Frequently Asked Questions

  • Do I need an appointment for a diagnostic check, or do you accept walk-ins?

    At Sunnyside Automotive, we want to make your vehicle care as seamless and stress-free as possible. Because we provide same-day diagnostics, we always do our absolute best to accommodate walk-ins whenever a sudden vehicle issue arises. Unlike some auto repair shops in Idaho Falls, ID that require days of advance notice, our certified technicians understand that car trouble rarely happens at a convenient moment, which is why emergency service is available to get you taken care of when you need us most. 


    However, if your schedule is tight and you want to ensure the absolute fastest turnaround time, we highly recommend contacting us today to schedule your vehicle for service in advance. Whether you walk in during an emergency or schedule your visit ahead of time, our commitment to integrity and efficient care remains the same. We respect your busy schedule and work hard to provide rapid, dependable answers so you can make informed decisions about your vehicle's mechanical issues without unnecessary waiting.

  • You mention Nissan and GM credentials-do you only specialize in those brands?

    Not at all! While our team proudly brings specialized Nissan and GM credentials to the table, we handle comprehensive repairs for all foreign and domestic vehicles. These specific manufacturer credentials simply showcase our deep technical expertise and dedication to advanced industry standards. The truth is, the majority of our skilled mechanics also hold ASE certification, giving them the comprehensive training required to accurately diagnose and resolve mechanical issues on any make or model you drive.


    Our extensive industry experience ensures that whether you bring us a domestic truck, a foreign sedan, or a specialized performance vehicle, it will receive the same high level of certified expertise. Drivers look for auto repair shops in Idaho Falls, ID that they can trust with any family vehicle, and our versatile skillset allows us to be that all-in-one solution for the community, regardless of the emblem on your grille.

  • Can you help me handle the paperwork if my repair is going through insurance?

    Yes, we absolutely do. Dealing with the aftermath of vehicle damage can be incredibly stressful, and navigating the complex insurance claims process only adds to that burden. As one of the most reliable auto repair shops in Idaho Falls, ID, we have been a trusted name in the community since 1959, and we believe our job is to support our customers through every single step of their repair journey. 


    We actively help coordinate with insurance companies to greatly simplify the repair process for you. Our team works directly with the claims adjusters, providing them with the precise documentation and accurate estimates they require to move your claim forward. By managing these details on your behalf, we help reduce the back-and-forth communication and prevent unnecessary administrative delays. You can depend on Sunnyside Auto to advocate for proper, safe repairs and to make the entire insurance experience as smooth and straightforward as possible.

  • Are your "free estimates" really same-day, and is there any obligation?

    When we say we provide complimentary estimates, we mean it. Our free, same-day estimates are 100% transparent and come with absolutely no obligation down the road. We believe that honesty and competitive pricing are the cornerstones of building a business that the community trusts, which is why we never utilize high-pressure sales tactics or hidden fees.

We then present you with a clear, thorough, written breakdown of what it takes to resolve the issue. This allows you to see exactly what your vehicle needs before you spend a single dime. It is this dedication to straightforward pricing and upfront integrity that sets us apart from many other auto repair shops in Idaho Falls, ID.

  • Do you offer upholstery/interior repairs at the same location?

    Yes, we proudly offer these specialized services right here at our main facility. Many standard auto repair shops in Idaho Falls, ID only focus on basic under-the-hood mechanical fixes, forcing you to drive all over town to different specialty shops if your vehicle has a torn seat. At Sunnyside Automotive, we operate as a truly comprehensive automotive solutions provider.


    We efficiently restore vehicle interiors to their prime condition to maintain peak safety, structural integrity, and driving comfort throughout your travel experience.

  • Can I browse used cars for sale while my current vehicle is being serviced?

    Absolutely! We highly encourage our service customers to look around our lot while our technicians work on their vehicles. Sunnyside Automotive is unique compared to ordinary auto repair shops in Idaho Falls, ID because we are also recognized as the top-rated used car dealer in Idaho Falls, ID.
