Service bulletin RSB-52-26-001-1

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 2027 R2 vehicles with roof glass that does not provide optimal protection from high solar loads on sunny days. Upon customer complaint of high interior temperatures from sun exposure through the roof glass, Rivian will replace the roof glass with a version that reduces solar load.
