NHTSA Complaint #11635538 — 2025 RIVIAN R1S

Driving my Rivian R1S on a road trip with family from Seattle, WA to Ketchum, ID (about 600miles.) Stopped to recharge outside of Boise, ID for about 20mins. Started driving again and in about 5 minutes the car started warning (visual message and audible alarm). The following events then occurred: -- The warning message stated something along the line of "Pull over immediately the car will shut down imminently." -- I was driving in traffic and was able to make it through an intersection and saw a gas station in the distance. -- The power steering and braking began to go unresponsive and the car began slowing down as I drove through the intersection. I tried to guide the car to the gas station. -- While pulling in to the gas station the car could barely be controlled. Once dropping below 5mph or so it immediately shut itself down. -- The inability to effectively control the vehicle was extremely unsafe. If the intersection I had to pass through had a red light the car would likely have shut itself down and stranded our family at a very busy intersection. -- The car began flashing a ton of different warning messages. "Suspension needs to be serviced", "Front trunk unable to close please service", "Battery system overheating" are a few as an example. -- After calling customer service I reset the vehicle (using prescribed sequence of button pushes.) The car then went dark and nothing worked from there out. -- Called a tow truck and found hotel for family. Rivian was towed to the Boise service center. -- Rivian service center has been unable to diagnose or recreate the issue to date - they have been in possession of the vehicle for 17 days and counting.
