Recalls
McLaren Automotive Incorporated (McClaren) is recalling certain 2020-2025 600LT, 720S, Artura, GT, and GTS vehicles. The brake lines may be routed incorrectly and cause the brakes on the incorrect side to activate, possibly resulting in one of the rear wheels locking up.
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.
