On the 2021-2024 Hyundai Elantra, the Forward Collision-Avoidance Assist (FCA) and Blind-Spot Collision-Avoidance systems can trigger hard automatic emergency braking when no real obstacle is present. Owners report sudden, unprompted braking at 40-65 mph on open road, plus false activation when a vehicle passes closely from behind in an adjacent lane (with Blind Spot set to Active Assist). The abrupt deceleration can cause tire skid and create a rear-end collision hazard. NHTSA has logged dozens of FCA/AEB complaints across 2021-2024 Elantras.
Common Symptoms
Sudden hard braking with no obstacle ahead
Red FCA warning flashes on dash
Braking triggered by a car passing from behind in an adjacent lane
Tires skid from abrupt deceleration
Adaptive cruise braking for nonexistent threats
Dealer cannot reproduce the fault
How to Fix
No full recall as of mid-2026; Hyundai addresses cases individually with radar/front-camera recalibration and FCA control-unit software updates via TSB. Sensitivity can be reduced or FCA temporarily disabled in settings, but it re-enables each key cycle. Document incidents and file an NHTSA complaint; persistent units may qualify under state lemon law. Calibration/software updates are typically warranty-covered.
