KJB is the only auto shop who are willing to help you fix your broken vehicle on the big holiday as well. My vehicle broke down near by on thanksgiving around 7pm and everything seems closed then I towed my vehicle near truck stop then on that weekend on Saturday it was already start snowing but still start calling several dealers but they are the only one bring it in. It’s a family business and whole family start working on my vehicle outside the garage on heavy snow, someone driving to get parts and someone taking care of my vehicle on cold, heavily snowing period. After 4 hours of work, they said vehicle is ready to drive. During parking time they said they could’ve fix my vehicle on the same night as well if it was an emergency. Somehow towed company driver told me no of the dealers are open so I had to wait 2 days to figure out. If your vehicle ever get broke down near KJB highway 94 then don’t think of second just call them and your vehicle will be ready in couple hours. Thanks once again KJB. You guys are the best.

Went in for a heater core replacement on my 2019 Ram. Mike did a great job on it and had me back on the road in no time. Mike and Melissa were great to deal with and I am very satisfied with the service.

Best shop experience I’ve had very kind people and service they got my vehicle done fast and at a reasonable and great price they don’t sell you stuff you don’t need and if they run into a problem they call you and explain it and ask what you would like to do as where some shops just go and do it and add it to your bill they ask and give you great prices I will definitely be taking my business here from now on. Very stand up and honest people we need more shops and people like them

My wife and I were driving back from Minnesota on a very frigid winter Saturday night, when my wheel bearing died, 200 miles from home. KJB Auto Repair was a godsend. They were the only shop open on a Sunday morning. Mike and Melissa did an absolutely fantastic job getting the part and getting it installed. From the time the tow truck dropped off the car, we were back on the road in less than 2 hours.

My transmission went out while traveling to Minnesota. I found KJB thankfully on the way. Melissa and Mike are very professional and insightful and did a fantastic job being honest about the repair process. I definitely recommend them whether local or passing through town

We service most makes and models of domestic and foreign vehicles, including cars, trucks, and SUVs. If you have a specialty or vintage vehicle, feel free to contact us to confirm.

Do I need an appointment for service?

Appointments are recommended to ensure timely service, but we do accept walk-ins when availability allows. You can schedule an appointment online or by calling us directly.

How long will my repair take?

Repair times vary depending on the issue. Minor services like oil changes or brake pad replacements can often be completed the same day. For more complex repairs, we’ll provide an estimated timeline after diagnosis.
