The 2020 McLaren GT has 6 recalls, the most serious being brake and hood issues that can cause loss of control or a sudden loss of forward visibility while driving.
The brake concerns fall into two distinct problems. On certain vehicles, a banjo bolt in the brake assembly may be missing the internal holes that route fluid to a caliper, leaving one corner of the car with no braking force. That imbalance can pull the car sharply to one side under hard braking. A separate issue involves incorrectly routed brake lines that can cause the wrong rear wheel to lock up, which can send the car into a spin. The hood recalls, which describe the same underlying problem across slightly different filing scopes, center on a release cable with excessive tension that can trip the latch on its own while the car is moving, throwing the hood open and blocking the driver's view entirely.
There is also a fuel system concern: moisture can become trapped in a foam pad beneath the fuel tank and corrode the tank itself over time, eventually opening a fuel leak that poses a fire risk near any ignition source. On the safety equipment side, the driver's airbag connector and the occupant restraint controller may be improperly mated, which can leave the driver's airbag deactivated and unable to deploy in a crash.
