McLaren Recalls All Sennas In The U.S. Over Wiring Harness Problem

McLaren has announced that it is recalling all examples of the Senna in the United States, shortly after it announced a separate recall for models in Australia for the exact same reason.

A recall notice issued by the National Traffic Highway Safety Administration (NHTSA) says a branch of the vehicle engine wiring harness could come into contact with a metal link pipe heatshield. If there is contact, the harness could become chafed, potentially breaching the harness heatshield wrap and the harness outer sleeve.

McLaren believes this could lead to damage to the wires contained within the engine harness bundle.

The British carmaker says a number of things could happen as a result of the chafing. For example, the track-focused hypercar could enter limp mode, power from the engine could be reduced, the engine may stall, the engine may misfire, and unburnt fuel in the catalyst could “lead to increased temperature of the catalyst.”

McLaren adds that if the driver does not turn off the engine, unburnt fuel could continue to enter the catalyst, meaning a rupture to the exhaust system cannot be ruled out – this would allow hot gas to escape into the engine bay and “could cause consequential damage to the car.” Reading between the lines, it means that a fire could be triggered.

Resolving the issue will be a simple matter of re-touting the wiring harnesses so that it does not touch the link pipe heatshield. McLaren says it is not aware of any incidents relating to the issue. However, at least two Sennas have caught fire since deliveries started last year.
