TLC provided excellent service for my GMC Denali, including a front lift, new tires, and an oil change. Jack communicated all the details beforehand and kindly offered a loaner car during the service.

Yes, we service Sierra 1500, 2500HD, 3500HD, Canyon, Savana, Yukon, and other GMC models. Our team handles engine, suspension, brakes, electrical, and inspection-related repairs to spec. Fleet customers can set unit-by-unit plans matched to duty cycles.
Frequent issues include DEF quality faults, DPF clogging, Duramax turbo concerns, transmission slipping, and electrical sensor failures. Air-brake leaks and wiring corrosion are also common on high-duty cycles. Timely diagnostics and maintenance prevent breakdowns and higher repair costs.
Pricing depends on which components are worn and the labor time for your model. We inspect first, then provide a firm, written estimate so you know the total before work begins. To lock a diagnostic slot, book an appointment.
This warning usually points to a DPF restriction, contaminated or low DEF fluid, or a failed exhaust sensor. If ignored, the truck may enter reduced-power or limp mode to protect the engine. A scan confirms the fault and guides the correct repair.
Repairs include a 24-month or 24k-mile warranty on parts and labor. Your estimate and invoice list the exact warranty terms for each job. If you have a question about a specific component, we will confirm coverage before work begins.
