When the third row seat motor fails in your 2023 Rivian R1S, you lose the ability to electrically fold or deploy the rear seats, affecting cargo flexibility and passenger accommodation. These power-operated seats are convenient but contain motors and mechanisms that can fail.
Understanding R1S Third Row Seats
The R1S features power-folding third row seats that can be lowered for additional cargo space or raised for passenger seating. Electric motors control the folding mechanism, with controls on the seats, cargo area, and touchscreen. The system includes position sensors and safety locks.
Common Causes of Motor Failure
Electric motor wear or failure prevents movement. Mechanical binding from debris or misalignment blocks the mechanism. Electrical issues prevent power from reaching the motor. Control module faults stop commands from executing. Obstruction detection may prevent operation if something is sensed in the seat path.
Troubleshooting Steps
Remove any cargo or items that might be blocking the seat path. Try operating via touchscreen and physical seat controls. Listen for motor sounds when commanding seat movement—no sound indicates electrical issue, grinding indicates mechanical binding. Check for error messages related to seats on the display. Perform a vehicle system reboot.
Manual Operation and Service
If the seat is stuck in an unusable position, manual release may be possible—check the owner's manual for emergency release procedures. Don't force seats that are mechanically bound—this can cause additional damage. Schedule Rivian service for motor replacement or mechanism repair. Seats stuck flat may still allow partial vehicle use, but stuck-up seats significantly impact cargo space.
