Recall Service Review
My recall service appointment on 9/7/23 was reschedule by Jason Jackson. The reason was the tech going to be out for my original appointment which was 9/8/23. Jason Jackson service consultant at Suburban took care of me very well, I also ask him can we do the works package for an oil change with tire rotation. He said sure we can fit that in with your recall. Jason customer service is always on point and over the top.

I had a big issue with my Buick enclave transmission, it is obviously a manufacturer issue, my car stayed for long while till the issue diagnosed and repaired, and I had to take it back again. I can?t deny that everyone in the dealership?s service department including service manager and my advisor did their best to make me happy, and actually I am! I got my car back finally and hope that the issue is solved forever and nothing else comes up, I am testing i for few days now. So thank you Serra Buick GMC Rochester.

We went to Feldman of highland to look for a use Traverse that would meet our our needs. Kirk in sales met us outside and asked if he could us, he did. Two days later he called us and told us about a beautiful Traverse 2022 that just came in as a lease turn in. That next day we signed papers for the Traverse. Kirk was very pleasant to do business with and very helpful and courteous to us. We would also like to give credit to the rest of the Feldman team for all there efforts. Sincerely Ione

Great service!
What a fun day we had with our salesman, Ron Zontini. He made the car-buying process easy. Despite the anxiety of purchasing a vehicle and the unfortunate demand during this pandemic, we got through it unscathed. It helped that we did our homework. Ron gave us all the right answers to our questions. We drove off the lot with a gently used Dodge Durango. We also traded a vehicle that we were happy to part with!
