2021 Hyundai Santa Fe Complaint Log

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.

WHILE IN DRIVE AND STATIONARY, MY VEHICLE HAS CONTINUOUSLY CAD CONNECTIONS ISSUES WITH MY MOBILE PHONE. I HAVE RECEIVED THE SAME ERROR MESSAGE STATING 'PHONE NOT RESPONDING. PLEASE RECONNECT IT AND TRY AGAIN.' THIS HAS HAPPENED WHILE DRIVING THROUGH AREAS I'M UNFAMILIAR WITH AND PUT MYSELF AND OTHERS AT RISK WHILE TRYING TO REGAIN CONNECTION. I'VE LEFT MY VEHICLE AT THE DEALERSHIP, BUT WAS TOLD THE PROBLEM WAS MY CELLPHONE AND WAS ADVISED TO PURCHASE A NEW PHONE. WHEN I SPOKE TO THE WOMAN AT THE CORPORATE HYUNDAI NUMBER, SHE ADVISED ME THAT MY PHONE WAS VERY MUCH COMPATIBLE AND SHOULD NOT HAVE ANY CONNECTION PROBLEMS, WE TROUBLESHOOTED MANY TIME, BUT I STILL CONTINUE TO HAVE THIS ISSUE.
