2019 GMC Sierra 4WD Double Cab Standard Box Elevation

We were 40 miles from home and our pickup started vibrating and losing acceleration power. It was a Friday and I knew the nearest GM service was in Mora would be our only hope of getting any issues fixed before the weekend. We had 400 more miles to go over the next two days and I expected our chances for any service on a Friday would be very slim. When I stopped at the Mora Chevy Buick service department, I saw a row of six keys and service paperwork sitting on the counter. Therefore I was expecting a quick referral from the service advisor that I would need to schedule a service appointment when their time would permit. Instead I watched as the two service advisors worked up a plan to see if one of the technicians could break away for a quick look and diagnosis on my pickup while keeping their other service commitments on schedule. They explained that this approach would at least give me insight to whether if I could keep driving or if I would cause more problems or damage if I continued. I was so excited that the Mora team was even willing to just look under the hood. I told my wife the plan and she asked if we could bring in our dog inside the dealership and into the waiting room; our dog was already terrified of the new surroundings and unfamiliar territory. I asked the receptionist about bringing in our dog and she had one restriction--the dog had to be cute. Thankfully every dog is cute in her eyes and she asked if there was anything else she could do to help us we were waiting. Because it was nearly lunch time, she even gave us some menus to restaurants we could walk to. As my wife and I planned our alternative weekend plans--including canceling our planned road trip--we assumed the pickup would likely need to stay through until next week to be service. It wasn't long before our advisor came out for an update but instead told us they found the problem, fixed it, and we could be on our way. What? Fixed? Our advisor then took the time to explain the diagnostic approach they used to give me confidence that the issue was fully resolved. Although one of the engine error codes pointed to bad gas, they tested it and it was fine. They found a bad spark plug in cylinder #5 that was causing the vibration and when they moved the #5 spark plug to cylinder #3, that cylinder began to fail--a sure sign that the problem had followed the spark plug; therefore a new spark plug was the solve. I appreciated the "can-do" service by everyone at the Mora Chevy Buick dealership--who seemed to understand what it was like to be away from home, having engine trouble and only passing through Mora. I appreciated their care and urgency to get us back on the road quickly even while being extremely busy with their Friday workload and commitments they had made to other service customers. Thanks to the Mora Chevy Buick team--from reception to service--we were able to get back on the road and continue the longer miles yet to come. We hope to visit them again but under normal, less urgent circumstances.
