A diagnostic code indicates that a system detected a problem, but it does not explain why it occurred. We take the extra steps needed to uncover the actual cause through detailed electrical and system testing. From check engine lights to intermittent electrical issues, we perform a thorough evaluation. Our goal is to deliver the right repair based on reliable diagnosis. 
We help drivers stay safe with comprehensive brake service focused on transparency and accuracy. Every visit includes a detailed inspection of critical brake components, allowing us to assess wear, performance, and potential concerns. Digital inspection photos let you review exactly what we find before any work begins. Our goal is to deliver dependable repairs without unnecessary recommendations. 
Vehicle fluids naturally degrade over time, reducing their ability to protect critical components. We provide complete service for oil, transmission, coolant, brake, power steering, and drivetrain fluids. Our process restores proper performance by flushing and replacing fluids according to specification. This helps maintain reliability and reduces the risk of costly mechanical failures. 
We deliver diesel diagnostics that interpret warning lights as starting points rather than final answers. A fault code alone cannot explain the full condition of the system. Using diesel-specific diagnostic tools and live data testing, we evaluate real-time engine behavior to determine the true cause. Each result is verified before any repair direction is provided. 
Our approach to oil leak repair prioritizes accurate diagnosis over temporary fixes. Rather than simply cleaning the area and assuming the problem is resolved, we locate the true source of the leak. This prevents recurring issues and further engine damage. Oil leaks can lead to serious mechanical problems if ignored, including low oil levels and overheating risks. We complete repairs carefully to ensure lasting protection. 
Our service includes precision wheel alignment and suspension evaluation utilizing Hunter Engineering equipment. We address issues such as drifting, uneven tire wear, and unstable steering by performing detailed diagnostics. Local driving conditions in Boise can progressively knock alignment and suspension components out of specification. We deliver Hunter-generated before-and-after reports so customers can review all adjustments clearly. 
We deliver professional cooling and heating system care aimed at preventing overheating and supporting reliable engine performance. Idahos summer conditions can stress critical components where coolant leaks thermostat failures or worn water pumps may quickly lead to costly damage. Our technicians perform full system diagnosis and pressure testing to identify issues accurately before any repair recommendations are made. This ensures your engine stays within a safe operating temperature range throughout the year. We provide a 3-year/36,000-mile warranty and make it easy to schedule your drop-off. 
Factory-scheduled maintenance is performed according to manufacturer specifications to help keep your vehicle dependable and your warranty protected. We follow 30K, 60K, and 90K service intervals and conduct digital inspections with photos and notes. Our recommendations are transparent so you understand your vehicles condition and can address issues before they become costly failures promptly identified 
Gear oil condition and seal integrity are critical for differential and transfer case performance. We service these systems to ensure smooth power transfer from engine to wheels in AWD, 4WD, and RWD vehicles. When fluid degrades or contamination occurs, internal wear can progress quickly. We help identify early signs and inspect all related components during service.

The thermostat on my pickup went out on a recent trip to Boise between Christmas and New Year's Day. That's a tough time to need a mechanic in a pinch! But, Sager and Sons stepped up to the plate for me. They conducted a thorough analysis and made meaningful recommendations for repairs without being pushy. I give Sager and Sons two thumbs up and five stars for their thoroughness and expertise in repairing my beloved 2005 Ford F-250 Lariat. I was able to get back on the road in a timely fashion after Sager and Sons repaired my vehicle. Thank you!

Im in town visiting family , and the battery on my car died without warning. My sister brings her vehicles to Sager & Sons, and called them to see if they could replace my battery. They were able to get me in right then, replaced the battery, cleared the error codes, and didnt charge me a cent for the shop time. So awesome!!! I truly appreciate them taking care of me as though I was a regular customer. And Shyanne was so helpful and sweet, and made sure I had all the information I needed. Thank you so much!!!

I have a pickup truck that is over 20 years old that had a fairly tricky braking issue. Had it to two other shops, one of which completely misdiagnosed the problem, before I took it to Sager and Sons. They had it correctly diagnosed and back to me ahead of schedule even though they had to order parts. Kept me informed every step of the way. Good people all around.

I have been taking our vehicles to Sager and Sons for a few years now. They have always provided consistent, friendly and competitively priced service. My last visit this week, my car was there for less than 24 hours and they successfully diagnosed and repaired all of the issues! Thank you guys for another job well done!
