    Steering Knuckle Heat-Treatment Defect Leads Tesla to Recall More Than 20,000 Model Y Vehicles

    Steering knuckles supplied by Tuopu Group may have insufficient strength, deform, or even fracture due to insufficient water level in the heat-treatment quenching tank; Tesla recalled 21,599 Model Y vehicles in China and 826 in the United States, sparking controversy over the division of inspection responsibilities between the automaker and the supplier. The subsidiary was also fined 100,000 yuan twice, in 2021 and 2023, for nonstandard hazardous waste storage. Recall; environmental administrative penalty.

    Top Group discloses a steering-knuckle manufacturing issue linked to the Model Y recall

    Hazard disclosure

    Top Group said a low water level in a quenching tank on a heat-treatment production line left some parts incompletely quenched, potentially causing steering knuckle strength to fall below design requirements. It reported an estimated defect probability of 0.2%–1.0% among the suspect batch and said the affected parts were supplied only for Model Y vehicles.
