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.
Risk: A coolant leak in the presence of an ignition source, such as hot engine components, can increase the risk of a fire.
Fix: Dealers will replace the coolant hose, temperature sensor housing, and constant pressure clamp, free of charge. Owner notifications letters were mailed September 7, 2023. Owners may contact McLaren customer service at 1-646-429-8916.

Defect: McLaren Automotive Incorporated (McLaren) is recalling certain 2020 570S, GT, 2019 600LT, and 2019-2020 720S vehicles. The brake assembly banjo bolt may be missing the holes that supply brake fluid to the caliper, which would cause the brakes to fail on one corner of the vehicle.

Fix: Dealers will inspect and replace the banjo bolt, as necessary, free of charge. Owner letters were mailed September 1, 2021. Owners may contact McLaren customer service at 1-646-429-8916. McLaren's number for this recall is SRC 00 C 001.
