The 2020 McLaren GT has 6 recalls, the most serious involving two separate brake defects: a banjo bolt that may block brake fluid from reaching one caliper, and brake lines that may be routed to the wrong side, causing a rear wheel to lock unexpectedly.
The braking issues together mean the car can pull hard to one side or snap into a skid with little warning. On the fuel system side, foam padding beneath the fuel tank can trap moisture, corrode the tank, and cause a fuel leak that raises fire risk near any ignition source. The hood latch is also affected: an overtensioned release cable can cause the hood to fly open while driving and block the driver's view entirely. Rounding out the list, the driver's airbag may be improperly connected to the restraint controller and fail to deploy in a crash.
