Service bulletin RSB-26-26-001-1

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

Rivian is launching a technical service bulletin for some model year 2022-2024 R1T and R1S vehicles that may be susceptible to water ingress in the front HVAC assembly. This may result in damp or soggy carpets in the front of the vehicle. Upon customer complaint of wet carpet in the front of the vehicle, Rivian will inspect the component and replace any damaged parts, and reseal the case to prevent further water ingress.
