GMC Auto Repair & Service
GMC truck and SUV service in Central Florida. Towing and heavy use handled honestly, ASE certified techs, inspection photos, 36 month nationwide warranty on repairs.
My GMC works for a living. Can an independent shop keep up?
GMC trucks around here earn their keep. Sierras pulling boats and trailers, Canyons running back roads, Yukons and Acadias hauling families and gear in the same week. Towing and Florida heat are hard on any vehicle, and they're hard in predictable ways. Transmissions, cooling systems, brakes and tires all work harder when there's weight behind you, and they wear on a shorter clock than a mileage chart assumes.
We're an independent shop, not a dealership, and our ASE certified technicians service GMC trucks and SUVs every week. If you tow, tell us how much and how often. That one detail changes what we watch and how often we suggest looking at it, and it's exactly the kind of thing a generic service interval can't account for.
Every job includes a digital inspection with photos sent to your phone, so you can see the brake measurement or the condition of the fluid yourself instead of taking our word for it. You approve the work before anything starts.
We handle factory scheduled maintenance and keep the records, so servicing your truck close to home doesn't put a factory warranty at risk. Our work carries a 36 month, 36,000 mile nationwide warranty, which is worth something when the truck spends its days away from the shop. Six locations: Haines City, Winter Haven, Lake Wales, Frostproof, Sebring and Wauchula.

Service planned around how you use the truck
Tell us you tow and the recommendations change. Weight behind the vehicle affects fluids, brakes and cooling long before the odometer says it should.

Our 36 month, 36,000 mile coverage is nationwide, so a repair holds up whether you're on a job site two counties over or a state away.

Took my GMC 3500HD in for front end service. They took the time to deal with my extended warranty company, difficult to do at best, and worked thru those issues. Work was completed promptly after approval was received. Johnny’s will be my service shop for any future issues.
