Known issues

Medium
2025 R1S/R1T traction-battery recall (NHTSA 25V-537) addressed an improperly grounded battery component that could cause loss of drive power. Rivian repaired affected vehicles free of charge.
Low
DC fast-charging speeds peak around 220 kW on Large Pack, tapering steeply above 80% SOC — normal for high-energy NCM cylindrical, not a defect.
Owner-fleet data
Low
Software updates (Gen2, mid-2024) materially changed battery preconditioning behaviour and improved fast-charge speeds. Owners on older firmware report different real-world charging.
Owner-fleet data
Low
Tow-mode range reduction is significant (50%+) due to vehicle weight and frontal area, not pack defect.
