Forward Collision Avoidance (AEB) Malfunctions

The Automatic Emergency Braking (AEB) system has shown reliability concerns, including unintended braking and false detections. Recalls addressed software/hardware incompatibilities, but owners should remain vigilant for erratic behavior. Estimated repair cost: $500 - $1500+.

Some reports indicate premature wear of brake rotors, requiring replacement at relatively low mileage points. Estimated repair cost: $400 - $800.
