The Forward Collision Avoidance Assist (FCA) system is a crucial safety feature in Hyundai Tucson vehicles, designed to detect potential collisions and take preventive actions. When you encounter a "Check Forward Collision Avoidance Assist System" warning, it's important to understand the possible causes and solutions.

Common Causes

Several factors can trigger this warning:

  • Obstructed sensors
  • System malfunction
  • Recent collision or near-miss incident
  • Extreme weather conditions

Obstructed Sensors

The FCA system relies on a front radar sensor and a windshield-mounted camera. These can become blocked by:

  • Snow, ice, or frost on the windshield
  • Dirt or debris on the front grille
  • Heavy rain or fog

To resolve this, carefully clean the windshield and front grille area. Ensure the radar sensor cover (usually located in the lower front grille) is free from obstructions.

System Malfunction

Occasionally, the warning may indicate a genuine system malfunction. This could be due to:

  • Software glitches
  • Faulty sensors
  • Loose connections

If cleaning the sensors doesn't resolve the issue, it's best to have your vehicle inspected by an authorized Hyundai dealer.

Immediate Actions

When you see this warning:

1. Safely pull over and turn off the engine

2. Restart the vehicle after a few minutes

3. Check if the warning persists

If the warning disappears after restarting, it may have been a temporary glitch. However, if it continues, further action is needed.

Long-term Solutions

To prevent recurring issues:

  • Regularly clean your vehicle's sensors and cameras
  • Avoid aftermarket accessories that might interfere with sensors
  • Keep your vehicle's software up-to-date
  • Schedule regular maintenance checks

When to Seek Professional Help

Contact your Hyundai dealer if:

  • The warning persists after cleaning and restarting
  • You notice reduced effectiveness of the FCA system
  • There are other warning lights or unusual behavior

Remember, the FCA system is a critical safety feature. Ignoring warnings could compromise your vehicle's ability to prevent collisions.
