Federal regulators say a software problem could cause some vehicles to brake unexpectedly, increasing the risk of rear-end crashes.
Washington – Hyundai Motor remember More than 421,000 vehicles in the United States are affected by a software issue that could cause their automatic emergency braking systems to activate unexpectedly.
The recall affects certain model year 2025 and 2026 Hyundai Tucson, Hyundai Tucson Hybrid, Hyundai Tucson Plug-in Hybrid and Hyundai Santa Cruz vehicles.
Software in a vehicle’s front-facing camera may cause forward collision avoidance systems to be overly sensitive in certain driving situations, potentially triggering sudden braking earlier than a driver expects, according to the National Highway Traffic Safety Administration.
Federal regulators say the problem increases the risk of rear-end collisions for vehicles traveling behind recalled models.
Hyundai said dealers will update the front-facing camera software for free.
Owner notification letters are expected to be mailed out on July 17, according to the recall report. On May 20, VINs will be searchable on the NHTSA website.
The automaker said it received 376 reports related to the issue between October 2024 and April 2026. Four of the reports involved rear-end collisions involving Hyundais, resulting in four injuries. There have been no confirmed deaths or fires related to the issue.
The number of vehicles involved in the recall is estimated as follows:
- 292,805 Tucson vehicles
- 110,844 Tucson Hybrids
- 13,082 Santa Cruz vehicles
- 4,347 Tucson plug-in hybrid vehicles
