Hyundai is adding about 471,000 SUVs to a September U. S. recall for an electrical short in a computer that could cause fires. And the company is warning owners to park the SUVs outdoors until they are repaired. The latest recall covers certain model-year 2016 through 2018, and additional 2020 through 2021, Hyundai Tucson SUVs. The vehicles have antilock brake system computers that can malfunction internally and cause an electrical short. That can lead to a fire.
