Defect: McLaren Automotive Incorporated (McLaren) is recalling certain 2018-2019 Senna vehicles. The engine harness may contact a metal link pipe heat shield, chafing the harness over time, potentially damaging the wires.
Risk: Damaged wires may cause a sudden reduction in engine power or an engine stall, increasing the risk of a crash.
Fix: McLaren will notify owners, and dealers will reroute the engine harness, free of charge. The recall began October 18, 2019. Owners may contact McLaren's Client Services department at (855) 202-8815 or clientservicesna@mclaren.com.
Service bulletins (33)
Technical service bulletins are repair instructions manufacturers send dealers for known issues. Unlike recalls, the fix is not automatically free — but naming the bulletin at the service desk can save diagnosis time and support goodwill repairs.
