- Some vehicles lack a passive engine immobilizer, allowing the engine to be started with a USB cord, prompting a free anti-theft software update from Hyundai.
- Warning lights for lane keeping, blind spot, ABS, autohold, and forward collision systems turn on and will not reset, misleading drivers into thinking a crash is imminent.
