Rivian Expands Turn-Signal Recall to Nearly 3,830 EVs After Supplier Missed Bad Parts
A parts supplier's failure to fully quarantine defective turn-signal lamps means the fix Rivian issued last year didn't catch every affected R1S and R1T.

AutomotiveThe short answer
- Rivian is recalling 3,829 R1S and R1T vehicles because front turn-signal lamps may fail to illuminate.
- The defect traces back to supplier Myotek, which didn't fully quarantine lamps already flagged in a June 2025 recall of the same part.
- Rivian estimates only about 0.6% of the newly recalled vehicles actually have the flawed lamp, and it has not received reports of crashes or injuries.
- Owners will be notified by September 29, 2026; dealers will inspect and, if needed, replace the lamps at no cost.
Rivian is recalling 3,829 R1S and R1T electric vehicles because their front turn-signal lamps may fail to illuminate — the second time in 14 months the automaker has had to address the same underlying part. The company says a supplier's failure to fully quarantine defective lamps after an original June 2025 recall let some of the bad parts slip into vehicles built as recently as May 2026.
What's affected
- 3,204 R1S units built between June 12, 2024 and May 26, 2026
- 625 R1T units built between October 1, 2024 and March 19, 2026
- Front turn-signal lamps supplied by Myotek that may not illuminate, which violates a federal lighting standard (FMVSS No. 108)
- Warning signs include a dashboard alert reading "Turn signal lights not working. Service it soon," along with faster-than-normal blinking and clicking
Why the first fix didn't catch everything
Rivian's original recall, filed with NHTSA in 2025 as recall 25V387, was supposed to address this exact defect. According to the automaker, the supplier didn't properly quarantine suspect lamps from that manufacturing run, so some defective parts kept shipping and ended up installed in additional vehicles built afterward. That's what triggered this second, expanded recall rather than a brand-new defect.
What owners should do
Rivian says it will notify affected owners by September 29, 2026, and dealers will inspect the front turn-signal lamps and replace them free of charge if needed. The company estimates that only about 0.6% of the recalled population — roughly 17 vehicles' worth of confirmed failures were logged between June 2025 and July 2026 — actually has the defective part, and it has not received any reports of crashes or injuries linked to the issue.
