News Agency NewsOn December 1, Netcom learned from the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China that some imported Lexus RX had potential safety hazards due to imperfect fuel injection correction control procedures in the engine electronic control unit (ECU) and insufficient pressure resistance of internal parts of the high-pressure fuel pump. Toyota Motor (China) Investment*** has decided to recall some imported RX vehicles produced between November 30, 2018 and March 1, 2021, with a total of 88,545 units. A total of 68,434 imported RX vehicles manufactured between September 4, 2018 and September 6, 2022 are being recalled.
Scope of the recall, make, and model
Reason of the recall:
1) The vehicles within the scope of this recall may be lower than expected due to the imperfect fuel injection correction control program in the engine electronic control unit (ECU), resulting in the actual fuel injection volume of the engine may be lower than the expected value, resulting in unstable engine speed during cold start, and in extreme cases, the engine will accidentally shut down when the vehicle is driving at low speed, increasing the risk of being rear-ended, and there are potential safety hazards.
2) Due to the insufficient pressure resistance of the internal parts of the high-pressure fuel pump, the internal wear of the fuel pump may occur in the vehicles within the scope of this recall, resulting in cracks in the welding parts of the fuel pump due to stress concentration. In extreme cases, fuel may leak through cracks, and there is a risk of exposure to external ignition sources. At the same time, fuel leakage and volatilization have unreasonable emission hazards.
Recall Measures:
1) Toyota Motor (China) Investment*** will upgrade the engine ECU control program for the vehicles within the scope of the recall free of charge to eliminate potential safety hazards.
2) Toyota Motor (China) Investment will inspect the high-pressure fuel pump for the vehicles within the scope of the recall free of charge, and replace the parts that do not meet the requirements with the improved high-pressure fuel pump to eliminate potential safety hazards and unreasonable emission hazards.
