At Gray's Automotive Service, we've spent our days under the hood keeping our neighbors on the road. Diagnostic, electrical, and general repair — done right the first time. All work guaranteed.
I'm proud to run Gray's Automotive Service right here in Carmel. We're a small, hands-on shop — no corporate run-around, no upsells you didn't ask for. When you bring your vehicle in, you talk straight to the people working on it.
Cars have changed a lot over the years, but doing right by folks hasn't. We've built this shop on three simple ideas: tell you the truth about what your vehicle needs, charge a fair price for the work, and stand behind every job that leaves the bay.
From a quick oil change to a check-engine-light mystery, we handle the everyday stuff and the head-scratchers. Here's a look at what we do most often.
Computer Diagnostics
Check engine light on? We hook up the scan tool, read the codes, and figure out what's actually causing the problem — not just what's tripping the sensor.
Electrical System Repair
Wiring, alternators, starters, batteries, lights, power windows — if it runs on electricity, we can chase it down and get it working again.
General Auto Repair
The everyday work that keeps your car running — belts, hoses, pulleys, sensors, gaskets and the rest. If something's off, bring it by and we'll take a look.
Oil Changes & Maintenance
Conventional, synthetic blend, or full synthetic — we'll change your oil, top off your fluids, and check the things that often get missed.
Brake Service & Repair
Squealing, grinding, soft pedal? Brakes are not the place to wait it out. We do pads, rotors, calipers, brake lines, and full system flushes.
Tire Rotation & Balancing
Even tire wear means longer-lasting tires and a smoother ride. We rotate, balance, and check pressures any time your vehicle's in the shop.
Engine Repair
From rough idles and misfires to timing components and full rebuilds, we'll diagnose what's wrong and walk you through your options.
Transmission Service
Slipping, hard shifting, leaks? We service automatic and manual transmissions — from fluid and filter changes to deeper repairs.
Cooling System & Radiator
Overheating is a fast way to ruin an engine. We pressure-test, flush, and repair radiators, water pumps, thermostats, and hoses.
Heating & A/C Repair
Indiana summers and winters don't go easy on a car. We recharge A/C systems, repair heaters, and find the leaks that keep you sweating or shivering.
Batteries, Starters & Alternators
Slow cranks, dim lights, dead batteries on a cold morning — we'll test the system and replace what actually needs replacing.
Suspension & Steering
Rough rides, pulling, clunks over bumps — we replace shocks, struts, control arms, tie rods, and ball joints to get your ride feeling right.
Belts & Hoses
A snapped serpentine belt or a leaky hose can leave you stranded. We inspect them on every service and replace before they fail.
Tune-Ups
Spark plugs, ignition coils, air filters, fuel filters — the routine stuff that keeps your engine running smooth and your fuel economy where it should be.
Pre-Purchase Inspections
Thinking about buying a used car? Bring it by before you sign anything. We'll look it over and tell you straight what we see.
Exhaust System
Loud rumble, rattle, or a smell of fumes? We repair and replace mufflers, catalytic converters, pipes, and exhaust manifolds.
Fuel System Service
Hard starts, hesitations, poor mileage? We service fuel pumps, injectors, and lines, and clean what needs cleaning.
Scheduled Maintenance
Got a 30K, 60K, or 90K service due? We follow your manufacturer's recommendations to keep your warranty intact and your car healthy.
