A new noise coming from your vehicle is never something to ignore—especially when it shows up while you’re driving. One of the most common complaints we hear at Delta V EuroWerks is, “My car is making a humming noise. What does it mean?” The truth is, a humming sound can come from several different components, and understanding the cause can help prevent bigger (and more expensive) problems down the road.
1. Tire Issues Are the Most Common Cause
If your car hums as speed increases, the first place to look is your tires. Uneven tire wear, low tire pressure, or old, cupped tires can all cause a rhythmic humming noise. Winter weather in Richmond can also cause pressures to drop quickly, making the sound more noticeable.
What to do:
Check tire pressure, inspect tread, and make sure your tires are wearing evenly. A rotation or replacement may eliminate the noise entirely.
2. Wheel Bearings May Be Wearing Out
Worn wheel bearings often create a deep humming or growling noise that gets louder as you accelerate. This is a serious issue because a failing wheel bearing can affect handling and even cause the wheel to seize if left unaddressed.
What to do:
Schedule a diagnostic as soon as possible. Our technicians can pinpoint which bearing is failing and replace it before it becomes a safety risk.
3. Transmission or Drivetrain Concerns
European vehicles—especially all-wheel-drive models—can develop humming noises when drivetrain components start to wear. Differential issues or low transmission fluid may cause a steady hum or whine while driving.
What to do:
Have the fluid levels checked and inspected for signs of wear. Early detection prevents major repairs later.
4. Engine-Related Noises
Sometimes the hum isn’t coming from the wheels at all. A failing serpentine belt, worn pulleys, or even a vacuum leak can create humming-like sounds under the hood.
What to do:
A full under-hood inspection can determine whether the noise is engine related.
