hit by an Uber driver. This situation could have been avoided with better handling and awareness. To make matters worse, the dealership did not provide a loaner vehicle. I had to go through the Uber driver's insurance, which only covered a compact car--completely impractical since I rely on a truck for work. This created a major inconvenience for me both personally and professionally. Communication was also very poor. I made multiple attempts to reach the service manager and was never able to get a response. The entire repair process took about 8 weeks, and during that time, I felt completely unsupported. What's most frustrating is that the dealership didn't offer anything to make up for the situation, despite the fact that this happened while my vehicle was in their possession. As a loyal customer who has purchased three vehicles from Simpson, I expected a lot more care and accountability. Overall, I'm very disappointed by the lack of compassion and customer service. I would have liked to feel like a valued customer, but unfortunately, that was not the case. Went from a clean carfax to a having a accident thank you Simpson

Comment : The truck I bought has been in service department more than any other vehicle I have owned that is under warranty. They usually have it 1 to 2 weeks each time and 2 times for the same antifreeze leak that they could not find. I had to take it to another dealer that had the truck 2 days and changed the radiator that was leaking. I now have it there for check engine light but it's been 6 days and they still haven't diagnosed it and Jose, the person in charge of my truck won't even return my calls. I have never seen such a lack of knowledge service department in my life. Stay away!!!!

Comment : We took our 2020 GMC Acadia to Simpson GMC for a major service. JJ helped us understand what was going on with our vehicle and kept us informed throughout the entire process. He was able to explain everything to us from beginning to end. I appreciate his knowledge and expertise. I will continue request JJ when I bring my vehicle to get serviced.
