Car maker Hyundai has recalled nearly 36,500 cars sold in Australia over a dangerous software fault in their onboard computer.

The affected models are the NX4-series Tucsons built between 2025 and 2026, with the fault affecting the Forward Collision Avoidance System.

The car is among the top-selling in Australia, coming in at number 11 in 2025.

'Due to a software issue, the Forward Collision Avoidance system may continue to apply sudden/unexpected braking even though it is no longer necessary to avoid a collision or reduce impact,' Hyundai's recall notice states.

'Sudden or unexpected braking may increase the risk of an accident, which can result in injury or death to vehicle occupants or other road users.'

The May 29 notice added that all variations of the 2025 and 2026 NX4 Tucsons sold in Australia are affected, which is 36,496 cars.

The Korean car manufacturer was recently in the news for another serious fault.

Up to 68,500 Hyundai Palisade and Palisade Hybrids were recalled in March and April in the United States after a child died because of a defect in the power-folding seats.

The seats were supposed to detect when there was an obstruction, but did not work in that case.

'Hyundai urges owners to use caution when operating the second and third-row power seat functions and to ensure that no person or object, including children, is in the seat or seat-folding area before operating the power seat,' the company said.

An 'over-the-air' software update added a safety warning to the touchscreen and improved the obstruction detection. 

Car owners in Australia affected by the latest recall will be written to by Hyundai and asked to take their car to an authorised Hyundai dealer where a software update will be done.
