I write this not just out of frustration, but out of profound disillusionment with a brand I once trusted implicitly. My GMC—a little over one year old—arrived with defective brakes. When I raised the screeching noise, your service team dismissed it as “basically new,” then demanded I pay out-of-pocket for replacement. I refused, citing obvious manufacturing fault; they shrugged. No apology. No urgency. No sense that I belonged to the “GMC family” they advertise. Weeks later, the truck began shaking violently—then overheated. I topped off antifreeze myself and booked service immediately. Thursday morning drop-off: they found a “small hole” in a coolant line. Parts ordered. Friday: another leak discovered. More parts. Monday, then Tuesday. No loaner available—only a paltry forty-five-dollar daily rental cap, as if my time, my safety, my livelihood were negotiable. Meanwhile, they casually informed me the rotors were warped—because of the very defective brakes they refused to replace. “We’ll shave them,” they said, “but new pads are on you.” I declined. Why should I fund their failure? Monday passed in silence. I called at two-thirty—still “testing lines.” Tuesday morning, nine o’clock, I had to chase them down. “Oh, it’s ready,” they said—like I hadn’t been stranded, inconvenienced, ignored. No update. No courtesy call. No accountability. This is not service. This is negligence dressed in corporate indifference. I demand a full investigation—into the defective brakes, the cascading coolant failures, the refusal of warranty coverage, and the utter disregard for customer dignity. I expect reimbursement for rental costs, replacement of all defective components at no charge, and a direct apology from someone who actually understands what “GMC” once meant. If this is the standard, I will not hesitate to take my next vehicle elsewhere—and I will make sure every forum, every review site, every potential buyer knows why. Respectfully, but unequivocally,

Intake with Rachael was great and Connie was great when i picked up the truck on a Sunday. The recall and coolant leak was fixed however when i checked the truck's on screen maintenance too see about the filter and oil change was done, the oil life and oil filter was still at 60%+-. I was told that they "must have forgotten to reset that", which left me wondering if it was in fact done.

Although Lawrence, the sales person who helped me was terrific Service Manager was anything short of that. The trucks service engine light came on the day after the purchase along with a couple of other idiot lights. I spoke to Lawrence and he tried to walk me through what to do although for naught! I came by the dealership, so Lawrence could take a look at it, he couldn’t figure it out so he went back to the service manager to see if we could get his help. The service manager said to make an appointment! My immediate thought was are you kidding me? It’s a brand new vehicle that was just purchased and he’s telling me to make an appointment! I come from that world, I ran and owned a 12 V shop when I was much younger and if anybody came into my shop complaining immediately after I installed something in their vehicle, I would absolutely stop what I was doing and attend to it. I just took it as a slap in the face! You wanted to know my feelings and now you have it! Let’s see what you do with it Thank you, Bruce Zion

Not the friendliest service advisor. He tried to upsell me a thirty thousand mile service and then later called and said, I needed rear breaks, when I only have thirty two thousand miles on my truck. I read my owner's manual and am educated on what services my truck needs. The brakes feel fine and I did ask to see what they looked like and was told its already off the lift. I can deal with the slight attitude but not the upsell b*******. I may service the truck elsewhere in the future.

My truck was not serviced and I my appointment ( was at 8am and i showed up at 7:55) was canceled even though I was the first customer on site. l brought to the service desks attention the fact that a repair that was done six weeks ago had failed and needed to be looked at again. Also, was questioning a charge that was misrepresented to me at the time and did not get my approval.
