From the Sierra to the Yukon, GMCs deserve a shop that knows their engines, drivetrains, and quirks. Our Warwick technicians service every GMC model with proper tools, factory-spec parts, and 17 years of hands-on experience — at a fraction of dealership pricing.
GMCs are everywhere on Rhode Island roads. Sierras pulling boats down to Oakland Beach. Yukons running family duty between East Greenwich and Cranston. Acadias commuting on I-95. Canyons working job sites across Kent County. Each one deserves a shop that knows the ins and outs of GMC engines and drivetrains — without the dealership wait or markup.
Primary Care Auto Repair has served Warwick and the rest of Kent County for 17 years. Owner Jeff Roy and our technicians work on every GMC lineup — Sierra 1500, 2500HD, 3500HD, Yukon, Yukon XL, Acadia, Terrain, Canyon, and Savana vans. Our team has seen the 5.3L AFM lifter failures, the 6.2L oil consumption, the Acadia timing chain issues, and the 6L80 transmission quirks — and learned exactly what it takes to fix them right the first time.
Every GMC repair includes a free video inspection sent straight to your phone. You see the worn part, the leaking gasket, or the failed sensor before any work is recommended. That kind of straight-up communication is why GMC owners from Apponaug, Conimicut, Hoxsie, Cowesett, and Oakland Beach trust our Warwick auto shop for everything from quick oil changes to major engine work.
The shop sits at 33 Locust Ave, just off Post Road, minutes from Warwick Mall, T.F. Green Airport, and the Route 2 corridor. Easy access from I-95 and Route 117 makes drop-off simple from anywhere in Kent County. Most GMC service jobs are completed same day, with bigger repairs quoted upfront and finished on a clear timeline.

Every GMC has its own pattern of issues. Knowing which ones are common — and which are urgent — saves you time and money. Here are the GMC problems we diagnose and fix most at our Warwick shop.
The Active Fuel Management lifters on the 5.3L V8 are a known weak point in Sierra 1500 and Yukon. We diagnose, replace, and disable AFM if you'd rather not deal with it again.
The 6.2L V8 in Sierra Denali and Yukon Denali burns oil between changes. We check piston ring condition, valve seals, and PCV system to find the cause and recommend the right fix.
Older 2.4L Ecotec engines in Terrain stretch timing chains, set codes, and lose power. The 3.6L V6 in older Acadia also has timing chain wear. We replace with the engine still in place.
Hard shifts, slipping, or shudder on Sierra and Yukon transmissions are often valve body or torque converter related. We diagnose first, repair second — no guesswork.
Sierra HD and Savana diesel trucks need specialized service. Fuel system, injectors, EGR, and DEF problems all need proper diagnostics. We handle all of it in-shop.
Many GMC V6 and V8 engines develop intake gasket leaks over time, especially after winters of road salt in Warwick. We catch coolant leaks before engine damage.
From routine maintenance to major repairs, our technicians handle every GMC model and every GMC engine — V8, V6, EcoTec, turbo 4-cylinder, and Duramax diesel.
