How do Chinese EVs handle over-the-air recalls and safety fixes?
OTA recall capability turns what used to be a multi-week logistics headache into an overnight download. Here's how it works in practice.
Recent OTA recall history
Xpeng, June 2024 — G9 ABS calibration on 47,000 units, delivered as v4.5.7 firmware.
BYD, March 2024 — 96,000 Han/Tang BMS parameter refinement, delivered as DiLink 4.2.11.
NIO, August 2024 — ET7 lane-change confidence tuning across 44,000 units.
Tesla, comparison — dozens of OTA recalls per year; industry pioneer.
What can and cannot be OTAd
- OTA: BMS parameters, brake logic, ADAS behaviour, infotainment security patches, powertrain calibration
- Not OTA: hardware defects (contactor replacements, coolant pump), physical fittings (seatbelt anchors, mounts), high-voltage isolation issues requiring inspection
Regulatory oversight
In China, SAMR requires OEMs to file OTA-recall notifications identically to hardware recalls.
In Europe, KBA (Germany) and DVSA (UK) have accepted OTA recall as compliant with UN R156 (Software Update Management).
- 01Most safety fixes are delivered overnight, no dealer visit.
- 02Regulators accept OTA recalls as fulfilling notice.
- 03Hardware faults still need physical service.
