According to the company's statistics, there are 595 vehicles in mainland China.
Some vehicles in this recall range have incorrect production parameters in the production of the third-row right seat belt pretensioner due to supplier manufacturing reasons, resulting in improper crimping of the casing for fixing the micro gas generator. If the vehicle collides and the seat belt pretensioner is triggered, the micro gas generator in the pretensioner may separate and enter the passenger compartment, increasing the risk of injury to the occupant; at the same time, the micro gas generator in the pretensioner will separate Reducing the protection effect of the pre-tightened seat belt on the occupant has potential safety hazards.

Compared to other rolling-element bearings, Slewing Bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
A slewing bearing or slewing ring is a rotational Rolling-Element Bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill.
Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.
Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used.
