The 2023 McLaren Artura has already been recalled over possible loose nuts that could cause a fuel leak, though the issue only affects a small number of cars in the US
According to a National Highway Traffic Safety Administration (NHTSA) recall report, high-pressure fuel lines on the recalled vehicles are equipped with cold-formed, rolled-thread nuts that can separate from the connection with the fuel pump, thereby causing a fuel leak. The connection point where nuts could loosen is near engine components that get hot and could be a source of ignition, the report said.
The problem lies with the type of nut used, according to McLaren. The cold-formed, rolled-thread nut used on the affected vehicles may have too low a coefficient of friction to ensure a reliable connection, which the automaker says is due to the manufacturing process of the affected nuts. Some cars were fitted with fully machined nuts and are not affected by the recall.
The recall report said 164 cars may be affected, however McLaren spokesman Roger Ormisher told the Motor Authority fewer than 50 cars in customer hands were likely to be affected, with the rest either en route or part of McLaren’s internal fleet.

Dealers will replace the high pressure fuel line free of charge. McLaren uses its production records to determine which cars are affected by the issue, but has not discussed a timeline for notifying owners when they need to turn in their cars for this repair.
The Artura plug-in hybrid was first shown in 2021, but deliveries to customers didn’t start until the middle of this year. McLaren confirmed earlier this month that it has sold some historic cars from its historic collection to pay for the development of “certain technical upgrades” for the Artura, which is the first McLaren to go complete since the MP4-12C supercar almost a decade ago was developed from scratch.
