Hyundai Motor is grappling with two significant recalls in the U.S., pulling nearly half a million vehicles off the road due to risks of sudden braking and fire, highlighting growing software and hardware complexities in the automotive industry.

Hyundai Recalls Nearly 500,000 US Vehicles Over Two Separate Defects
(P1) Hyundai Motor Co. is recalling a combined 475,415 vehicles in the U.S. across two separate campaigns, addressing critical software and hardware defects that could lead to unexpected braking or fire. The recalls, confirmed by the National Highway Traffic Safety Administration (NHTSA), underscore the increasing operational risks automakers face from the complex electronic systems in modern cars.
(P2) "A software error...may cause an unexpected application of brakes," the NHTSA stated in its announcement regarding the larger recall. For the second issue, the agency confirmed a defect in the hybrid power control unit (HPCU) can cause overheating, "increasing the likelihood of a fire."
(P3) The first recall affects 421,078 vehicles over a software glitch in the braking system. A second, unrelated recall covers 54,337 Hyundai Elantra Hybrid sedans from the 2024 through 2026 model years due to a fire risk stemming from the HPCU, which is responsible for managing the car's electrical energy.
(P4) These back-to-back recalls could prove costly for Hyundai, not just in direct repair expenses but also in potential damage to its brand reputation for safety and reliability. The issues put a spotlight on an industry-wide challenge: managing the software and component-level risks that now represent a major source of vehicle recalls, a problem also faced by competitors like Ford and Toyota.
Software Bug Triggers Sudden Braking
The largest of the two recalls involves 421,078 vehicles across multiple Hyundai models, although the specific models were not immediately disclosed. According to the NHTSA filing, a software error is the culprit, potentially causing the vehicle's brakes to apply suddenly and unexpectedly. This could increase the risk of a crash, although no incidents or injuries have been linked to this specific issue so far. Hyundai has stated it will deploy a software update to the affected vehicles to correct the logic.
Elantra Hybrids Face Fire Risk
In a separate action, Hyundai is recalling 54,337 Elantra Hybrid sedans. The issue lies with the hybrid power control unit, where a semiconductor component can overheat under high electrical loads. The investigation traced the problem to software logic that fails to provide adequate cooling, which can lead to heat buildup and damage.
Hyundai reported four related incidents in the U.S., including one vehicle fire. No crashes or injuries have been reported. The fix involves a software update to better regulate the HPCU's temperature. Owners will be notified starting July 13 and are advised to park their vehicles outdoors until the repair is completed.
