Hyundai says it's committed to ensuring the quality and integrity of its products. "A subset of Hyundai vehicles on the road in the U.S. today – primarily "base trim" or entry-level models – are not equipped with push-button ignitions and immobilizing anti-theft devices. It is important to clarify that an engine immobilizer is an anti-theft device and these vehicles are fully compliant with federal anti-theft requirements," the automaker said in a written statement. Hyundai made engine immobilizers standard on all of its vehicles made from November 2021 onward.
