Twin Falls’ Auto Repair Experts

When your vehicle hits a snag, you need a mechanic who understands the specific demands that come with living in Twin Falls. You need someone who has experienced the stop-and-go traffic on Blue Lakes Blvd to the heavy-duty hauling required for local agriculture and recreation.

We’ve transitioned from our roots as Master Muffler into a comprehensive “AutoTech” center. This means we’ve paired our exhaust expertise with high-level engine diagnostics, suspension work, and specialized diesel services. As a family-owned shop, we prioritize people over profits, ensuring you get honest advice and a 12-month/12,000-mile warranty that actually means something.

Comprehensive Maintenance & Mechanical Repairs

Our Twin Falls technicians handle everything from modern EVs to high-mileage work trucks.

Muffler & Exhaust

Our Twin Falls mechanics are the region’s specialists in both standard repairs and custom exhaust upgrades. Whether you’re looking for a quieter commute or a high-performance system to handle Idaho’s backroads, we provide durable solutions tailored to your vehicle.

Catalytic Converters icon

Catalytic Converter

Protect the Idaho air and your engine’s performance. A failing catalytic converter can lead to failed inspections and poor gas mileage; our team provides expert diagnostics and replacements to keep your emissions clean and your fuel efficiency high.

Brakes icon

Brakes

In a town with steep canyon grades and busy intersections like Blue Lakes Blvd, you need brakes you can trust. Our mechanics perform meticulous inspections of pads, rotors, and lines to ensure your vehicle has reliable stopping power in any weather.

Air Conditioning icon

A/C

Don’t let the high-desert heat make your summer drive miserable. Our technicians offer comprehensive A/C recharges and leak detection to ensure your vents stay ice-cold even during the hottest Twin Falls afternoons.

Electric Vehicle Repair

Hybrid & EV Repair

Modern Idaho drivers are switching to electric, and we are ready to help. We offer specialized maintenance for hybrid and electric vehicles, handled by mechanics who are specifically trained in high-voltage systems and specialized EV drivetrains.

Diagnostics icon

Engine Diagnostics

When that dashboard light flickers on, don’t guess—get answers. We use advanced diagnostic software to pinpoint the exact issue, helping our Twin Falls customers avoid unnecessary parts-swapping and getting to the root of the problem fast.

Tune Ups

A well-maintained engine lasts longer and runs better. Our routine tune-ups include checking spark plugs, filters, and ignition timing to keep your car idling smoothly and responding perfectly when you hit the gas.

Engine Repair icon

Engine Repair

From minor head gasket leaks to complete engine overhauls, we handle the “heavy lifting” of auto repair. Our Twin Falls team services all makes and models, providing high-quality mechanical work that keeps your car on the road for years to come.

Alignments icon

Alignments

Twin Falls roads can be tough on your suspension. If your car is pulling to one side, our precision alignment service will straighten your ride, improve your handling, and prevent your tires from wearing out prematurely.

Tires icon

Tires

Your tires are the only thing touching the road; make sure they’re in top shape. We provide expert mounting, balancing, and rotations to ensure you have the best possible traction for Idaho’s snowy winters and hot summers.

Shocks and Struts icon

Shocks & Struts

If your vehicle feels bouncy or “loose” while driving, it’s likely time for suspension service. We replace worn shocks and struts to restore your vehicle’s stability and comfort, especially when navigating uneven terrain or rural roads.

Transmission Services

Transmissions

Avoid the high cost of a total transmission failure with regular maintenance. Whether you drive an automatic or a manual, our mechanics provide the fluid flushes and repairs needed to keep your gears shifting seamlessly.

Oil Changes icon

Protect your engine from the dust and temperature extremes found throughout Twin Falls. Our oil changes include a premium filter and a multi-point safety inspection to ensure your vehicle is healthy between major service intervals.

Diesel Services

Diesel

Our Twin Falls mechanics understand the unique complexities of diesel engines. From heavy-duty work trucks to passenger diesels, we provide specialized fuel system, turbo, and glow plug services to keep your powerhouse running strong.

Our Tahoe had a check engine on and was surging and cutting out.  These professional guys got us in and did a wonderful job.  Super nice guys and very reasonable in their repair pricing.  Totally friendly and professional.  When I’m in town again and need repair for my truck or car, it’ll be Addison Car Care, who will fix my car.  I can trust them, and they are honest!

~ Daniel Gromer

Cole and Cody once again took care of me. Great communication and got me right in even though they’re busy. If I could give this shop more than 5 stars I would. Thanks fellas for taking good of my son’s truck. Let’s not forget to thank the techs. Great job!

~ Genaro & Tammy Acosta

I had an issue with my van. Everywhere else couldn’t get me in for about a week and the dealer couldn’t for a month! They got me in, in less than a day! They fixed the issue and they also called and updated and informed about each step they took. They were kind and professional!

~ Bailey Hoskins

The best in Twin Falls! I wouldn’t take my car anywhere else and always get minor tune ups done regularly with these guys. Excellent shop!

~ George Tucker
