SummaryHyundai has settled a class action lawsuit that alleges that certain Hyundai and Kia Class Vehicles (defined below) contain defective ZF-TRW airbag control units (“ZF-TRW ACUs”) that are vulnerable to a condition called electrical overstress, which may cause the vehicles’ airbags and other safety features to fail during a collision. Hyundai has not been found liable for any claims alleged in the lawsuit. Instead, Hyundai reached a voluntary settlement (referred as “the Settlement” or “the proposed Settlement”) to avoid lengthy litigation and provide relief to people who own ed or leased Class Vehicles in the United States and U.S. Territories. Class Members may be entitled to compensation if they submit valid and timely Claims.

SummaryIn response to this trend, we engineered a software upgrade that addresses the social media theft method and made it available to owners of eligible models free of charge at authorized Hyundai dealers since early 2023. In addition to the anti-theft software, we’ve developed a new zinc-reinforced ignition cylinder protector hardware upgrade that can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because your Hyundai vehicle with the VIN listed above (“Subject Vehicle”) was not factory-equipped with an engine immobilizer and was previously eligible for the software upgrade, you are now eligible until March 31, 2027 to have the ignition cylinder protector installed — if you request it — at no cost to you through an authorized Hyundai dealership.
