2025–2026 Rivian R1S and R1T Recall: Front Turn Signal Failure

Rivian is recalling 3,829 R1S and R1T vehicles from model years 2025–2026 because one or both front turn signals may fail to illuminate and flash. Nonfunctioning turn signals increase crash risk. Campaign 26V508000 expands the earlier recall 25V387.

What the recall means for owners

RIVIAN: R1S, R1T

Rivian will inspect the front turn signals and replace them as necessary, free of charge. Owner notification letters are expected September 29, 2026. The official record identifies the expanded campaign as FSAM-1833; an earlier recall notice alone does not establish the current status of a particular VIN.

What owners should do next

Contact Rivian service about FSAM-1833 and ask whether your VIN is included in the expanded campaign, especially if you received information about 25V387. Rivian customer service is 1-888-748-4261.

R1S and R1T owners should also review the separate Rivian rear-visibility software recall and check each campaign independently by VIN.

Use the official NHTSA recall lookup or contact the manufacturer or an authorized dealer to confirm recall status for your vehicle’s VIN. A matching model and year alone do not establish that a vehicle is included or that its repair is complete.
