Signs Your Car Needs Some Care
Not sure if it’s a quick DIY fix or time for a mechanic? Book an inspection if you notice any of these:
- A check engine, brake or battery warning light
- Squealing, grinding, knocking or clunking noises
- Fluid spots under the car: oil, coolant or transmission fluid
- The car pulls, vibrates or the steering feels loose
- Rough shifting, hard starts or loss of power
- Warm air from the AC or a burning smell
- Worse fuel economy than usual

More ways we can help
Beyond the services above, our Kearns technicians handle the everyday work that keeps a vehicle reliable:
- Batteries, belts and hoses: tested and replaced before Utah’s cold mornings and hot summers find the weak spot.
- Fluid services: coolant, brake, power steering and differential fluid changed on your manufacturer’s schedule.
- Same-day work: oil changes, brake jobs, diagnostics and alignments are often done the same day. Call ahead to check availability.
How Often Should You Get Auto Maintenance?
Most vehicles benefit from routine maintenance every 5,000–7,500 miles, depending on your manufacturer and how you drive. Stop-and-go traffic on 5400 South, short trips, towing and Utah’s hot, dry summers and cold winters all count as hard use. Follow your owner’s manual, and use this as a guide for the most common services:
| Service | Typical interval |
|---|---|
| Oil change | 3,000–7,500 miles depending on oil type |
| Tire rotation | Every 5,000–8,000 miles |
| Brake inspection | Every 10,000–15,000 miles or once a year |
| Alignment check | Yearly and with new tires |
| Tune-up | Every 30,000 miles or three years |
| Transmission fluid | Every 30,000–60,000 miles |
| AC check | Every 1–2 years, before summer |
Stop by any time and we’ll put together a maintenance plan for your vehicle.

What Auto Repair Costs at Master AutoTech Kearns
We don’t guess at prices. We inspect first, explain what we find and give you an estimate before any work starts, so you approve the cost up front. The check engine light scan is free, and you can request an estimate online. What drives the price is the part that failed, the labor to reach it, your vehicle and the parts grade you choose. Routine maintenance is priced as packages, starting with ProCare oil service at $79.95.
Need to spread out the cost? Master AutoTech offers several financing options, including the Goodyear Credit Card (6-month special financing on purchases of $250 or more), the Synchrony Car Care credit card, the 1stMILE Mastercard, Snap Finance, Acima, Surepay and RC Willey financing.

Tania King
“Riley did awesome work to my 05 Saturn Relay had an exhaust leak. Took care of my vehicle in less than 30 min and got me back on the road. I’ll be sure to return, for any other future services. Thank you!”
Juan Araujo
“These guys know their stuff about trucks. I didn’t know Master Muffler did more than exhaust? I needed an oil change on my truck and stopped in to ask for the service. They do provide it with a reasonable price and a courtesy check on brakes visually to help customer stay safe on the road was no extra charge. Wow! I’ll be back. Thank you guys for the great service!”
