Recalls (1)

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:CONTROL UNIT/MODULE04/09/2020

Hyundai Motor America (Hyundai) recalled certain 2019-2021 Tucson vehicles on September 4, 2020. On December 30, 2020, Hyundai expanded the recall population, and added certain 2016-2018 Tucson vehicles. The Anti-lock Brake Hydraulic Electronic Control Unit (HECU) could corrode internally and cause an electrical short, possibly resulting in an engine compartment fire.

Risk: An engine compartment fire can increase the risk of injury or crash.

Fix: Hyundai will notify owners, and dealers will replace the HECU fuse. For 2019-2021 model years, the Electronic Stability Control (ESC) software will also be updated. Recall repairs will be performed free of charge. Owners are advised to park outside and away from structures as a precaution until the recall repair is complete. The recall began November 2, 2020. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 195.

High theft risk

#17 most stolen in 2025

The Hyundai TUCSON was the #17 most-stolen vehicle in the United States in 2025, with approximately 5,900 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.
