NHTSA complaint #11424621

Owner complaint summary

Message: I own a 2021 Hyundai Santa Fe with the Forward Collision-Avoidance Assist feature installed and activated. The Forward Collision-Avoidance Assist did not function properly to stop my car to avoid a low speed impact. I applied the brakes to stop. I could not avoid impacting another vehicle. The damage was minor. Hyundai did inspect my vehicle braking system on June 8 at Hyundai of Cool Springs. I was not provided full report on findings/corrective action. Hyundai America was supposed to provide a follow up report. I was called today and the Hyundai representative had no details on the brake inspection to share with me. I am suspicious. I think Hyundai is hiding a safety issue. I am reporting this event so the NTSB can contact Hyundai to determine if this is a safety defect needing corrective action.
