NHTSA Complaint #11712796 — 2019 HYUNDAI TUCSON

On three occasions while the vehicle was idling, the dashboard screens and interior lights went completely black, and the steering wheel jerked abruptly in my hands. This sudden electrical failure creates a serious safety concern, particularly if it were to occur while driving at higher speeds. The dealer has not been able to reproduce the problem. There were no warning lamps, messages or other symptoms prior to the failure. There were no warning lamps after the problem occurred. The vehicle has been inspected multiple times by a Hyundai dealership. On one occasion, the dealership retained the vehicle for approximately two months but reported no definitive findings despite error codes being present. On a later visit following another failure, no error codes were recorded. The dealership replaced the head/stereo unit and confirmed no active recalls, yet the issue continues. This problem first occurred while the vehicle was covered under an extended warranty, but due to its intermittent nature, it was not resolved before the warranty mileage threshold was exceeded. I have since found numerous similar complaints online from owners of the same model year describing electrical blackouts and steering-related concerns. A Hyundai service manager advised me to dispose of the vehicle, which further reinforces my concern that the defect may be known but unresolved. I believe this issue represents a potential safety defect and warrants documentation and review. Thank you for your attention to this matter.
