BYD to recall nearly 90,000 hybrids in China over battery defects

BYD will issue a software update to nearly 90,000 plug-in hybrid vehicles in China after regulators identified manufacturing defects in battery packs that could pose safety risks.

The recall affects 88,981 Qin Plus DM-i sedans made from January 2021 to September 2023, after an investigation by the State Administration for Market Regulation.

Authorities found the battery packs had consistency issues from production, which could restrict power output and, in rare cases, prevent the vehicles from running in pure electric mode.

BYD plans to deliver a remote over-the-air update, and will monitor for any further issues.

If a fault is detected, a warning light will alert drivers, and BYD will replace the battery pack at no cost.

The affected vehicles represent about 20% of BYD’s sales in October.

🧠 Food for thought

Implications, context, and why it matters.

BYD’s battery recall reveals wider quality control problems in China’s New Energy Vehicle (NEV) market

The move follows BYD’s October recall of over 115,000 Tang and Yuan Pro models for design defects plus battery safety risks 1, so two actions this close reveal a recurring quality problem.
By the end of September 2025, China had run 3,230 recalls covering 120 million vehicles 2.
The affected cars were built over 2.5 years 3. That gap means the factory missed the issue for a long stretch.
BYD sold 3.7 million vehicles from January to October 2025 4. The recall covers about 2.4% of that period, yet the long production run raises doubts about quality controls during fast expansion.

Third-party over-the-air (OTA) compliance and battery analytics can serve China’s growing recall system

China now requires filing for OTA updates, with core functions such as autonomous driving needing product change permits 5.
New standards for intelligent connected vehicles on software updates and data storage take effect Jan. 1, 2026 6.
Original equipment manufacturers (OEMs) must report accidents within 24–48 hours, plus certain driver-assistance software events each quarter to MIIT and SAMR 5. That creates room for automated reporting and analytics.
Battery monitoring vendors can serve automakers and fleets 7. They can also work with insurers and used car marketplaces by spotting anomalies before they become safety risks 7. OTA installation rates could approach 90% by 2030 7.
