Hyundai is recalling more than 421,000 vehicles over a software issue that could cause the brakes to unexpectedly activate, increasing the risk of a crash.

The recall covers certain Hyundai Santa Cruz, Tucson, Tucson hybrid, and Tucson plug-in hybrid vehicles. The model years are 2025 to 2026.

According to the National Highway Traffic Safety Administration, software in the front cameras may cause the forward collision avoidance system to activate prematurely and unexpectedly apply the brakes.

There have been reports of four crashes as a result of the issue. Four people were reportedly injured in those crashes.

Owners will be notified by mail in mid-July. Owners can take their vehicle to a Hyundai dealership for a free software update.

The car manufacturer has had several recalls in recent months. In April, Hyundai recalled 290,000 vehicles for a defect that could cause seatbelt anchors to fail. In March, Hyundai announced it would stop selling 2026 Hyundai Palisade Limited and Calligraphy trims after a child’s death involving power seats that may not detect people or objects.
