McLaren must recall every 2019-2020 600LT it sold in America after discovering that a design flaw could allow coolant to leak on the engine, potentially leading to a fire

The McLaren 600LT does everything you would expect a supercar to do. Thanks to a kerb weight of 2,859 lbs (1,297 kg) and a 3.8-liter twin-turbocharged V8 that makes 592 HP (600 PS / 441 kW) and 457 lb-ft (620 Nm), it’s a hell of a performer on track and, according to a recent recall notice, it can do the most supercar thing of all: catch fire.
McLaren has decided to launch a voluntary recall of every 600LT coupe and spider it sold in America for the 2019-2020 model years as a result of a design defect in the cooling system. In all, it will have to repair a total of 652 examples.
The automaker first became aware of the issue in December 2022, after a technician at one of its retail locations ran a regular audit. Their research determined that there was a risk of a coolant leak, prompting an investigation from the automaker.

It found that the risk of a leak in the 600LT was greater than in other models, and by June concluded that a design flaw was to blame. McLaren determined that the right-hand outboard radiator joint between the temperature sensor housing and the hose that runs from the radiator has inadequate sealing at the joint.
The loss of sealing can occur as a result of high vehicles loads and heat cycles, such as when the 600LT is driving quickly on a racetrack. If that causes a leak, coolant would be likely to land on engine components that have a very high operating temperature, and could result in a fire.
In order to prevent the issue from occurring, McLaren will install a new pressure clamp that can maintain the seal at the joint, and will not allow a leak to form. The remedy will be carried out at no cost to the owners.
