Nio files China recall for 686 Firefly EVs over steering sensor interference

What Happened
Nio's Anhui-based vehicle technology unit has filed a recall plan with China's market watchdog, covering 686 Firefly battery-electric cars. The plan took effect the day it was filed, September 18, 2026. Only cars assembled between March 20 and April 2, 2026 are included in the campaign, which carries recall number S2026M0114V.

Recall S2026M0114V, filed with China's market regulator on September 18, 2026.
The regulator's notice traces the problem to an abnormal fluctuation in the manufacturing process, which may allow the wiring harness of the steering column torque sensor to interfere with the sensor rotor. In an extreme case that produces an irregular sensor signal, the electric power steering warning lamp lights up and steering assistance is lost, the filing says. Nio's submission to the regulator describes that outcome as a safety hazard.
- Inspect the steering column torque sensor wiring harness and rotor for interference, free of charge.
- Replace the sensor wiring harness if interference is found.
- Skip the inspection on vehicles that have already had the relevant repair work done.
The regulator says Nio will arrange the recall service through its app, text messages and calls. CnEVPost also identifies the company by its NYSE ticker, NIO.

Why this matters
If the steering column sensor is disturbed, the car's electric power steering can stop helping the driver, which makes the vehicle harder to control — so the defect is a safety matter for the 686 owners involved. The notice also shows how China's market regulator publicly documents automaker recalls and how owners are contacted directly rather than through dealers.
