First service on this truck at Mark Christopher. Was hesitant to take it because the past few services performed on my 2019 GMC were subpar. I had spark plugs and waited changed and when I got my tr Was hesitant to take it because the past few services performed on my 2019 GMC were subpar. I had spark plugs and waited changed and when I got my truck back and did an inspection I noticed that the technician had brok n my engine compartment harness mount on driver side. Nothing was mentioned to me. On another visit I had my brakes done on my 2019 in which they never replaced the brake monitor sensor which should be done every time with the brakes. I also had the battery changed out on my 2019 GMC sierra and the tech left one of the battery bracket bolts on my engine cowl in which I found later. I'm expecting much more from dealership service than I have received in the past. This last visit though with my 2025 GMC sierra checked out ok. I went through everything and did my own inspection just to make sure everything was done right. I think a little more quality control on your guys end after a vehicle has been serviced may put my mind more at ease in taking my vehicles to the dealership for service. More

I will never use this dealership again, either to purchase a vehicle or to service any of my four Chevrolets. Negative experience starting with "Carlos" when I drove up and after a 2 hour wait for a purchase a vehicle or to service any of my four Chevrolets. Negative experience starting with "Carlos" when I drove up and after a 2 hour wait for an oil change that was scheduled and ended with the service advisor Jacqueline Klosky not applying my Chevrolet rewards points as requested.

Service was great. Had a 1 pm appt, but took car in early and they finished work two hours later. Did not give full stars because it took them 40 min to check me in.

I am extremely disappointed that I’ve had to bring my truck in three separate times for the same radio issue. I was informed that the radio had been replaced with a brand-new unit, yet the problem has pe truck in three separate times for the same radio issue. I was informed that the radio had been replaced with a brand-new unit, yet the problem has persisted. I just picked up the vehicle last week, and the issue has already started again today. This is a brand-new 2025 model, and it should not be experiencing any problems of this nature. I would appreciate a prompt resolution to this matter. More
