  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.
