The defect
McLaren Automotive Incorporated (McLaren) is recalling certain 2019-2020 600LT Coupe and Spider vehicles. The joint between the temperature sensor housing and the hose from the outboard radiator may not be sealed properly, which can result in coolant leaking into the engine compartment.
The risk
A coolant leak in the presence of an ignition source, such as hot engine components, can increase the risk of a fire.
