Recalls (9)

VISIBILITY:SUN/MOON ROOF ASSEMBLY11/10/2016

Hyundai Motor America (Hyundai) is recalling certain model year 2015-2016 Sonata Hybrid vehicles manufactured December 8, 2014, to August 18, 2015, and Hyundai Sonata vehicles manufactured May 28, 2014, to March 18, 2016, equipped with the panoramic sunroof option. Due to a bonding issue with the sunroof wind deflector, the sunroof panel on the affected vehicles may detach while driving.

Risk: If the sunroof detaches from the vehicle it could become a road hazard, increasing the risk of a crash.

Fix: Hyundai will notify owners, and dealers will repair the wind deflector anchor plate, free of charge. The recall began December 2016. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 152.

Very high theft risk

#3 most stolen in 2025

The Hyundai SONATA was the #3 most-stolen vehicle in the United States in 2025, with approximately 17,687 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.
