The 2019 McLaren 600LT has 3 recalls, the most serious being two separate coolant leak risks that can lead to an engine bay fire if leaking fluid contacts hot engine components.
Both cooling system issues involve joints that may not seal properly, allowing coolant to escape into the engine compartment while the car is in motion. Prior repair attempts did not fully resolve the issue, which is why two separate filings address what is essentially the same fire risk. On the braking side, a brake caliper banjo bolt may be missing the internal holes that allow brake fluid to reach one corner of the car. With no fluid pressure at that corner, the brakes can pull hard to one side under hard stopping, raising the risk of losing control.
