Electrical System,forward Collision Avoidance - filed 2026-11-02
My 2020 Hyundai Sonata has a recurring electronic system malfunction that causes multiple dashboard warning lights to illuminate, including the Forward Collision-Avoidance Assist System warning. When this occurs, the vehicle can suddenly lose the ability to accelerate. Most recently, this happened while driving in rain...

Complaints are reports filed by owners with the National Highway Traffic Safety Administration.

Crash ratings are NHTSA's own 5-Star Safety Ratings results.
