Summary

Rivian is initiating a customer satisfaction campaign for some model year 2022 R1T vehicles that may experience a rear wheel liner wire harness (electronic parking brake and wheel speed sensor) pulling out of the harness holder during full wheel droop, allowing the harness to be out of position and contact the inside of the wheel. If the harness rubs through it could cause a loss of electronic parking brake and/or wheel speed sensor for that wheel. This could result in decreased parking brake performance. This condition was discovered after the off-road portion of a media event. The customer will receive adequate forewarning of this condition from the malfunction indicator lamp (MIL). Further, the vehicle will go into a limited performance mode and the electronic parking brake for the other wheel would still be able to hold a steep grade (20%) at GVWR. Installing cable ties will secure the rear wheel harnesses to the knuckle bracket to ensure retention. Rivian is launching this campaign for customer satisfaction and for the continuous improvement of Rivian vehicles.

Owners of these vehicles have filed 15 complaints in the driver assistance category.
