You get up late in the morning and are rushing to get out of your home. Your kids get inside the car, and you are ready to start your day when you hear something. You can hear a loud noise from under your car’s hood.


Automobiles have thousands of moving parts, and your vehicle is no exception. It will emit a strange noise at some point or the other. It is vital to understand that your car needs immediate attention to eliminate chances of further damage as well as making sure there is not a threat to the safety of you and your family on board. Checking the dashboard to confirm if any warning lights are on is the first thing you should do when you hear your car making an unusual sound.


Your certified mechanic at Hillmuth Certified Automotive will find it easier to get to the root of the problem if you provide him with detailed information when you talk with them. Try to remember what you were doing when the noise started. For example, you may need new brake pads if your car start squealing when you apply the brakes.


How Long Do Brakes Last

Contact Hillmuth Certified Automotive immediately if your vehicle is making an unusual sound and let one of our professional mechanics diagnose and fix it today!

Reliable Transmission Work at Hillmuth Certified Automotive


Hillmuth Certified Automotive works on any vehicle with automatic or manual transmissions for repair and replacement. Our four locations are conveniently located in Clarksville, Columbia, Glenwood or Gaithersburg, Maryland. Each location provides customers with the same high-quality parts and labor along with unparalleled customer service from experienced ASE-certified mechanics.


Transmission problems can run the gamut from minor problems to major overhauls.  No matter what, you shouldn’t wait to have them diagnosed. The transmission is an essential part of your vehicle as it transfers engine torque to the wheels. When it fails to shift into a higher gear as you accelerate, it can put you in danger, especially when merging into traffic.    Whatever your issue is with your manual or automatic transmission, Hillmuth Certified Automatic is here to provide you with the best repairs.
