Karius Automotive offers the same state of the art tools the dealership has to diagnose why your car or truck isn't running right. Our computerized diagnostic tools give us a look into your car to see if your performance issue or check engine light is because of a missing/loose gas cap or a bigger internal engine issue. We never charge customers to diagnose their issue!

Squealing brakes are unsafe and embarrassing.

Make sure your car has the stopping power needed to keep your family safe with an inspection of your pads and rotors, master cylinder, brake hoses, calipers, hardware and fluid.

In some cases it is necessary to replace or resurface rotors. We are dedicated to providing customers honest answers and getting them back on the road with money in their pocket. We will never up-sell a product just to make a dollar.  

Routine Oil changes are one of the easiest maintenance items to ensure your car will be running for years to come. In addition, to an oil and filter change, we check coolant levels, belts, hoses, tire pressure and wipers to keep your car running great.

Beat the summer heat with air conditioning service.

During our basic air conditioning service we inspect the a/c unit, check for any leaks, check belts, outlet temperature, and refrigerant pressure. Recharge refrigerant if needed.
