The engine harness may contact a metal link pipe heat shield, chafing the harness over time, potentially damaging the wires.
Damaged wires may cause a sudden reduction in engine power or an engine stall, increasing the risk of a crash.
What to do
McLaren will notify owners, and dealers will reroute the engine harness free of charge.
The manufacturer has not yet provided a notification schedule.
Owners may contact McLaren's client services department at (855) 202-8815 or clientservicesna@mclaren.com.
