I was willing to drive 5 hours to this dealership but my business was not worth anything to this dealership. Would not do business with them.

This dealership is all about the money, not about taking care of the customer! I have to repeat this, Colonial GMC is only about the money! Colonial GMC has zero morals, zero professionalism, zero integrity, and if they cannot get GM or someone other than the dealership to cover the cost, well the customer will NOT be taken care of. I wonder if they treat their own mothers like this? They will agree you have issues with your vehicle and even say they are sorry, but at the end of the day they offer ZERO solutions. I brought my GMC Canyon Denali in for an oil change. This was the closest GMC dealer to my house. When I arrived, I showed the service adviser a few issues that needed to be addressed at a later date, dash trim panel was bent from the factory, back up camera was blurry, front camera displayed inoperative, radio had frozen up, Apple CarPlay wouldn’t work, the driver information center displayed Chevrolet, not GMC, and a few rattles. He looked up my account and said you have a GM Certified warranty, so you have until 48,000 miles to bring it back to get the issues fixed. He never said that the issues would not be covered or that they would not be covered by the Certified part of my warranty. Well, when it came time for the dealership to act on what the service adviser said, nothing but excuses. I have 2,000 miles until the warranty is up, but it might as well been expired. All this dealership is good at is lip service. They blamed GM for them not being able to fix my issues and even said that the quality recently was in question. I had pictures and video s showing the issues. Do you think they wanted me to email this to them, NO? The reason is they had no intention of fixing my truck. They did not even offer me another solution. I told them I do not expect something for nothing, but I would think you would want to work with me. NO, WRONG AGAIN! All I got was the typical excuse, “we could not duplicate the issue” and it doesn’t matter you have pictures or video. Really!?! There only recommendation is to call the number on the back of your owners manual. Save yourself time, go somewhere else for sales, service, and parts! How they sleep at night is beyond me!
