Service bulletin RCA-18-25-001-1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

FSAM-1608: Rivian is initiating a customer satisfaction campaign for some model year 2023-2024 R1T and R1S vehicles. On these vehicles, the wheel hub to knuckle joint may have been serviced with a torque value that was too low. A fastener torqued to the lower value may cause an audible noise while driving at low speeds but will not impact vehicle performance. Rivian will retorque the affected fasteners and replace them if necessary. Rivian is launching this campaign for customer satisfaction and to ensure the quality of Rivian vehicles.
