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 Twin Falls technicians handle the everyday work that keeps a vehicle reliable:
- Batteries, belts and hoses: tested and replaced before Idaho’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 Addison Avenue and Blue Lakes Boulevard, short trips, towing and Idaho’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.

“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
“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!”
