Very high theft risk

#5 most stolen in 2025

The Kia OPTIMA was the #5 most-stolen vehicle in the United States in 2025, with approximately 13,900 thefts reported to law enforcement.

Kia Boys / TikTok theft vulnerabilityModel years 2010-2021 Hyundai and Kia vehicles without engine immobilizers were widely targeted starting in 2022 after a viral TikTok exploit. If you own this vehicle, verify it has an ignition immobilizer or install a security upgrade. Hyundai and Kia both offered free software updates and steering-wheel-lock programs for affected models.

Recommended protection: engine immobilizer verification, steering wheel lock, GPS tracker, and comprehensive insurance coverage. Higher theft risk usually translates to higher comprehensive-coverage insurance premiums.
