NHTSA Complaint #11708078 — 2026 RIVIAN R1S

I have had siginificant issues with my new 2026 rivian R1S specifically based around two key areas: 1. inaccurate battery range reporting/capacity below 20% charge 2. inaccurate mapbox navigation. Those two issues combine to create a dangerous situation in extreme conditions for a vehicle specifically designed and marketed for off-road adventure (snow, rain, below freezing temperatures) and for large capacity (7 passengers). These two issues have left me and my family stranded three different times in remote locations in spite of our best efforts to keep the vehicle well charged and cross referencing navigation with other apps. I have taken the vehicle to Rivian service twice already and I was assured that the software update 38.30, but that is not the case. This left me stranded in Lone Pine, California where I had to abandon the vehicle and have it towed back to the Burbank service center and again near Mt. Shasta, California. Both were in December 2025, in sub-freezing conditions at night after repeated charging attempts. This created additional issues where the 12V battery charge ran down, the vehicle couldn’t get into Neutral to be towed and in all cases, Rivian roadside assistance was not able help beyond scheduling a service appointment.
