Rivian Automotive is recalling 27,882 of its R1S and R1T electric vehicles after identifying a defect in the front turn signal lamps that could lead to failure during operation. The issue, linked to components supplied by Myotek North America, was found to violate U.S. federal safety regulations.
The affected vehicles include 2025 model year R1S units produced from April 29, 2024, to May 13, 2025, and R1T units manufactured from July 10, 2024, to May 13, 2025. An internal investigation launched earlier this year revealed that the signal lamps may fail due to an unspecified internal malfunction, prompting the recall.
According to Rivian, a noncompliance with Federal Motor Vehicle Safety Standard (FMVSS) 108, which regulates automotive lighting and signaling systems, was identified. The malfunction does not cause the vehicle to lose power or control, but a failed turn signal lamp will not illuminate, reducing the vehicle’s ability to signal lane changes or turns. When a lamp fails, the vehicle’s system alerts the driver with a warning message and speeds up the blinking of the remaining signal lamps.
Although no accidents or injuries have been linked to the issue, Rivian is moving ahead with a remedy, which involves replacing the defective signal lamps with updated components. Owners will be notified by mail no later than July 25, 2025. The availability of replacement parts has not yet been confirmed.
The R1T and R1S models are manufactured at Rivian’s plant in Normal, Illinois. Originally opened as part of a Mitsubishi-Chrysler joint venture, the facility was acquired by Rivian in 2017. The company recently announced slight price increases for the 2026 model year, along with the addition of a NACS charging port.
