Car Software, Safety Ratings and Recalls — 2026-09-16
China has introduced a new national standard formally bringing Over-the-Air (OTA) software updates into the vehicle recall regulatory framework, ending the era of "silent fixes." In the US, Toyota issued a critical software recall for its new C-HR EV due to a battery management defect, while Euro NCAP awarded five-star safety ratings to several Chinese electric vehicles, including the Leapmotor B05 and BYD ETT truck.

China’s New Standard Ends "Silent" OTA Fixes
On September 16, 2026, reports confirmed that China’s State Administration for Market Regulation (SAMR) has finalized a new national standard for automotive software quality and defect management. This regulation explicitly categorizes OTA remote upgrades used to fix safety defects as formal recalls, requiring manufacturers to notify regulators and owners rather than pushing silent patches. This move aims to prevent automakers from hiding software flaws behind minor version updates and ensures that software defects are treated with the same rigor as mechanical failures.
Toyota C-HR EV Recalled for Battery Management Software Defect
Toyota issued a safety recall for approximately 8,500 to 10,000 units of the 2026 C-HR Electric Vehicle in North America on September 11, 2026. The recall addresses a defect in the BEV ECU (Electronic Control Unit) software related to regenerative braking logic, which can lead to battery overcharging and a potential loss of drive power. While the fix is a software update available at dealerships, this incident highlights the risks associated with early-stage EV software integration and the importance of robust OTA testing protocols.
Euro NCAP Awards 5 Stars to Leapmotor B05 and BYD Electric Truck
Euro NCAP released updated safety ratings on September 16, 2026, awarding five stars to the Leapmotor B05, a compact EV from the Stellantis-backed Chinese brand. Additionally, the BYD ETT 44, a long-haul electric truck, became the first commercial EV to receive a five-star rating from Euro NCAP, setting a new benchmark for safety in heavy transport. These results underscore the rapid improvement in safety engineering among Chinese manufacturers, challenging traditional European and Japanese benchmarks.
Nissan and Mitsubishi Issue Brake and Instrument Cluster Recalls in Japan
In Japan, Nissan filed a recall on September 10, 2026, for 36,766 units of the Caravan and Isuzu Como models due to brake component defects that could increase stopping distance. Separately, Mitsubishi Motors recalled 21,584 Delica vehicles on the same date due to a control program bug that could cause the instrument cluster display to fail. These mechanical and software-related recalls highlight ongoing quality control challenges for legacy automakers even as they transition to electrified platforms.
Local view
In China, local tech media and consumer platforms are heavily discussing the new SAMR regulation, with outlets like Smzdm and Automachi emphasizing that the rule prevents manufacturers from bypassing recall responsibilities via OTA updates. The narrative focuses on consumer protection and the end of "half-finished" vehicles being sold with promises of future software fixes.
In Japan, Response.jp and TruckNews.biz covered the Nissan and Mitsubishi recalls, focusing on the specific impact on commercial fleets and the urgency of brake-related repairs for safety compliance.
Context & numbers
- Recall Volume: The Toyota C-HR EV recall affects approximately 8,500–10,000 vehicles in North America.
