Our technicians hold certifications that go well beyond what most dealerships offer:

• ASE Certifications (Automotive Service Excellence) — the industry's gold standard for technician competence
• GM World Class Technician Certification — the highest level of GM factory training available
• Toyota Certifications — factory-trained on Toyota vehicles
• Ford Certifications — factory-trained on Ford vehicles

That cross-brand expertise is why we can confidently service nearly any vehicle that comes through our doors — and back every repair with our guarantee.

Yes — all of our work is guaranteed. Every repair, every maintenance service, every diagnosis. If you have an issue with work we performed, bring it back and we'll make it right. That's a promise backed by three generations of the Kemna family name.

Three things set us apart: factory-trained technicians with ASE, GM World Class, Toyota, and Ford certifications; OEM diagnostic equipment that reads your vehicle's systems the way the manufacturer designed it to be read; and genuine GM parts backed by manufacturer warranties. Combine that with our guarantee on all work, and you get repairs done right the first time — not the cheapest option that leads to a return visit.

We service all makes and models. While we're a Buick and GMC dealer, our cross-brand certified technicians work on:

• Buick, GMC, Chevrolet, Cadillac (all GM brands)
• Ford, Lincoln, Mercury
• Toyota, Lexus, Scion
• Honda, Acura, Nissan, Infiniti
• Ram, Dodge, Chrysler, Jeep
• Hyundai, Kia, Mazda, Subaru, Volkswagen
• And nearly anything else that comes through our doors

All work is guaranteed regardless of brand.

No. We service vehicles regardless of where they were purchased — whether you bought it from us, another Kemna location, another dealership, a private seller, or out of state. All work is guaranteed.

Yes. We service diesel-powered vehicles including GM Duramax, Ford Power Stroke, Ram Cummins, and other diesel engines. Common diesel services we perform include diesel oil changes, fuel filter replacement, DEF (Diesel Exhaust Fluid) service, glow plug replacement, turbocharger diagnostics, EGR system service, regen issues, and emissions system repairs. All diesel work is guaranteed.

Yes. Our service department is equipped to handle medium-duty trucks including Chevrolet Silverado Medium Duty, GMC Sierra Medium Duty, Ford F-Series Super Duty, and Ram heavy-duty trucks. We service Class 3 through Class 7 trucks for routine maintenance, repairs, diagnostics, and emissions work. Call our Service Department at (515) 515-1429 to discuss your truck's specific needs and confirm we can handle the work.

Yes. We work with local businesses, farms, contractors, municipal fleets, and commercial operators throughout north-central Iowa.

Yes. We accept major fleet management company cards and programs including GM Business Choice, GM Fleet, ARI, Element, Enterprise Fleet Management, Wheels, LeasePlan, Donlen, and most commercial fleet card programs. Talk to your service advisor about your specific fleet program when you schedule.

Yes. We use OEM-grade diagnostic equipment to read fault codes, analyze live data, and pinpoint the actual root cause — not just the symptom. Whether it's a check engine light, ABS warning, traction control fault, airbag light, tire pressure warning, or any other dashboard alert, our certified technicians have the equipment and expertise to diagnose it correctly the first time. All diagnostic work is guaranteed.

We use manufacturer-grade diagnostic tools — GM's Global Diagnostic System (GDS2), Ford IDS, Toyota Techstream, and other OEM scan tools — not the generic code readers many independent shops rely on. That means we can perform module programming, key programming, software updates, sensor calibrations, and deep system diagnostics that generic tools simply can't access.

Yes. We perform engine control module (ECM) reprogramming, transmission control module (TCM) updates, body control module (BCM) programming, infotainment software updates, key fob programming, and other software services. Many manufacturer recalls and Technical Service Bulletins (TSBs) require module reprogramming, which we handle as part of our authorized dealer service.

Yes. As an authorized GM dealer, we service hybrid systems and electric vehicle (EV) drivetrains including the Hummer EV and other GM electrified models. Our technicians are trained on high-voltage safety procedures and have access to specialized EV diagnostic and repair equipment.

Yes. We sell and install all major tire brands at our Fort Dodge location, including Goodyear, Michelin, Bridgestone, Firestone, BFGoodrich, Continental, Pirelli, Cooper, Hankook, Kelly, General, and Uniroyal. Whether you need passenger tires, light truck tires, all-terrain, mud-terrain, performance, or winter tires, we'll find the right set for your vehicle and budget.

It's exactly what it sounds like: buy three eligible tires and get the fourth for $1, with installation included at Kemna Buick GMC of Fort Dodge. This is a current GM Certified Service promotion on select tire brands. The fourth tire must be of equal or lesser value to the highest-priced tire in the set, and the maximum consumer purchase price is $450 per tire. Limit one offer per VIN. The promotion runs through May 31, 2026 — visit our Service & Parts Specials page or call (515) 515-1429 for current eligible brands.

Yes. Our tire price match guarantee works two ways:

• Before purchase: Show us a better eligible price from a competing tire retailer within 100 miles, and we'll match it.
• After purchase: Find a better price within 30 days of buying tires from us, and we'll refund the difference.

Eligible tire brands include BFGoodrich, Bridgestone, Continental, Cooper, Firestone, General, Goodyear, Hankook, Kelly, Michelin, Pirelli, and Uniroyal.

Beyond new tire sales, we offer tire rotation, balancing, computerized four-wheel alignment, flat repair, valve stem and TPMS sensor replacement, seasonal tire changeover (summer/winter swaps), tire storage, and tire pressure monitoring system (TPMS) reset and programming. Tire rotations are included with our oil change packages.

Most manufacturers recommend rotating tires every 5,000 to 7,500 miles — typically with every other oil change. Regular rotation extends tire life, improves handling, and is often required to keep your tire warranty valid. We include tire rotation with most oil change services.

Not at our Fort Dodge location directly. For express oil changes and routine quick service, we partner with Express Lube of Fort Dodge — a Valvoline Express Care location — to deliver fast, drive-through service for our customers. For factory-recommended GM Dexos full synthetic oil service, computer-monitored maintenance, and any work that requires factory diagnostic equipment, our certified service department is the right choice.

Current pricing on factory-recommended synthetic oil changes:

• 6-Quart ACDelco GM OE dexos®1 Full Synthetic Oil Change and Tire Rotation — $69.95 (most vehicles)
• 8-Quart ACDelco GM OE dexos®1 Full Synthetic Oil Change and Tire Rotation — $79.95 (larger engines)

Pricing excludes diesel engines and Corvettes. Tax and tire balancing extra. Diesel oil changes are priced separately based on capacity and oil specification. See current pricing on our Service & Parts Specials page.

Every service appointment includes a complimentary multi-point inspection of:

• Tire tread depth and pressure (all four tires)
• Brake pads, rotors, and brake fluid
• Battery condition and charging system
• Engine air filter and cabin air filter
• Wiper blades
• All fluid levels — coolant, transmission, power steering, brake, washer
• Belts and hoses
• Exterior lighting
• Suspension and steering components

You'll get a written report on every appointment so you can plan ahead instead of getting surprised.

An appointment-based oil change with multi-point inspection typically takes 45 minutes to an hour. Drop-off and pickup options are available, and we offer vehicle pickup and delivery if you can't bring it in yourself. Call (515) 515-1429 to schedule.

Full brake service including brake pad replacement, rotor replacement or resurfacing, brake caliper service, brake fluid flush, brake line repair, ABS system diagnostics and repair, parking brake adjustment, and complete brake system inspection. We use ACDelco Silver, ACDelco Gold, and GM Genuine Parts brake components with manufacturer-backed warranties.

Current front brake pad pricing (installed):

• ACDelco Silver front pads — $174.95 (12-month/unlimited mile warranty)
• ACDelco Gold front pads — $184.95 (24-month/unlimited mile warranty)
• GM Genuine Parts front pads — $199.00 (24-month/unlimited mile warranty)

Front rotor pricing starts at $279.95 (ACDelco Silver, most cars and small SUVs) and varies by vehicle. Rear brakes priced separately. Rebates of up to $60 per axle are currently available on select brake pads and rotors — see our specials page for current offers.

Common warning signs include: squealing or grinding noises when braking, longer stopping distances, a vibration or pulsation through the brake pedal, the brake warning light on your dash, a soft or spongy brake pedal, or pulling to one side when braking. If you notice any of these, bring it in for a free brake inspection — driving on worn brakes can damage rotors and is a safety risk.

Yes — free battery test and inspection. We test battery voltage and load, inspect terminals for corrosion, check cables for damage, inspect the battery case, and verify proper mounting. Stop by during service hours — no appointment needed for a quick battery test.

We stock and install ACDelco batteries with industry-leading warranties (installation included on most vehicles):

• ACDelco Silver 18-month — $129.98 (18-month free replacement)
• ACDelco Gold 30-month — $169.98 (30-month free replacement)
• ACDelco Gold 42-month — $199.98 (42-month free replacement)
• ACDelco Gold 36-month AGM — $257.98 (36-month free replacement, for vehicles requiring AGM batteries)

Most batteries can be installed same-day if we have your size in stock.

Most car batteries last 3 to 5 years depending on driving conditions, climate, and vehicle electrical load. Iowa winters and summers are both hard on batteries. Signs you need a new battery: slow engine cranking, dashboard battery light, dim headlights, electrical issues, or a swollen battery case. Get yours tested annually after year 3.

Complete factory-scheduled maintenance including:

• Oil and filter changes (conventional, synthetic blend, full synthetic, diesel)
• Tire rotation and balancing
• Multi-point inspections
• Air filter and cabin filter replacement
• Coolant flush and refill

• Brake fluid flush
• Power steering fluid service

Yes. Our Cooling System Refresh is $154.95 and includes radiator and pump inspection, hose and clamp inspection, belt inspection, and a complete coolant flush and refill with the correct factory-specified coolant. Critical for Iowa summers and winters.

Yes. Four-wheel computerized alignment is $89.95, front-end (two-wheel) alignment is $69.95. We check steering, suspension, shocks, tie-rods, ball joints, set toe-in, camber and caster (where applicable), and inspect tires for uneven wear. Recommended whenever you install new tires or notice pulling, uneven tire wear, or steering wheel vibration.

Yes. We perform engine diagnostics, repair, rebuild, and replacement — including head gasket repair, timing chain or belt replacement, cylinder head work, fuel injector service, turbo and supercharger repair, EGR system service, and complete engine swaps when needed. All engine work is guaranteed, and we use GM Genuine Parts or equivalent OEM components.

Yes. Currently a $200 rebate is available on the purchase and installation of select GM Genuine Parts engines, transmissions, and transfer cases. Limit one rebate per service per vehicle. See our Service & Parts Specials for current eligibility and rebate submission deadlines.

Yes. Engine misfires, knocking, ticking, rough idle, loss of power, and unusual noises all have specific diagnostic procedures. Our technicians use OEM scan tools, live data analysis, compression tests, and listening tools to identify the cause — whether it's spark plugs, fuel injectors, ignition coils, timing components, or something deeper. We diagnose first, quote second, repair third.

Yes. We perform complete transmission service including:

• Transmission fluid and filter changes
• Transmission flushes
• Transmission control module (TCM) programming and updates
• Shift solenoid replacement
• Torque converter service
• Transmission rebuilds
• Complete transmission replacement
• Transfer case service and replacement (4WD/AWD)
• CVT, automatic, manual, and dual-clutch transmission service

All transmission work is guaranteed. The $200 GM Genuine Parts rebate applies to qualifying transmission replacements.

Warning signs include: delayed engagement when shifting from Park to Drive, hard or jerky shifts, slipping (engine revs but vehicle doesn't accelerate), burning smell, transmission fluid leaks (red or brown fluid under the vehicle), unusual humming or grinding noises, or the check engine light. Don't ignore these — early diagnosis often means a much smaller repair bill.

Most manufacturers recommend automatic transmission fluid service every 30,000 to 60,000 miles, though some "lifetime" fluids extend to 100,000+ miles. Severe driving conditions (towing, heavy loads, stop-and-go traffic) require more frequent service. Check your owner's manual or ask a Kemna service advisor for the specific recommendation for your vehicle.

Yes. We come get your vehicle, service it at our Fort Dodge location, and return it to you.
