Car Software, Safety Ratings and Recalls — 2026-09-18
China has introduced a new national standard explicitly bringing Over-the-Air (OTA) software updates under formal recall regulations, closing loopholes for "silent" fixes. Meanwhile, Toyota issued a significant recall for its 2026 C-HR EV due to a battery management software defect that can cause drive power loss, highlighting the persistent risks in early-stage electric vehicle software integration.

China’s New National Standard Brings OTA Updates Under Recall Regulations
On September 16, 2026, Chinese regulators announced a new national standard for automotive software quality and defect management. This regulation explicitly categorizes OTA remote updates as part of the recall process if they address safety-critical defects, preventing manufacturers from using software patches to bypass formal recall reporting and liability. The move is designed to stop automakers from releasing "half-finished" vehicles and fixing them quietly via the cloud without consumer notification or regulatory oversight.
Toyota Recalls 2026 C-HR EVs for Critical Battery Software Flaw
Toyota issued a recall for approximately 8,521 units of the 2026 C-HR Electric Vehicle in the US (NHTSA campaign 26V570000) on September 11, 2026. The defect lies in the Battery Management System (BMS) software, which can incorrectly calculate state-of-charge during regenerative braking, leading to potential battery overcharging and sudden loss of drive power. Dealers will perform a software update to correct the logic, marking one of the first major recalls for Toyota’s new dedicated EV platform.
Leapmotor B05 Achieves Five-Star Euro NCAP Rating
On September 16, 2026, the Leapmotor B05, a new electric crossover from Stellantis’ Chinese partner, was awarded five stars in Euro NCAP tests. The model scored highly in adult occupant protection and vulnerable road user protection, reinforcing the trend of Chinese EVs achieving top-tier safety ratings in Europe. This result follows similar five-star awards for the Aion UT and Geely E2 earlier this month, challenging traditional European and Japanese competitors on safety benchmarks.
Nissan Issues Large-Scale Brake Recall for Caravan and Como Vans
Nissan filed a recall with Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) on September 10, 2026, affecting 36,766 units of the Caravan and Isuzu Como vans. The defect involves brake components that may degrade, leading to increased stopping distances. While not a software issue, this large-scale mechanical recall underscores the ongoing safety scrutiny of commercial vehicle platforms in Asia, which often share components across multiple brands.
Local view
In Germany, the ADAC (Allgemeiner Deutscher Automobil-Club) has publicly welcomed Euro NCAP’s updated testing protocols, which now include stricter requirements for Assistive Systems (ADAS) and low-speed crash tests. ADAC officials argue that these changes are necessary to reflect the increasing complexity of software-driven safety features and to ensure that "five-star" ratings remain meaningful for consumers navigating the transition to autonomous driving capabilities.
Context & numbers
The global automotive software market is projected to reach $57.7 billion by 2034, driven by the shift to Software-Defined Vehicles (SDVs). However, the regulatory landscape is tightening: China’s new standard mandates that any software defect affecting safety must be reported as a recall, not just patched silently. In Japan, the MLIT continues to process high volumes of recalls, with recent filings covering everything from Scania truck transmissions to Nissan van brakes, indicating no slowdown in physical safety defects despite the software focus.
On the radar
- Honda-Nissan Software Integration: Reports indicate that Honda and Nissan are moving toward a unified software architecture for their joint ventures, aiming for implementation by fiscal year 2029. This could significantly alter how ADAS updates are deployed across their combined fleets.
- NHTSA RAB Proposal: NHTSA is still processing comments on its proposal to add Rear Automatic Braking (RAB) with pedestrian avoidance to its recommended ADAS list, which could influence future NCAP scoring weights.
