美国国家公路交通安全管理局(NHTSA)周一宣布,在日产汽车于6月发布召回后,将结束对454840辆日产汽车发动机故障问题的初步调查。
这项始于2023年12月的调查指控部分日产车型存在发动机故障导致动力丧失问题,消费者还报告了发动机爆震异响。美国汽车安全监管机构表示,若发动机内部部件脱落并损坏缸体形成破孔,可能导致机油接触高温表面引发火灾。
NHTSA数据显示共收到1878起事故报告,其中12起导致碰撞或火灾。调查涉及日产Rogue、Altima等车型及英菲尼迪QX50、QX55等豪华车型。
日产6月发布的召回方案要求经销商检查油底壳是否存在金属碎屑。未发现碎屑的车辆将根据发动机类型更换机油并进行小修;发现碎屑则可能需大修或更换发动机。这家总部位于横滨的车企还同意将受影响车辆的质保期延长至检测后10年或12万英里。
