Rivian recalled almost 28,000 R1S and R1T EVs last year for front turn signals that could fail to flash. Now it's recalling the recall. NHTSA campaign 26V508000, filed in August 2026, covers another 3,829 vehicles because the supplier tasked with pulling defective lamp assemblies off the line didn't quarantine all of them.
VINs for the new expansion became searchable on NHTSA.gov starting August 31, 2026. The remedy is the same as last time: Rivian service technicians inspect the front turn signal assembly and swap the lamp for free if it's one of the bad ones.
What Happened the First Time
Rivian filed the original recall, campaign 25V387, in June 2025. It covered 22,807 model year 2025 R1S SUVs and 5,075 R1T trucks, all built with front turn signal lamps supplied by Myotek under part numbers PT00882633 and PT00882632. An improperly manufactured lamp assembly could leave one or both front indicators unable to illuminate or flash, according to the recall filing, which is exactly the kind of failure that gets a driver rear-ended or side-swiped by someone who never saw the turn coming.
The fix at the time was straightforward: dealers inspect the assembly and replace flagged lamps. Rivian and Myotek treated the affected population as contained.
Why It's Back
It wasn't contained. Rivian's own filing for the new campaign says Myotek failed to properly quarantine every defective lamp after the original defect was identified, meaning some bad parts kept shipping and ended up installed on more vehicles anyway. That's a supplier-process failure layered on top of the original manufacturing defect, not a new kind of problem.
The expansion adds 3,204 more R1S units and 625 more R1T units, spanning the 2025 and 2026 model years. Combined with the original recall, just under 31,700 R1S and R1T vehicles have now been touched by this same lamp defect across two separate NHTSA campaigns.
The Two Campaigns Side by Side
| Detail | Original (25V387) | Expansion (26V508000) |
|---|---|---|
| Filed | June 2025 | August 2026 |
| R1S units | 22,807 | 3,204 |
| R1T units | 5,075 | 625 |
| Model years | 2025 | 2025, 2026 |
| Defect | Front turn signal lamp fails to illuminate/flash | Same defect, quarantine failure let more affected parts ship |
| Remedy | Free lamp inspection and replacement | Free lamp inspection and replacement |
Production dates for the newly added vehicles run from June 12, 2024, through May 26, 2026, for the R1S and October 1, 2024, through March 19, 2026, for the R1T. That range overlaps both the original recall's build window and months well after it, which is the clearest sign the quarantine genuinely failed rather than a few cars slipping through at the edges.
If You're Buying a Used R1S or R1T
A VIN that cleared the first recall isn't automatically clear of the second one. Rivian's own numbers show the expansion reaches vehicles built more than a year after the original campaign was filed, so "my car already got the recall fix" and "my car has no open Rivian recalls" are two different claims. Check the VIN again, even if a seller shows you paperwork from last year.
In CarScout's August 30, 2026 snapshot, there were 87 listings for the 2025 R1S nationally priced from $58,725 to $100,790, and 34 listings for the 2025 R1T from $56,641 to $94,697. Rivian's Gen 1 R1S and R1T have carried an unusually active recall history since launch, and this is another entry in that pattern rather than an isolated incident. Before you buy either one used, run the VIN through CarScout's free recall lookup tool to confirm every open Rivian campaign, not just this one, has actually been closed.
FAQ
How do I know if my Rivian is covered by the new recall? The expansion covers 3,204 R1S and 625 R1T vehicles from the 2025 and 2026 model years under NHTSA campaign 26V508000. VINs became searchable on NHTSA.gov on August 31, 2026. Check there or through Rivian's own recall lookup, since being cleared on the original 2025 campaign (25V387) doesn't mean you're clear of this expansion.
What's actually wrong with the turn signals? An improperly manufactured lamp assembly, supplied by Myotek, can prevent one or both front turn signals from illuminating or flashing as intended. Rivian says the supplier failed to fully quarantine defective lamps after the original 2025 recall, which is why more vehicles built into 2026 are affected by what is functionally the same defect.
Is this a sign Rivian's Gen 1 vehicles have ongoing quality problems? The R1S and R1T have drawn multiple recalls since their 2022 launch, covering everything from suspension components to seat belts to now this repeated turn signal issue. That doesn't make either one a bad used buy, but it does mean checking every open campaign against the specific VIN matters more here than it would for a car with a cleaner recall record.
