2025 Rivian R1S

I own a R1S and the vehicle is less than 900miles old (21st day of ownership). When driving today on the highway at 75miles - the vehicle suddenly decelerated to 51 miles. I almost got rear ended by a truck and was very difficult to manoeuvre to safe place from the left lane to the right most lane. I parked in a safe spot and saw through several customer Complaint forums that we need to do a hard reset. But the messages were from customers that are 3 years old. I am surprised this still exists as a complaint. I almost died today

Winter weather led to snow buildup on the headlamps which made them useless. Fortunately this was during the day so there was plenty of sunlight. If this was at night, I would not have had any visibility and would have needed to stop every few miles to clean the headlamps. My BMW uses washer fluid to clean my headlamps and the xenon's are hot enough to melt snow. Neither of these are in the Rivian

On November 16, 2024, while trying to use the vehicle's heating system, only cold air would come out of the vents and an error message, “thermal system fault” appeared on the screen. The service center instructed to not drive it and eventually picked it up via tow truck and made repairs. The vehicle was returned and hot air successfully comes out of the vents but it is often accompanied by extremely loud noises (like a jet engine) as well as some pulsating and odd noises. Also, periodically only cold air comes out of all vents (even though the screen shows heat) if the defog is selected with temperature and fan speed regulated. The safety and performance of the battery has been impacted by the faulty thermal management system.

On January 9, I was driving my new 2025 Rivian R1S (approx. 2,400 miles) when it suddenly displayed “Drive stalk not working.” The vehicle jolted, made a loud noise from the front axle, and then fully stopped in the middle of a busy road with the battery still at 55%. Once it stopped, I had no hazard lights or power steering, and the infotainment system locked up. After several attempts to reboot, the screen showed “Critical battery error” before shutting down completely. I was unable to move the vehicle or alert other drivers with flashing lights, creating a major safety hazard. It took about two hours for a tow truck to arrive. ## Component or System Failure: The vehicle’s propulsion system (drive controls) and electrical/hazard light systems appeared to fail simultaneously. The vehicle is currently at a service center for inspection and could be made available if needed. ## Safety Risk: Being stranded in the middle of the road without hazard lights or any way to move the car put myself and other drivers at serious risk. ## Reproduction/Confirmation: It has not been confirmed or reproduced yet by the service center. ## Inspection: The manufacturer’s service center is inspecting the vehicle. No other parties (police or insurance) have inspected it. ## Warning Lamps/Messages: There were no prior warnings. The “Drive stalk not working” error and subsequent “Critical battery error” appeared just moments before the vehicle stopped. I am reporting this because a sudden, total shutdown without hazard lights is a serious safety concern, especially on a busy road.

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.
