The 2019 McLaren Senna has 2 recalls, the most serious involving a foam pad beneath the fuel tank that traps moisture, corrodes the tank, and can cause a fuel leak that may ignite.
The second recall concerns an engine wiring harness that can rub against a metal heat shield over time, wearing through the insulation and damaging the wires underneath. If the wires are damaged, the engine can suddenly lose power or stall without warning.
