Rivian Recalls Over 5000 R1 Vehicles After Halloween Software Update Interrupted Exterior Lights

EV startup Rivian Automotive RIVN recalled 5,128 units of its R1T trucks and R1S SUVs together owing to concerns about a recent software update disabling certain exterior lights, the National Highway Traffic Safety Administration (NHTSA) said on Wednesday.

What Happened: In the recalled model year 2025 vehicles, a particular software update, released on Oct. 15, prevented some exterior lights from turning on when the car costume feature was activated, the regulator said.

The car costume feature was released on Oct. 18 and the company identified on the same day that it was impacting the vehicles’ external lighting system and disabled the feature remotely. Deactivated exterior lightning, NHTSA said, reduces the vehicle’s visibility to other drivers, increasing the risk of a crash.

All vehicles were subsequently remedied on the same day. The company is not aware of any crashes, injuries, or fatalities owing to the issue, the regulator said.

The car costume feature was part of Rivian’s Halloween software update aimed at allowing customers to give their vehicles spooky costumes for a limited time as part of the festival.
