Summary
Rivian is initiating a customer satisfaction campaign for some model year 2027 R2 vehicles that may have been built with a south/rear multifunction module that was incorrectly assembled by the supplier. This condition may result in a reduction of electrical isolation and a corresponding malfunction indicator on the driver display informing the driver that the vehicle requires service. In rare instances, the driver will receive a notification to pull over safely and the vehicle will enter a reduced performance safe-state mode. Rivian will inspect the south/rear multifunction module and replace the south/rear multifunction module or the HV battery energy management control module. Rivian is launching this campaign for customer satisfaction and to ensure the quality of Rivian vehicles.

Owners of these vehicles have filed 1 complaints in the electrical category.
