Federal regulators said a software problem could cause some vehicles to brake unexpectedly, increasing the risk of rear-end crashes.
WASHINGTON — Hyundai is recalling more than 421,000 vehicles in the U.S. because a software issue could cause the automatic emergency braking system to unexpectedly activate.
The recall affects certain 2025 and 2026 model year Hyundai Tucson, Hyundai Tucson Hybrid, Hyundai Tucson Plug-In Hybrid and Hyundai Santa Cruz vehicles.
According to the National Highway Traffic Safety Administration, software in the vehicles’ front cameras may cause the forward collision avoidance system to be overly sensitive in some driving situations, potentially triggering sudden braking earlier than drivers expect.
Federal regulators said the issue increases the risk of a rear-end crash from vehicles traveling behind the recalled models.
Hyundai said dealers will update the front camera software free of charge.
Owner notification letters are expected to be mailed July 17, according to the recall report. Vehicle identification numbers became searchable on NHTSA’s website on May 20.
The automaker said it received 376 reports related to the issue between October 2024 and April 2026. Four reports involved crashes in which Hyundai vehicles were rear-ended, resulting in four reported injuries. No deaths or fires linked to the issue have been confirmed.
A breakdown of the number of vehicles involved in the recall is estimated as follows:
- 292,805 Tucson vehicles
- 110,844 Tucson Hybrid vehicles
- 13,082 Santa Cruz vehicles
- 4,347 Tucson Plug-In Hybrid vehicles
