Anti-Theft Software Upgrade

In response to increasing threats targeting Hyundai vehicles without push-button ignitions and immobilizing anti-threat devices, we are introducing a free anti-theft software upgrade for all affected customers.  

Service Campaign Rollout Schedule

The anti-theft software upgrade will be launched as a service campaign for a total of almost 4 million vehicles, beginning on February 14 with more than 1 million model year 2017-2020 Elantra, 2015-2019 Sonata and 2020-2021 Venue vehicles.

The software upgrade is scheduled to be available for the remaining eligible affected vehicles by June 2023.


How Does it Work?

The software upgrade modifies certain vehicle control modules on Hyundai vehicles equipped with standard "turn-to-key-start" ignition systems. As a result, locking the doors with they key fob will set the factory alarm and activate an "ignition kill" feature so the vehicles cannot be started when subjected to the popularized theft mode. Hyundai owners must use then use their key fob to unlock their vehicles to deactivate the "ignition kill" feature.
