McLaren has to recall 15 vehicles in Germany. More than 180 vehicles are affected worldwide.
The Federal Motor Transport Authority (KBA) has the car manufacturer McLaren recall 15 vehicles in Germany. More than 180 vehicles are affected worldwide. The National Highway Traffic Safety Administration (NHTSA) is recalling 164 vehicles in the United States. ,
The cold-formed nuts of the high-pressure fuel lines may become loose from the male-threaded outlet connection of the gasoline direct injection fuel pump when subjected to vehicle loads, particularly during dynamic driving maneuvers commonly associated with track driving.
If the nut loosens, fuel may leak out. The fuel line is located near engine components that have high operating temperatures. If fuel is released near these components, thermal activity can result.
This model is affected by the recall:
(US: 164 vehicles /Germany: 15 vehicles)
McLaren will replace the high-pressure fuel lines, fitted with 15mm cold-formed rolled-thread nuts, with new high-pressure fuel lines, fitted with fully machined 16.5- mm nuts are equipped with a cut thread. This remedy will be carried out free of charge for the customer. Fully machined nuts with cut threads have a higher coefficient of friction than cold-formed nuts with rolled threads.
The KBA reference number is 012370, the manufacturer code of the recall campaign 2022/002. The recall can be found at NHTSA under case number 22V-908.
Conclusion
McLaren has to make improvements to over 180 Artura vehicles worldwide. The cold formed nuts of the high pressure fuel lines can potentially work loose from the male outlet connection of the gasoline direct injection fuel pump.
