The lawsuit, which was filed with the US District Court in the Southern District of New York late Tuesday, alleges that Hyundai Motor America and Kia America Inc. failed to keep up with other automakers by not adopting immobilizer technology that ensured car ignitions could not be started without their keys. The New York City police department reports that about 287 Kias were stolen last year, compared with approximately 119 in 2021. Approximately 415 Hyundais were reported stolen in 2022, compared with 232 a year earlier. And the problem has continued, with an estimated 977 Hyundai and Kia vehicles reported stolen in the first four months of this year. There were only 148 such thefts in the same months last year. New York, the nation's biggest city by population, joins a growing list of cities going after the carmakers following a raft of thefts, including Baltimore, Cincinnati, Cleveland, Milwaukee, San Diego, and Seattle.
