What Is Undercarriage Damage?

The undercarriage is the bottom section of your car that houses critical components like the axles, brake lines, exhaust system, and suspension. Damage occurs when these parts are impacted by road debris, potholes, or curbs—or deteriorate over time.

How Can You Tell If the Undercarriage Is Damaged?

Look for these signs after hitting a pothole, curb, or debris:

  • Steering issues: Car veers to one side or becomes harder to control
  • Delayed turning: Poor response when turning, often due to a damaged steering knuckle
  • Fluid leaks: Oil, transmission fluid, or coolant puddles under the car
  • Scraping sounds: Vehicle bottoming out or making grinding noises
  • Vibrations: Shaking while driving, especially after an impact

Can You Drive a Car With Undercarriage Damage?

Technically yes, but it’s risky. Damage to control arms, suspension, or fluid lines can worsen over time and create safety hazards. If you notice any symptoms, it’s best to pull over, inspect the vehicle, and schedule repairs immediately.

How to Check for Undercarriage Damage

Follow this five-step process after an impact:

  1. Pull Over Safely: Stop as soon as you can to limit further damage.
  2. Inspect the Undercarriage: Use a flashlight to examine the underside.
  3. Look for Damage: Check for cracks, dents, scrapes, leaks, or loose parts.
  4. Categorize the Problem: Cosmetic damage may be minor; leaks, cracks, or alignment issues require attention.
  5. Note Handling Changes: If your car vibrates or pulls to one side afterward, get a professional inspection.
