Defect: 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.
Risk: A rear wheel locking condition may cause the driver to lose control of the vehicle, increasing the risk of a crash.
Fix: Dealers will inspect and correct the brake line connections as necessary, free of charge. Owner notification letters were mailed on April 21, 2025. Owners may contact McClaren customer service at 1-646-429-8916.

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.

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.
