2027 Rivian R2 Recall: Improperly Tightened High Voltage Fastener May Cause a Loss of Drive Power

A Rivian manufacturing operator found an under-torqued high voltage fastener on September 17, 2026, after an automated station had already tightened it. A week of investigation traced the same station's work to 14 Rivian R2 vehicles, all 2027 models built between May 18 and August 27, 2026. Rivian filed campaign 26V625 with NHTSA on September 29.

If the fastener is loose, the vehicle may lose motive power without prior warning. Rivian lists the share of the 14 with the defect at 100%.

NHTSA's records show two campaigns for the 2027 R2. The first, 26V597, was filed September 16, 2026 over a notification that could cover the rearview camera image, and took in 2,481 R2s alongside the R1S and R1T.

The Issue

The part is a bolt connected to the high voltage battery: an M6 flange bolt, 24.5 mm long, property class 8.8, Rivian part number SC00036202-D. The filing does not say which connection it secures, and the supplier fields are blank.

An automated station torqued the fastener, and the operator caught the under-torqued one afterward. Rivian has since reprogrammed the station to reject improperly torqued fasteners. The cause field of the report is empty.

Under warnings that can occur, Rivian entered "None."

Affected Models

Model	Model year	Production dates	Units
Rivian R2	2027	May 18, 2026 - Aug 27, 2026	14

Rivian identified the 14 from manufacturing records. Similar vehicles outside the campaign have properly torqued fasteners, the filing says. The R1S and R1T are not involved.

The camera campaign's R2 build window ran from April 23 to August 10, 2026, so an R2 built between May 18 and August 10 can fall inside both.

Chronology and Investigation

The investigation opened the day the operator found the fastener and ran through September 24, when Rivian decided on a voluntary safety recall of all 14 potentially affected vehicles. The report reached NHTSA five days later, and the agency acknowledged it on October 1. No NHTSA investigation preceded it.

Reported Incidents

As of the filing date, Rivian was not aware of any customer reports, accidents, injuries or fatalities related to the condition in any market. The report gives no warranty claim or field report count.

Remedy and Notification

Rivian will inspect the connection and repair it, or replace damaged components, at no charge. The remedy part is a properly torqued fastener, or replacement components with properly torqued fasteners. This is a hands-on repair at a Rivian service location or by mobile service; an over-the-air update does not apply.

Owner letters are expected to mail November 28, 2026, the same day the VINs become searchable on NHTSA.gov. Rivian sells and services direct, and the dealer notification field reads No Dealers. There is no interim letter.

Rivian's number for the campaign is FSAM-1888. NHTSA's record lists Rivian customer service at 1-888-748-4261.

Symptoms to Watch For

The filing names none, and says the loss of power would come without prior warning. With 14 vehicles involved, Rivian knows each one by VIN. An R2 owner with a build date between May 18 and August 27, 2026 can call Rivian with the VIN ahead of the November 28 letter.

How Long Will the Recall Repair Take?

Rivian has published no labor time. An inspection that finds the connection undamaged ends with the fastener torqued to specification. The filing also allows for replacing damaged components and does not say what those would be.

Bottom Line

Fourteen vehicles is a small campaign with a serious failure mode: drive power lost at speed, with nothing on the display beforehand. Rivian caught it on the line, has no report of it happening to a customer, and has not issued a do-not-drive advisory.

A Rivian manufacturing operator found the under-torqued fastener on September 17, 2026 after an automated station had tightened it; Rivian reprogrammed the station and recalled all 14 vehicles it had worked on. No customer reports, accidents, injuries or fatalities in any market as of the filing.

This is the second NHTSA campaign for the 2027 R2. The first, 26V597 of September 16, 2026, was a rearview camera software noncompliance covering 2,481 R2s and remedied over the air; this one covers 14 and requires a physical inspection.
