MARIAYA provided information in a precise, yet comprehensive manner. She kept us informed during the week long repair process of our car. She passed on our information to a coworker to help us when she was not available. She was friendly and courteous, a pleasure to work with.

I never received a digital or physical copy of my inspection report, even after asking my service advisor for one. He stated it would be emailed to me but never was. I inquired about a windshield replacement but was not given a quote for parts or labor. Working in an automotive service department myself, I had hoped for a better experience with Dutton as my experience on the sales side was excellent.

Worst dealership service experience I've had.
I brought my GMC Sierra Elevation (2.7L, approximately 56,000 miles) in because it was sputtering and running poorly. After researching the issue, I found that this engine has known problems related to carbon buildup and fuel system concerns. I called the dealership, explained the symptoms, and was told to bring it in.
Because the truck was undrivable, I paid nearly $300 to have it towed about 60 miles to the dealership. After that, communication became a major problem. It took over a week just to receive an initial diagnosis, and throughout the entire process nobody offered a rental vehicle, discussed possible warranty coverage in detail, or provided meaningful updates unless I repeatedly followed up myself.
I purchased extended coverage on the vehicle and specifically asked whether the repair might be covered. Instead of helping me explore my options, I was immediately told it likely would not be covered. The dealership recommended cleaning the fuel system first before pursuing more extensive engine work that they estimated could cost thousands of dollars.
The entire repair process took roughly three weeks. In the end, I paid over $3,000 for the fuel tank to be removed and cleaned. When I picked up the truck, it was returned with virtually no fuel in it.
What frustrated me most was how the dealership handled communication and authorization. During the repair process, I asked my service advisor, Julio, whether the dealership could provide a complimentary oil change due to the lengthy delays. He told me he would look into it. Later, when I followed up by text message, he responded that the oil change had been completed. Since our only discussion was about a complimentary oil change, I reasonably assumed it had been approved.
When I arrived to pick up my truck, I discovered I was being charged for the oil change. I never authorized a paid oil change. I showed the text messages to management, but instead of acknowledging the misunderstanding, they were dismissive and argumentative. Julio was not present, and the manager refused to consider the documented conversation.
The dealership also replaced a gas cap after damaging it during service. Fortunately, I was not charged for that repair, but it raises additional concerns about performing work that was never discussed with me beforehand.
My biggest issue is not just the repair bill. It's the lack of communication, the delays, the failure to clearly explain warranty options, the unauthorized charges, and the unwillingness of management to take responsibility when presented with evidence of a mistake.
Based on this experience, I have no plans to return for future service, and I certainly will not be purchasing another vehicle from this dealership unless significant efforts are made to address these concerns.
